There will be rainy and windy weather in Beijing in the next three days, and the temperature will drop obviously at night. Why is the temperature unpredictable?

The weather in many parts of the country has changed rapidly this year.

This year, the global climate is undergoing extreme changes. For example, in the first half of this year, the northern hemisphere experienced a very serious subtropical high climate, which also led to unprecedented horrible high temperature weather in China and many countries. Chongqing and other national cities once broke through the extreme high temperature of 45℃, which had a very serious impact; As the high temperature gradually recedes, many areas in our country have ushered in a large area of cooling, and the temperature difference between day and night has become very huge. The temperature can reach 30 degrees Celsius during the day and only 10 degrees Celsius at night. Such extreme temperature difference affects the normal life of many residents.

Residents should pay attention to the weather changes.

Because the employment temperature difference in many regions and cities in China has changed greatly, many residents are very worried about their daily clothes. Many residents catch colds and other diseases during such a huge temperature difference, and even COVID-19 is more likely to infect the human body at this time; Therefore, in the face of the large temperature difference between day and night, residents should also make relevant preparations to avoid being infected with infectious diseases such as COVID-19, and relevant departments should also strengthen epidemic prevention, which should not be taken lightly.

The climate change of the earth is related to the excessive destruction of the earth's environment by human beings.

This year, the global climate is extremely bad. Extreme high temperature has greatly reduced global crop production, and extreme weather is likely to continue in the future. The great changes that have taken place on the earth now have a lot to do with the excessive destruction of the earth's environment by human beings. Because of the increasing human population, the exploitation of the earth's resources is accelerating, which also leads to the change of the earth's climate; Global greenhouse gas emissions have also increased significantly, which will lead to global warming and even the melting of solid glaciers. These consequences are unacceptable to human society, so humans should pay attention to protecting the earth's environment.
