Geographical problems. . What is the geographical front? . What do you think of this? I won't. . .

Analysis: A. Meaning: The warm air mass actively moves to the cold air mass.

? B front: semi-circular, facing the cold air mass (that is, towards the moving direction of the warm air mass)

? C. precipitation: only before the front (as shown in the figure)

? D- Cloud: Cluster Cloud

? E influence of warm front crossing: before crossing: controlled by a single cold air mass, high pressure? ，sunny？

Lost time: continuous drizzle (such as plum rain)

After passing: controlled by a single heating substance, low pressure and warmth.

Figure 2: Cold Front

? A. the cold air mass actively moves to the warm air mass.

? B front: triangle, facing the warm air mass (moving towards the cold air mass)

? C precipitation: most of it is behind the front, and a small part is before the front (as shown in the figure).

? Three-dimensional cloud: borehole cloud

? E influence of cold front crossing: before crossing: controlled by a single warm air mass.

Time: rapid cooling, strong wind, heavy rain or hail (such as cold wave in the north)

After: controlled by a single cold air mass, the weather turned fine.

Note: the wind blowing from the equator is warm, which corresponds to a warm front.

? The wind blowing from the two floors is cold, which corresponds to a cold front.

? If it is not affected by other factors

It can be judged that this is in the northern hemisphere.
