4/3 km Domain Pushed South to Salem

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.

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

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.
