On the basis of the steadystate Gaussian dispersion model is created the model of meteorological potential of pollution of an atmosphere with the help of transformation of the factor is constructed to dilute pollution. The model is suitable for practical calculations of meteorological potential with the purpose of protection of atmospheric air from pollution. The model can be used as base for all-round studying climatic and meteorological conditions. Which conduct to dangerous levels of pollution of an atmosphere. Use of the longterm
climatic data will allow to investigate potential of pollution of an atmosphere in various geographical zones.
Method of mathematical modeling of radionuclide activity forming in the system “water – soil – plant – product” was described. Contamination quantitative assessment of total biomass, seeds and products of their processing on the South of Ukraine was received on the example of sunflower (Heliantus annus L.) agrophytocenosis
The testing of different methods of shortwave reflected solar radiation fluxes (RSRF) estimation on the top of atmosphere(TOA) using AVHRR data from NOAA satellites was carried out. It was shown that the Hucek and Jacobowitz method gives the best results. The relative error of RSFS estimation on TOA using this method is 0.12 and only for specific geographical zone this error is 0.16
Methodology for calculation of aggregate climate change index which taking into account abnormal events in the temperature and precipitation is described. The method is used for Europe. It is shown that greatest climate change during 1978-2006 years occurred in the Central Europe, Western and Central Mediterranean, and Pyrenees.
The evaluation of systematic error in the limited area model MM5v3.7 with different parameterization schemes for the atmospheric boundary layer, cumulus, radiation and microphysics is carried out in this work. Estimate is based on the comparison of model forecast variables versus reanalysis ERA40. Systematic error for major atmospheric prognostic variables is described in terms of diagnostics such as the lead-time evolution, spatial distribution, vertical profiles and spectra. Optimal sets of parameterizations schemes for different variables are proposed to use in numerical simulations.
The questions of changeability of extreme characteristics of heat and moisture in East Siberia are considered in work. Information for history period is analyzed. Conformities to the law of change of rows of values and events of climatic parameters are exposed. Repetitions of events are estimated.
Changes of agroclimatic conditions of cultivation of a winter wheat during the autumn-winter and springsummer period on different by scripts of change of a climate and their influence on photosynthetic productivity cultures are considered.
Quantitative interdependencies of indices for light air frost and ground frost in spring and autumn are established. A method of climatological information compression is applied and complex zoning of conditions of light frost risk is carried out by nine indices on a middle scale within the limits of the Odessa region. Probabilistic assessment of dates for spring and autumn light frosts of various intensity is made. Probability of damage by freezing to vine and apricot is determined.
Results of the long-term experimental researches of a hydrometeorological regime of fields executed by the author with vegetable cultures are stated. Laws of change of radiating and thermal balances in crops an eggplant, sweet pepper and tomatoes of various density, their influence on formation of a hydrometeorological regime and its change under influence of an irrigation are established.
Features of duration of a vegetative period and a period of active vegetation on the territory of Ukraine is examined on basis of statistical analysis of empirical data about stable transition dates over 50 С and 100 С over a period of time from 1960 to 2000 years
The results of numerical experiments on the evaluation of agrometeorological conditions impact on fitoftora development and its damaging influence on accumulationof biomass of potato plant separate organs and forming the productivity as a whole applying to the West Polesie conditions are presented A. N. Polevoy’s pattern modeling fitoftora origin and its damaging influence on potato productivity forming as a whole are in the basis of these numerical experiments.
In work numeral computation of offensive of phase is analysed «shoots» of spring barley in the Kiev region depending on the complex of agrometeorological factors. Computation of period sowing-shoots is based on decomposition of equalization of logistic curve in the row of Taylor’s series. Estimation of all necessary parameters of the offered model is produced. The analysis of comparison of actual and computation dates of phase is conducted «shoots».
The theoretical aspects of the use in estimate practice of formulas of reduction type are examined in the article.
To improve the water quality in the Odessa’s recreation beach zone the special variants of reconstruction of the
present wavebreaker are proposed. The results of numerical simulation of the wave parameters on the Odessa’s
beach zone under the different configurations of the shielding constructions are presented.
Observation data of temperature and salinity are used to calculate geostrophic current and to evaluate water
transport between Africa and Antarctic continental slope, 15-30 E.L. Mean geostrophic current schemes are
based on the use of calculation on a grid with the one-degree resolution for the south hemisphere summer
(January-March) during several years. These shemes show additionaly to episodic inputs of Agulhas eddies to
South Atlantic the presence of the permanent westward narrow branch of Agulhas Current intruded into
Benguela Current. Mean velocity in this branch is about 7-10 cm/s and average water transport is 20 Sv
(20·106 m3/s). Transport of Return Agulhas Current is about 50 Sv. Average general transport of water from
west to east Circumpolar Current is 170-175 Sv.
The results of statistical dependence between ground atmospheric pressure and temperature of water in zone of
the continental slope of a west part of Black sea on horizons 0, 5, 10, 15, 20, 25 meters are received and
analysed. It is shown, that ground atmospheric pressure essentially influences temperature of sea water on
horizons 0 – 10 meters
