What does the hot summer time mean? There are also major departments, vertical departments and summer hyperthermia.

Summer is a little hot, that is, the weather is getting hot, but it is not the hottest, which is basically the case in most parts of the country. At this point, it is already around the beginning. Crops all over the country have entered a vigorous growth period, and it is necessary to strengthen field management. On July 7th or 8th every year, when the sun reaches longitude 105, it is considered as a slight summer heat.

The summer heat is the hottest period in a year, with the highest temperature and the fastest growth of crops. Drought, flood and wind disasters are also the most frequent in most areas, and the tasks of harvesting crops and seeds, drought and drainage and field management are very heavy. In many places in the Yangtze River basin, high temperatures of 40 degrees Celsius often occur at this time. Do a good job in heatstroke prevention and cooling, and the sun will reach the yellow meridian 120 from July 22nd to 24th every year. At this time, it is before and after the "mid-volt".

Beginning of autumn is the first solar term in autumn, and beginning of autumn is the beginning of autumn. The weather gradually turns from hot to cold, then from cold to cold, and finally transitions to cold winter. Beginning of autumn has three stages: cool breeze, dew and chill. Beginning of autumn, it means autumn is coming. However, under normal circumstances, the temperature in early autumn will not drop significantly, and you must stay in summer for a period of time before you leave completely.

Being in summer means that the hot summer weather is coming to an end. When the revolution position of the sun moves to longitude 150, the direct point of the sun moves south, and the solar radiation intensity weakens. At this time, the summer heat is coming to an end, the transformation from summer to autumn is completed, and it begins to enter late autumn. Although the summer heat has passed, don't forget that there are autumn tigers eyeing up. After the summer heat, the western Pacific subtropical high is still controlling all parts of the country. Therefore, the summer solar term may still be hot, and it will be completely cool after the autumnal equinox solar term.
