Why is Suzhou so hot in 2022?

The reasons for this high temperature weather in 2022 are as follows:

1. Global warming. With the development of three industrial revolutions, mankind has entered an era of rapid development. Due to the extensive industrial development in the early stage, a large number of greenhouse gases such as carbon dioxide were discharged into the atmosphere. In addition, forest resources have been excessively cut down by human beings, thus accelerating global warming. Therefore, trillions of tons of methane buried underground in the Arctic are gradually released into the atmosphere due to the melting of frozen soil. Knowing that methane is a strong greenhouse gas will form a vicious circle of greenhouse effect.

2. Abnormal subtropical high, which mainly affects China, is "Western Pacific subtropical high". It stays in the ocean all year round. As the direct sunlight moves northward, it will gradually extend westward and rise northward, and its landing will affect many areas in China. This year, the subtropical high moved abnormally to the northwest. Subtropical high will cause a large number of downdraft, and the temperature and pressure of the airflow will increase during the sinking process, which leads to the rare high temperature weather in northern China. Sichuan basin is the most enduring area affected by subtropical high.
