你要做敏感实验吗?
不需要做的话,上nudging.
我有一套之前做芝加哥降水时候用的,你可以试试,不打包票
&fdda
grid_fdda = 2,
gfdda_inname = "wrffdda_d<domain>",
gfdda_interval_m = 360,
gfdda_end_h = 72,
io_form_gfdda = 2,
fgdt = 3,
fgdtzero = 1, 1,
guv = 0.0003, 0.0003, ! nudging coefficient for u and v (sec-1)
if_no_pbl_nudging_uv = 1, 1, ! 1= no nudging of uv in the pbl, 0= nudging in the pbl
if_no_pbl_nudging_t = 1, 1, ! 1= no nudging of t in the pbl, 0= nudging in the pbl
if_no_pbl_nudging_ph = 1, 1, ! 1= no nudging of ph in the pbl, 0= nudging in the pbl
if_zfac_uv = 1, 1, ! 0= nudge uv in all layers, 1= limit nudging to levels above k_zfac_uv
k_zfac_uv = 10, ! 0= model level below which nudging is switched off for uv
dk_zfac_uv = 1, 5, ! depth in k between k
xwavenum = 3, ! top wave number to nudge in x direction
ywavenum = 3, ! top wave number to nudge in y direction
