The soil moisture problem

[Tom]

Hi all!
I am using WRF4.2 to simulate a pricipitation process.But the soil moisture is strange.The dark purple area has little change in all simulation period(dedatil in the attachement).However those areas have precipitation variations.
The forcing data and SST data i used is NCEP.
What should i do to sovle this problem.

The plots you posted are soil moisture, I guess. How about precip?

Many apologies for the long delay in response.The corresponding precipitation is at attachment.The result i showed is just a part of the result. But the dark purple area has little change in all simulation period
Modify the forcing data:The forcing data i used is ERA5.
Thank your reply!
