Aviation meteorological cloud code

Aviation meteorological cloud refers to the meteorological cloud encountered by aircraft during flight, and its coding usually adopts the standards formulated by ICAO. The following are some commonly used codes for aviation meteorological clouds:

* CAVOK: The sky in Wan Li is cloudless, and the weather is clear, so you can fly normally.

* BECMG: the weather is unstable, and it may be cloudy and windy. Pilots should fly carefully.

* ITCZ: tropical climate, hot and humid weather, a lot of clouds and thunderstorms, pilots should avoid passing through this area.

* Frontal: Frontal cloud, usually refers to the cloud formed when cold and warm air meet. Pilots should avoid flying in front of clouds.

* Cumulonimbus clouds: Cumulonimbus clouds are usually accompanied by severe weather such as lightning, rainstorm and hail. Pilots should avoid flying in cumulonimbus clouds.

* High-level clouds: High-level clouds usually refer to clouds with a height of more than 6,000 meters. Pilots should avoid flying in high-altitude clouds.

* cirrocumulus: cirrocumulus, which usually refers to clouds above 6000m. Pilots should avoid flying in the cirrocumulus.

* cirrostratus: cirrostratus, usually referring to clouds above 6000m. Pilots should avoid flying in the cirrostratus.

It should be noted that the code of aviation meteorological cloud is not unique, and different meteorological conditions and regions may have different codes and standards.
