Does it rain heavily in Guangzhou? Can it affect the plane landing?

No matter how heavy the rain is, you can land as long as there is no thick water on the runway. Apart from foggy and snowy weather, the main factor affecting landing is wind. If the crosswind is too strong,

Or wind shear

If it is too strong, you have to consider alternate airports. Thunderstorm weather is often accompanied by heavy rain and strong wind shear, and sometimes there is a strong waterfall, which is very dangerous for low-flying aircraft. This airflow will shoot the plane directly on the ground, so it is often impossible to land. But don't worry about heavy rain, such as rain clouds, which are stable, but will only reduce visibility. At present, large aircraft have precision approach and landing systems, referred to as ils, which do not require high visibility, as long as they can see the runway at the decision-making height and make sure they can land. There are still many, if you still don't understand, you can ask.
