The main systems affected Taiwan's weather including front, northeasterly monsoon, continental cold air-mass, easterly moving rainbelt from southern China, typhoon, tropical depression, belt of low pressure and southwesterly now, etc. Three cold waves associated with the front occurred this year. Annual mean air temperature was higher than the average, and resulted in a warmer winter. The numbers of hot-day in 2001, except that in Taipei and Hualien weather stations, were less than normal, but the numbers of cold-day were far less than normal. The decrease of cold days implied that it was an important factor caused high temperature in 2001. Annual rainfall was much higher than normal. Most rainfall was contributed by the typhoon in September. The days of heavy rainfall occurred mostly in September too. Twenty-six typhoons were formed on the northwestern Pacific in 2001, equal to normal. Seven typhoons attacked Taiwan, much more than normal. Among them, the path of Nari was weird and unexpected. It made a long stay, over forty-nine hours, on Taiwan and a record rainfall at some weather stations. The accumulated total loss in crop exceeded forty-seven thousand million NT dollars. The damage caused by typhoon was the most severe among all weather disasters, and the Toraji and Nari typhoons brought the most loss than other typhoons in 2001. |
