空氣在流動的時候,所有樹木花草的枝葉都動搖超來。從煙囱裏冒出來的煙亦随着流動的空氣飄搖下定,我們把這種地面上空氣流動的現象叫作風。引起空氣流動的主要原因,是由於地球表面上的溫度分佈下均匀所形成的高低下同的氣壓的作用。假說地球不轉動熱力均勻的分佈,地平面上就 As the air flows, the foliage of all trees and plants shakes. The smoke coming out of the chimney is also set with the flowing air. We call this phenomenon of air flow on the ground as the wind. The main cause of the air flow is the effect of uniform air pressure on the surface of the earth. The hypothesis is that the earth does not rotate evenly in its distribution of heat;
