EMC/HPC/MPC/NCO/CPC synergy meeting highlights 10/29/01

This meeting was led by Peter Manousos and followed a generic agenda denoted by the subtitles below. Attendees included Hua-Lu Pan, Pete Caplan, Steve Tracton, John Ward, Jun-Du, Zoltan Toth, Dave Reynolds, Rivin Illya Rivin, Bill Bua, Jeff Borroughs, Ed Danaher, and Keith Brill.


John Ward reported that the IBM SP was very stable in Oct (backup tests have gone fine since the upgrade of the SP). No further upgrades are scheduled until System 9 replaces the current SP (targeted to begin July of 2002). Nov 6th will mark when the Climate Model becomes operational. Eta-12km still slated to go operational Nov 27. The 20km RUC's targeted implementation of Jan 2002 has now been delayed indefinitely.

2. Notes from EMC

a. Global Modeling Group: Hua-Lu reported testing continues on the T254 resolution MRF (output available as MRFx). Testing should be completed by sometime in December. The next upgrade to the Global Model will include T254 resolution out to 84 hours, then T170 out to 7.5 days, and then T126 out to day 16.

b. Mesoscale Modeling Group: Geoff Dimego was out sick so no report (see notes from IBM SP section on Eta-12 and RUC-20 status).

c. Global ensembles : Zoltan Toth reiterated what was reported last meeting (details on the parallel version of the Global Ensembles once per day with 10 members and at T126 resolution out to 7.5 days, planned combination of ECMWF, Canadian, and NCEP global ensembles to provide NCEP Centers with a multi-center ensemble prediction system product suite).

d. Short range ensembles (SREF): Jun Du reported that precip type output is available on SREF web page. Conditional probabilities of precip type and amount will also be posted on the web in support of the NWS Winter Weather Experiment with NCEP EMC, HPC, and some ER WFOs. A reliability issue with the web-based products which recently arose has been solved. The ensembles will be started from the 3-hour Eta forecast rather than EDAS if the EDAS is not available.

e. Marine Modeling and Analysis Branch (MMAB) - A 4 slide intro/presentation was provided by Illya Rivin describing primary aspects of the (Coastal Ocean Forecast System (COFS) model. This model is running in parallel once a day (00Z) out to 48 hours providing output of Sea Surface Temps, Sea Surface Heights, and location of the north wall of the Gulf Stream. Output is available on the web at http://polar.wwb.noaa.gov/cofs/. COFS is expected to become operational sometime in March 2002. Larry Burroughs reported that the ice analysis for the northern and southern hemisphere based on the SSMI 25km grid will go down to 12.5 km. The global analysis is currently a half x half degree grid and will go down to an eighth degree grid. The Hurricane Wave model will ingest data from GFDL by the start of next Tropical Season. By late July 2002, west coast output will be available on web on a .25 x .25 degree grid from 2 degrees N to 50 N and out past the Hawaiian Islands.

3. Input to EMC from Operational Centers - No items to report.

4. Next Meeting Proposed Monday November 26th at noon in room 209.
