北太平洋风场变化对东亚陆架海SST的影响
Pacific Wind Change and Its Influence on SST in East Asia Marginal Sea
摘要
Abstract
Pacific internal climate change is closely related to changes of the marine environment in East Asia marginal sea. Oaflux and NCEP reanalysis data were used to study the wind spatial and temporal variation within the North Pacific. Correlation analyses between the wind speed anomalies in North Pacific and the times series of SST anomaly in East Asia marginal sea were made to find out the wind key region influencing on East Asia marginal sea signally. The results showed that, correlation coefficient between the SSTA in East Asia marginal sea and the PDO index with a zero-lag is close to 0, which showed that abnormal signals within North Pacific affected SST in East Asia marginal sea only by baroclinic Rossby waves adjustments, not the barotropic change. The wind key region A and B over North Pacific influenced on East Asia marginal sea signally, and during 1958-2010, wind speed in the two key regions increased abnormally, meanwhile,they were controlled by the curl dipole, abnormal negative wind stress curl separately, so the abnormal signals propagated from the Middle and East Pacific to East Asia marginal sea, causing SST increased significantly, especially in the Kuroshio. Wind variations over the key region A, B leaded SST changes in East Asia marginal sea by 4a (7a), 4a separately, which were in consistent with the time needed of Rossby waves propagating from the middle, east ocean to the west or subtropical circulation adjustment by Rossby waves.关键词
