unbelievable snow cover !

Post by alfe » Sun Mar 03, 2013 11:42 am

Hello,
I think something is not going well... I did not try to look at this parameter before, and I wish not to have seen it.... Because this is quite mad. The snow cover %, is increasing for the next 48h on my domain although there is no precipitation at all. Moreover, temperature are positive and no snow melt in the forecast. On the opposite, the snow cover is increasing. Actually, this is happening whatever the Dx value is : 3km, 9km or 25km. I run multiple simulation configurations with ARW core and they are all wrong considering the snow cover. Not only at the initialization, but also for the forecast.
I have the last beta version of EMS system, and I use NOAH LSM with PBL = 1, ARW core. I have the MODIS data land use.
Obviously something is completely wrong here! So if anybody has an idea that would be appreciated.
Thanks,
