The rising or falling trend of the sea level along the coasts of East Asia is estimated by different computational methods based on the sea level data of long time series collected from 45 tide gauge stations there.The results show that the relative sea level,on the average,is rising along the entire coast of East Asia from the early 1950s to the early 1990s.The regional change of sea level rise or fall.is greater.The sea level along the coast of China,except for Shandong Peninsula, is rising;the sea level along the coasts of the southern Japanese Islands and southern Korean Peninsula estimated by several methods is mostly rising,but rising rate is very small.The difference between the results estimated in this study and the corresponding results by Barnett along the coast of East Asia is significant.This is mainly because the number of the stations selected by Barnett is relatively small and the selected stations are concentrated at the southern and northern ends of the region, without data for the middle of the region.The effects of the estimating methods are minor.

根据东亚沿岸45个水位观测站的长序列水位资料,用不同的计算区域平均海平面升降的方法,估计了该区海平面升降趋势。结果表明,从本世纪50年代初至90年代初,整个海区平均而言海平面呈上升趋势。海平面升降的区域性变化较大:中国沿岸除山东半岛外,其他海区平均是上升的,在日本群岛南部和朝鲜半岛南部沿岸,由几种方法得出的结果多数是上升的,但上升幅度很小。本文对东亚沿岸海平面升降的估计结果与Barnett的相应估计差别较大,其主要原因是Barnett选站较少,且选的站集中在该区南北两端,中间部分无资料;估计方法虽有影响,但属次要的。

Time series analysis is conducted on sea surface air temperature, water temperature, air pressure and wind speed on COADS data for 4°×8°squares in the Pacific Ocean during 1950-1992. The analytical results of the rates of the rise show that the sea surface air temperature and water temperature are rising in the Pacific Ocean with rise rates of 0. 0063℃ and 0. 0026℃/yr respectively. The trends have both a high-value zone of rising rates in the equatorial Pacific and a low-value zone of falling rates...

Time series analysis is conducted on sea surface air temperature, water temperature, air pressure and wind speed on COADS data for 4°×8°squares in the Pacific Ocean during 1950-1992. The analytical results of the rates of the rise show that the sea surface air temperature and water temperature are rising in the Pacific Ocean with rise rates of 0. 0063℃ and 0. 0026℃/yr respectively. The trends have both a high-value zone of rising rates in the equatorial Pacific and a low-value zone of falling rates in the vast sea area of Northwest Pacific, north of the northern East China Sea. The regional distribution feature of rise or fall of air temperature and water temperature is related to the variation trend of reinforcement and weakening of the components of vector wind. At the same time,the influences of the rise or fall trends of the above mentioned sea surface ele-ments in the Pacific upon the rise or fall of sea level in different sea areas are also discussed. It is proposed that for predicting the variation trend of sea level off China and Japan in future decades,the forecasting model based on the Pacific or global sea level rise trend is adopted while considering the local changes in the sea level of the particular sea area.

对COADS资料中1950-1992年太平洋4°×8°方区的海水表层温度及海面气温、气压、风速序列数据,进行了时间序列分析。分析结果表明:太平洋海表气温和水温年上升率分别为0.0063℃·a(-1)和0.0026℃·a(-1)。两者的变化趋势在赤道太平洋都有一个年上升率高值区;而在东海以北的西北太平洋广大海区,都有一个年下降率的低值区。西太平洋海面气压呈上升趋势,东太平洋则相反。气温和水温的升降区域分布特征与风速分量增强和减弱的变化趋势有关。文章还指出,中国和日本沿岸今后几十年海平面变化趋势的预测模式,应以太平洋或全球海平面上升趋势的预测为基础,加上本海区海平面的局地变化订正。

On the basis of the analytical results of the period components of monthly mean sea level of 236 stationsin the Pacific, the period components plus linear trend are ed to fit the monthly mean sea level series. The statisticalresults of linear trend Coefficients of these stations indicate that, if the abnormal values of sea-level rise and fall are neglected, the average rise rate of relative sea level in the Pacific is 1. 16 mm/a.

On the basis of the analytical results of the period components of monthly mean sea level of 236 stationsin the Pacific, the period components plus linear trend are ed to fit the monthly mean sea level series. The statisticalresults of linear trend Coefficients of these stations indicate that, if the abnormal values of sea-level rise and fall are neglected, the average rise rate of relative sea level in the Pacific is 1. 16 mm/a. Affected by nonuniformity Of land subsidence and other factors, the regional change of relative sea level rise or fall in the Pacific is greater. In the light of thepositive or negative values of linear trend coefficients as well as the geographical position of the sea area, zoning is madeof the sea level rise or fall in the Pacific including the coastal areas of China and Southeast Asia to obtain the averagerate of rise or fall in each sea area. The rise or fall trends of relative sea level obtained for the entire Pacific Ocean,west coast of North America, the northern and central South America, the greater part of the tropical Pacific and thecoastal Islands of Japan are basically in keeping with the other relevant results. The regional average estimated result ofthe relative sea level in the coast of East Asia is on the rise while the estimated results provided by Barnett tend todrop; the main cause of this nonuniformity is the number of stations selected and the distributional density.
