summer solstice temperature and climate characteristics

on the summer solstice, the sun shines directly on the Tropic of cancer, which is the longest day of the year in the northern hemisphere. Most of the days from sunrise to sunset in Sichuan are about 14 hours. Although the summer solstice has the longest day and the highest solar altitude angle, it is not the hottest time of the year. Because the heat near the formation continues to accumulate at this time and does not reach the maximum. After the summer solstice, the agricultural production in the basin of our province entered the period of field management due to the vigorous growth of crops and the rapid growth and spread of weeds and diseases and pests. The plateau pastoral area began the golden season of grass, fertilizer and livestock. At this time, the rainfall in the west of the basin increased significantly, which gradually transformed the distribution situation of more rainfall in the East and less rainfall in the West into more rainfall in the West and less rainfall in the East since spring. If there is a summer drought, it is generally expected to be relieved at this time. In the past 30 years, although the number of large-scale floods in the western basin in late June is small, the degree is relatively serious. Therefore, special attention should be paid to flood control preparation. The summer solstice is the solar term with the largest annual rainfall in the eastern part of the basin. In the future, it is often controlled by the subtropical high, resulting in summer drought. In order to enhance the ability of drought resistance and capture agricultural harvest, it is an important measure to grab and store the rainwater before lodging in these areas. After the summer solstice, the ground is heated strongly and the air convection is strong. Thunder showers are often formed from afternoon to evening. This kind of hot thunderstorm comes and goes quickly, and the rainfall range is small. People call it "summer rain across the farmland". Liu Yuxi, a poet of the Tang Dynasty, skillfully borrowed this kind of weather in Sichuan and wrote a famous poem "the sun rises in the East and rains in the west, but there is sunshine in the road".
