Dear WRFHELP,

I have just installed the wrf 4.1. real.exe is producing the following error.
------------------------------------------------------------------------------------------------
----- ERROR: The reference pressure is not monotonically decreasing
This tends to be caused by very high topography
(i,j) = 41 50 , topography = 6749.04199 m
k = 12 , reference pressure = 38790.1445 Pa
k = 13 , reference pressure = 38804.8125 Pa
