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.
