Geographic Characteristic

posted May 8, 2012, 12:43 AM by Yung-tai Tu   [ updated May 8, 2012, 1:17 AM ]

     Crossed by the Tropic of Cancer, Taiwan has a subtropical climate with the exception of it's extreme southern tip, which is tropical.  Warm ocean currents give Taiwan a climate conducive to the growth of lush vegetation and two or three rice harvest per year.  With an average annual precipitation of 2,471 millimeters, rainfall is abundant.  However, the distribution of water resources is uneven, making the water available for use per capita low.  Thundershowers and the occasional typhoon bring heavy downpours in the summertime, whereas November through February is Taiwan's driest period.
