Scenery changes of slight cold solar terms

There are three stages of slight cold: the first stage is Yanbei Township, which means that geese begin to fly back to their hometown from south to north; Second, waiting for magpies to start nesting means that magpies start nesting in the cold; Third-class pheasants begin to pheasant, which means pheasants begin to sing for companions.

For the first time, although the geese are still wintering in the south, they have sensed that the sun is about to rise, and the geese began to fly back to their hometown from south to north; In the second season, magpies will brave the cold and start nesting, ready to give birth to offspring; The pheasant in the third stage is pheasant, and the pheasant in the mountain also sensed the spirit of the sun and began to sing for his companions. It can be seen that although the weather is cold in the slight cold solar terms, the creatures in nature can still feel the yang sprouting between heaven and earth in the ice and snow.

Slight cold is the 23rd solar term among the 24 solar terms, the 5th solar term in winter, the end of the second month of the dry calendar and the beginning of the ugly month. Fighting fingers; The meridian of the sun is 285; It is celebrated every year on June 5-7 of 65438+ 10 in Gregorian calendar. Cold air is cold for a long time, and slight cold means that the weather is cold but not extreme. Like severe cold, mild summer heat, severe summer heat and intense summer heat, it is a solar term indicating temperature change. The slight cold solar term is characterized by cold, but it is not extremely cold.

Meteorological changes of slight cold

The weather characteristics of slight cold are: it gets cold, but it is not cold yet. In the slight cold season, the direct point of the sun is still in the southern hemisphere, and the heat in the northern hemisphere is still in a state of loss. The heat absorbed during the day is still less than the heat released at night, so the temperature in the northern hemisphere continues to decrease. According to China's long-term meteorological records, the slight cold solar terms in the northern region are colder than the severe cold solar terms; But for most parts of the south, the big cold solar terms are colder than the small ones.

During the slight cold solar term, the East Asian trough developed the strongest and most stable, the Mongolian cold high and Aleutian low also reached the strongest and most stable, and the ridge scale of the westerly trough reached the maximum, which matched the strongest westerly intensity. The cooling process of cold air is frequent in the slight cold season, but few of them reach the cold wave standard.
