Detailed local weather modelling may be needed to represent the effects of mountains or land / sea temperature differences on the wind; to get the effects of land roughness on the surface wind speed (e.g. during tropical cyclones); to get the extreme minimum or maximum ground temperature (for gas pipeline projects); to give information on the humidity and temperature (for working conditions).
3D animation of hurricane Katrina computed with WRF.
The ground overlay shows the temperature and the streamlines present the wind flow in the hurricane. During the top view the cloud cover is also shown.
