Step-by-step explanation:
In hot weather, planes can struggle to generate enough lift during take off because warm air is thinner than cool air. Some researchers warn that as the climate changes, cancellations due to high temperatures may become more common.
Every aircraft has a maximum operating temperature, which is set by the manufacturer and approved by regulators. If the air temperature exceeds that limit then planes are not permitted to take off.
Fog, snow, ice and crosswinds mean that air traffic controllers have to increase the gap between planes that are landing, reducing the number of aircraft that an airport can manage. The same weather can make it slower and more difficult for the planes to taxi between runway and terminal building.
