English Dictionary

geostrophic wind

名詞

(meteorology) A wind whose direction and speed are determined by a balance of the horizontal pressure gradient force and the force due to the earth's rotation to the left in the northern hemisphere and to the right in the southern hemisphere.

日本語の意味

地衡風：水平な気圧勾配力と地球の自転による力（北半球では左、南半球では右）との釣り合いにより、その方向と速度が決定される風のこと。

Meteorologists often model the large-scale geostrophic wind to estimate upper-atmosphere circulation because its direction and speed result from a balance between the horizontal pressure-gradient force and the Coriolis force.

気象学者はしばしば大規模な地衡風をモデル化して上空の大気循環を推定します。地衡風は水平方向の気圧勾配力とコリオリ力との釣り合いによって向きと速度が決まる風です。

意味（1）

(meteorology) A wind whose direction and speed are determined by a balance of the horizontal pressure gradient force and the force due to the earth's rotation to the left in the northern hemisphere and to the right in the southern hemisphere.

意味（2）

(meteorology) That horizontal wind velocity for which the Coriolis force exactly balances the horizontal pressure gradient force. The geostrophic wind is thus directed along the contour lines on a constant-pressure surface (or along the isobars in a geopotential surface) with low elevations (or low pressure) to the left in the northern hemisphere and to the right in the southern hemisphere.
