This paper is concerned with the comparison of four different non-divergent wind fields obtained from a single geopotential height field over a dense data area. After developing the divergence equation of the non-divergent stream function, four different stream functions are obtained by modification and/or deletion from the basic equation. Isotach patterns for each stream function are computed. A comparison of the four stream function patterns and their corresponding isotach patterns is made. Two of the stream functions are used to obtain the non-divergent wind field for the intitial wind conditions in a primitive equation model developed by Krishnamurti. Two 36-hour forecasts are made. A comparison of the firecasts is made at three-hour intervals up to 24 hours and at 36 hours. Both forecasts are compared to the reported winds at 12-hour intervals

An objective technique for estimating large-scale flow pattern in the tropical upper troposphere from digitized cloud brightness data. Jacobs, Frederick T. (Monterey, California. Naval Postgraduate School, 1974);An objective technique is proposed to use digitized satellite cloud brightness data to estimate large-scale flow patterns over data-void tropical regions. It is basically a diagnostic model which assumes: 1) area-averaged cloud ...
