WINDSOR - LAPS / STMAS Page
Welcome to our ESRL study of the Windsor, CO tornado of May 22, 2008.
Compare the accuracy of WRF forecasts initialized at different times to the
Windsor tornado event (around 1800 UTC May 22).
Make dprog/dt animations to illustrate how the forecasts converge on the actual weather, as depicted in the analyses.
Verification will be conducted of fields such as radar reflectivity and wind.
For radar reflectivity in particular, we have some quantitative verification
software we can easily use. Also, it will be essential to validate the model
analyses and forecasts against the special observations
see Steve Koch's list
). This is probably the most important single scientific contribution that this study will make, given the uniqueness of these data for a study such as this.
Compare the verification results using both LAPS and STMAS as analysis
There are several reasons to spend time looking at this, including the internal
need we have at GSD
to better understand the performance of the two analysis options, but also because we are advocating a process for replacing LAPS by STMAS in an operational framework supportive of the Forecast Offices and we need to make a much stronger case for doing that.
LAPS/STMAS will be run with both routinely archived Mass Store
observational data plus as many "special" datasets as we can gather and read into the analyses.
WRF forecasts and LAPS/STMAS analyses will be run on both a revised
domain at a resolution of ~5km (as we discussed last time), with an inner domain at 1-1.5km.
