Which areas are greatly affected by severe weather such as cold wave and tropical storm? why

Cold waves are generally affected by cold air in the upper level, and tropical storms are generally at 15-30 degrees, mostly in Asia and America. Due to geostrophic deflection, tropical storms formed at the equator, affecting southeast China, South Asia, Africa and a small part of America. Generally, tropical storms with a certain wind force in the United States are called hurricanes, right?

The mountains in America are mainly distributed on the west coast.

In the middle is the Ma Pingchuan Plain, where the Canadian cold current can sweep across the North American continent from north to south without interruption.

Tropical storms are mainly caused by the periodic changes of the Atlantic warm current.
