Planetary Boundary Layer (PBL) Question

[teoxu]

Hi all,

 

I have run 3 models using SimSphere. The first one varies soil moisture (10% - 100%) with no vegetation cover. The second varies fractional vegetation cover (0% - 100%) for deciduous forests at 2m. The third one varies fractional vegetation cover (0% - 100%) for deciduous forests at 20m. The relationships are as follows:

 

1. Soil moisture with no vegetation cover:

 

INCREASED soil moisture

INCREASED latent heat

DECREASED sensible heat

DECREASED PBL depth

 

2. Deciduous forest at height 2m:

 

INCREASED fractional vegetation cover

DECREASED latent heat

INCREASED sensible heat

INCREASED PBL depth

 

3. Deciduous forest at height 20m:

 

INCREASED fractional vegetation cover

DECREASED latent heat

DECREASED sensible heat

DECREASED PBL depth

 

I have attached the excel files of the results generated from the model runs along with this thread.

 

Could someone please help in explaining the relationships in these 3 scenarios please?

 

Thank you so much!
