############################################################################# # # # ww3_tp2.13 Test script for WW-III, two-dimensional propagation. # # Propagation under angle with grid (tripole). # # # # Remarks : # # # # - This grid is based on a nominally 0.24 degree global tripole grid # # provided by Alan Walcraft (NRL). The "0.24 degree" here refers # # to the resolution at the equator. Here, only higher latitudes are # # included (so in fact, it has only two poles, both at the top). This # # resulting grid is described by files named *.1500x200 # # # # For grid *.1500x200 : # # # # The min. grid spacing along i is approx. 5.5 km (1/20 deg lat) # # The median grid spacing along i is approx. 10.4 km (1/11 deg lat) # # The max. grid spacing along i is approx. 12.2 km (1/9 deg lat) # # # # The min. grid spacing along j is approx. 10.5 km (1/11 deg lat) # # The median grid spacing along j is approx. 11.3 km (1/10 deg lat) # # The max. grid spacing along j is approx. 15.2 km (1/7 deg lat) # # # # One should also be aware that this grid has poor characteristics over # # some land areas (near the two northern poles). Therefore, it is not # # recommended to use it without the bathymetry. Contrast with the Arctic # # grid, for which we are able to run a case with no bathymetry (deep # # water). # # # # To make the computation time of the regtest more manageable, a mask is # # used to activate only a small portion of the overall grid points # # available in the *.1500x200 files. # # The active points are north of the Kara Sea, # # Severnaya Zemlya (Russia), and Franz Josef Land (Russia) # # # # For active portion of grid, defined by the mask : # # # # The min. grid spacing along i is approx. 10.5 km # # The median grid spacing along i is approx. 10.7 km # # The max. grid spacing along i is approx. 11.0 km # # # # The min. grid spacing along j is approx. 10.1 km # # The median grid spacing along j is approx. 10.4 km # # The max. grid spacing along j is approx. 10.7 km # # # # Note that the min grid spacing of sea points in *.1500x200 grid is # # quite a bit smaller than the points activated by the mask. Therefore, # # with different mask (or no mask), one will need to change the CFL # # time step. # # # # Some plots are provided with the regtest: # # * depth.png : depth on this tripole grid # # * i_index_active_points_zoom1.png : # # i-index on the subset grid, active points (via mask) are shown # # in black, shoreline is white, 300 m contour is yellow # # * i_index_active_points_zoom2.png : # # like i_index_active_points_zoom1.png , but different zoom level # # * j_index.png : j-index on the subset grid # # * distance_on_jj.png : distances (in km) looking along j-axis # # * distance_on_ii.png : distances (in km) looking along i-axis # # # # files in /input/ : # # 1) depth.1500x200, lat.1500x200, lon.1500x200 # # : no explanation needed # # 2) mask1.1500x200 : mask with seam treated as exception points # # # # Sample run_test commands : # # (Note: mpirun commands differ by local system) # # ./bin/run_test -n 3 -p mpirun -s PR3_MPI ../model ww3_tp2.13 # # # # Erick Rogers, Apr 4 2014 # # # ############################################################################# # # more notes: # # input_1099x1500 : # * only sea points north of 45N are not masked (this is called mask1) # * propagation only # # input_1099x1500B # * as with 1099x1500, propagation only # * experimenting with HYCOM inputs (currents, winds, water levels, ice) # * dates changed to match available HYCOM inputs # # input_1099x1500C # * as with 1099x1500 and input_1099x1500B, still propagation only # * now using full grid (this is called mask2) # # input_1099x1500D # * back to heavily-masked grid (mask1) # * now includes source terms. # # input_1099x1500E # * full grid (mask2) # * includes source terms. # # input_1099x1500F # * like E but includes C_sigma # ############################################################################# ################# END INFO FILE DESCRIPTION ################################# #############################################################################
