Hailstorm events in the Central Andes of Peru: Insights from historical data and radar microphysics
(European Geosciences Union, 2024)
Hailstorms, while fascinating from a meteorological perspective, pose significant risks to communities, agriculture, and infrastructure. In regions such as the Central Andes of Peru, the characteristics and frequency of ...
The new record of drought and warmth in the Amazon in 2023 related to regional and global climatic features
(Springer, 2024)
In 2023 Amazonia experienced both historical drought and warm conditions. On October 26th 2023 the water levels at the port of Manaus reached its lowest record since 1902 (12.70 m). In this region, October monthly maximum ...
Hydrological Response Assessment of Land Cover Change in a Peruvian Amazonian Basin Impacted by Deforestation Using the SWAT Model
(MDPI, 2024)
The watershed hydrologic conditions in the Madre de Dios (MDD) Basin in the Peruvian Amazon have been irreversibly impacted by deforestation and changes in land cover. These changes have also had detrimental effects on the ...

Advancing South American Water and Climate Science through Multidecadal Convection-Permitting Modeling
(American Meteorological Society, 2024-01-08)
South America’s hydroclimate sustains vibrant communities and natural ecosystems of extraordinary biodiversity including the Andes Cordillera, and the Orinoco, La Plata, and Amazon basins. Global warming and land-use change ...
The 2022-23 drought in the South American Altiplano: ENSO effects on moisture flux in the western Amazon during the pre-wet season
(Servicio Nacional de Meteorología e Hidrología del Perú, 2024)
The 2022-23 hydrological year in the Lake Titicaca, Desaguadero River, and Lake Poopó hydrological system (TDPS) over the South American Altiplano constituted a historically dry period. This drought was particularly severe ...
Benefits of the coupling in the downscaling the South American climate
(Elsevier, 2024)
We evaluate the benefits of the use of a regional coupled model over its stand-alone atmospheric component when forced by reanalysis data in the simulation of the South American climate. We find that the coupling allows ...

Synoptic and cloud-scale aspects related to an extreme rainfall event that occurred in April 2019 in the city of Rio de Janeiro (Brazil)
(Servicio Nacional de Meteorología e Hidrología del Perú, 2024)
The development, rate, and duration of extreme rainfall events over a region depend on the coexistence and strength of multiple atmospheric physical conditions. Then, understanding the synoptic and cloud-scale aspects is ...
