Since June this year, many places in northern China have had a lot of rain.
For example, Beijing has received twice as much rainfall as before.
Dark clouds often appear suddenly, heavy rain starts, and then it stops as soon as it ends.
The weather is hot and humid, making many people in the north feel as if they were in a summer in southern China.
In China, there is a saying about the rainy season in northern China: “seven down, eight up.”
It means that from late July to early August each year is the time when northern China gets the most rain.
But this year, before that time arrived, there had already been a lot of rain.
Many people asked: Has the rainy season in northern China started earlier this year?
Meteorological experts explain that the rainfall in June was mainly caused by active cold air, and the real rainy season has not actually begun yet.
However, looking at data from recent years, the rainy season in northern China has indeed changed.
First, the rainy season has become longer.
In the past, the rainy season in northern China usually lasted only about 30 days, but in recent years it often lasts more than 40 days.
Second, the amount of rainfall has increased, and heavy rainstorms have become more common than before.
Why have these changes happened?
Experts point out that this has a lot to do with global warming.
Global warming increases the amount of water vapor in the atmosphere and makes extreme weather more likely.
The changes in the rainy season in northern China are exactly the result of global warming.
In the face of climate change, experts remind everyone not to judge today’s weather by old experience.
Both cities and individuals should prepare in advance for rain and disasters.
At the same time, for the long-term future, we should protect the environment and choose greener lifestyles more often.
This is the best way to respond to climate change and protect the Earth.
