Effects of Global Climate Change on Meteorological Circumstances in Globe and Taiwan Area and Strategies in Response
由於人類活動,增加了大氣中溫室氣體的濃度,加強溫室效應,導致氣候的改變,暖化了地球表面。在此氣候變遷趨勢下,對全球與臺灣地區氣象環境之衝擊與如何因應,是國際問及我國必需面臨的問題。本文主要的目的在回顧近年來有關這方面的研究與報告,並對因應之道提出一些建議。首先討論大氣中溫室效應氣體濃度變化及未來預估的可能排放量,其次探討全球與台灣歷年來氣候變化情況。過去一世紀以來,全球平均氣溫已上升約0.6℃,海水位上升約10~20公分,未來在二氧化碳濃度倍增下,估計全球氣溫與海平面將持續上升。氣候變異性所致的災害性天氣頻率將增加也將趨於更嚴重性,如此氣候環境的明顯改變,不但影響農作物的生產,也將對水資源管理與糧食穩定性造成衝擊。最後提出對溫室氣體排放減量,尤其是能源、森林及農業的控制措施,以及氣候研究與預測,水資源的永續發展與海岸變遷等因應策略。
關鍵詞:溫室效應氣體;氣候變遷;氣候變異性;永續發展。
An increase in the atmospheric concentrations of greenhouse gases resulting from human activities enhances the greenhouse effect, which results in climatic change and warms the earth’s surface. Under the tendency of the climate change, the impact on the meteorological environments in global scale and Taiwan area is an imminent problem that Taiwan and the nations of the world must face. It is the main purpose of this paper to review the related issues and selected previous studies, meanwhile, to make a recommendation and strategy in response to this problem. The variations of long-term atmospheric greenhouse gases and the estimated emissions in the future are described first. Then, the climatic changes around the globe and Taiwan area in the past are investigated. Over the past 100 years, the global mean temperature has risen about 0.6℃, the sea level has risen around 10-20cm. In the response to doubling CO2 for the coming future, the global mean temperature, the mean sea level will continue to rise. The frequency of the disastrous weather caused by the climatic variability will increase and be more severe. Such obvious changes of climatic environment not only affect crop production, but also impact the management of water resources and food supply. Finally, the response strategies, for reducing greenhouse gas emissions; especially from the energy use, forestry and agricultural control options, for the climate researches and predictions, for sustainable development of the water resources and the coastal change, are provided
Climatic Variations and Agrometeorological Disasters Occurred inTaiwan in 2001 Chih-Hsiang Liao
夲文之目的在概述民國九十年臺灣地區之氣候況及農業氣象災害全年影響臺地區的天氣系統有鋒面、東北李大陸冷氣、華南雲雨偏東移、風(含其外圍環流)、熱帶性低氣、低壓帶及西南氣流等,其中有3次寒流伴隨鋒面南下影響灣。全年年均氣溫匾髙溫且冬季偏瑗炎B數除臺北及花蓮兩氣象站多氣候平均值為正距平外,其他地方平或少於平均;寒冷日數則遠少氣候値,為造成全年平均氣匾髙的重要因素。全年年雨量屬多,雨量大部分來自於9月颱風所帶來的貢獻。豪大雨發生日數最多的月份亦集中9月民國九十年有26颱風生成與氣候相近;但其中有7個侵臺颱風,屬多侵臺颱風年,侵臺颱風中尤以納莉颱風之路徑最怪異且創下某些氣象站雨量紀錄。全年因氣象災害造烕之農作物損失金額約新臺幣47億多元,以颱危害最大,其中尤以桃芝及納莉颱風所造成的災害損失最爲嚴重。
The purpose of this paper is to describe the climatic situations and agrometeorological disasters occurred in Taiwan in 2001. 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
