* Treats each (file, time_index) pair as a frame. * Recomputes lat/lon, grid spacing, extent, and cities per frame. * Uses only netCDF4 + wrf-python for field access (no xarray).
* Same WRF variables (slp, U10, V10, ua, va, PBLH, height_agl). * Same PBLH-capped gust parameterization (cap at 1000 m, random offset). * Same Gaussian smoothing (sigma=1) for gusts. * Same ...
