Re: [問題] 「馬」緯度無風帶？
※ 引述《Yenfu35 (宇文正平)》之銘言：
: 第一次到這裡來提問題，請多指教。
: 兩回歸線附近，因氣流沉降的關係，
: 當地大氣少有平面流動，稱為「副熱帶無風帶」，
: 別號「馬緯度無風帶」。
: 我的問題是：
: 此與「馬」何干，所以要叫「馬」緯度無風帶？
: 就這樣，謝謝！:)
horse latitudes—
The belts of latitude over the oceans at approximately 3035N and S
where winds are predominantly calm or very light and weather is hot
and dry. These latitudes mark the normal axis of the subtropical highs,
and move north and south by about 5 following the sun. The two calm
belts are known as the calms of Cancer and calms of Capricorn in the
Northern and Southern Hemispheres, respectively; in the North Atlantic
Ocean, these are the latitudes of the Sargasso Sea.
The name is believed to have originated in the days of sailing ships,
when the voyage across the Atlantic in those latitudes was often prolonged
by calms or baffling winds so that water ran short, and ships carrying
horses to the West Indies found it necessary to throw the horses overboard.
