Hello Everyone,
I want to see how water vapor influences the precipitation. For this, I scaled the QVAPOR by a factor of 0.8 below the 800 hPa layer in the WRFRST file of the control simulation for 8 hours of lead time of the precipitation event and then restarted the simulation. However, while checking the restarted model output (modified QVAPOR case), it shows extremely low values of QVAPOR profile (even negative for some layers), and no precipitation occurs. So, my question is, is it physically reasonable to modify QVAPOR directly in the WRFRST file? Could such modifications violate mass conservation? If direct modification is not advisable, what would be a better approach to assess the impact of water vapor on precipitation?
Any suggestions, insights, or recommendations would be greatly appreciated.
Thank you in advance.
