The first section "The Atmospheric Thermal State and Atmospheric Movement-Thermal Circulation and Wind" ppt (Chinese version required one) courseware
Compulsory Part 1 of the Chinese board: "The Atmospheric Thermal Conditions and Atmospheric Movement-Thermal Circulation and Wind" ppt What is the root cause of atmospheric movement? What is the change in horizontal air pressure distribution caused by vertical air movement? How does air move? 1. The uneven heat and cold on the ground is the root cause of atmospheric movement. 2. Where heated, the air expands by heating, and low air pressure is formed near the ground, corresponding to high altitude, high air pressure is formed; where it is cooled, air shrinks and sinks, high air pressure is formed near the ground, and corresponding high altitude forms low air pressure. 3. In the horizontal direction, air flows from the high-pressure area to the low-pressure area, forming a thermal circulation.
