MODEL
5-layer slab scheme, set to land point and
permanent ice; if water point and Noah
scheme, set to land point, permanent ice,
set temps from 3 m to surface, and set
smois and sh2o
sst_update option to use time-varying SST, seaice,
vegetation fraction, and albedo during a
model simulation (set before running real)
0 no SST update
1 real.exe will create wrflowinp_d01 file at
the same time interval as the available
input data. To use it in wrf.exe, add
auxinput4_inname =
"wrflowinp_d",
auxinput4_interval in namelist section
&time_control
tmn_update 1 update deep layer soil temperature, useful
for long simulations
lagday 150 days over which tmn is computed using
skin temperature
sst_skin 1 calculate skin SST, useful for long
simulations
bucket_mm -1. bucket reset values for water accumulation
(unit in mm), useful for long simulations; -
1 = inactive
bucket_j -1. bucket reset value for energy
accumulations (unit in Joules) useful for
long simulations; -1 = inactive
slope_rad (max_dom) 0 slope effects for ra_sw_physics=1 (1=on,
0=off)
topo_shading (max_dom)0 neighboring-point shadow effects for
ra_sw_physics=1 (1=on, 0=off)
shadlen 25000. max shadow length in meters for
topo_shading = 1
omlcall 0 simple ocean mixed layer model (1=on,
0=off), only works with
sf_surface_physics = 1
oml_hml0 50. initial ocean mixed layer depth (m),
constant everywhere
oml_gamma 0.14 lapse rate in deep water for oml (K m-1)
isftcflx 0 alternative Ck, Cd for tropical storm
application. (1=on, 0=off)
fractional_seaice 0. treat seaice as fractional field (1) or ice/no
