High pressure weather and low pressure weather

Low pressure wet high pressure dry, we call it winter cold high pressure, high pressure temperature is low, low pressure temperature is high.

1, the higher the altitude, the lower the temperature.

2. The ascending process consumes energy. At a certain time, when the energy is consumed, the temperature will start to drop.

The principle is: low temperature, small gas expansion, so high density, so high pressure.

With the increase of height, the air density decreases and the air pressure decreases. At the same height and high temperature, the air rises and the air pressure drops; On the same horizontal plane, air always flows from the high pressure area to the low pressure area.

Wind zone of global pressure zone and its seasonal displacement;

1. Definition: Global and regular atmospheric movement.

2. Function: Regulating the global water and heat distribution is an important factor in the formation of weather and climate in various places;

3. Influencing factors: uneven heating in high and low latitudes and geostrophic deflection.

4. Under the condition that the spherical surface of the earth is uniform and the earth rotates, the atmosphere is formed under the joint action of horizontal pressure gradient force and geostrophic deflection force, and there are seven pressure zones and six wind zones.
