"Why does the climate change frequently in spring?" The temperature rises and falls.

Because the interaction between cold and warm air masses is the strongest in spring, the atmospheric state is the most unstable. Generally speaking, we are mainly controlled by cold air masses in winter. When spring came, the strength of the cold air mass began to weaken, and the warm air mass took the opportunity to compete for territory and attack the cold air mass. When the heating group wins, the temperature is higher; When the cold air mass is strong, the temperature will drop. Really love each other and kill each other, so Xi' an in March is like spring all the year round! Spring is in the adjustment period of atmospheric circulation, and cold and warm air activities are frequent. In addition to the great temperature change, windy weather is another feature.

Spring is the transitional season between winter and summer, and the cold and warm air are equally strong, both of which are very active, so windy weather often occurs, especially in northern China, which is characterized by alternating north-south winds and strong winds.

Generally speaking, the phenomenon of frequent north-south winds can be improved after May. Continued strong winds will bring great harm to transportation, water transport and facility agriculture. In addition, cold air comes and the temperature drops, which is easy to cause diseases such as colds, rhinitis, arthritis and skin diseases. In this tug-of-war between cold and warm air masses, many people were unfortunately shot and caught a cold.
