How much does the air pressure system affect the weather?

In a certain area, the influence of atmospheric pressure system on the weather is dominant, and their position and intensity change with the seasons. These air pressure systems were located in July, which was the rainy season in India. However, in June+10, 5438, a low-pressure area named "Aleutian" moved along the coast of Alaska and disappeared in summer, which triggered the Asian storm again and moved it to the Pacific Ocean, affecting North America. Similarly, the North American storm was moved over the subtropical Atlantic Ocean, forming a low pressure in Iceland: it re-entered Europe. In this case, all the physical factors that affect the weather-water vapor, air pressure and air mass-are playing a role at the same time, causing great influence.
