What do you mean by cold spring? Abnormal weather.

Before and after the vernal equinox, winter faded away, spring turned to the earth, and the world was full of vitality.

But the older generation is rich in life knowledge. They will tell you not to put away your thick clothes in a hurry. There is still a cold spring ahead.

So, what does this so-called "cold spring" mean? Let's have a look.

In the four seasons of the year, the season with the greatest changes in meteorological elements such as temperature, airflow and air pressure is spring, which is the transition season from winter to summer, and the summer monsoon in the high-pressure area slowly advances from the ocean to the land. Winter wind and summer monsoon, two cold and warm air masses, control each other, with frequent cyclone activities and changeable weather.

Late spring cold refers to the weather phenomenon that the temperature rises rapidly in early spring (generally refers to the end of February and the beginning of March), but the temperature in late spring cold (generally refers to April) is lower than normal. Long-term rainy weather or frequent cold air intrusion, or under the control of continuous cold and high pressure, strong radiation cooling in sunny nights is easy to cause late spring cold.

The weather phenomenon of late spring cold not only exists in China, but also occurs in Japan, North Korea, India and the United States. The reason is that spring in China (around March) is a transitional period from winter to summer monsoon, during which there are often intermittent cold air attacks from the northwest, and the cold air goes south and sticks to the warm and humid airflow in the south, resulting in continuous low temperature and rainy weather.

"A child's face changes three times a day in spring", and cold spring is the representative of spring with changeable climate. Although spring is getting warmer, it is still cold in the morning and evening, and the number of cold air activities is more frequent. The appearance of late spring cold is a test for people's health. If people take off their cotton-padded clothes too early in the spring, once the cold air strikes, they may not be able to adapt at once, and their body resistance will also drop, making them easy to catch a cold or even have a fever. Especially for the elderly with weak constitution and children with weak resistance, we should wear more clothes to avoid catching a cold and causing diseases.

Conclusion: To prevent the onset of "cold in late spring", we should pay attention to listening to and watching the weather forecast, increase or decrease clothes in a timely and appropriate manner according to the weather changes, pay attention to cold prevention and warmth, and cover more in spring according to the theory of traditional Chinese medicine. Patients with asthma and coronary heart disease should also wear more in spring to avoid the recurrence of old diseases accidentally.
