How to judge the cold front in high school geography

At the intersection of cold and warm air and high pressure and low pressure, cold air is high pressure and warm air is low pressure. When the cold air mass plays a leading role, the front where cold air moves in the direction of warm air is called cold front. The cold front passes through a lot of stormy weather, and there is a lot of windy and cool weather behind the front; When the warm air mass plays a leading role, the front that pushes warm air to move in the direction of cold air is called warm front, and it passes through the border in rainy weather. After crossing the border, warm air took the place of cold air, so the temperature generally rose.

In other words, the cold and warm fronts depend on which plays the leading role.

For example, in winter, influenced by the cold air from Siberia, a cold front pushes southward in China. Cold air sinks heavily and warm air floats lightly, which is a cold front, and it is easy to form precipitation and cool down, with snowfall below 0 degrees and rainfall above 0 degrees.

Simply put, if you look at it, cooling down after rain is a cold front, and warming up is a warm front!
