The article analyzes the changes that took place in the higher school of Ukraine over the past 25 years in terms of their impact on the system of training specialists with higher education in hydrometeorological specialties. Three stages of the higher education reforms and their impact on the training of personnel for the hydrometeorological service of Ukraine are singled out. The priority measures are proposed, which will enable the operational departments of the hydrometeorological service to be provided by specialists who meet the modern requirements of
the World Meteorological Organization.
In the paper the review of the meteorological research in Ukraine at the end of the 20-th century – the beginning of the 21-th century was made. Researches in the field of meteorology are performed mainly by the Ukrainian Hydrometeorological Institute of the State Service of Emergencies of Ukraine and National Academy of Sciences of Ukraine, Odessa State Environmental University (OSENU) and Taras Shevchenko National University of Kyiv
(TSNUK).
The studies of UkrHMI scientific schools headed by well-known scientists in the field of meteorology were devoted to the development of new theories, methods, models in the field of the weather forecasting and dangerous situations in Ukraine, radiation balance, agrometeorology, climate researches in the Ukraine, numerical modeling of cloud physics and active effects on clouds, numerical methods in analysis and forecast of natural and technogenic processes in the atmosphere.
In OSENU, where two scientific schools are established, the scientists study the formation of severe weather and its forecast, diagnose and forecast mesoscale atmospheric circulations, identify nonlinear interaction between the main global structures, detect the features of circulation processes in high latitudes of the southern hemisphere, conduct systematic studies in the field of numerical modelling of physics and dynamics of atmospheric processes with the Enviro-HIRLAM and HARMONIE models.
Scientists of TSNUK study changes in the total column ozone amount in the atmosphere of Antarctic Region and the mid-latitudes of Northern Hemisphere. The work on analyzing the state of climatic parameters and changing the current climate of Ukraine is being carried out at the KNU.
The article analyzes the current state of climatology in Ukraine, the problems and prospects for its development. It is shown that although Ukraine the signed the Paris Agreement and this fact is very important for the development of modern climatology, Ukraine’s state policy on climate change has a fragmented character and is currently considered exclusively as a component of environmental policy. The lack of systems approach to the problem of climate change makes it impossible to make management decisions on actions for climate change adaptation and mitigation at the scale of whole economy of Ukraine. At the same time, the new tasks, which are due to the expediency of ratification by Ukraine of the Paris Agreement and the further implementation of its provisions,
require the development of a coherent and consistent state policy on climate change.
The main scientific directions of the development of climate services in Ukraine are presented in accordance with the Global Framework for Climate Services. The main tasks for each element of climate services – a platform for interaction with users, an information system for climate services, observing and monitoring systems, capacity development – are outlined for Ukraine, problems are indicated and prospective directions of development are proposed.
Study of the El Niño-La Niña is a major challenge for the scientific community. In addition to the impact on weather and climate in different regions of the Earth, this phenomenon is associated with the socio-economic impact for many countries. The task of such a large-scale phenomenon prognosis is associated with considerable difficulties, one of the main problems is the infrequency of its occurrence and changes in the characteristics between the events. Therefore, a comprehensive study of its urgent task for the international scientific community.
This paper presents the results of a study of the statistical structure of the fields of geopotential heights of 850 hPa pressure level in the western sector of the Southern hemisphere. The study was conducted using a component analysis. Decomposition fields of principal components in different scales are shown. Filtered field anomalies suggest tendencies of formation of the zonal Walker’ cells, characteristic for the warm period of El Niño, La Niña, when the structure of the Walker’ cell is less pronounced. Tendencies offset to the east of the Pacific high in the Southern Hemisphere to split it into two parts, as can be seen from the fields of geopotential height anomalies. The zonal circulation Walker’ cell in the warm and cold phases of ENSO is clearly appeared in the fields of geopotential heights, when is highlight the part caused by the second principal components.
The article describes the methods of making short-term weather forecasts and storm warnings in the Hydrometeorological Department of the Republic of Belarus using different sources of information (monitoring of synoptic situation, use of various satellite information, radar data etc.). It presents information about an observation network operating in the country (upper-air and surface observations). It also indicates the aims and results of the BALTRAD project resulting in creation of a modern, real-time meteorological radar network which connects the Republic of Belarus and the countries of Baltic region.
The article contains short information about use of numerical weather forecasting models, in particular, the mesoscale model WRF-ARW which runs on the cluster system available in the Hydrometeorological Department. The GFS model data (0.25° increment) are used as a source of input data for modelling. Once launched the WRF model generates a forecast with advance time of 48 hours while time resolution of output data is equal to 1 hour. Calculation is performed as per “nested grids” with two domains having spatial resolution of 15 and 3 km which provides detailed information and enables making forecasts of local phenomena.
Special attention is paid to products of the department of meteorological forecasts, especially to the hydrometeorological bulletin for the President with its structure being specified. The risk gradations are shown and characterized with allocation of colour codes based thereon in order to introduce respective forecast meteorological products: the weather is not dangerous (“green”); the weather is potentially dangerous (“yellow”); the weather is dangerous (“orange”); the weather is very dangerous (“red”).
The article specifies current problems arising during conduction of hydrometeorological activities and the ways they can be solved as indicated in the Strategy for Development of Hydrometeorological and Environmental Monitoring Activities in the Republic of Belarus until 2030.
In the article you can read about the methods used for forecasting convective processes by means of output products of numerical models with various spatial resolution. It presents the methods for forecasting convective phenomena applied in the Hydrometeorological Centre of the Republic of Belarus. The state of the atmosphere affected by intensive convection over the territory of the Republic of Belarus on July 13, 2016 is analyzed. The categorial evaluation of the thunderstorm forecasting methods by G.D. Reshetov and I.A. Slavin is specified with the respective results presented. The article analyzes the forecast of convective phenomena conducted with the help of the non-hydrostatic regional model WRF-ARW.
Use of convective instability indices and calculation methods can facilitate convective phenomena forecasting. The advantage of their use consists in possibility of their application within the areas not covered by aerological sounding. However, selection of indicators of instability and methods of thunderstorm and other dangerous phenomena forecasting depends on features of an area under study and this requires further research.
To ensure more accurate convective phenomena forecasting it is necessary to consider radar, satellite and aerological observations when conducting numerical model calculations. The results of the research showed that convective phenomena forecasting requires use of models with a high spatial resolution.
Amid political and, consequently, economic and environmental problems engulfing Ukraine one of the today’s challenges consists in studying the possibility of use of natural potential of renewable energy sources. Resources of solar radiation have no negative impact on the natural environment and human activity. Therefore development of helioenergetics and at the same time climatic substantiation of solar power plants use research become more and more important. The purpose of this article is to evaluate of the solar radiation potential opportunities for implementation of technical innovations within the territory of Ukraine and to identify prospects of helioenergetics development. Special indicators of solar radiation components for 1961-1990 s are showed. Using the method of mathematical statistics we defined a value of direct solar radiation contribution forming a part of the total radiation for the warm season (April-September). During the period of 1991-2015 an increase of solar radiation climatic resources relative to climatological standard norm of 1961-1990 was revealed. Over 2001-2015 annual direct and total solar radiation values increased even more in comparison to 1991-2000. Increase of duration of sunshine was also observed. Due to changes of radiation characteristics special indicators of solar
for 1991-2015 were specified. The prospects of solar radiation use in helioenergetics proved their feasibility in Crimea, steppe zone, eastern part of forest-steppe zone and even in some parts of Polissya. Comparing to previous years, in terms of sunshine duration over 2000 hours per annum the territory expanded northward. Restrictions on innovations implementation apply to western forest-steppe zone and mountainous areas of Ukrainian Carpathians. Increase of solar radiation regime components determining the feasibility of solar power energy resources form the basis for their countrywide use.
The article in question describes the history of development of agrometeorological service activities for agricultural production from the days of Mikhail Vasilyevich Lomonosov to the present. It is pointed out that the agrometeorological service experienced especially rapid development in the second half of the twentieth century. Establishment of the Department of Agricultural Meteorology in 1953 at the Ukrainian Research Hydrometeorological Institute stimulated development of agrometeorological research in Ukraine. Three stages can be distinguished in researches of this department on the influence of weather conditions on yield formation. At the first stage (1953 – 1963) generalization and systematization of the materials for study into agrohydrological soil properties were performed. At the second stage (1963 – 1973) a working hypothesis on the scheme for taking account of the influence of weather conditions on the vegetative mass increase was formulated, and a correlation analysis of crop productivity with hydrometeorological elements was carried out. A huge amount of work on research into the regime of photosynthetically active radiation and crop productivity as well as into the phytoclimate of the sown areas has been performed. The third stage (since 1974) is the stage of formation of a basic model for crop productivity and development of methods for forecasting productivity.
The agrometeorological service activities for agricultural production at every level is imple-mented in accordance with the approved annual plans for hydrometeorological activity of organizations. A basis for the agrometeorological provision is formed by the materials of meteorological and agrometeorological observations which are conducted at 163 meteorological stations throughout the country.
The Hydrometeorological Service of Ukraine represents the country in the World Meteorological Organization (WMO), an agency of the United Nations Organization (UNO). Leading agrometeorology experts take part in the activity of WMO Commission for Agricultural Meteorology (CAgM).
Relying on the scientifically substantiated methods of agrometeorological assessment, forecasts and recommendations, the Ukrainian Hydrometeorological Center and the regional centres for Hydrometeorology provide all the agricultural industries of the Agroindustrial complex with relevant information.
Introduction. The existing agroclimatic handbooks in Kazakhstan are outdated in informational and
technological relation. Therefore it is necessary to conduct reassessment of agroclimatic resources.
Purpose. The agroclimatic zoning of the territory of northern Kazakhstan in terms of heat supply and moisture
content.
Methods. Data of meteorological stations over 1981-2014 were used. Methods of statistic and climatologic
processing of data were applied. Agro-climatic maps were developed using the ArcGIS 10.1 software.
Results. Analysis of spatial distribution of values of moisture coefficient K and sums of active air temperatures
above 10оC provided an opportunity to single out 6 agroclimatic zones of plain territory of Kazakhstan. Zones from 3 to 6 are subdivided into two types in terms of thermal conditions. There are 3 agroclimatic zones singled out within the territory of North Kazakhstan Region, 4 zones – in Kostanai region, 4 zones – in Akmola region, 2 zones – in Pavlodar region. Distribution of drought characteristics, hot dry winds and climatic terms for beginning of spring field works within Akmola region’s agroclimatic zones was given as an example for systematization of spatial distribution of respective values. The first zone with moderately humid and moderately warm climate has severe droughts with recurrence of 2%, hot winds of moderate intensity are observed during 2-3 days, climatic terms for beginning of spring field works fall on 15th-19th of May. The fourth zone with moderately dry and warm climate has severe droughts with recurrence of 30-35%, hot winds of moderate intensity are observed during 20-25 days, climatic terms for beginning of spring field works fall on 5th-7th of May.
Conclusions. There are 3 agroclimatic zones singled out within the territory of North Kazakhstan Region, 4 zones – in Kostanai region, 4 zones – in Akmola region, 2 zones – in Pavlodar region.
