BOMEX

Barbados Oceanographic and Meteorological Experiment

Large eddy simulation of a cloud street at summer trade wind conditions over Barbados. Data initialization from radiosonde profile at 2013-06-22 00:30 UTC.
This movie covers a time span between 00:00 and 24:00 local time.

Visualization:
- 75 km × 75 km × 6 km domain part is shown
- 0.1 g/kg cloud water mixing ratio isosurfaces (white)
- 0.1 g/kg rain water mixing ratio isosurfaces (blue)
- temperature field at lowest model layer
- relative humidity field at western lateral boundary
- vertical extent of the simulation domain is stretched by a factor of 5 for a better view

Domain structure
- 110 km × 110 km × 6 km with 256 × 256 × 38 grid points
- vertical levels: Δz = 50 m, 100 m, 250 m up to z = 500 m, 1500 m, 4000 m, respectively
