What do the green and purple areas in meteorology represent respectively? ,,

The green and purple areas on the weather map are explained as follows.

The purple area is a gale area above level 6, and the green part is an isobaric wet line.

The isobaric wet line can divide the rainfall in different areas, and the windy area refers to the area where windy weather occurs, with different grades.

There are two main types of meteorological maps: ground meteorological maps and high-altitude meteorological maps. The values and symbols filled in the ground meteorological map include sea level pressure, temperature, dew point, cloud shape, cloud amount, visibility, wind direction, wind speed, current weather, past weather, etc.

Draw isobars according to the air pressure value on the map, and mark various weather systems, weather situations and their weather distributions in combination with temperature, dew point and weather phenomena.
