摘要

This memorandum presents a technique for estimating precipitation from extratropical cyclones using visible and infrared geostationary satellite imagery, radar data and conventional data. Extratropical cyclone systems were divided into five categories. For each category, schematics of evolution of cloud patterns associated with moderate to heavy precipitation were developed. Using the schematics along with radar and conventional data, precipitation estimates (rainfall and snowfall) and short range forecasts were produced. Verification was done on the estimates and forecasts produced from September 1982 through April 1983.
