The utilization of statistical properties of satellite-derived atmospheric motion vectors to derive quality indicators

From: Weather and Forecasting | Date: December 1, 1998| Author: | Copyright information

ABSTRACT

The extraction of atmospheric motion vectors (AMVs) from cloud and moisture features from successive geostationary satellite images is an established and important data source for numerical weather prediction (NWP). So far the extraction of AMVs has been confined to the main synoptic times only, which grossly underutilizes the potential of these satellite-derived data. The advent of four-dimensional variational assimilation techniques provides the opportunity to utilize data derived at asynoptic times. This will enhance the capabilities of geostationary satellite systems that can ...
