1800km Sierra Wave XC Flight Today

I've created an image loop (760KB) showing how the model thinks the
wave changed between 0800 and 1600 PST for this day, with images at 1
hour intervals (the first image is displayed for a longer interval to
indicate the start of the loop) at

It shows the wave falling apart at the end of the day.

PS in my last post the first link given was actually for 1600 PST
not 1300 PST as stated, so showed the wave when it was less coherent
than earlier in the day

It looks like the secondary/tertiary/5th6thary waves got more organized as
the primary weakened. A flatlander asks "is this common?"

You can see a high resolution, true color image of the same area he

http://rapidfire.sci.gsfc.nasa.gov/s...1.2005086.aqua

The 250 meter resolution image is large and may provide too much detail,
but the 1 km is about the same scale as the image Dr. Jack presents.
They look similar, but keep in mind the satellite image is a composite
using images spread over a couple hours.

Actually the 2km satellite resolution is most comparable since model
resolution (for the loop at least) is 4km. BTW, one thing to note is
that with complex terrain wave updrafts are not always simple parallel
lines as in ideal cases - see for example the updraft "Y" near Lake
Tahoe (lat=39,lon=-120) at 0800 PST.
