Date: Wed, 27 Oct 2004 07:36:25 -0600 From: Robert Rozumalski Subject: Announcement: National WES case study #18 now available Greetings All, I am pleased to announce new addition to the National Case Study Library: http://strc.comet.ucar.edu/csl National WES case study #18 Title : Forecasting a Frontogenetically Forced Snow Band Author : Michael Evans TRAINING OBJECTIVES On successful completion of this simulation, the trainee should be able to: * Understand the effect of frontogenesis in forcing upward motion and precipitation * Understand the relationship between frontogenesis, atmospheric stability, and the potential for banded precipitation * Demonstrate how to use NCEP-generated graphics from the Short Range Ensemble Forecasts (SREFs) to check confidence in the operational model solutions * Understand the limitations of the SREFs * Understand how errors in model initial temperature fields can lead to frontogenesis and QPF forecast errors * Demonstrate how to adjust model guidance based on the latest observations * Demonstrate how knowledge of the anticipated thermodynamic profile of the atmosphere can be used to adjust snow to liquid ratios INTRODUCTION This simulation guide details a winter storm that occurred across central New York and northeast Pennsylvania on 30 March 2003. The primary objective of this simulation is to introduce forecasting techniques for bands of frontogenetically forced moderate-to-heavy snow. The type of simulation utilized for this training exercise is an interval-based simulation. Case #18 is available on DVD along with a companion simulation guide from the SOO/STRC National Case Study Library: http://strc.comet.ucar.edu/csl Let me know if you have any questions.
