ENSO Drives interannual variation of forest woody growth across the tropics
(Royal Soc, 2018-11-19)
Meteorological extreme events such as El Nino events are expected to affect tropical forest net primary production (NPP) and woody growth, but there has been no large-scale empirical validation of this expectation. We ...
Characterizing monthly temperature variability states and associated meteorology across southern South America
(Wiley-Blackwell, 2019-07-29)
Key spatiotemporal patterns of monthly scale temperature variability are characterized over southern South America using k-means clustering. The resulting clusters reveal patterns of temperature variability, referred to ...
A climatology of daily synoptic circulation patterns and associated surface meteorology over southern South America
(2019-01-01)
Synoptic circulation patterns, defined as anomalies in sea level pressure (SLP), 500 hPa geopotential height (Z500), and 250 hPa wind speed (V250) and referred to as large-scale meteorological patterns (LSMPs), are ...
The Impacts of Inter-El Nino Variability on the Tropical Atlantic and Northeast Brazil Climate
(AMER METEOROLOGICAL SOC, 2011)
In this study, observations and numerical simulations are used to investigate how different El Nino events affect the development of SST anomalies in the Atlantic and how this relates to the Brazilian northeast (NE) ...
Chaco low-level jet events characterization during the austral summer season
(Wiley Blackwell Publishing, Inc, 2002-12-27)
Previous studies showed a relationship between convection maxima and the convergence of vapor flux over southeastern South America. Nicolini and Saulo [2000] explored the hypothesis of an intensification of this mutual ...
A Comparison of GLDAS Soil Moisture Anomalies against Standardized Precipitation Index and Multisatellite Estimations over South America
(American Meteorological Society, 2015-02)
This study aims to compare simulated soil moisture anomalies derived from different versions of the Global Land Data Assimilation System (GLDAS), the standardized precipitation index (SPI), and a new multisatellite surface ...
Observational evidences on the modulation of the South American Low Level Jet east of the Andes according the ENSO variability
(COPERNICUS PUBLICATIONS, 2009)
The differences on the phase and wavelength of the quasi-stationary waves over the South America generated by El Nino (EN) and La Nina (LN) events seem to affect the daily evolution of the South American Low Level Jet east ...
North Tropical Atlantic influence on western Amazon fire season variability
(Blackwell Publishing Ltd, 2011-06)
The prevailing wet climate in the western Amazon is not favorable to the natural occurrence of fires. Nevertheless, the current process of clearing of humid forests for agriculture and cattle ranching has increased the ...
