When I use WRFDA 4.0.2,I found the forecsast result is not normal.There is lots of small precipitation.However,When I use fg directly to forecast,the result is normal.And I use WRF3.9.1.1 and WRFDA 3.9.1 with the same configure,the result is normal too.So is there a problem in WRFDA 4.0.2? Could anyone can tell me whether or not you have the problem too?
