Weather Forecast Adjustment Using Model Output Cloud Fields and Digital Satellite Data.

摘要

The technique of using digital satellite data to monitor the accuracy of model output derived cloud fields is examined to determine its feasibility and practicability. Cloud fields are produced from ceiling and cloud amount forecasts based on Model Output Statistic equations. Their cloud fields are displayed on a coordinate system that is compatible with a corresponding display of digitized GOES satellite data. The model output cloud fields are displayed over a 12-hour forecast period to depict what the satellite cloud field should look like at some future time. The technique was found to be both feasible and easily adapted for use on an interactive display system. Simultaneous display of the forecast and observed cloud fields appear to be a useful tool to aid in short range forecasting decisions and for monitoring the existing forecast. (Author)
