В статье приведен анализ метеорологической информации по средней температуре воздуха за вегетационный период на территории Крымского полуострова. Рассчитано среднее многолетнее значение в точках расположения метеостанций с длинным рядом метеонаблюдений на территории Крымского полуострова. При расчетах использовали многолетние данные за 30 лет по 17 метеостанциям Крымского полуострова. Для моделирования пространственного распределения величины средней температуры воздуха на первом этапе также была выбрана глобальная климатическая модель WorldClim 2.0. На её основе рассчитаны величины исследуемого показателя для опорных точек. Произведена корректировка данных модели WorldClim 2.0 путём прибавления к результатам расчёта поправки 0,99, что несколько повысило точность моделирования. Составлена также линейная многофакторная модель, учитывающая географическую широту местности и абсолютную высоту над уровнем моря. Установлено, что в зависимости от географического положения метеостанции значения средних многолетних температур воздуха составляют от 17,9 °С (Белогорск) до 20,0 °С (Феодосия, Ялта). Проанализированы при помощи технологий геоинформационного моделирования закономерности пространственного варьирования величины средней температуры. В результате проведенного анализа были получены модели, описывающие данные закономерности. С помощью полученных моделей, разработана цифровая крупномасштабная картографическая модель пространственного распределения величины средней температуры воздуха, на основе которой на территории Крымского полуострова выделено 4 зоны. Разработанная модель, в сочетании с современными геоинформационными технологиями дает возможность автоматизировать анализ степени пригодности территории для возделывания винограда. The article provides the analysis of meteorological information of the mean air temperature for the growing season on the territory of the Crimean Peninsula. The long-term mean value in the points of weather station locations with a long series of weather observations on the territory of the Crimean Peninsula was calculated. For calculations we used the long-term data for 30 years on 17 weather stations of the Crimean Peninsula. To simulate the spatial distribution of the mean air temperature value at the first stage, the WorldClim 2.0 global climate model was also selected. The values of the studied parameter for reference points were calculated on its basis. The data of the WorldClim 2.0 model was adjusted by adding an error correction of 0.99 to the results of calculation, which slightly increased the modeling accuracy. A linear multivariate model was also compiled, taking into account the geographical latitude of the terrain and the absolute height above sea level. It was established that, depending on the geographical location of the weather station, the values of long-term mean air temperatures range from 17.9 ° C (Belogorsk) to 20.0 ° C (Feodosia, Yalta). The patterns of spatial variation of the mean temperature were analyzed using the technologies of geoinformation modeling. Models describing these patterns were obtained as a result of the analysis. Using the models received, a digital large-scale cartographic model of the spatial distribution of the mean air temperature was developed. On its basis 4 zones on the territory of the Crimean Peninsula were allocated. The developed model, in combination with modern geoinformation technologies, makes it possible to automate the analysis of fitness degree of the territory for grapes cultivating.

Оригинальное исследование по изучению распределения среднемесячной температуры в августе на территории Республики Крым проведено сотрудниками сектора агроэкологии. Неоднократно доказывалось, что температура воздуха оказывает большое влияние на рост, развитие и качественные показатели виноградного растения. Особое влияние на качество урожая оказывает температура воздуха в августе, так как именно в этот период наблюдается лучшая ассимиляция углерода листьями и соответственно происходит накопление сахаров и уменьшение кислотности. В качестве материалов были использованы электронная модель рельефа SRTM-3 территории Крымского полуострова и многолетние данные метеонаблюдений по 17 метеостанциям Крыма и Севастополя за 1985-2019 гг. Для моделирования пространственного распределения величины среднемесячной температуры воздуха в августе были использованы три математические модели, в том числе одна авторская. На основании полученных результатов была построена цифровая крупномасштабная карта пространственного распределения среднемесячной температуры воздуха в августе на территории Крымского полуострова и выделено 5 зон по среднемесячной температуре в августе. Использование данных моделей в ГИС (геоинформационная система) дает возможность автоматизировать анализ степени пригодности территории для возделывания винограда. The original study on the distribution of the average monthly temperature in August on the territory of the Republic of Crimea was carried out by staff scientists of the Agroecology Sector. It has been proven many times that air temperature has a great influence on the growth, development and quality indicators of a grape plant. Air temperature in August has a special effect on a crop quality, since it is during this very period the best assimilation of carbon by leaves is observed, resulting in sugar accumulation and acidity decrease. The materials used were the SRTM-3 digital terrain model of the Crimean Peninsula and long-term average annual data of meteorological observations in 17 meteorological stations of Crimea and Sevastopol for the period of 1985-2019. To model spatial distribution of the average monthly air temperature in August, three mathematical models, including one authorial, were used. Digital large-scale map of spatial distribution of the average monthly air temperature in August on the territory of the Crimean Peninsula was compiled basing on the results obtained. Five zones were identified according to the average monthly temperature in August. Using of these models in GIS (geoinformation system) makes it possible to computerize the analysis of applicability of the territory for grape cultivation.

The authors have studies the regularities of the mean annual runoff of the rivers at the Crimean Mountains Northwestern slopes on the basis of the hydrological stations’ data. For all station, including the closed ones, that data were unified against a single many-year uniform period for which we calculated mean annual water flows and runoff modules. It has been stated that mean annual runoff modules, in contrast with the most of small rivers of Russia are decreasing with the increase of catchment areas and the river hydrographic length, and this is associated with the evaporation effects. In addition, we have found diminishing dependence of mean many-year runoff modules on remoteness from the sea and increasing dependence on the catchment average height.We have stated that it were these above factors that decisively effect on the Kacha, Belbek, and Chernaya rivers runoff formation, particularly in the downstream were the watercourses face anthropogenic impact. These rivers have catchment areas exceeding 250 km2. The anthropogenic factors impact upon formation of the mean annual runoff is not so significant in comparison with that for rivers with lesser catchment areas. However, any hydrological station data supporting this fact are not available.

The composition of 12 populations of Adalia bipunctata L. of the Crimean peninsula was studied. The proportion of black individuals varies from 4.8% to 64.6%. Comparison of the composition of color forms with climatic parameters of habitats showed that the proportion of black individuals in the population positively correlates with the value of moisture during the period of reproduction of beetles (May-July) and negatively correlates with the mean temperatures of these months.

The article presents the results of spatial and temporal dynamics research of the air temperature fields on the territory of the Crimean Peninsula due to the change of circulation epochs and periods of the Northern Hemisphere. Average multiannual maps of air temperature on the Crimean Peninsula for each circulating epoch and period were obtained, as well as maps of temperature fields dynamics at their change. Based on the obtained analysis of the maps it was found out that change in air temperature occurred not synchronously, but had its own characteristics in different regions of the Crimean Peninsula, which is explained by the influence of local factors. Zones characterized by constant maximum air temperatures in all considered periods have been recorded. It was found that during the instrumental observations on the Crimean Peninsula the warming occurred by 1 °C. This warming was occurring during the last circulation period.

Climate change in Crimea is characterized by spatial heterogeneity in the displacement of air temperature fields, due to the influence of regional and local factors. There are currently no works devoted to the study of the reaction of regional ecosystems to changes in air temperature in Crimea. Based on open databases of reanalysis, geoinformation modeling the results of studies of the dynamics of air temperature in the main types of ecosystems of the Mountain Crimea under conditions of climate change are presented. For each circulation epoch and period of the Northern Hemisphere, maps of average annual temperatures were obtained along the landscape contours of the Crimean Peninsula. A map of the standard deviation of temperature within the landscape contours was made. For key areas, the mean annual air temperature, standard deviation, and factorial entropy were calculated. The main regularities of air temperature dynamics in the main types of Mountain Crimea ecosystems with the change of circulation epochs and periods of the Northern Hemisphere are revealed. Based on the analysis of the dynamics of the standard deviation and factor entropy, the role of changes in air temperature in the formation of strategies for the development or stabilization of the main types of regional ecosystems in Mountain Crimea is shown.
