Preliminary Study of the Atmospheric Circulation During the Period Preceding the 1972-73 El Nino. (A NORPAX Contribution),
Abstract
The National Environmental Satellite Service (NESS) and the National Oceanic and Atmospheric Administration (NOAA) have jointly started issuing monthly averaged maps of streamfunctions at 700 mb and 200 mb elevation covering the global belt from 48 degrees N to 48 degrees S. The streamfunctions represent only the nondivergent part of the air flow. To obtain a further approximation to the real air motion, rather weak fields of convergent motion can be assumed to exist where the streamfunction showed cyclonic vorticity and divergent motion where the streamfunction is anticyclonic. With this in mind, one can explore the atmospheric circulation by studying the streamfunction maps, as demonstrated in the report.
