1. EMC hurricane-NMMB (HNMMB) development plan Targets: 2015 continue development/tests 2016 tests/parallel real-time run 2017 real-time run

2. TaskStatusLead/support Personnel NoteStart/Complete date Transition of HWRF physics suite to NMMB DoneWeiguo Lin … Update to 2015 hwrf version Need tests Update by June, 2015 HWRF nest motion algorithm to NMMB ShortlySam Weiguo … With some in-model diagnostic fields June/May to Sep, 2015 HWRF vortex initialization to NMMB almost Done Qingfu Lin… Need testsApril to June 2015 Ocean POM/HYCOM to NMMB ShortlyBin Dmitry Hyun-Sook Regional HycomPOM: April to Oct 2015 HYCOM: planned Ocean couplingShortlyDmitry Bin Zhan progress in nems’s NUOPC is slow. May need a hwrf- like coupler for use in a year April to Sep 2015 HWRF data assimilation PlannedMingjing, Jason Bin, Banglin GSI-EnKF ? Interface/data change April to Sep 2015 Post processing Graphics PlannedLin, Keqin Sam Weiguo.. now OK to use ncep-post,Sep to Oct, 2015 ScriptPlannedSam, Zhan Mingjing,Keqin HWRF-like Python scriptSep to Nov, 2015

3. Code management All source codes, scripts, utilities and libraries, etc. should be saved at EMC SVN repository (https://svnemc.ncep.noaa.gov/projects/hnmmb). Development will be conducted in “hnmmb/branches”. We already have a project in EMC SVN site. https://svnemc.ncep.noaa.gov/projects/hnmmb branches/ tags/ trunk/

4. Tentative structure of hnmmb/trunk: sorc/ EMCGSI/ vortex_init/ NMMB/ NPS/ nmmb-coupler/ pomtc/ hycom/ gfdl-vortextracker/ post/ util/ lib/ ush/ scripts/ graphics/ regression_tests/ Code management

5. Test plans Meaningful tests can start once the hwrf nest motion algorithm is ready in NMMB. When DA and ocean coupler not ready, we can insert HWRF vortex in the initial fields as an alternative and test phys and other configurations. Target: Preliminary retrospective tests start in August. 2015 Real-time demo in Aug (without expectation of DA and ocean) Full system tests are expected to start in Dec. 2015
