Hi NCAR,
In the modelling, we can create various domains with different grid resolutions. For example, d01 = 18km, d02 = 6km, and d03 = 2km if we d01 is the parent grid of d02 with parent ratio = 3, and if d02 is the parent grid of d03 with parent ratio = 3 as well.
If WRF is a mesoscale model, how fine is the accuracy of the model? Will it improve just by making finer grids until the domain’s scale becomes in several meters?
I’m so sorry if this question looks stupid but I’m quite new to this model. I wanted to use WRF, with ERA5 as the input boundary conditions, to predict pressure field, wind speed and wind direction. However, from my post processing results of WRFOUT data, it seems the mesoscale can’t accurately get the pressure drop near the a typhoon center and hence the discrepancy in the wind prediction as well. Furthermore, is mesoscale model enough to predict wind speed at a local scale (several meters: ~10m)
