Why is it so windy in Shanghai today?

The main reason is that it is affected by strong air convection, causing local or large-scale natural disasters.

The so-called air convection is actually caused by the strong vertical movement of air. This phenomenon occurs mainly because the ground absorbs a large amount of short-wave radiation emitted by the sun and releases a large amount of long-wave radiation into the atmosphere, resulting in Temperatures near the surface of the Earth rise.

And wind is also affected by strong convection weather. There are two factors in its formation. First, the ground temperature rises, and a large amount of water on the ground is evaporated into the air. Wind can be caused by the expansion of water vapor. Second, strong air convection instability causes rainfall and strong winds
