Tropical Cyclone test case: Edouard (2014) ATM 419 Spring 2016 Fovell 1
New for this experiment TC (tropical cyclone) test case is Edouard (2014), an Atlantic hurricane that reached Category 3 intensity WRF compiled with vortex-following nest Use available simple mixed-layer ocean model Use available TC-specific surface flux revisions Using TC bogus software to remove, revise a tropical cyclone See TC_experiment_details.docx for specific tasks and instructions 2

New additions to namelist.input sf_ocean_physics = 1, isftcflx = 2, control_file has been revised to add these new 2D fields, from the ocean model: TML ! OCEAN MIXED-LAYER TEMPERATURE T0ML ! INITIAL OCEAN MIXED-LAYER TEMPERATURE HML ! OCEAN MIXED-LAYER DEPTH H0ML ! INITIAL OCEAN MIXED-LAYER DEPTH HUML ! OCEAN MIXED-LAYER DEPTH * U-CURRENT HVML ! OCEAN MIXED-LAYER DEPTH * V-CURRENT TMOML ! OCEAN LAYER MEAN TEMPERATURE 5
RUN01 (1-domain only) Follow script instructions for executing geogrid, ungrib, and metgrid Inspect max and min MAPFAC_M Follow WRF instructions Make GrADS output from wrfinput_d01file wrfout_d01files 6
D1 slp field from wrfinput_d01 shown set cint 4 d slvl 7
open RUN01_D1 open RUN02_D1 tracker_wind.gs 1 2 set dfile 2 tracker_wind.gs 2 3 10
RUN02: 2-domain run See script instructions max_dom = 2, rerun real and wrf jobs Create GrADS output from D1 (via control_file.2D) and D2 (via control_file.domain2) Verify D2 is not fixed in space, and issues with respect to nest translation Compare TC track with RUN01 (see previous slide) 11
