Long-term sustainability of the water-agriculture-energy nexus in Brazil’s MATOPIBA region: A case study using system dynamics.
The global demand for agricultural commodities has driven extensive land conversion to agriculture in Brazil, especially in the MATOPIBA region. This area encompasses the Rio Grande Basin, a major tributary of the Sao Francisco Basin that is known for expanding intensive irrigated agriculture and hy...

Long-term variability, extremes and changes in temperature and hydrometeorology in the Amazon region: A review.
This review discusses observed hydroclimatic trends and future climate projections for the Amazon. Warming over this region is a fact, but the magnitude of the warming trend varies depending on the datasets and length of the analyzed period. The warming trend has been more evident since 1980 and has...

Synoptic patterns of extreme precipitation events in northeast Brazil.
Northeast Brazil (NEB) is one of the driest regions in the country, with some areas, such as the sertão, receiving less than 400 mm/year. Despite this aridity, NEB is infuenced by various synoptic-scale systems that contribute to intense rainfall events throughout the year. This study aimed to iden...

Reducing uncertainties of climate projections on solar energy resources in Brazil.
The share of solar power in Brazils electrical grid has rapidly increased, relieving GHG emissions and diversifying energy sources for greater energy security. Besides that, solar resource is susceptible to climate change, adding uncertainty to electrical grid resilience. This study uses satellite a...

Spatio-temporal tendencies of urban land surface temperature on the Andean piedmont under climate change: A case study of Metropolitan Lima, Peru (1986–2024).
The increase in land surface temperature (LST) in megacities has contributed to global warming due to poor urban planning and high population concentration. This study analyzes spatio-temporal trend patterns of LST in the city of Metropolitan Lima, Peru, during the summers of 19862024. The Mann-Kend...

Isoprene nitrates drive new particle formation in Amazon’s upper troposphere.
New particle formation (NPF) in the tropical upper troposphere is a globally important source of atmospheric aerosols1, 2, 3-4. It is known to occur over the Amazon basin, but the nucleation mechanism and chemical precursors have yet to be identified2. Here we present comprehensive in situ aircraft ...

South Atlantic convergence zone and ENSO occurrence in the 2000–2021 period.
In this study we defined the association of SACZ episodes with ENOS phases during the 2000–2021 summer seasons, considering November to March months, and the circulation associated patterns. Each SACZ episode was classified when OLR values were below 220 W m− 2 and precipitable water values abov...
