Today (March 21st), China has entered the fourth solar term of spring — — Vernal equinox After the vernal equinox, the days get longer and the nights get shorter. In a day, the sunshine not only prolongs the "on-the-job" time, but also gradually increases the heat, and most of our country enters the fastest period of time in a year. Warming up urges the process of going north in spring, and more and more people feel the breath of spring by enjoying flowers, stepping in spring, flying kites and tasting wild vegetables. China Weather Network has specially launched a national spring map to see which places will be embraced by spring during the spring equinox.
Spring is strong in the south and accelerated in the north.
It’s the vernal equinox, and it’s already mid-spring, with flowers in full bloom and strong spring scenery. All the year round, before entering the vernal equinox solar terms, most of the spring in the south is already very strong, and many places in the north are still a winter scene. After entering the vernal equinox, the sun slowly moves northward, the days are long and the nights are short, the heat of the sun is gradually enhanced, and the average temperature in the area north of the Yellow River can reach above 10℃.
At the vernal equinox, the pace of spring accelerates northward, and more places in the north will enter 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 northern Xinjiang Southern Xinjiang Basin will enter spring at this time.
The recovery is rapid and the spring breeze is booming.
On the vernal equinox, the sun shines directly on the equator, and the northern and southern hemispheres are equally divided day and night. Since then, the position of the direct point of the sun has moved northward, and the days in the northern hemisphere are long and the nights are short. Most of China’s temperatures have shown a rising state and entered the fastest period of time in a year.
The rapid warming urges the process of spring. At the vernal equinox, the pace of spring crosses from the Yangtze River to the Great Wall, and many places north of the Yellow River finally welcome the spring letter. In ancient times, the vernal equinox was also called the mid-spring moon. Under the warm sunshine in spring, everything grew, and the leaves of willow trees were no longer sparse in early spring. The mid-spring flowers such as apricot flowers and cherry blossoms also began to enter the best viewing period.
In addition to rapid recovery, the spring breeze is also the messenger who brings spring news to the north. The spring breeze in the spring equinox season often shows two faces, sometimes "blowing the face without chilling the willow wind" and sometimes "the wind suddenly sweeps away ten thousand flowers". When it is gentle, it is like a pair of hands to soothe people’s hearts, and when it is violent, it is cruel and ruthless.
During the spring equinox, the momentum of spring thunder gradually increased, and the first thunder in most parts of the south has already sounded, and it began to enter the period of frequent lightning; Many places in the north have ushered in the first thunder. The ancients also speculated about the weather through thunder. The dull thunder and rain lasted for a long time, and the thunder was a shower.
Swallows return to the north with flowers.
There are three stages in the vernal equinox: "When the mysterious birds arrive; Two Hou Lei Nai voiced; Three Hou Shi Dian. " Dark birds refer to swallows, which generally fly south in the autumn equinox and return north in the spring equinox. At the vernal equinox, the warmth in the north is getting stronger and stronger, and the return of swallows represents that spring has also reached further north. At this time, the Yellow River basin began to hear the first sound of spring thunder one after another. However, lightning, a weather phenomenon caused by the fierce collision between cold and warm air, will not be seen until the third day of the vernal equinox.
"On the fourth day of mid-spring, the spring scenery is in the middle." The spring equinox season is just the right time, and the choice of flower viewing is very rich. As soon as the begonia blooms, the white flowers fall sporadically with the spring breeze, which seems to be the trace of her coming in the earth in spring. The pear blossoms are like snow, and her strong fragrance and elegant figure complement each other, adding a touch of color to spring. Mulan, also known as magnolia, is often used by the ancients as a metaphor for the noble character of being pure and clean.
Vertical eggs, spring vegetables, flying kites in spring
In the folk, the custom of the spring equinox season is related to the spring character of Otawa. People’s activities to enjoy spring are not limited to spring flowers, but also flying kites and tasting spring vegetables. Toona sinensis and spring bamboo shoots are served on the table one after another, becoming a limited food in spring. In addition, in order to celebrate the arrival of spring, there is also the custom of separating eggs in spring in our country. As early as 4000 years ago, people believed that laying eggs on the vernal equinox was easier to succeed.
Busy farming is at the right time
At that time, the spring equinox is busy with agriculture, and spring tube, spring ploughing and spring planting are about to enter the busy stage, winter crops enter the growth stage, and wheat begins to jointing. Because the temperature rises rapidly and the water demand of crops is relatively large, it is necessary to strengthen water storage and moisture conservation in the northern spring rainy area.
It’s another year of deep spring! During the spring equinox, as the weather warms up, people’s activities of enjoying spring begin to be colorful. Whether it is enjoying the scenery in spring, flying kites, tasting spring vegetables and experiencing the spring on the tip of the tongue, it has added some fun to daily life. After the vernal equinox, the days are getting longer and the sun is shining on the earth. Hope is ahead. Let’s start from spring and go to the future with such a mood.
