wrf-python getvar works differently in Windows and Linux environment

[Yu Hiraga]

Hello all,

I found the issue in the title.

I was using "getvar" function to compute precipitable water and cape_2d from the wrfout file.

When I ran "getvar" in our Linux machine, it produced odd (i.e., too high, low, and discontinuous in spacial distribution) values of the precipitable water and cape.

I investigated the issue, and when I transferred the SAME wrfout file to my Windows environment and ran "getvar", it resulted in different values of the precipitable water and cape, which are in the acceptable range.

I confirmed that both of-python installed in Linux and Windows are the same version (1.3.4.1).

Additionally, I noticed that, when I ran "getvar" using meta=True/False in our Linux, environment, it resulted in different values, though not the same as the one in Windows.

Thus, I thought the "meta" option may be related to this issue, but i couldn't find the solution.

Anyone has any thoughts on this?

I really appreciate your cooperation.

Best,

Hello Yusuke,

I myself have found a similar issue when plotting SLP or CAPE variables with wrf-python. 

At first I thought it was a version issue, but after checking with different colleagues I realized it has to be related to the machine environment.

Did you discover anything new?

Thanks a lot,

Jana.
