Consortium MeetingFeb 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.
