Group meeting 05.20.2013

“What if my house is hit by a meteorite?” Chelyabinsk, Russia: Feb. 15, 2013 “Blue ice” FAA: planes do not dump waste Leaks in holding tank RARE Homeowners Policies Standard grades HO-1, HO-2, HO-3 HO-2 covers 16 perils including “falling objects” HO-3 covers everything except a few provisions (i.e. earth movement, nuclear hazard, intentional loss, etc.) Renters Insurance Policies HO-4 covers 16 perils including “falling objects” Integrated energy released from explosion 33x (500 kilotons) Hiroshima, Japan (1945) atomic bomb Damage estimated at $33 Million 1200 people injured 4000 buildings damaged 100,000 homeowners effected Chino California in 2006.

What has been… COAMPS-TC v4.3.2 TCv1.0.0 Modified run scripts/namelists Tested example data for Hurricane Sandy (2012) Updated COAMPS v4.3.2 TCv1.0.0 for EnKF update Included EnKF perturbations Generated boundary conditions for WRF and COAMPS from GFS Obtained GFS data Kept in native grb2 format Used +/- 60 days 48h-24h GFS forecasts to generate perturbations* Built library for random sampling Cohesive perturbations between COAMPS and WRF * Dr. Jeff Whitaker’s GFS-EnKF Hybrid

What is… TACC Stampede: Testing COAMPS-EnKF code modification Run COAMPS v4.3.2 TCv1.0.0, COAMPS-EnKF, COAMPS IC/BC programs Run WRF-PSU-EnKF Focusing on Karl (2010) ensemble Testing COAMPS-EnKF code modification P-3 update Currently: code runs, assimilates observations, and results are within the “ballpark” Verify results against PSU-WRF-EnKF Technical English Exam

What will be… Set-up and run WRF-EnKF and COAMPS-EnKF experiments Hurricane Karl (2010) As close as possible: physics, dynamics, horizontal/vertical grid, domains, etc. Focus on initial times: 09/12: 00Z/12Z 09/13: 00Z/12Z Tropical cyclone vortex structure analysis: Similar to Aksoy et al. 2012, Aksoy 2013

What will be…continued Candidacy Exam: Beginning of August P-3 observation modification? Coplane “dual-Doppler” observation generation
