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 ...
Backward adaptive brightness temperature threshold technique (BAB3T): A methodology to determine extreme convective initiation regions using satellite infrared imagery
(Molecular Diversity Preservation International, 2020-01)
Thunderstorms in southeastern South America (SESA) stand out in satellite observations as being among the strongest on Earth in terms of satellite-based convective proxies, such as lightning flash rate per storm, the ...
Orographic rainfall hot spots in the Andes‐Amazon transition according to the TRMM precipitation radar and in situ data
(American Geophysical Union (AGU), 2017-06-16)
The Andes‐Amazon transition, along the eastern Peruvian Andes, features “hot spots” with strong precipitation. Using 15 years of Tropical Rainfall Measuring Mission PR data we established a robust relation between terrain ...
Contrasting climates at both sides of the Andes in Argentina and Chile
(Frontiers Media S.A., 2019-05)
The prominent Andes cordillera induces significant differences in climates between its eastern and western slopes. These climatic differences are largely reflected by contrasting vegetation and ice coverages but remain ...
High-elevation monsoon precipitation processes in the central Andes of Peru
(American Geophysical Union, 2020-12-27)
Measurements at the high-elevation Lamar Observatory in the Mantaro Valley (MV) in the Central Andes of Peru demonstrate a diurnal cycle of precipitation characterized by convective rainfall during the afternoon and nighttime ...
Radar-Observed Characteristics of Precipitation in the Tropical High Andes of Southern Peru and Bolivia
(American Meteorological Society, 2018-07-06)
This study used the first detailed radar measurements of the vertical structure of precipitation obtained in the central Andes of southern Peru and Bolivia to investigate the diurnal cycle and vertical structure of ...
Classificação de sistemas meteorológicos e comparação da precipitação estimada pelo radar e medida pela rede telemétrica na bacia hidrográfica do alto Tietê
(Sociedade Brasileira de Meteorologia, 2009)
Foram analisadas características da precipitação estimada a partir de 145.194 campos de refletividade, de um total de 827 dias entre 1998 e 2003, obtidos do Radar Meteorológico de São Paulo (RSP). Os eventos foram classificados ...
Precipitation characteristics at two locations in the tropical andes by means of vertically pointing micro-rain radar observations
(2019)
© 2019 by the authors. In remote areas with steep topography, such as the Tropical Andes, reliable precipitation data with a high temporal resolution are scarce. Therefore, studies focusing on the diurnal properties of ...
