Groundwater isotope ratios reflect convective and stratiform (paleo)precipitation fractions in Brazil
(2020-06-01)
The stable isotope ratios of oxygen and hydrogen in shallow groundwater reflect the long-term amount-weighted mean isotopic composition of precipitation. Here, we report the isotopic composition of more than 1000 shallow ...
Statistics on tropical convective storms observed by radar
(1996-10-01)
Convective storm rainfall is of special importance to urban hydrological studies due to its temporal and spatial variability. Although dense networks of recording rain gauges can be employed to characterize such rainfall, ...

Synoptic forcing associated with extreme precipitation events over Southeastern South America as depicted by a CORDEX FPS set of convection-permitting RCMs
(Springer, 2021-01)
Southeastern South America (SESA) stands out as a remarkable region of occurrence of deep convection. This is mainly due to the proximity of the Andes, which eventually determine their magnitude and intensity. In this work, ...
Can stable isotopes ride out the storms? The role of convection for water isotope in models, records, and paleoaltimetry studies in the central Andes
(Elsevier, 2014-10-24)
Abstract: Globally, changes in stable isotope ratios of oxygen and hydrogen (δ18Oand δD) in the meteoric water cycle result from distillation and evaporation processes. Isotope fractionation occurs when air masses rise in ...
Parametrizações convectivas no modelo WRF e sua relação com a precipitação durante ciclogêneses no sudeste da América do Sul
(Universidade Federal de Santa MariaBRMeteorologiaUFSMPrograma de Pós-Graduação em Meteorologia, 2014-02-25)
The Weather Research and Forecasting (WRF) model is used in the simulation of
26 cases of cyclogenesis in southeastern South America, on the cyclogenetic region near
the La Plata River mouth. The simulations comprised ...
Recent changes in the precipitation-driving processes over the southern tropical Andes/western Amazon
(Springer, 2020)
Analyzing December-February (DJF) precipitation in the southern tropical Andes-STA (12 circle S}; > 3000 m.a.s.l) allows revisiting regional atmospheric circulation features accounting for its interannual variability over ...
