Subtract glider descent rate to get average vario reading for cloudless thermals. Updraft strengths will be stronger than this forecast if convective clouds are present, since cloud condensation adds buoyancy aloft (i.e. this negects \"cloudsuck\"). W* depends upon both the surface heating and the BL depth.

BLIPMAP stands for "Boundary Layer Information Prediction MAP" -- a model for soaring weather forecast. It has been developed by Dr. John W. (Jack) Glendening ("DrJack"), who is meteorologist and sailplane pilot himself. More information on the meteorological model can be found on DrJack's RASP website. There you also find a discussion forum for questions about the model or problems with the forecast.
