摘要

Subsynoptic convective areas are isloated, monitored and forecast through extrapolation and advection using McIDAS, (Man-Computer Interactive Data Access System), and interactive computer video-display system. Research on isolating the convective areas focuses on development of statistics using digital visual and IR GOES satellite data to delineate areal coverage and intensity. McIDAS algorithms have been developed to: (1) compute the brightness centroid; (2) form a best-fit ellipse to the region; and (3) compute areal average IR and normalized-visual brightness. Sequences of brightness centers and geometric outlines serve as input extrapolation routines to project system movement and change in area coverage and intensity. Research also has been initiated on using vertically-integrated wind fields to advect meteorological fields and disturbances. Preliminary results using these techniques for short-range forecast are presented.
