Consortium Meeting
Feb 2, 2012
Hit Rates
Big Snowstorm Hi: 3-4x normal demand. Slowed down web server-new fixes for this
Second is Canadian (Toronto): Should I block
Data Rates: Will Stop Google
Hardware
• New, more powerful data server
• New internal web server
• Major internal improvements last week to
improve responsiveness on the web
• Let me know if there are any problems with
access.
Major Changes
• On October 17th, moved to the new domain
structure, with major expansion of 4/3 km
domain, and modest expansions on 12 and 4
km domains.
Before
After
Hardening the New System
• The new domains are now solid, and several tweaks to
the control scripts and model, and the experimental
language has been taken off of them on the web.
• Also “experimental” was taken off the extended run.
• New data storage array for SAGE.
• New department data server.
• New internal web server to reduce load
• Major improvements and fixes since snowstorm to
improve robustness under major loads.
Timing
• MM5-NAM to hour 72 by 7:05 am/pm PST
• WRF 36/12 to hour 84 by 9 am/pm PST 36/12
to hour 180 by 10 am/pm PST (runtime 2.25
hours)
• WRF 4-km to hour 84 by 9:10 am/pm PST
(runtime 1.5 hours)
• WRF 4/3 km to hour 48 by 2:30 pm/am PST
runtime 5.1 hours it can be done as early as
2:02 if there is no precip
Major Enhancements to Web Page and
New Products
• Consolidated 1 1/3 km domain Web page with
the rest of the domains .
Random Point Selection for All
Products Now Working for All Domains
New Products
• Added all air quality graphics for the 1 1/3 km
domain and fixed up labeling locations
Major Changes to Web Pages and
Products
• Added subdomains (zoomed in) for the 1 1/3 km domain
for wind speed.
• Added high-resolution roads, islands, coastlines, and
counties to our version of RIP. Using these on the most
zoomed-in domains.
• Added more snow graphics for the 1 1/3 km domain
• Added model snow for western Washington views of all
domains .
• Added pre-generated soundings, time-heights, and
meteograms for the 1 1/3 km domain.
• Nearly done fixing the meteograms for the MM5-NAM
(they're plotting locations based on the WRF-GFS domain
which is quite different).
What Else?
• What further changes and additions are
needed to graphics/products?
• Anything you think we can drop?
Verification Stats
No Drag Parameterization in 4/3 km
Maintain and Improve Ensemble
Systems
• UWME based on WRF
• EnKF based on WRF.
• More on these at next consortium meeting.
Next Steps
•
•
•
•
•
Evaluate adding additional levels in PBL..especially for 4/3 km
Addition changes/improvements to subgrid drag parameterization.
Test new PBL schemes
Test new WRF version 3.4 coming out next month.
Test new NOAA Land Surface Model (LSM) to see if surface
temperature biases are improved.
• Using LSM, allow snow to change during runs (not now).
• Improve products for EnKF system and complete rewrite of Phil’s
code.
• Consider driving the high-res system by the best ensemble member
of the ensemble mean.
The END
