prep_chem_sources.inp中如下变量修改有疑问,不太清楚该怎么设置,目前我对它们的设置如下:
nlat=320, ! if gg (only global grid)
lon_beg = -180., ! (-180.:+180.) long-begin of the output file
lat_beg = -90., ! ( -90.:+90. ) lat -begin of the output file
delta_lon = 360, ! total long extension of the domain (360 for global)
delta_lat = 180, ! total lat extension of the domain (180 for global)
NGRIDS = 2, ! Number of grids to run
NNXP = 120,22,86,46, ! Number of x gridpoints
NNYP =71,19,74,46, ! Number of y gridpoints
NXTNEST = 0,1,2,3, ! Grid number which is the next coarser grid
DELTAX = 18000.,
DELTAY = 18000.,! X and Y grid spacing
! Nest ratios between this grid and the next coarser grid.
NSTRATX = 1,3,3,4, ! x-direction
NSTRATY = 1,3,3,4, ! y-direction
NINEST = 1,57,0,0, ! Grid point on the next coarser
NJNEST = 1,33,0,0, ! nest where the lower southwest
POLELAT = 36.05, !-89.99, ! If polar, latitude/longitude of pole point
POLELON = 103.88, ! If lambert, lat/lon of grid origin (x=y=0.)
STDLAT1 =30., ! If polar for BRAMS, use 90.0 in STDLAT2
STDLAT2 = 40., ! If lambert, standard latitudes of projection
!(truelat2/truelat1 from namelist.wps, STDLAT1 < STDLAT2)
! If mercator STDLAT1 = 1st true latitude
CENTLAT = 36.05,!-89.99, -23., 27.5, 27.5,
CENTLON = 103.88, -46.,-80.5, -80.5,
我要模拟的是兰州地区,两层嵌套,中心经纬度为36.05N,103.88E。namelist.input中有关变量设置如下:
max_dom = 2,
e_we =120,22,
e_sn =71,19,
dx =18000,6000,
dy =18000,6000,
i_parent_start = 1, 57,
j_parent_start = 1, 33,
parent_grid_ratio = 1, 3, 3,
我想问的是,那prep_chem_sources.inp中所列变量的设置是否正确。求解答,被这个疑问困扰了很长时间。
为何没有人理我呀,求大神解答疑惑,整过WRF-CHEM的同学都来看看呀
