Impact of Amazonian deforestation on precipitation reverses between seasons.

ABSTRACT: Tropical deforestation was found to cause large reductions in precipitation using a range of observation-based datasets¹. However, the limitations of satellite-based space-for-time statistical analysis have hindered understanding of the roles of reshaped mesoscale atmospheric circulation and regional precipitation recycling at different scales. These effects are considered nonlocal effects, which are distinct from the local effects governed by deforestation-induced reductions in evapotranspiration (ET). Here we show reversed precipitation responses to Amazon deforestation across wet and dry seasons. During the wet season, deforested grids experienced a noteworthy increase in precipitation (0.96 mm month^-1 per percentage point forest loss), primarily attributed to enha
