Is spring coming? (Tell you about nature)
2023-02-02
At the beginning of spring, China's Guangdong, Guangxi, southern Yunnan, southeastern Fujian and other places often have entered spring; Southeast Sichuan, northern Fujian and other places gradually enter spring in February; Spring starts in March and April in most parts of the Middle East; In the eastern part of Inner Mongolia, Heilongjiang and most parts of the Qinghai-Tibet Plateau, the beginning of spring in May and June is the first of the 24 solar terms. Standing means "beginning"; Spring represents warmth and growth. The beginning of spring is usually from February 3 to 5 every year, and the beginning of spring this year is on February 4. As the proverb goes, after eating the spring meal, every day is warm. With the gradual warming of the weather, the sunshine and rainfall in southern China have gradually increased, and some places have "blown cold willow wind". However, China has a vast territory, and the climate difference between the south and the north is large. At the beginning of spring, most areas in the north are still relatively cold, and some places are still snowing, and it has not entered the natural sense of spring. According to the meteorological standard for the beginning of spring, when the sliding average temperature is greater than or equal to 10 degrees Celsius for five consecutive days, the first day to reach this standard is the start date of spring. According to this standard, there are significant differences in the process of entering spring from south to north. At the beginning of spring, China's Guangdong, Guangxi, southern Yunnan, southeastern Fujian and other places often have entered spring; Southeast Sichuan, northern Fujian and other places gradually enter spring in February; Spring starts in March and April in most parts of the Middle East; Spring in eastern Inner Mongolia, Heilongjiang and most parts of the Qinghai-Tibet Plateau will wait until May to June. In recent years, with the global warming, the beginning of spring in most parts of China has been gradually advanced, and the beginning of spring in the middle and lower reaches of the Yangtze River is generally 5-10 days earlier than that in the 1980s. "The green emperor came from the east and the sun came late, and the warm smoke blew gently against the morning wind". Spring means that the wind is warm and the sun is warm, and it also means that all things grow. People work hard and spring comes early. After the beginning of spring in all parts of the country, the work of spring planting and planting has also been carried out from south to north. It is worth noting that spring is in the adjustment period of atmospheric circulation, with frequent cold and warm air activities. If the cold air goes south and meets with the warm and humid air in the south, it is very easy to form a continuous low temperature, overcast and rainy weather, and the phenomenon of late spring cold will occur. From March to April every year, the cold weather in late spring is easy to cause early rice rotten seeds and seedlings in the south, and will have a great impact on the growth of winter wheat and forest fruit in the north, so we should pay attention to prevention. In the beginning of spring, although the weather began to warm slowly, the temperature difference between morning and evening was still large. On the one hand, we should pay attention to the latest weather forecast and early warning information to provide guidance for travel; On the other hand, in most areas, we should also pay attention to keeping warm. The folk saying "cover the spring and freeze the autumn" is reasonable. Pay attention to keeping warm can make our body gradually adapt to the changeable weather. We can use multi-layer dressing method to cope with weather changes and protect our health. (Outlook New Era)
