al. 2006 ), highlighted regions of strong coupling in global circulation models where antecedent soil moisture had significant influence on precipitation. This study analyzes land–atmosphere interactions over the South American continent, in particular over the La Plata River basin (LPB) using observations. The LPB (14°–38°S, 43°–67°W; Fig. 1a ) is widely recognized as a land–atmosphere coupling hotspot, where changes in land surface can alter the atmospheric state and modulate processes that

1. Introduction Land use change (LUC) modifies the biophysical characteristics of the land surface, by changing the surface albedo, the leaf area index (LAI), the stomatal resistance, and the surface roughness (e.g., Bonan 2008 ; Davin and de Noblet-Ducoudré 2010 ), thereby affecting regional climate conditions. Thus, LUC is thought to be a major driver of climate change on the regional scale ( de Noblet-Ducoudré et al. 2012 ; Jia et al. 2019 ). To investigate the impact of LUC on the

. Hence, there is a trade-off between explicitly resolving fine structure in the ASL, especially within the urban boundary layer, also in conjunction with flow dominated by complex terrain ( Fernando 2010 ). Furthermore, parameterizations of the ASL often employ the Monin–Obukhov similarity theory (MOST; Monin and Obukhov 1954 ), wherein horizontal homogeneity is assumed, meaning that individual buildings and land uses at subgrid scales are not explicitly resolved. This assumption can break down in

model simulations showing that additional moisture from urban sources contributes to increased downwind precipitation. Because the aerosol–precipitation feedbacks are still poorly understood and, thus, rarely included in regional climate models, we focus only on the effects of land use change on climate. Thus, the results of this study should be interpreted with care, keeping in mind that aerosol effects on surface energy balance and precipitation formation are not included in the models used here

Observational and modeling studies clearly demonstrate that land-use and land-cover change (LULCC) (e.g., Fig. 1 ) plays an important biogeophysical and biogeochemical role in the climate system from the landscape to regional and even continental scales ( Foley et al. 2005 ; Pielke et al. 2011 ; Brovkin et al. 2013 ; Luyssaert et al. 2014 ; Mahmood et al. 2014 ). The biogeochemical effect on the carbon budget is well recognized in both the scientific and policy-making communities. The

anthropogenic modification of spatial boundaries in land use/land cover through agricultural practices can have an influence on regional weather variability through these processes ( Brown and Arnold 1998 ). In addition, agricultural land use can influence the dynamics of the boundary layer through variations in surface roughness over the growing season, effectively modifying existing subsynoptic and mesoscale flow regimes by varying the intensity of turbulent mixing through the radix layer. The energy

water due to warming can readily create cascading effects on water resources ( Barrios et al. 2008 ; Ye and Grimm 2013 ). Since semiarid and arid regions are already water limited, any decrease in water supplies from droughts rapidly threatens both people and wildlife ( El-Khoury et al. 2015 ; Li et al. 2009 ). Furthermore, human activities in terms of land degradation, unsustainable land-use changes and water resource management, and inefficient irrigation methods significantly exacerbate the

1. Introduction Brazil has experienced unprecedented rates of land-use and land-cover change (LUCC) over the past several decades ( Nepstad et al. 2009 ), driven in part by the clearing of tropical rain forest and adjacent savanna for increasing agricultural production ( Morton et al. 2006 ). Indeed, Brazilian gross domestic agricultural product (GDAP, as measured by constant 2010 U.S. dollars) has risen steadily by nearly a factor of 5 since 1965, exceeding $104 billion (U.S. dollars) in 2015

1. Introduction The interaction between the land surface and atmosphere is an important element of the climate system. Land-use/land-cover changes (LULCCs) can modify the surface energy and water fluxes and can therefore affect climate at regional and broader scales. Within the land–atmosphere coupling “process chain” ( Santanello et al. 2011 ), the land surface affects precipitation by influencing planetary boundary layer (PBL) development thereby triggering and maintaining convection
