RASP BLIPMAPS for North- and Central France

Regional Atmospheric Soaring Prediction
Boundary Layer Information Prediction MAP
North- and Central France

The atmospheric Boundary Layer (BL) is the vertical region above the surface within which air has been mixed by thermal or windshear eddies, i.e. the region where gliders, hanggliders and paragliders normally fly. The RASP BLIPMAP model is developed by Dr. John W. (Jack) Glendening and is a WRF model specifically adapted for these gliders. The basic parameters are described here and all parameters here. A description of all parameters in German can be found here. If you have any remarks or questions, please email rasp@blipmaps.nl. The model for today starts at 00 UTC and for tomorrow at 12 UTC. Both have a resolution of 4 km. The results are available, depending on the complexity of the weather, for today at around 08:30 local time and for tomorrow at around 20:30. Animations have only been made for those parameters of which the legenda doesn't change througout the day. After midnight all results are copied to one day earlier. Due to this until 20:30 no results are available for tomorrow. How actual the forecast is can be derived from the number of hours that is noted in each picture before the text "hrFcst@". This is the difference between the model starttime and the time at which the forecast is valid. If you have difficulties distinguishing colors then this helps.
