The goal of this session is to demonstrate how Infrared satellite image temperature patterns on thunderstorm tops correspond to the environment. This session will introduce three classes of signatures. The enhanced-V will be shown to belong to Class II. By dividing thunderstorm signatures into three classes the student will be better able to locate storm updrafts in IR satellite imagery.
This session is designed to accompany IC 9.1.2: The Enhanced-V: A Satellite Severe Storm Signature also taught via teletraining and known as the Integrated Sensor Training PCU 9.2.1 Enhanced-V teletraining session. The material is derived from the following papers and from Jim LaDue’s “Multispectral Analysis of Convection” COMET SatMet Course presentation The following materials are also recommended:
