What kind of weather will delay flights?

The most common weather delays come from thunderstorms, complex weather, wind speed, visibility and cumulonimbus cloud coverage caused by thunderstorms at destination airports. , can not meet the landing standards, the flight that has taken off is alternate or return, and the flight that has not taken off is delayed. Cumulonimbus clouds on the route usually fly around, which increases the flight time.

Fog means that visibility can't meet takeoff or landing standards.

The delay caused by snowfall is mainly due to the need for deicing before the plane takes off, and it takes time to wait for the deicing vehicle and deicing work.

When the typhoon comes, the airport will be closed and all flights will be prohibited from taking off and landing.

Of course, there are many other reasons for the delay. The delay will lead to a series of problems later, such as aircraft deployment and crew deployment. Airlines don't want to delay more than anyone else. When there is a large-scale delay, the crew is often exhausted and the ground personnel are overwhelmed.
