Boundary Layer Information Prediction MAP

The Netherlands, North Belgium and Northwest Germany

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 and tomorrow starts at 00 UTC and for the day after
tomorrow at 06 UTC. For today and yesterday the results are available in 2
resolutions, 4 km ("coarse grid") and 1.3 km ("fine grid"). The area that's
computed using the fine grid is much smaller than the area that's computed
using the coarse grid. For tomorrow and the day after tomorrow, results are
only available using the coarse (4 km) grid.

The results are available
for today at 08:30 local time, for tomorrow at 09:30 and for the day after
tomorrow at 10:30 at the latest and depending on the weather sometimes up till
30 minutes earlier. 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 10:30 no results are available
for the day after 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
thishelps.
