How extreme is the weather in Kiev, Ukraine, which has become a world of ice and snow after snow?

Kiev, Ukraine, after the heavy snow, the streets of Kiev are covered with snow. After it snowed in Kiev, Ukraine, it became a world of ice and snow. How extreme is the weather in this country? The following is a detailed introduction:

1.Since February, Ukraine and other places have experienced extremely cold weather. The lowest temperature in Ukraine and other places is MINUS 40℃, and the snow in mountainous areas is stable, independent of winter temperature and not concentrated in the coldest month. However, the extremely unstable duration of low-lying snow is short, and its survival is highly dependent on negative temperature. Snow is concentrated in the coldest month, which is very sensitive to temperature changes and easy to heat up. Secondly, the snowfall in winter in China is mainly caused by the infiltration of cold air from Siberia. Water vapor comes from the warm and humid air flow in the south or southeast, and the air humidity in this area also has a great influence on snowfall. Therefore, climate warming will lead to the strengthening of air flow exchange and water circulation between north and south, and increase snowfall in the Yangtze River basin. Therefore, the regional differences between arid areas with less snow and humid areas with more snow are further aggravated. In addition, low temperature has an opposite effect on the formation of snow and snow. Extremely low negative temperature is not conducive to the formation of snow, but it is beneficial to the maintenance of snow. Therefore, the snowfall season in China is concentrated in early winter and early spring, and the glaciation area of ultra-high mountains is even concentrated in summer. On the contrary, the snowfall decreases in the coldest month, and the decrease in colder areas is more significant. Therefore, warming may lead to an increase in snowfall in the northernmost and mountainous areas of China.

Second, the frequent occurrence of extreme weather is due to the increasing emission of greenhouse gases, which leads to global warming becoming a major trend. Climate warming leads to atmospheric instability. Jiangsu is located in a complex warm temperate climate zone, which will lead to more and more severe convective weather such as rainstorm, typhoon, hail and tornado, and more and more extreme weather phenomena, making weather forecasting more and more difficult. Influenced by the warm and humid air current in the Atlantic Ocean, most areas have temperate continental climate, while southern Crimea has subtropical climate. 1 the annual average temperature is -7.4℃, and the July average temperature is 19.6℃. The annual precipitation is 300mm in the southeast and 600-700mm in the northwest, mostly in June and July. Controlled by the continental air mass all year round, precipitation increases from south to north, and natural vegetation changes from south to north from temperate desert and temperate grassland to coniferous forest in sub-frigid zone.

3. In the coldest month of winter in Ukraine (65438+1October), the average temperature in the north and east is MINUS 7 degrees, and the south bank of Crimea is MINUS 2 to 4 degrees. In summer, the highest temperature in most parts of the country is 36 and 39 degrees, and the lowest temperature in winter is about MINUS 40 degrees in the east and MINUS 30 degrees in the south. The annual average precipitation gradually decreases from the west and northwest to the southeast and south. The maximum annual precipitation in Carpathian area is 2000mm, in Polynesia area is 970mm, and in southern area is 500mm, but the minimum annual precipitation in the above areas is 800mm, 300mm and100mm respectively. The dry weather in Ukraine occurs once every 2-3 years on average. Dry weather poses a constant threat to agriculture.
