What is the weather change similar to changing seasons in many places in Northeast China or the next day?

The weather in many places is particularly unpredictable now. It's still hot today, and it will be as cold as winter tomorrow. There are natural reasons for this weather change, but there are also human factors. Let's analyze it below.

1, natural reasons,

There should be no doubt about this. Natural causes, including solar radiation, geographical location and climate change, may all cause weather changes. For example, there is a tropical climate, and the most important thing is that besides heat, it often rains, and it is sudden. For some temperate continental climates, the change is relatively small, showing a trend rather than a cliff.

2. For human reasons,

This reason should be said to be the most important and serious one at present, because now the society is more and more developed, which will inevitably cause some environmental pollution, such as industrial sewage discharge, automobile exhaust, and various acts that destroy the environment, such as cutting down trees, which are the main reasons for the unpredictable weather. Just like when I was a child, the weather forecast was very accurate. Now it is sunny in the morning and it will rain heavily in the afternoon, and the weather is getting faster and faster. Especially in Central China, it will be very hot at the beginning of spring, and the temperature can reach 20 degrees, but after a few days, the minimum temperature can drop to MINUS 5 degrees, and sometimes even to MINUS 10 degrees, and then slowly rebound, so there will be cliff-like cooling during this time.

I don't think natural causes are the most important factors of weather change, because it is too common to change seasons every other day in many places in Northeast China, which is mainly related to people's damage to the environment. Usually, people must choose public transport and try not to choose private cars. If there are too many private cars, there will be more exhaust emissions, so our weather will be white or gray every day, which is very uncomfortable to look at.
