A simplified diagnostic model of orographic rainfall for enhancing satellite-based rainfall estimates in data-poor regions
Christopher C. Funk, Joel C. Michaelsen
2004, Journal of Applied Meteorology (43) 1366-1378
An extension of Sinclair's diagnostic model of orographic precipitation (“VDEL”) is developed for use in data-poor regions to enhance rainfall estimates. This extension (VDELB) combines a 2D linearized internal gravity wave calculation with the dot product of the terrain gradient and surface wind to approximate terrain-induced vertical velocity profiles. Slope,...
