摘要

本文使用美國海洋暨大氣總署。可ational Oceanic and Atmospheric Administration, NOAA)國家環境預報中心(National Centers for Environmental Prediction, NCEP)的海面溫度(Sea Surface Temperature, SST)資料，以線性迴歸分析其變化趨勢。1982至2001年的全球海面溫度每十年上升約0.11±0.03℃。在季節性的變化上，7~9月的增溫現象比12~2月為強烈。全球的海面溫度變化趨勢分佈，除了少數幾個區域是呈現減溫現象外(如赤道太平洋及南太平洋高緯度區) ，絕大部份是呈現增溫的現象。另外，北半球及南半球的海面溫度變化趨勢分別每十年上升17±0.04℃及0.06±0.03℃而三大洋的增溫現象則以北大西洋最為強烈。

Sea Surface Temperature (SST) data from 1982 to 2001 obtained from National Centers for Environmental Prediction (NCEP) at National Oceanic and Atmospheric Administration (NOAA) were used to calculate global and regional SST trends by linear regression. The global SST trend is 0.11±0.03 decade during 1982-2001. In seasonal analysis, the warming trend is stronger in boreal summer than that in boreal winter. The SST trends in most areas are positive, except for some regions where are negative, e.g. equator Pacific and high latitude in the southern Pacific. The SST trends in the northern hemisphere and the southern hemisphere are 0.17±0.04 decade and 0.06±0.03 decade, respectively. The highest warming trend is in the northern Atlantic Ocean.
