Geographical problems. . Excuse me, please tell me the geographical front map. . What do you think of this . I won't. . .

Figure 1: Warm front.

analysis: a. meaning: the warm air mass moves to the cold air mass actively

? B. Front: semicircle, facing the cold air mass (that is, 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 passing: before passing: controlled by a single cold air mass, high pressure? , sunny?

passing time: continuous drizzle (such as plum rain)

passing time: controlled by a single warm air mass, with low pressure and warmth

Figure 2: cold front

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

? B. Front: triangular shape, 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)

? D cloud: drill cloud

? E influence of cold front passing: before passing: when controlled by a single warm air mass

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

after passing: when controlled by a single cold air mass, the weather turns fine

Note: the wind blowing from the equator is warm, corresponding to the warm front

? The wind blowing from the two stages is cold, corresponding to the cold front

as shown in figure

?

? If it is not affected by other factors, < P > it can be judged that it is in the northern hemisphere.
