Summer phenomenon

The high temperature phenomenon in summer is as follows:

Phenological characteristics of intense heat: 1. Eagle is a sacrificial bird; Second, wait for the beginning of heaven and earth; Three Hou he naideng. It means that the eagle began to hunt a lot of birds; Everything between heaven and earth began to wither; Millet, millet, rice and sorghum began to mature. The temperature drops.

It is not enough to describe the summer solar terms from the end of August to the beginning of September simply by the beginning of temperature drop. Temperature drop is just one of the phenomena. The reasons behind this phenomenon are as follows: first, the direct point of the sun continues to move southward, and the solar radiation weakens; Second, the subtropical high moved southward by leaps and bounds, and the Mongolian cold high began to itch to try, punching and kicking, showing its edge.

Long summer is the 14th solar term among the 24 solar terms, and autumn is the second solar term. August 22-24 of the Gregorian calendar every year. Being in the heat is "out of the heat", that is, out of the heat. People usually worship their ancestors in summer, welcome autumn, eat bibimbap and so on.

Summer has reached the "last summer" of the hot weather "three summers", the temperature will not be abnormal, and the unbearable hot weather has come to an end. After the summer solar term, thunderstorm activity is not as active as that in hot summer, and the general trend of heavy rain in various places is weakened. There are many folk activities in summer, such as eating ducks, setting off river lanterns, opening fishing festivals, decocting medicinal tea and offering sacrifices to the land.

Old duck tastes sweet and cool, so it is also customary to eat duck in summer. There are many ways to do it, such as boiled duck, lemon duck, ginger duck, roast duck, lotus leaf duck and walnut duck. Beijing still retains this tradition. Usually in summer, Beijingers will go to the store to buy lily ducks and the like.

When we are in summer, it is very harmful to our lungs. Autumn dryness will not only hurt people but also hurt the lungs, so we should develop the habit of drinking more water.

"autumn tiger" in south China;

Although the subtropical high, which is dominant in summer, strides south, it will never give up its advantage easily and retreat to the sea of the western Pacific easily. In the southern region under its control, people who feel a little cold in autumn often feel hot weather at the end of summer, which is a veritable "autumn tiger".

For areas that are out of the dog days and have severe summer drought, if they continue to be controlled by subtropical high, it is often easy to form drought in summer and autumn, which greatly advances the fire prevention period in autumn and needs vigilance. What needs to be said is that the middle and lower reaches of the Yangtze River often welcome the crisp autumn spring after the autumn tiger weather, but it will wait until after 10.
