Why does it rain heavily during the Qingming Festival?

Du Mu is the busiest during the Qingming Festival!

People are most happy

Quoting his "During the Qingming Festival, rain falls heavily"

To describe the Qingming weather

Why does it rain heavily during the Qingming Festival?

Could it be that Du Mu is also a weather forecaster?

During the Qingming Festival

The sun's direct point is from 5.9° north latitude

Gradually moving to 11.5°N

The sunshine in the Northern Hemisphere has increased significantly

At this time, the warm air has recovered some of its vitality.

The cold air

It is no longer the flood beast in midwinter.

One of them went north from the ocean

One is heading south from high latitudes

Often meet in the sky above our country

Since the warm and humid air has not yet evolved into a complete

It is difficult to gain a foothold in northern my country

The cold air travels long distances

By the time they reached southern my country, they were already exhausted.

It is difficult to cross the Vietnam Ridge

So the two of them are in tacit agreement.

A tie in the Jiangnan region of my country

This tie

It's not a handshake and call it a day.

Instead, they refused to give in to each other and continued to fight for a long time.

Cold air occupies low altitude territory like a wedge

Warm air is forced

The interface with the cold air climbs up diagonally

As you climb, the temperature drops and the water vapor gradually becomes saturated.

Finally "squeezed" out

The spring rain falls all over the land of Jiangnan

This drama is performed every year

The show lasted for one and a half months

(Usually late March to early May)

This period

It is also known as the "Jiangnan Spring Rain Period" in my country.

So the Qingming weather

It wasn't because Du Mu put a "curse" on him.

It's the old enemies of cold and warm air.

Objective facts of aerial combat

Although Du Mu was not a forecaster

But the weather observations were done very carefully

And because this poem became popular all over the country

"It rains heavily during the Qingming Festival"

It also naturally captured the hearts of many northerners.
