Is there any scientific basis for the saying "an autumn rain brings a chill"? The long-standing question has finally been clarified...

This article was reviewed by Zhang Feng, meteorological engineer at the National Meteorological Center

These past few days

It's rainy in many places

After the rain

Although the sky cleared

But I still feel that the weather is getting colder

I often hear elders say

"An autumn rain brings a chill"

Actually, think about it carefully

Since the beginning of autumn

It's true

So

"An autumn rain brings a chill"

Is there any scientific basis for this?

Come and see

turn out to be

There is a saying that “an autumn rain brings a chill”

Because:

First

After entering autumn

A cold front moving south from Siberia and Mongolia

Encountered warm and humid air from the south

It forms rainfall

No matter how high the local temperature is, it cannot withstand the frequent rainfall.

Second

After the Autumnal Equinox

The sun's direct point slowly moves southward

In this way

The angle of sunlight in the Northern Hemisphere will also continue to tilt

The heat gained by the ground gradually decreases

In addition, the ground itself radiates and cools

The temperature on the ground will get lower and lower

besides

It also depends on latitude

The higher the latitude, the more cold air there is.

As it goes south again and again

The rainfall also increased

Do you all understand?

The weather will gradually get colder

Friends, please add clothes at any time.

Be careful not to catch a cold!
