There major factors determine how air circulates in the atmosphere and helps distribute heat and moisture from the tropics to other parts of the world. First is the uneven heating of the earth’s surface by the sun. air is heated much more at the equator, where the sun’s rays strike directly, than at the poles, where sunlight strikes at a slanted angle and spreads out over a much greater area. These differences in the distribution of incoming solar energy help explain why tropical regions near the equator are hot, why polar generally have intermediate average temperatures. Temperature also generally becomes progressively colder as elevation above sea level increases in the lower atmosphere.
A second factor is the rotation of the earth on its axis. As the earth rotates around
Its axis, its equator air masses rising above the equator and moving north and south to cooler areas are deflected to the west or east over different parts of the planer’s surface. the direction of air movement in the resulting huge regions in the atmosphere called cells sets up belts of prevailing winds-major surface winds that blow almost continuously and distribute air, heat, moisture, and dust over the earth’s surface.
那裡主要因素確定怎麼空氣在大氣流通，并且幫助分佈熱和濕氣從熱帶到世界的其他地區。 首先是地球的表面的參差不齊的熱化在星期日以前。 加熱空氣much more在赤道，太陽的光芒直接地碰撞，比在杆，陽光觸擊在一個傾斜的角度并且伸長在一個更加巨大的區域。 在接踵而來的solar energy幫助的發行上的這些區別解釋為什麼熱帶地區在赤道附近是熱的，為什麼極性一般有中間平均溫度。 當海拔在海水平之上在低空，增加溫度一般也變得進步地更冷。
第二個因素是地球的自轉在它的軸。 當地球在它的軸附近轉動，它的上升在赤道之上的赤道氣團和運動的南北到更加涼快的區域偏轉對整平機的表面的西部或東部不同的零件。 空中活動的方向在發生的巨大的地區在稱細胞的大氣設定了幾乎連續吹并且分佈空氣、熱、濕氣和塵土在地球的表面戰勝的風主要地面風的傳送帶。
