An Approach to Selection of Wind Tracers from Tropical Maritime Geosynchronous Satellite Cloud Imagery.
Abstract
Manual and automatic procedures for obtaining wind estimates from geosynchronous, dual-channel satellite cloud imagery are reviewed as background material for a proposed automatic system of extracting upper-level wind estimates from tropical maritime regions containing cirrus and low-level clouds. The manual procedures for satellite photointerpretation are subdivided into two stages: (1) determination of cloud genus based on textural and tonal characteristics and on known relationships between synoptic and cloud features, and (2) selection of cloud targets based on cloud genus, reliability of emissivity estimate for the target, and conformity of motion with advective mechanisms. A summary of the automatic operational system of NESS for low-level wind estimation and its extension to upper-level wind estimation is presented. A model for obtaining upper-level wind estimates is proposed.
