Temperature distribution in winter and summer in China

(1) China has a vast territory, spanning multiple temperature zones and dry and wet zones, with complex terrain and great disparity in height, which increases the complex diversity of China's climate. In winter, the temperature difference between north and south is large, and the south is warm, but the farther north, the lower the temperature. Summer is generally high from north to south.

(2) China is located in the northern hemisphere, with a north-south span of nearly 50 latitudes. In winter, the sun shines directly in the southern hemisphere. For the northern hemisphere, the higher the latitude, the lower the midday sun altitude angle. In northern China, the sun's height angle at noon is lower than that in the south, and the daytime is shorter, so less light and heat can be obtained from the sun. In addition, the northern part of China is close to the source of winter wind, which intensifies the cold in northern China. When winter winds pass through many mountains and reach the south, in Hainan Province, the average temperature in winter is around 20℃, and the climate is warm and hot.

(3) From the map, Qinling is an east-west mountain range in China, and the Qinling-Huaihe line is basically consistent with the 0℃ isotherm of the monthly average temperature of 65438+ 10.

So the answer is: (1) In winter, the temperature difference between the north and the south is large, the south is warm, and the farther north it is, the lower the temperature is; (2)C； (3) things; 0.
