Abstract
The article discusses the impact of hydro-meteorological conditions (HMC) on the operation
of weapons and military equipment (WME) and the training and conduct of combat operations
by troops taking into account the requirements of current NATO regulatory documents and
standards. The structure of the battlefield control system (BMC) is proposed, which contains a
unique location service for geodata and weather conditions in the design of the geo-information
subsystem of the BMS for units of the Ground Forces of the Ukrainian Armed Forces. In
addition, the procedure for assessing the HMC impact on the use of weapons and combat
capabilities of the troops according to suitability indicators and criteria in the decision support
system is proposed.
As a result, based on the critical assessments of the HMC, this will make it possible to:
Conclude and assess the situation.
Develop a typical set of protective actions and measures for ensuring hydro-meteorological
safety in troops' activities and operation of the WME in the area of combat operations.
Develop recommendations for choosing the optimal plan for the functioning of units and
units of the Armed Forces of Ukraine, taking into account the entire range of possible
weather conditions.

1. Introduction
In the current conditions of the development of the battlefield management systems (BMS),
management bodies can quickly, automatically and impartially receive information and perform a
multi-faceted analysis of the situation to support decision-making at all structural levels acquires
particular relevance. The effectiveness of troops' operation is significantly dependent on the correctness
of the assessment, among other aspects, of the weather. Modern computer and telecommunication
technologies provide ample prospects and services in matters of HMC evaluation. The objective
assessment and consideration of HMC are carried out using data provided by the units responsible for
hydro-meteorological support, one of the types of operational combat support. The ability to assess the
impact of weather conditions on personnel, equipment and weapons, terrain characteristics are now

partially implemented in battlefield management systems of advanced countries. In this process, the
emphasis is put on obtaining the data detailed both in terms of content (the battlefield management
systems of NATO countries consider about 40 different weather parameters) and in spatial (describing
to the level of individual areas) and temporal (weather forecast for three hours, and the assessment of
weather impact in short time perspective) weather aspects [1-6]. Another feature of these systems is the
widespread use of both special and general purposes Internet geo-data services and applying military
geo-information systems for data integration [7-10]. The new means of obtaining hydro-meteorological
information, methods of its assessment and the practice of its application in the BMS for units and
subdivisions of the Land Forces (LF) of the Armed Forces (AF) of Ukraine and, in particular, in military
geo-information systems (GIS) are still little known in Ukraine [11-13]. Therefore, existing
implementations of such systems require comprehensive analysis and adaptation to the realities of the
Armed Forces of Ukraine with the prospect of further refinement and performance [14-18].
2. The purpose of the article
This article aims to analyse the abilities of modern information technologies to solve one of the
essential tasks in the activities of military command, namely the analysis of the HMC. This task is part
of the battlefield decision-making process and is implemented using current information and
telecommunications technologies. A research of the requirements of NATO regulations and standards
in force in Ukraine related to HMC and geographic information services and Internet technologies for
obtaining and processing hydro-meteorological data is needed to achieve this goal.
We propose the structure of the battlefield management system, which contains additional geodata
service for estimation of HMC, and for analysis of their influence on the application of armament and
military equipment according to criteria of combat readiness of troops. The result should be an increase
in the efficiency and validity of decision-making, taking into account the impact of actual and projected
HMC on the functioning of troops, the use of weapons, training and combat operations of armies.
3. Related Works
Assessment of the HMC's influence on:
The planning and conduct of combat training activities,
The course of combat operations,
The effective functioning of weapons and military equipment,
Combat capabilities of troops.
They are components of the decision-making process, underestimating which complicates the
preparation and conduct of combat operations, which leads to significant non-combat losses, and in
some cases - to the disruption of the tasks in general [19-20]. However, the algorithms and methods
existing to support meteorological decisions in Ukraine do not always fully take into account weather
and climatic conditions. They do not always allow this information to develop optimal troops support,
perform aviation flights, choose combat methods and tactics, operate weapons, etc. [21-32]. One of the
areas proposed to determine the impact of current and projected HMC on the use of weapons, planning,
and direct management of units is to establish indicators and criteria for assessing the degree of hydro-
meteorological safety [15]. The implementation of planning tasks, their visualisation and delivery of
analysis results to users takes place in the environment of modern networked geo-information systems
for military purposes [26]. The reference literature also provides arguments favouring the rapid creation
of actual geo-information products (those created based on rapidly changing geo-data and
meteorological data) directly in the tactical chain. The especially applies to cases of hostilities in local
operations, actions in isolation from the main forces, conducting manoeuvring, and so on. This
conclusion is made from analysing actual hostilities currently taking place in Afghanistan, Syria, and
Ukraine [27]. We analysed the requirements of NATO standards to study military aspects of weather
[9, 13]. Modern solutions to the problem outlined above are based on the principle of using global
geodata services. Such services operate in the structure of specialised national agencies and
organisations. In the United States (USA), such an agency is NOAA [3-The National Weather Service
(NWS)]. A typical international data source is the International Civil Aviation Association (ICAO)
network of weather stations. Geo-information services, including those intended for defence and other
law enforcement agencies, use meteorological services of the above type [1, 3].
The services of ESRI, the developer of the ArcGIS geographic information system recommended
for implementation in the structure of the Armed Forces of Ukraine, can serve as a model here. In
particular, this company offers a software solution, "Military aspects of Weather", which converts
meteorological information into information about the effects of each aspect of the weather on personnel
and various types of military equipment and weapons according to expert opinions [4]:
-2: adverse;
-1: below the allowable (threshold state);
0: favourable.
For example, for the formal assessment of the effects of HMC on personnel, a cumulative review
(minimum value; maximum value; operational impact) is formed according to the following indicators
of variable weather: temperature; wind cooling; heat index (an indicator that combines air temperature
and relative humidity in shaded areas to establish the comfort of a person) (table 1):
Table 1
Rules for assessing the effects of weather on personnel
Weather Variable Minimum Value Maximum Value Operational impact
Temperature (°C)A -100 -26 -2
-26 -6 -1
-6 30 0
30 35 -1
35 100 -2
Heat Index -100 32 0
32 38 -1
38 51 -2
51 150 -3
Wind cooling (°C) 4 100 0
-6 4 -1
-17 -6 -2
-28 -17 -3
-58 -28 -4
-100 -58 -5
A total of 40 weather parameters are assessed for such entities as personnel, air defence forces
(ADF), uncrewed aerial vehicles (UAVs), artillery, paratroopers, helicopter flights, which are displayed
simultaneously on one monitor (the so-called "operating dashboard"), as shown in Fig. 1. The described
approach is interesting because it focuses on ArcGIS software (developer - ESRI, USA), which is
recommended for implementation in the Armed Forces of Ukraine. However, at this stage, the described
developments have not passed practical testing in military structures. In addition, ESRI's decisions focus
only on US government data sources and, as a result, use only relevant specialised data formats and
structures and operate within the United States.
An example of another approach to solving this problem is the system My Weather Impacts Decision
Aid (developer - MyWIDA, USA) provides a complete analysis of the impact of HMC on the actions
of troops and individual weapons systems [5]. This sophisticated expert system operates based on a set
of rules approved by the standards for the Army, Air Force (Air Force), and the US Navy.
MyWIDA automatically accepts multi-day weather forecasts that are compared to constraints
(rules). And it determines the favourable, borderline and adverse effects of the weather in the form of
charts superimposed on the background map and in the format of the weather effect matrix (weather
effects) (WEM) on conducting the operation as a whole, its components, the process of weapons
systems and the impact on other equipment.
Figure 1: Electronic dashboard with expert assessment of military aspects of the weather in the area
of Zhulyany airport - p. Vyshneve
It is also envisaged to obtain a textual reference to justify the decisions of the military administration
(OVU). The primary standard that defines the assessment of weather effects by developers is the Army
Field Manual (FM) 34-81-1 [6]. Weather effects are classified into three levels according to the
percentage of suitability (percentage of residual efficiency of personnel, equipment or weapons systems
that experience degradation (such as reducing their effectiveness) weather effect [6, 7]) (Table 2).
Table 2
Percentage of degradation for three impact indicators
Impact Criterion
Green (Favorable) Decrease by less than 25−30% (normative efficiency 70−75% and higher)
Amber Decrease from 25−30% to 70−75% (normative efficiency from 70−75% to
(Borderline) 25−30%)
Red (Adverse) Decrease by 70−75% or more (regulatory efficiency 25−30% or less)
The assessment takes place both in friendly and enemy forces. Based on this assessment, the
formulation of the presence or absence of a tactical advantage of a combat party in specific
meteorological conditions of hostilities is done. This assessment validity of is provided by an extensive
database of rules (over 15,000), which describe the main military effects of the weather [7].
The system built on the model described above is a separate (autonomous) element of the military
information environment. In our opinion, it has excessive complexity for direct implementation in
automated control of troops (forces). The system involves unique data sources - from specialised
services at the national level of CIF to autonomous computerised means of collecting meteorological
data, such as the car platform IMETS-Heavy. Also, in the MyWIDA documentation, we did not focus
on integration into other information systems, including professionally built GIS platforms.
The developer of the MyWIDA service also announces the development of an Android version of
the weather effects application for use in the tactical chain of command of individual commander [2,
10]. A feature of this application is the generation of personal recommendations to the commander to
establish the value of the comfort index for different values of temperature and humidity. Other criteria
allow you to adjust the time of personnel exposure to extreme cold or hot areas, parameters that
determine the efficiency of equipment etc. In general, as a result of analysis of sources, we find that the
methods of taking into account the weather effects on troops' actions are constantly evolving. In our
opinion, the priority in this issue is to find as many weather data sources as possible, including local
resources [8], to confirm the impact of hydro-meteorological conditions on the combat capabilities of
certain types of troops use of their weapons.
4. Research methods
General scientific research methods were used to assess hydro-meteorological (climatic) conditions:
1. An analysis is the determination of indicators of HMC influence on the capabilities of troops
(forces) and the use of weapons;
2. Synthesis is combining individual hydro-meteorological quantities (phenomena) into the HMC
system and determining their cumulative impact on the combat capabilities of troops (forces)
and the use of weapons;
3. The systemic approach is to substantiate the conclusions (proposals) on the implementation of
troops tasks, taking into account the influence of the HMC.
5. Experiments, results and discussion
According to [11], Hydro-meteorological support (HMS) by the Hydro-meteorological Service of
the Ukrainian Armed Forces is organised and coordinated by the Hydro-meteorological Centre of the
Armed Forces of Ukraine, hydro-meteorological (meteorological) services (subdivisions) of the Armed
Forces of Ukraine and operational commands providing interaction with the Ukrainian Hydro-
meteorological Centre, the state enterprise "Ukrainian Aviation Meteorological Centre" about the
Ukrainian Aviation Meteorological Centre functions on hydro-meteorological support of power
structures. The following special-purpose forecasts for the organisation of HMS are developed:
Aviation forecasts, for meteorological support of take-off, landing, flights in areas, flights on
routes;
Forecasts for the assessment of radiation and chemical (biological) conditions, which contain a
description of the expected parameters of wind and temperature near the earth's surface and at
altitudes, the state of clouds, the nature of precipitation;
Providing parachute jumps, landings (dropping loads), containing data on the expected speed
and direction of the wind in the layer from the ground to the height of parachute jumps,
characteristics of visibility, cloudiness, precipitation and temperature;
Forecasts for take-off, landing and flight on the route for uncrewed aerial vehicles;
Storm warnings about dangerous and natural hydro-meteorological phenomena;
Long-term (up to 3 days) and short-term (up to 36 hours) weather forecasts (hydrological and
aero-climatic information on request about the combat area and other recommendations to
commanders at all levels to ensure the safety of units, preservation of equipment, weapons,
personnel from the effects of dangerous meteorological, geophysical and hydrological
phenomena, the most effective use of firearms. They, in turn, make decisions to make the most
of the weather or minimise the damage from weather impact.
Hydro-meteorological information is structured in the following areas [12, 24]:
Meteorological elements,
Meteorological phenomena and dangerous meteorological phenomena,
Actual and predicted for different periods.
The most common atmospheric phenomena that affect the use of troops and weapons are:
Precipitation: mist, rain, snow, snow grains, ice pellets, ice needles, hail, snow pellets;
Phenomena that impair visibility due to the presence of water vapour in the air: fog, haze;
Phenomena that impair visibility due to the predominance of solid particles in the air: sand, dust
(precipitated over a large area), fog, smoke, volcanic ash;
Other phenomena are dust or sand whirlwinds, squalls, tornadoes, dust storms, sandstorms,
hurricanes, snowdrifts, snowstorms, dew, hoarfrost, ice, lightning, solar radiation, floods and
storm surges, etc.
Hazardous hydro-meteorological phenomena are squalls; tornadoes; hurricanes; floods that threaten
flood areas; mountain avalanches, earthquakes; volcanic eruptions; forest (steppe) fires; smoky air etc.
The primary data sources are meteorological (synoptic) and aero-logical stations, meteorological
satellites, meteorological radars, various automated and experimental observation systems
(observations from aircraft, buoys), and others. (Fig. 2) [14].
Figure 2: Systems and methods of measurement of hydro-meteorological (climatic) observations
It is necessary to develop basic software and hardware that will functionally provide practical
solutions to automate the collection, storage, processing and presentation of relevant operational
information to ensure high-quality hydro-meteorological planning and operation of units and
subdivisions of the Ukrainian Armed Forces and their weapons:
Actual and expected changes,
The state of the environment,
Warnings about dangerous and natural hydro-meteorological phenomena in the troops interests.
Its main task will be to collect from various services geodata (sources, communication channels)
reference materials (data) on the hydro-meteorological situation in different battlefield areas and assess
its impact on the capabilities of troops and the use of weapons.
We offer the use of the website windy.com as a prototype of the meteorological service, which
allows you to get the following meteorological data in any area: precipitation, air temperature, humidity,
wind strength and direction, etc., both on the earth's surface and at different heights above it. You can
also generate a weather forecast for the next ten days. All these data are displayed on an electronic map
of the area, presented in graphs (diagrams) and numerical parameters. As an element of geo-information
analysis technologies, the site provides a service for creating profiles of electronic routes on the terrain
using the calculation of the duration of movement on foot or by car and displaying the forecast of
weather conditions at each point of the road.
The formation of a web address for requesting data on the site is carried out according to the pattern:
https://www.windy.com/ [planning type] + [method of movement] + [list of geographical coordinates
of route points]. For example, Lutsk - Gorokhiv - Lviv - Yavoriv:
https://www.windy.com/distance/car/50.68,25.35;50.45,24.74;50.10,24.61;49.96,24.58;49.81,24.09;4
9.92,23.36?49,694.23,538.8. Placing this address in a web browser leads to the visualisation of the route
on an electronic map, building its profile and hourly display of weather conditions online (Fig. 3).
Figure 3: Windy.com meteorological service
This approach, in our opinion, can be a prototype of service for the rapid supply of meteorological
information to the authorities when deciding to conduct hostilities. Therefore, it is proposed to include
a geodata service to assess the impact of hydro-meteorological conditions in the structure of the geo-
information subsystem of the battlefield management system for units and subdivisions of the Armed
Forces of Ukraine, as shown in Fig. 4. The general-purpose geo-information subsystem in the BMS will
be used for input, processing, and analysis of data that have a spatial component and automate the
development of combat graphics and electronic maps by tracking all changes in the situation of their
operational display. This subsystem is aimed at comprehensive support of decision-making processes
for combat operations, their planning, and the management of the use of troops and weapons [28, 29].
Software and mathematical support of the geographic information subsystem should able to:
Adapt to changes in functional modules (task management;
Data formation of the evaluation area;
Data formation of the weather log of the evaluation area;
Evaluation calculations;
The ability to provide a common language for the users,
Present the results in a form that would contribute to a deeper understanding of the results and
recommendations.
That is, various data streams (prognostic; climatic; recommendations for decision-making; metadata,
etc.) about changes in weather and natural phenomena must be transmitted using a high-level protocol
in files (packages) of a clearly defined format and submitted to the workstations of designated officials.
This will allow avoiding mistakes in assessing its impact on the combat capabilities of units and the
effectiveness of weapons, forces and means for the senior commander, interacting units and the enemy
troops, as well as optimise tactical planning, minimise losses and losses, due to the efficiency and
priority of decisions made [21, 22, 23, 30-32].
Figure 4: Geo-data service for assessment of terrain and weather conditions in the structure of the
geographic information subsystem of the BM of units and subdivisions of the Armed Forces of Ukraine
The development of the order to support the decision-making on the estimation of HMC, after
reception and the analysis of the information by officials, should carry out in several stages (Fig. 5):
1. The choice of the combat area is the formation of time intervals for the receipt of hydro-
meteorological information for the period of execution of tasks by units.
2. The definition of evaluation criteria and indicators. The actual and expected (projected) HMC
impact on the use of weapons and units in the combat area is assessed using impact indicators.
They can be classified into different groups to establish the eligibility criterion. According to
the conditions are considered appropriate if all partial indicators belong to the adequacy region.
I.e. they do not exceed the allowable values [20]. This assessment serves as a basis for choosing
the best alternative.
𝐾𝑝 : (∀)(𝑦𝑖𝑓𝑎𝑐𝑡 ∈ 𝛿|𝛿𝑖 → 𝑦𝑖𝑎𝑙𝑙 , 𝑖 ∈ 〈𝑃 〉), (1)
where: 𝑦𝑖𝑓𝑎𝑐𝑡 is the actual value of the elements and phenomena of the HMC in the combat area;
𝑦𝑖𝑎𝑙𝑙 is the allowable value of the elements and phenomena of the HMC in the combat area;
𝑃 is the effectiveness of using weapons and units in actual or projected HMC in the combat
area.
Because of the impact of HMC on the combat capabilities of divisions and subdivisions, the use of
their weapons is versatile and multi-faceted; its degree depends on the actual values of hydro-
meteorological elements and phenomena. Tables 3-5 show indicators and levels of assessment of HMC
impact on manoeuvrability (combat) capabilities for units of the Armed Forces of Ukraine, as well as
the use of their weapons [25], the suitability criteria of which are assessed as "favourable", "transitional
(threshold) "," adverse".

3. Formation of a set of indicators and assessment of the impact of HMC. The construction of a
group of HMC assessment indicators consists of the automatic selection of HMC assessment
indicators from the database array for a particular combat area. Each HMC indicator contains
characteristic values (maximum, minimum, average) that characterise their impact on units'
combat capabilities and the use of weapons and military equipment [12, 16, 18-19]. Partial
assessments for each element of dangerous meteorological phenomena affecting them are also
determined by establishing deviations in the actual values of indicators from normative ones –
separately for each type of combat capabilities of units and military equipment in their
composition. The integrated assessment is determined by the rule of most significant negative
impact (worst partial review) on the combat capabilities of brigade units and the use of weapons
and military equipment, namely, if:
All partial assessments are favourable, and then the integral evaluation will also be
complimentary;
At least one element (phenomenon) receives an assessment of "adverse", and then the
integral evaluation will also be adverse;
Partial assessments are favourable and transitional or only transitional ones, then the critical
evaluation will be "transitional".
4. Assessment of decisions. The final document sections with conclusions on the evaluation of the
situation are formed as a result, based on the integral assessments of the HMC. For each variant
of the scenario, a typical set of protective actions and measures to ensure hydro-meteorological
safety in troops' activities and the operation of WME in the area of combat operations is
developed. Also, recommendations for choosing the optimal plan for the functioning of units
and units of the Armed Forces of Ukraine, considering the entire range of possible weather
conditions, is developed.
6. Conclusions
1. The analysis of the requirements of NATO standards for the study of HMC and geo-information
and Internet technologies for obtaining and processing meteorological data was carried out.
Some of these services are focused on compliance with NATO military standards (the United
States).
2. The structure of the geo-information subsystem of the BMS for units of the Armed Forces of
Ukraine, which contains a unique location service for assessing the impact of hydro-
meteorological conditions on the use of weapons and combat capabilities of troops (forces)
according to the criteria of suitability, is proposed.
3. The methodology for assessing the impact of hydro-meteorological conditions on the training
and conduct of combat operations of troops for the geo-information subsystem of the automated
battlefield management system is proposed. Unlike the existing ones, this system considers the
assessment of the impact of the HMC on the use of weapons and combat capabilities of troops
using special software (weather service), which makes it possible to quickly supply hydro-
meteorological information to commandment bodies deciding on combat operations.
4. Within the framework of the recommendation and prospects for further research, it is worth
noting that this material can serve as the basis for solving optimisation problems of information
usage in decision support systems to ensure the hydro-meteorological safety of troops.
