DIAGNOSTIC ANALYSIS OF MEAN MERIDIONAL CIRCULATION ANOMALY IN LOW LATITUDES IN RELATION TO ZONAL MEAN SST ANOMALY

  • Nanjing Institute of Meteorology


    Abstract
  • The mass stream function of zonal mean meridional circulation is calculated in terms of NCEP/NCAR monthly meridional wind speed and vertical velocity, and the climatic and anomalous features of zonal mean SST and meridional circulation are investigated. Results show that (1) a joint ascending branch of Northern and Southern Hadley circulation is on the side of the summer hemisphere near the equator ,being well consistent with the extremum of [SST ],and a strong descending by the winter-hemispheric side.(2)El Nino-related [SST] in low latitudes is an important outer-forcing source for anomaly meridional circulation, which is affected by seasonal variation of basic airflow and [SST ], and interannual and interdecadal changes of [SST] .
