Why is it so cold this spring?
Recently, the temperature fluctuates frequently, and extreme cooling occurs in many places. Today is May, but the temperature has not risen significantly. People can't help feeling that this spring is really cold. The overall temperature is low this spring, mainly due to La Nina phenomenon and the abnormal cooling of seawater in the central and eastern Pacific Ocean.
This year, China is in La Nina state, that is, the SST in the equatorial eastern Pacific is below minus 0.5 degrees lower than normal, which has a very obvious impact on China's climate. Under the influence of La Nina phenomenon, the meridional circulation in East Asia is abnormal, which is very beneficial to the southward movement of cold air in northern China.
There is also cold air from the alpine region: the snowfall area in winter (the same as the rainfall area in summer) is distributed near the front, that is, the intersection of cold and warm air masses. This position is not fixed, but is determined by the strength of the two air masses. The cold air mass is weak, the front and precipitation areas have high latitudes, the cold air mass is strong, and the front and precipitation areas have low latitudes.
How to prevent cold weather in spring
Due to the unpredictable climate change in spring, the temperature difference between day and night is large. Therefore, we should always pay attention to the changes in the weather and increase or decrease clothes. Because our own body is resistant inside and can resist the invasion of external bacteria.
With the change of climate, we should pay special attention to increasing or decreasing clothes, and we should not use tap water to wash our hair and shower, because spring is the rainy season, and the air pressure and humidity are very low. Therefore, in the spring, we should pay attention to the appropriate addition and subtraction of clothes, exercise more to increase resistance, and pay attention to nutritional balance.
In spring, people will feel very tired. In this case, don't sleep late, go to bed early and get up early, and insist on proper exercise. For example, running, doing yoga, walking, playing Tai Chi, and eight golden flowers can make the body adapt to the rising yang in spring and enhance the body's functional metabolism and resistance. But you can't do excessive exercise and sweat too much in spring.
