Which weather system causes the most gale?

Typhoon or tropical cyclone, thunderstorm.

In the northern hemisphere, the air in the cyclone area flows counterclockwise, while in the southern hemisphere, it is just the opposite. Because the air pressure in the cyclone center is lower than that in the surrounding area, air flows into the center from all directions, causing strong winds. The continuous convergence of air flow to the center leads to upward movement, and the air flow rises to the upper air and flows out to the surrounding areas, prompting the lower atmosphere to continuously flow in from the surrounding areas to the center. Due to the vertical updraft in the cyclone center, when the cyclone passes through the border, the cloud cover in the central area increases and it is rainy.

Matters needing attention

In windy weather, the driver's visual visibility is reduced. When driving, he should pay more attention to the movements of pedestrians and non-motor vehicles, avoid sudden acceleration, deceleration and turning, and keep a longer distance from the car in front than usual. Shake the window glass as tightly as possible to prevent sand from blowing into the cab and affecting normal driving.

In case of windy weather, it is best to stay away from trees, billboards, tall buildings and other places with high risk of falling when parking. When traveling, don't drive near buildings or residential buildings with sundries to avoid accidents.
