What are the common weather systems?

Common weather systems include frontal system, low pressure (cyclone) system and high pressure (anticyclone) system.

Due to the influence of different weather systems or being in different parts of the same weather system, not only the weather changes in the same place at different times, but also the weather changes in different places at the same time.

Judgment of cold and warm peaks:

1. Look at the moving direction of the cold air mass

2. Look at the slope ahead

3. See the scope and location of the rain area?

4. Look at these symbols?

5. Did you see the changes of air pressure and temperature before and after crossing the border?

6. Look at the weather changes during and after the transit.

① Cold front: there are often strong winds, cloudy days, precipitation and cooling weather during transit; After crossing the border, the temperature and humidity decreased, the air pressure increased and the weather turned fine. ?

② Warm front: when crossing the border, it is often rainy; After crossing the border, the temperature rose, the air pressure dropped and the weather turned fine.
