Meteorological characteristics in spring:
Spring has quietly come to you and me, and it is a new scene full of spring. However, spring is a transitional season between winter and summer. The strength of cold and warm air is equal, and they are all very active, which leads to the changeable weather in spring, sometimes sunny, sometimes rainy, sometimes warm, sometimes cold, sometimes violent, sometimes lightning and thunder. Does the baby change his face three times a day in spring? Folk songs. Wang Anshi once described spring like this: the spring breeze is sometimes good and sometimes bad, so the flowers can't bloom, and the flowers are blown down by the wind. ? This means that the weather is changeable in spring.
Today, a new round of cold air is back, which makes people unprepared. During the day, the haze turns cloudy with showers or thunderstorms. The highest temperature is 19℃, and it is cloudy with little to moderate rain at night, and the lowest temperature is 5℃. Fortunately, the rain will slowly disperse the smog, but today the weather is changeable, so everyone should try to reduce going out as much as possible. If you go out, please be prepared for rain, the visibility is low. Pay attention to slow down when you go out. Below, I sorted out the main features of the spring weather in Beijing:
(1) The temperature changes greatly.
People generally regard spring as the beginning of a year, and everything is new and full of vitality, but spring is also the period when the weather changes the most, and the temperature changes suddenly from warm to cold. The temperature difference in a day is the largest in spring. Taking Beijing as an example, the difference between the highest temperature and the lowest temperature reached 26.8℃ on May 3rd, 1966. Therefore, in spring, we should listen to the weather forecast in time, pay attention to the weather changes and increase clothes in time.
The air is dry and windy
Spring is in the adjustment period of atmospheric circulation, and cold and warm air activities are frequent. In addition to the great temperature change, dry air and windy weather are another feature. Especially in northern China, it is characterized by strong winds alternating from north to south. . The arrival of a windy weather brought cold air, the temperature dropped, and at the same time reduced the air humidity. It is easy to cause colds, rhinitis, arthritis, psychosis, skin diseases and other diseases.
(3) Dust weather in the north
In spring, with the temperature rising, if there is little precipitation, the ground is dry and the wind comes, it is easy to have dusty weather. Meteorology, sandstorm weather is divided into floating dust, sand blowing and sandstorm. In northern China, March and April are the frequent periods of dusty weather.
The result of sandstorm weather is that the concentration of suspended particles in the atmosphere, especially inhalable particles harmful to human body, increases sharply, which leads to the decline of air quality. These suspended particles contain a variety of allergens, which are easy to induce allergic reactions in people with allergic constitution, thus causing allergic diseases such as allergic dermatitis, allergic rhinitis, asthma and urticaria. Allergies must stay away from these allergens and pay attention to personal preventive measures when going out.
In addition, in spring, when flowers fall in bloom and pollen flies with the wind, patients with allergic asthma are most likely to get sick. The prevention method is to insist on physical exercise to improve the body's disease resistance; Secondly, we should pay attention to hygiene, eliminate pests and diseases, eliminate the source of the disease, keep the indoor air fresh, and open more windows.
