  1. KMA report 31 October – 2 September 2011 Young-Youn Park Numerical Model Development Division, Korea Meteorological Administration

  2. KMA global ensemble: Changes

  3. TIGGE data • TIGGE data • Old EPS data: 16 Jan 2008 ~ 30 Nov2010 • No data since 1 Dec 2010 • because of network problem(too slow to ftp the new ensemble data ~ 64GB/day) • Tried two way: • To enhance N/W speed to ECMWF  recently succeed (80min/32GB)  under test • To send data to NCAR using LDM  difficulty in setting LDM • Changes in TIGGE data • Resolution: (Operation 0.5625deg, TIGGE 1.25 deg)  (0.5625, 0.375 deg) • Size: old 10GB/day  new 64GB/day(later 84GB/day) • Parameter • 8 P levels * 5 par + gph at 50 hPa(OK)  4 pars (no q) • 1 pt level (320K) * 1 par (pv) (X) OK • 2 pv level * 3 parameter (X) pt (no u, v) • Single level * 28 parameter (6 parameters)19 pars

  4. Other data • Cyclone data: ftp://cxml:cxml@210.107.255.35 • Not working after 30 Dec 2010 • Security issue with IT team • Will resume later … • Model description(metadata): ready to update • KMA’s verification statistics report(to LC on EPS verification): • Deterministic score: 200901- (NH), 201103-(TR, SH) • CRPS: under checking if KMA use the same method as instructed • Reliability table parameters: 200901- (NH), 201103-(TR, SH), T850, Z500, PMSL only
