lightning option=3 (LPI)

Postby lanlandeercy » Mon Aug 20, 2018 7:45 pm

Hi,
I am using WRFv4.00 to forecast lightning. I noticed WRF stops at the very beginning when I use lightning_option=3, which did not happen to lightning_option=1,2.
I wonder whether it’s due to the newer version of WRF or there’s something wrong with the scheme 3.
Can someone help please?
Thanks much!

My namelist.input is attached.
