Improved Three Dimensional Nephanalysis Model

摘要

The AFGWC objective three-dimensional computer program (3DNEPH) produces high resolution, three-dimensional analyses of clouds in the atmosphere. A horizontal grid spacing of approximately 25 nautical miles is used. Analyses are made for 15 layers from the earth's surface to 55,000 feet MSL, with highest vertical resolution near the surface (150 feet depth for layer 1) and lowest vertical resolution at the top of the model (20,000 feet depth for layer 15). The program is a stream of individual processors. The improved program has added a processor to permit forecaster-prepared data to be used, a satellite infrared data processor, a forecast processor and a verification processor. The improved version also includes improvements to the other processors. A description of each major processor is included. Selected samples of displayed data are shown. (Author)
