1. via local thermodynamic effects on the life-cycle of storms
VERA
VERA project will look at impacts of vegetation on rainfall in West Africa:
via local thermodynamic effects on the life-cycle of storms
regionally via recycling of moisture at the land surface
from the land’s impact on regional circulations

2. VERA UM runs UM8.2 Improved JULES land surface:
improved land cover map,
simplified soil information (all sandy soil)
April-July, 2 years, 2010 land cover
April-July, 2 years, 1950 land cover
40km P
12km P
12km E
4km E
2x July Great green wall
April-May Deforested Liberia
10x10 days to understand predictability
