Will it still be cold after the spring equinox in 2019? Will the weather turn warmer?

There are often obvious weather changes around the vernal equinox. The temperature has risen significantly and the weather is gradually warming up.
The middle and lower reaches of the Yangtze River and the Huanghuai region have also entered the spring defined in climatology, with the average temperature basically stable at above 10℃.
However, the vast area north of the Yellow River is still in the transition stage from winter to spring, with sunny days and frequent winds, sudden changes in temperature and sometimes even "March snow".

Climate analysis of the Spring Equinox:

Sunlight <br /> On the day of the spring equinox, the sun shines almost directly on the earth's equator, and the length of day and night is almost equal everywhere in the world. After the vernal equinox, the sun's direct rays begin to enter the Northern Hemisphere, and the days begin to grow longer and the nights shorter everywhere in the Northern Hemisphere. The Spring Equinox is a relatively important solar term. It not only has astronomical significance: the day and night are equal in the northern and southern hemispheres, but also has obvious climatic characteristics. During the Spring Equinox, my country enters a bright spring except for the Qinghai-Tibet Plateau, Northeast China, Northwest China and the northern part of North China. On the vast land, willows are green, warblers are flying, grass is growing, wheat is jointing, and rape flowers are fragrant.
Air pressure conditions <br /> During the Spring Equinox, the East Asian trough weakened significantly, and the westerly belt trough and ridge activities increased significantly. Low pressure activities and cyclone development were common from Mongolia to the Northeast. The movement of low pressure guided the cold air southward, and the northern region was prone to strong winds and blowing sand. When the long wave trough moves eastward, affected by the convergence of cold and warm air masses, continuous rain and late spring cold weather will occur.
Temperature and precipitation <br /> During the Spring Equinox, except for the high-altitude mountainous areas where it is winter all year round and the areas north of 45°N, the daily average temperature in all parts of China rises steadily to above 0℃. At this time, the severe cold has passed and the temperature has risen rapidly, especially in North China and the Huanghuai Plain. The average daily temperature has risen to above 10℃ almost at the same time as the rainy areas along the Yangtze River in the south of the Yangtze River, ushering in the bright spring. On the vast land, willows on the banks are green, warblers are flying, grass is growing, wheat is growing, rape flowers are fragrant, peaches are red, plums are white, and forsythia is yellow. The southern China region is full of late spring scenes. According to climate laws, precipitation in the south of the Yangtze River increases rapidly at this time, entering the spring "peach blossom flood" period; in the vast areas of Northeast, North China and Northwest China where "spring rain is as precious as oil", precipitation is still very little, and resisting the threat of spring drought is the main problem in agricultural production.

Analysis of the principle of standing eggs on the vernal equinox!

Principle 1: On the day of the vernal equinox, the day and night are equal in the northern and southern hemispheres, the Earth's axis, which is tilted at 66.5 degrees, and the orbital plane of the Earth's revolution around the sun are in a state of relative force balance, and the Earth's magnetic field is also relatively balanced, so the egg is best able to stand.
Principle 2: There are many protrusions about 0.03 mm high on the eggshell. Three protrusions can form a triangular plane. If the center of gravity of the egg passes through this triangle, the "vertical egg" can be achieved.
