Weather forecast method:

The most traditional data are air pressure, temperature, wind speed, wind direction, humidity and other data. Collected by professionals, amateurs, automatic weather stations or buoys on the ground or at sea. The World Meteorological Organization coordinates the timing of data collection and sets standards. These measurements are made every hour (METAR) or every six hours (SYNOP).

Meteorological data is becoming more and more important. Meteorological satellites can collect data from all over the world. Their visible photos can help meteorologists study the development of clouds. Their infrared data can be used to collect the temperature of the ground and cloud top. By monitoring the development of clouds, we can collect the wind speed and direction at the edge of clouds. However, the accuracy and resolution of meteorological satellites are not good enough, so the ground data is still very important.
