What are the characteristics and customs of the vernal equinox solar terms?

The characteristics and customs of the vernal equinox solar terms are as follows:

Features: Day and night are almost equal.

The spring equinox solar term is a very important solar term. In a day, the time of day and night is basically the same, which is the fourth of the 24 solar terms. In ancient China, beginning of spring, Changxia, beginning of autumn and beginning of winter were used to indicate the beginning of the four seasons.

The vernal equinox, summer solstice, autumn equinox and winter solstice are in the middle of each season. On the vernal equinox, the sun shines directly on the equator, and the time between day and night is equal all over the earth. Therefore, in ancient times, the vernal equinox was also called the "day and night equinox". There are many interesting proverbs about this.

Customized: vertical eggs

The custom of laying eggs at the vernal equinox actually comes from a sentence, "When the vernal equinox arrives, all eggs look good." This day is the most easy time to get an erection. The reason is that the vernal equinox is a day in which day and night are equal in the northern and southern hemispheres. The inclination of the earth's axis of 66.5 degrees is in relative balance with the orbital plane of the earth around the sun, which is very conducive to the erection of eggs. Laying eggs at the vernal equinox can increase our fortune and make the following days smooth.

What are the natural phenomena on the vernal equinox?

1, the length of day and night is equal.

On this day, the sun shines almost directly on the equator of the earth, and the whole world is almost as long as day and night, but this is without considering the refraction of sunlight by the atmosphere and the shadow in the morning. Therefore, on the vernal equinox, the length of day and night is the same, but the northern and southern hemispheres are different.

So correspondingly, at the vernal equinox, the direct point of the sun is on the equator, and the seasons in the northern hemisphere are opposite. In the northern hemisphere, it is the vernal equinox, and in the southern hemisphere, it is the autumnal equinox. So the autumnal equinox is as long as day and night, which means that there are two days in a year as long, and both day and night are 12 hour.

2. cold spring

Late spring cold is also a natural phenomenon at the vernal equinox, which is caused by low-pressure activities and cyclone development. It is windy and windy in the north, but continuous rainy weather and late spring cold will slowly appear in most areas.

Step 3 preheat

The vernal equinox season also represents the time when the temperature rises rapidly. Except for the cold areas where it is winter all the year round and the areas north of 45 north latitude, the temperature in all parts of China has returned, and all of them are full of vitality.
