The WRF Domain Tool, together with a shapefile, allows us to plot the WRF domain.
Here’s an example program that plots the nest domain.
import wrf_domain_tool.domain_generator as WRF
wrf = WRF.WRFDomain([
'https://geo.datav.aliyun.com/areas_v3/bound/100000.json', # 中国
'https://geo.datav.aliyun.com/areas_v3/bound/510000.json' # 四川
],dx_base=27000,
ratios=[1, 3])
wrf.load_shapefiles()
wrf.compute_domain_params()
wrf.write_namelist("namelist.wps")
wrf.plot_domains()
Here’s an example that multiple domains’ namelist.
