- Animation
of cloud top heights from a BOMEX trade cumulus simulation on an
approximately 25 by 25 km domain using 256x256x72 gridpoints and a 100
m horizontal and 50 m vertical grid spacing, made by Dave Stevens of
Lawrence Berkeley Labs. Blue cloudtops are at 600 m, just above the
subcloud lifted condensation level, and red corresponds to about 2 km
cloud tops. Note range of cloud top heights.

Presentations
from Lake Arrowhead Workshop on the Planetary Boundary Layer, 14-16
June 2005. Many GCSS BLCWG participants attended this excellent
workshop, though it was not formally a GCSS event.
