中文摘要 | 聖嬰現象是一種氣候上的異常,它所伴隨特殊天氣及影響生態方面的例子屢見不鮮。1997∼98年之聖嬰現象其強度已超越百年來所有聖嬰現象。本文經由對海平面溫度及850百帕風場之描述,進而探討可能造成異常天氣與聖嬰現象間之關聯性。一般相信,聖嬰現象開始之後第二年臺灣地區春雨普遍增加。然而1997∼98年之聖嬰現象雖然春雨仍舊豐沛,但天氣系統卻與1982∼83年聖嬰現象頗不相同。旺盛的西南氣流造成臺灣西南部的暖冬現象,並使臺灣持續數個月的高溫型態。 |
英文摘要 | El Nino has been known to be a special event in Climatology. Unusual phenomena associated with El Nino have strong impacts globally. The strong El Nino event during 1997∼98 was the most severe for the past 100 years. This paper examines sea surface temperature and 850 hPa wind fields during 1997∼98 to find the links between the super El Nino and the anomalous weather around the world. The 1997∼98 El Nino brought lots of rain to Taiwan in the spring time. However, the weather patterns seemed dramatically different from the previous one in 1982∼83. Strong southwesterly wind of 1997∼98 made the winter of Taiwan warmer and warm weather patterns stayed for a few months. |
