...It is basically caused by unequal heating of the atmosphere at various latitudes and altitudes. When the two ends of a mass of air are heated to different degrees, the air expands at the warmer end, creating a pressure difference compared to the other end. This pressure difference creates a force, the pressure gradient force, that accelerates air from high pressure to low pressure, creating wind. *Some of the terminology explanations that mention "pressure gradient force" are listed below.

…これは基本的には種々の緯度と高度における大気の不均衡な加熱によってひき起こされるもので,大気の塊の両端で加熱の度合が異なると暖かいほうでは大気が膨張し他の端と比べて圧力に差が生じるためである。この気圧差のために,高圧部から低圧部へ空気を加速する力,すなわち気圧傾度力が生じ風が吹くのである。 ※「気圧傾度力」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
