北大西洋海温异常影响中东急流的观测分析和数值试验
OBSERVED AND SIMULATED INFLUENCE OF SSTA IN NORTH ATLANTIC OCEAN ON MIDDLE EAST JET STREAM
摘要
Abstract
By using NOAA Extended Reconstructed Sea Surface Temperature (ERSST) data from 1968 to 2009, the monthly NCEP/NCAR reanalysis data from 1968 to 2009, and NCAR CAM3 model, this paper studied the influence of sea surface temperature anomaly (SSTA) in North Atlantic Ocean in the preceding December on the Middle East jet stream (MEJS) in January. The observed and simulated results show that there is an obvious response of January MEJS anomaly to the SSTA in the key region of North Atlantic Ocean in the preceding December. When the SSTA is positive (negative), the MEJS will become weaker (stronger) in January. The response of general circulation anomaly to the SSTA in the preceding December can propagate to downstream regions, which induces the MEJS anomaly in January.关键词
