Synthetic Imagery in Forecasting Orographic Cirrus

Instructors:

Topic:

Satellite Proving Ground

Developed:

2011

Introduction


Synthetic imagery analysis in forecasting orographic cirrus (lee wave clouds) has advantages:

  • Orographic cirrus is more readily identified compared to looking at model output fields, such as relative humidity over a layer.
  • Increased temporal resolution – hourly rather than model output times (NAM – 3 hourly ; GFS – 6 hourly)
  • Best approach is to blend synthetic imagery (WRF-ARW, CRAS, etc.) with model output fields from multiple operational models. This method combines a visual way of identifying orographic cirrus with an ensemble approach of looking at multiple models.

This is an experimental GOES-R Proving Ground Product designed to foster GOES-R readiness.

Training Session Options


NOAA/NWS students – to begin the training, use the web-based video, YouTube video, or audio playback options below (if present for this session). Certificates of completion for NOAA/NWS employees can be obtained by accessing the session via the Commerce Learn Center

  1. Audio playback (recommended for low-bandwidth users) – This is an audio playback version in the form of a downloadable VISITview and can be taken at anytime.

    Create a directory to download the audio playback file (195 MB) from the following link: http://rammb.cira.colostate.edu/training/visit/training_sessions/synthetic_imagery_in_forecasting_orographic_cirrus/synthetic_imagery_in_forecasting_orographic_cirrus_audio.exe

    After extracting the files into that directory click on either the visitplay.bat or visitauto.bat file to start the lesson. If both files are present, use visitauto.bat

  2. YouTube video:
