Water Vapor Imagery and PV Analysis

Introduction

This intermediate-level VISIT teletraining lesson (a follow-on to the introductory-level Water Vapor Channel Satellite Imagery lesson) will highlight water vapor satellite signatures associated with dynamical structures, using the framework of potential vorticity (PV) thinking, PV anomalies, and the dynamic tropopause. The use of water vapor channel satellite imagery and GOES sounder total column ozone imagery (as well as "synthetic water vapor imagery" forecasts from the CRAS model) to assess NWP performance will also be discussed.

Prerequisites

This is an intermediate course.

Training Session Options

  1. Live VISIT teletraining (with an instructor leading the session). Check the VISIT Training Calendar to signup for teletraining. The session will last 90 minutes. This teletraining session uses the VISITview software, where a Windows PC with an Internet connection is needed.

    Please follow the teletraining installation instructions to install the session

  2. VISITview playback without Audio - You may step through the VISITview file on your own to view the presentation. If talking points are available, you may use these in tandem with going through the slides.

    Create a directory to download the playback file from the following site: http://rammb.cira.colostate.edu/training/visit/training_sessions/water_vapor_imagery_and_pv_analysis/water_vapor_imagery_and_pv_analysis.exe

    After extracting the files into that directory click on the visitlocal.bat file to start the lesson. Advance slides on your own using the navigation controls (i.e., the Next button will advance to the next slide)
