Is the high temperature in summer the first day of stay?

The hot summer is not the first day of accommodation.

This is the third Geng Day from summer to the future. The date of Geng Day is changeable and not fixed, so the date of lodging is different every year, but the date of lodging is always between July 1 1 and July 20.

The reason why it is so hot during the summer heat is that Nanjing is often controlled by subtropical high, with high temperature and summer heat and little precipitation. In addition, usually since the summer, the heat absorbed from the ground sun during the day is more than the heat emitted at night, and the heat continues to accumulate. During the summer heat, the accumulated heat reaches the peak of J page, so the summer heat is the hottest.

Because the precipitation in China is mainly formed by the water vapor brought by the southeast monsoon, influenced by the summer monsoon, the precipitation gradually decreases from the southeast coast to the northwest inland.

Judging from the seasonal distribution of precipitation, tropical and subtropical areas in southern China are typical rainy and hot periods; The precipitation in North China and Northeast China is mainly concentrated at the turn of summer and autumn. Although the rainy season is short and the rainfall is small, it also has the characteristics of "rain and heat synchronization", so the climate in North China and Northeast China also belongs to "rain and heat synchronization". Abundant sunshine, abundant precipitation, high temperature and humid rain and heat are very superior climatic resources in China and are very suitable for crop growth.
