Performance of warm front weather

Cold front, warm front and quasi-static front are three common meteorological fronts, and cyclone and anticyclone are two important weather systems. The following are their typical features and examples:

1. cold front: the front where cold air moves to warm air is the cold front. When cold air meets warm air, it will produce rain and strong wind. Cold fronts are common in the westerlies of the northern hemisphere, such as the maritime climate in Europe and the climate in the Great Lakes region of North America.

2. Warm front: The front where warm air moves to cold air is the warm front. When warm air meets cold air, it will produce rain and the temperature will rise. Warm fronts are common in the eastern part of the northern hemisphere, such as the monsoon climate in the Great Plains of North America.

3. Quasi-static front: A quasi-static front refers to a front that stays in a certain area for a long time. This front usually appears between two air masses with similar properties, forming a narrow transition zone. Quasi-static fronts can be seen everywhere, but the rainy season in Jiangnan is the most typical.

4. Cyclone: Cyclone refers to a vortex phenomenon in the atmosphere, which shows that the airflow sinks in the center and rotates around the center. Cyclone is one of the main factors causing severe weather such as rainstorm. Tropical cyclone and extratropical cyclone are two main cyclones. Tropical cyclones mainly appear in tropical and subtropical areas, such as hurricanes and typhoons; Temperate cyclones mainly appear in middle and high latitudes, such as northeast cold vortex.

5. Anti-cyclone: Anti-cyclone refers to an anti-vortex phenomenon in the atmosphere, which shows that the airflow rises upward in the center and rotates around the center. Anti-cyclone is one of the main factors that produce fine weather and downdraft. Tropical high and temperate high are two main types of high pressure. Tropical anticyclones mainly appear in tropical and subtropical areas, such as tropical dry anticyclones; Temperate anticyclones mainly appear in middle and high latitudes, such as cold anticyclones in the Arctic.
