WRF simulation of flow over New Zealand


The WRF data for the period 06/20/2014 18:00 UTC to 06/23/2014 23:00 UTC is sampled at an altitude of 4 km on a 2088 x 1788 km (E-W x N-S) domain. The grid spacing is 6.0 km in both horizontal directions and thus 349 x 299 points are used. Sampling in time is at 1 hour intervals. Below is an image of the domain showing elevation contours for the New Zealand land masses.

The wrf data can be accessed via the link below. This is a direct-access, double-precision data file of the form u(Nx,Ny,5,Nt) where Nx=349, Ny=299, the 5 fields are p, theta, u, v, w and Nt=55. Note that the fields are ordered differently from the soda boundary forcing data file and that pressure is also included here.
