oa Mapping of climate change on the teritory of Ukraine

The study of a climate change in Ukraine in the twentieth century by means of geographic information mapping aims to draw attention to the problem of the climate change, both scientists and the general public and decision-makers in the field of the climate policy. As a result of processing and presenting data from the scientific organization NCAR GIS Climate Change Scenarios, a retrospective series of analytical maps was created. In the ArcGIS program three series of maps (a total of 30 maps) of changes in the average annual climate indicators of Ukraine in the twentieth century in steps of 10 years were created. Based on the Keppen’s climate classification, a series of maps of climate zones of Ukraine, which reflect the change of climate types in the twentieth century in steps of 20 years, was built. The developed analytical and synthetic cartographic works fully characterize the climate changes that Ukraine has undergone during the twentieth century. For the territory of Ukraine according to the Keppen’s classification, by removing the critical types, the main types of climate are determined - B, C, D. After determining the general type of climate, subtypes are distinguished based on the amount and nature of precipitation. The third order of the classification concerns the features of the temperature regime. The research results indicate a change in Ukraine’s climate before warming, a gradual increase in aridity in the southern regions and a significant increase in the temperature of the coldest month. There is a high probability that the continentality of the climate will decrease. In the worst case, some southern regions of the country may be prone to desertification.
