[漢羅] 地球面頂 ê 氣旋路線

地球面頂 ê 氣旋是攏按怎 leh 行？ 氣旋 tī 大西洋叫做 颶風，tī 太平洋叫做風颱。 這幅圖 是 ùi 1985 年 到 2005 年 所有主要 ê 風暴路線。 地圖展示 氣旋 通常 tī 海面出現，這是合理 ê，因為溫暖 ê 海水蒸發了後會予 in 能量。 Ùi 地圖閣看會著氣旋袂 kah 地球赤道 交叉，嘛真少倚近赤道。 因為 科氏效應 tī 赤道 ê 作用是零，氣旋愛有科氏力才有法度循環。 科氏力 嘛造成 氣旋 照弧形路線走離赤道。 這款長期趨勢嘛是一个 研究主題。 有證據表示，平均來講，颶風 tī 過去 30 冬 tī 北大西洋 變甲 閣較強矣，而且 in ê 強度 看起來是會愈來愈強。

[English] Cyclone Paths on Planet Earth

Where on Earth do cyclones go? Known as hurricanes when in the Atlantic Ocean and typhoons when in the Pacific, the featured map shows the path of all major storms from 1985 through 2005. The map shows graphically that cyclones usually occur over water, which makes sense since evaporating warm water gives them energy. The map also shows that cyclones never cross -- and rarely approach -- the Earth's equator, since the Coriolis effect goes to zero there, and cyclones need the Coriolis force to circulate. The Coriolis force also causes cyclone paths to arc away from the equator. Although long-term trends remain a topic of research, evidence indicates that hurricanes have become, on the average, more powerful in the North Atlantic over the past 30 years, and their power is projected to keep increasing.
