WRF sea level pressure strange

[WENSHUO HUANG]

Dear WRF experts,
I am trying to plot slp using wrf-python slp diagnostic. The slp shows the strange pattern, which has a lot extreme and unnormal high values at the beginning of simualtion. I am confused about the results. Here is my namelist. Does anyone know what causes the strange slp?
Thank you so much！

Can you upload your wrfout file for me to take a look?

If this case is done successfully, I am suspicious that the weird SLP is caused by errors in your python script.

Thank you for your advice! I reviewed my python code, the error is caused by the script itself!
