Title:
METHOD FOR ASSIMILATING RADAR MELTING LAYER ELEVATION DATA ON BASIS OF ULTRA-SHORT FORECAST MODEL, AND RECORDING MEDIUM AND APPARATUS FOR PERFORMING SAME
Document Type and Number:
WIPO Patent Application WO/2020/096141
Kind Code:
A1
Abstract:
Disclosed are a method for assimilating radar melting layer elevation data on the basis of an ultra-short forecast model, and a recording medium and an apparatus for performing same. The method for assimilating radar melting layer elevation data on the basis of an ultra-short forecast model, comprises: a step of collecting radar observation data from a meteorological radar system to produce observation data including the altitude and the temperature of a melting layer; a step of preprocessing the observation data to be applicable for data assimilation; a step of calculating an analysis increment for the observation data by applying a three-dimensional variable data assimilation method between background fields of an ultra-short forecast model; and a step of generating an initial field of the ultra-short forecast model using the analysis increment, and predicting precipitation.
