※ 引述《Yenfu35 (宇文正平)》之铭言:
: 第一次到这里来提问题,请多指教。
: 两回归线附近,因气流沉降的关系,
: 当地大气少有平面流动,称为「副热带无风带」,
: 别号「马纬度无风带」。
: 我的问题是:
: 此与「马」何干,所以要叫「马」纬度无风带?
: 就这样,谢谢!:)
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.
