Spring climate characteristics in various parts of my country:

(1) Large temperature changes: People generally regard spring as the beginning of the year, when everything is renewed and full of vitality, but spring is also the middle of the year The period with the greatest weather change is the period when the temperature changes from warm to cold and the temperature changes suddenly. The temperature difference during a day is the largest in spring. Taking Beijing as an example, the difference between the highest temperature and the lowest temperature on May 3, 1966 was as high as 26.8°C. Therefore, in spring, you should listen to the weather forecast in time, pay attention to weather changes, and add more clothing in a timely manner.

(2) Dry air and how windy it is: Spring is in the period of atmospheric circulation adjustment, and cold and warm air activities are frequent. In addition to the large temperature changes, dry air and windy weather are another feature. Spring is the transition season between winter and summer. The forces of cold and warm air are equal and active, so windy weather often occurs, especially in northern my country. It is characterized by alternating north and south winds with relatively strong winds. Generally speaking, the phenomenon of frequent north and south winds will get better after May. The arrival of a strong windy weather brings cold air, the temperature drops, and the air humidity also decreases. It is easy to cause colds, rhinitis, arthritis, mental illness, skin diseases and other diseases.

(3) Dusty weather in the north: As the temperature rises in spring, if there is less precipitation and the ground is dry, when strong winds come, sandy and dusty weather will easily occur. Meteorologically, dust weather is divided into floating dust, blowing sand, and sandstorms. In northern my country, March and April are still the most frequent periods for sand and dust weather. The result of sand and dust weather is a sharp increase in various suspended particles in the atmosphere, especially the concentration of inhalable particulate matter that is harmful to the human body, resulting in a decline in air quality. There are many allergenic substances in these suspended particles, which can easily induce allergic reactions in people with allergies, thereby causing allergic diseases such as allergic dermatitis, allergic rhinitis, asthma, and urticaria. People with allergies must stay away from these allergens, and pay attention to personal precautions when going out.

(4) Rainy weather in the South: Cold weather with continuous rain and little sunshine for several days or even months in early spring or late autumn in China. Also known as low temperature and continuous rain. In the south, spring is often cloudy and rainy, with low and warm temperatures alternating. During the rainy season, the humidity is high, which can easily cause rheumatoid arthritis. In addition, it also has a great impact on people's psychological diseases, so special attention should be paid to spring. Adapt to nature and climate changes.
