The national map of spring shows where spring is.

National spring map, to see where spring is, is an activity launched by China Weather Network, to see which places will be put into the embrace of spring at the vernal equinox.

Spring map: Spring is strong in the south and accelerated in the north.

At the vernal equinox, it is already mid-spring, with flowers in full bloom and strong spring. Throughout the year, before entering the vernal equinox and solar terms, the spring in most parts of the south is already very strong, and many places in the north are still a scene of winter. After entering the vernal equinox, the sun slowly moves northward, the days are long and the nights are short, and the solar heat gradually increases. The average temperature in the area north of the Yellow River can reach 10℃.

On the occasion of the vernal equinox, the pace of spring accelerates northward, and more places in the north will fall into the embrace of spring. Central and northern Jiangsu, northern Anhui, northern and western Henan, southwestern Shaanxi, southwestern Shanxi, most of Hebei, most of Tianjin, most of Beijing, and southern Xinjiang basin in northern Xinjiang will enter spring at this time.

Characteristics of vernal equinox:

At the vernal equinox, the momentum of spring thunder gradually increased, and the first thunder sounded in most parts of the south, and it began to enter the lightning-prone period; Many places in the north ushered in the first thunder. The ancients also speculated about the weather by thunder. The dull thunder and rain lasted for a long time, and the thunder was a shower.

During the vernal equinox, the warmth in the north is getting stronger and stronger, and the return of swallows represents that spring has also arrived further north. At this time, the Yellow River basin began to ring the first sound of spring thunder.

In the folk, the custom of the vernal equinox season is related to Dachuan's spring character. People enjoy spring activities not only in spring flowers, but also flying kites and tasting spring vegetables. Toona sinensis and spring bamboo shoots have come to the table one after another, becoming the limited food in spring.
