When was the first frost in 2020?

The first frost in 2020 is 20201Friday, October 23rd 10.

Every year around Gregorian calendar 10 year 10, when the sun reaches the longitude of 2 10 degrees, it is the first frost in the 24 solar terms. The first frost is the last solar term in autumn, which is the transition from autumn to winter. Frost is a large amount of heat dissipation on the ground in autumn, and the temperature suddenly drops below 0 degrees. The water vapor in the air of frosted plants directly condenses on the ground or plants to form fine ice needles, and some become hexagonal frost flowers, which are white and loose in structure.

Twenty-four solar terms "in mid-September, the gas is cold and condensed, and the dew is like frost". What I'm talking about here is "first frost", which means that the weather gets cold and the dew freezes into frost.

Phenological characteristics of the first frost solar terms

The ancients in China divided the fifteen days of the first frost season into three periods: the first period was when jackals sacrificed animals; Second, the vegetation is yellow; Three stings are salty.

A waiting jackal is a sacrifice to wild animals, which means that in this solar term, jackals begin to catch prey, sacrifice what they have caught first to wild animals, and sacrifice wild animals to heaven in return. Like the harvest of the new valley on the earth, it is used to worship the sky to show the return and pray for good weather in the coming year.

Second, the vegetation is yellow, paraquat is exhausted in autumn, and butterflies are flying in the frost. In autumn, the west wind is rolling and the leaves are yellow.

At this time, the stinging insects are motionless in the hole and droop their heads into hibernation. At this time, nature is a silent beauty. Bees and butterflies are gone, and the stinger is silent. They are all preparing for the long winter.
