Spring arrives 20 days early in these places

　　With the arrival of March, most of the country has gradually entered a warming rhythm.

　　Jia Xiaolong said that at present, most areas in the western Huanghuai River, the middle and lower reaches of the Yangtze River and the south have entered spring.

Compared with normal years, spring arrives earlier in most of the above-mentioned areas, especially in the western Huanghuai, western Jianghuai, areas along the middle and lower reaches of the Yangtze River, southern Jiangnan, and southeastern Southwest China. Spring arrives more than 20 days earlier than normal.

　　It is expected that in March, the temperature in Xinjiang, northern Northwest China, western Inner Mongolia, and western South China will be lower than normal for the same period of the year, while the temperature in the rest of the country will be close to normal to higher than the same period of the year.

The temperature in most parts of the country was low in early March, and the temperature began to rise significantly in mid-March.

　　However, due to strict meteorological standards for the onset of spring, affected by factors such as geographical location, terrain height, weather processes, etc., the onset of spring varies greatly from place to place. In a strict sense, the onset of spring needs to be combined with the temperature over a period of time. Real situation judgment.

　　Spring will arrive in Beijing in late March, which is close to the same time in normal years (March 28) and is early.
