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
