  1. Consortium MeetingFeb 2, 2012

  2. Hit Rates Big Snowstorm Hi: 3-4x normal demand. Slowed down web server-new fixes for this

  3. Second is Canadian (Toronto): Should I block

  4. Data Rates: Will Stop Google

  5. 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.

  6. 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.

  7. Before

  8. After

  9. 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.

  10. 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

  11. Major Enhancements to Web Page and New Products • Consolidated 1 1/3 km domain Web page with the rest of the domains .

  12. Random Point Selection for All Products Now Working for All Domains

  13. New Products • Added all air quality graphics for the 1 1/3 km domain and fixed up labeling locations

  14. 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).

  15. What Else? • What further changes and additions are needed to graphics/products? • Anything you think we can drop?

  16. Verification Stats

  17. No Drag Parameterization in 4/3 km

  18. Maintain and Improve Ensemble Systems • UWME based on WRF • EnKF based on WRF. • More on these at next consortium meeting.

  19. 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.

  20. The END
