Rumor that it won't rain in summer

The proverb that it doesn't rain in summer is as follows:

There are signs that the weather is going to change. Insects, livestock and fish can all predict that there will be water and rain on the stones, water and sunshine on the grass, and mosquitoes are metaphorically speaking that it will rain tomorrow. Eat millet in summer, eat whole grains in summer, and have more scorpions at night. During the day, it rains cats and dogs, and the sound of rain calls, predicting fine weather. Five days without rain is a bit dry, ten days without rain is a bit drought, January without rain and smoke, bees never leave their nests, and it rains that day.

Butterflies fly in the house, and it rains only when it is dark. Shrimp cries in the rain, and there is not much rain. The flowering period is early, and the yield is reduced by half. It is sunny when spiders are netting. Spiders are hanging in the rain, and their columns and legs are wet. It rains, cows and snakes bite people, and it rains cats and dogs.

The summer solar term is just around the Mid-Autumn Festival in the dog days, which is the strongest and hottest solar term in a year, and the "hot and humid steaming" also reaches its peak at this time. The summer heat is the season with the most thunderstorms and abundant rainfall. High temperature and rainy period are basically the same, and rain and heat are the same. Monsoon climate is the main feature of China climate.

In summer, affected by the warm and humid air flow from the ocean, many places in China are hot, humid and rainy. At this time, the sun is fierce, the temperature is high, the humidity is high, and there is much rain. Although it is inevitable to suffer from damp heat, it is very beneficial to the growth of crops, and crops grow fastest during this period.

The summer solar term is the period with the strongest sunshine and the highest temperature in South China, the period with the richest rainfall, the most common thunderstorm and the most concentrated high temperature days in the west of South China, and the period with the highest temperature above 35℃ in the east of South China. Summer is also the hottest period of the year in most parts of China.

Except the Qinghai-Tibet Plateau and Northeast China, the weather is hot in most areas, with high temperature of 35℃ common and high temperature of 40℃ occurring from time to time. The temperature difference between north and south in this country is not great. In the northern inland areas, summer is dry and hot.

China is a typical monsoon climate, which is controlled by subtropical high and other atmospheric circulation systems. From mid-June to mid-July, the main rain belt in eastern China generally extends from South China and Jiangnan to Jianghuai area. Entering the end of July ("seven drops and eight liters") is equivalent to the period from the intense heat to beginning of autumn, accompanied by the seasonal northward movement of the subtropical high circulation system.

The southwest monsoon will also push northward, and the southwest wind around the subtropical high will transport the tropical and subtropical warm and humid airflow to the northern region, where it will meet the cold air in the mid-latitude of North China and Northeast China, and North China and Northeast China will begin to enter the rainy season. Northwest China is the arid area with the least annual precipitation in China, because it lives inland and far from the ocean.
