Climatic characteristics of Chang Xia Hou

The climate in Xia Hou is characterized by hot and humid weather, which is prone to thunderstorm and high temperature.

1, the temperature rises.

After the long summer, the temperature rises gradually, especially in the south. Because the temperature on the mainland is rising rapidly, it is impossible to release water, so there will be drought.

2, wet and rainy.

In the late summer, the humidity will gradually increase, especially in the south. Rainy weather often occurs at this time, so pay attention to safety when going out. At the same time, due to the increase of air humidity, it is easy to cause allergies, skin infections and other diseases.

3. Thunderstorms are frequent.

At this time, due to the formation of atmospheric pressure conditions such as high water vapor content and frequent upward movement, it is easy to form thunderstorm weather accompanied by strong convective phenomena such as lightning, which mostly occurs at night.

4, sunscreen and moisturizing.

After the long summer, the solar radiation is getting stronger and stronger, so it is necessary to do a good job of sun protection. At this time, the air humidity increases, which easily leads to dry skin, so it is necessary to do a good job of moisturizing.

5. Agricultural production.

Long summer is an important agricultural solar term. At this time, farmers should strengthen field management, water and fertilize in time to ensure the normal growth of crops. At the same time, pay attention to prevent natural disasters, such as heavy rain and floods.

In a word, the climate characteristics of ChangXia Hou can be summarized as hot and humid, with many thunderstorms. Attention should be paid to prevent skin allergy or infection, strengthen field management and ensure crop growth.

Expand knowledge:

Every year around the first day of April (between May 5 and 6 of Gregorian calendar), when the sun reaches 45 degrees of the Yellow Meridian, it is the long summer solar term of the lunar calendar. "Sinus refers to the southeast, Wei refers to the long summer, and everything grows here, so it is named long summer."

At this time, the longitude of the sun is 45 degrees. Astronomically, Chang Xia said that bidding farewell to spring is the beginning of summer days. When the temperature rises obviously, the summer heat comes, thunderstorms increase and crops enter the peak season, people are used to taking long summer as an important solar term.

In ancient China, beginning of spring, Changxia, beginning of autumn and beginning of winter indicated the arrival of spring, summer, autumn and winter respectively. Meteorology takes the average temperature of five days as the standard. When the average temperature stably passes 10℃ for five days after winter, it means beginning of spring; when the temperature is higher than 22℃, it means long summer.
