What's the difference between aviation, airport and air traffic control weather forecast?

According to the satellite cloud picture, barometric map and wind direction map, the weather development trend in an effective period of time in the future is inferred. Air traffic control includes the weather forecast of stations and routes, and the influence of precipitation, typhoon, cold and warm fronts, bumps and thunderstorms on flight. The weather forecast of the airport basically belongs to air traffic control, which mainly observes and forecasts the weather near the airport and issues daily weather reports (once every hour or half an hour), mainly including wind direction and speed, dominant visibility and visibility. TAF forecast forecasts the weather for a period of time, mainly including dominant visibility and important weather phenomena.

The weather forecast of airlines is mainly to see what impact it has on the company's operation, to know the airport information with bad weather in real time and to provide information for dispatchers and pilots.

Due to the influence of observation method, calculation method and experience, the meteorological forecast will have different results, and even many famous meteorological observation and forecast institutions abroad may make different forecasts, so there is no waste.
