RASP 2Km resolution for the Jura mountain : mesoscale weather forecast model for glider pilots           

RASP = Regional Atmospheric Soaring Prediction.    BL = (convective) Boundary Layer.    Z = GMT = UTC = Universal Time (Greenwich time).    CET = Central European Time (winter) = Z+1.   CEST = Central European Summer Time = Z+2.

EVENING forecast for the next day and MORNING forecast for the current day at 09Z, 12Z and 15Z. Last forecast carried out on Wednesday 26 September 2012 at 17:20Z for Thursday 27 September 2012

Developped by Dr. John W. (Jack) Glendening, meteorologist - Implemented by J. Oberson and A.Hugonnaud for the Jura mountain (february 2011). It is not guarantee that this model will be operational every day. The model software runs on a quadriprocessor computer on Ubuntu-Linux 64bits environment and uses the US macroscale GFS model analysis as start reference data. We take no responsibility in the event of flight mishaps due to a wrong interpretation of these predictions ! It needs about two hours to carry out all the processes until the display on the website. Remarks, bugs reports, suggestions are welcome : alex at airfly dot ch
