Hit Rates: Canadians Sneaking Back In

Data Volume

4/3 km Domain Pushed South to Salem

New 1.3 km Domain Now Completely Stable Needed to use small damping of vertically propagating sound waves

Next Stage: Idaho Expansion We now have the processors (3 nodes-24 cores) provided by Idaho to push the domain eastward. Should have no impact on the 4/3 km run time, and other earlier runs will be faster. New processors are being tested now, could try expansion during the next few weeks.

Expansion

Even Bigger?

High-Resolution Snow Update Every Day

May 15

But then a problem appeared in 2-m temps—always near freezing over snow

After talking to WRF experts, who confirmed there is a problem with 2-m temp output, switched to lowest model level—roughly 19 m

Close to Fixing Other Problem: Streakiness (courtesy of Congressman W)

Profiler Data Versus Acars

Profilers and Vertically Pointing Radars

ACARS Soundings at SEA, PDX

Raising Model Top Can we raise it to 50 mb from the current value of 100 mb? Will reduce reflection of gravity waves from model top and recommended by WRF help.
