RASP 4Km resolution for Bir-Billing area, indian Himalaya : mesoscale weather forecast model for glider pilots     

RASP = Regional Atmospheric Soaring Prediction.    BL = (convective) Boundary Layer.    Z = GMT = UTC = Universal Time (Greenwich time).    IST = Indian Standard Time = Z+5:30  =>  6Z = 11:30 IST / 9Z = 14:30 IST

Developped by Dr. John W. (Jack) Glendening, meteorologist - Implemented by J. Oberson (soaringmeteo.ch) for Bir-Billing area (march 2010). It is not guarantee that this model will be operational every day. The model software runs on a quadriprocessor 2.83GHz computer on Ubuntu-Linux environment and uses the US macroscale GFS model analysis as start reference data. I take no responsibility in the event of flight mishaps due to a wrong interpretation of these free predictions ! It needs about 45 mn (for each forecast day) to carry out all the processes until the display on the website. Remarks, bugs reports, suggestions are welcome : info at soaringmeteo dot ch
