What is the moral of the summer heat? The weather is hot, but it is not the hottest yet.

The summer heat is called "small heat", which means that although it can already feel the heat of the weather, it is not the hottest in a year, and it is only the beginning of a hot summer day. Monsoon climate is the main feature of China's climate. Monsoon climate is a mixture of continental climate and maritime climate. In summer, it is affected by warm and humid airflow from the ocean, and it is hot, humid and rainy. The high temperature in monsoon climate is basically the same as that in rainy period, and the rain and heat are in the same period, which is beneficial to crop growth. In the summer, the weather is hot and thunderstorms are frequent, which is the season when everything is crazy.

Although the light summer is not the hottest season in a year, it is followed by the hottest big summer. There is a saying among the people that "the light summer and the big summer will steam and cook", and the weather will become more and more sultry and humid, and the heat will be overwhelming, making people have nowhere to hide. When it comes to the light summer, it will begin to enter the dog days, and the earth will no longer have a cool breeze, and there will be a heat wave in the wind. During the light summer, it is already midsummer in southern China, and some places have also entered the season with the most thunderstorms, often accompanied by strong winds and heavy rains. Since the light summer, people are ready to meet the heat.

Flood

Summer drought

China's climate is "rainy and hot at the same time", but summer drought also occurs in some places. The summer drought generally lasts from mid-July to mid-August. At this time, the stationary front of Meiyu has moved to the middle and lower reaches of the Yellow River and the northeast in early July, and the middle and lower reaches of the Yangtze River are controlled by the "subtropical high", forming anti-cyclone weather, which is dominated by downdraft, with long sunshine, strong solar radiation, high temperature and strong evaporation. Crops grow fast, and the water demand of farmland is great. However, due to the single air mass, except for thunderstorms in some areas, there is no large rain area, and drought and hot summer weather generally occur, so it is called "summer drought". The summer drought mainly occurs in the Yangtze River valley in China and the south of the Yangtze River, especially in Hubei, Hunan, Jiangxi, Jiangsu, Anhui and other provinces. When the subtropical high in the western Pacific is controlled and there is little typhoon activity, it is prone to severe drought, and the precipitation is significantly less than the multi-year average.
