Geostrophic wind | 地轉風

地轉風(Geostrophic wind) 地轉風(Geostrophic wind) 是一種科氏力和氣壓梯度力 (Coriolis force and the pressure gradient force)巧妙平衡下產生的一種理論上的風。這個狀況稱為「地轉平衡」 (geostrophic equilibrium or geostrophic balance)。 地轉風的方向和等壓線平行。 這

Jet Stream | 高速氣流

高速氣流(Jet Stream),或稱噴射氣流、高空急流、極鋒噴流、噴流、激流,是行星尺度的大氣環流。在地球上,指數條圍繞地球的強而窄的高速氣流帶,集中在對流層頂,在中高緯西風帶內或在低緯度地區都可出現。其水平長度達上萬公里,寬數百公里,厚數公里。中心風速有時可達每小時200至300公里的偏西風,而且可以有一個或多個風速極大中心,具有強大的水平風切變和垂直風切變。高速氣流附近亦有強大風切變,這也是
