RISTransition of the Large-Scale Atmospheric and Land Surface Conditions from the Dry to the Wet Season over Amazonia as Diagnosed by the ECMWF Re-Analysis
Publisher: American Meteorological Society
Abstract: Using 15-yr instantaneous European Centre for Medium-Range Weather Forecasts Re-Analysis (ERA) data, the authors have examined the large-scale atmospheric conditions and the local surface fluxes through the transition ...
Influence of Cold Air Intrusions on the Wet Season Onset over Amazonia
Publisher: American Meteorological Society
Abstract: Using 15-yr data from the European Centre for Medium-Range Weather Forecasts Re-Analysis (ERA-15), the authors found that rapid southeastward expansion of the rainy area from the western Amazon to southeastern Brazil is a ...
Intensification of Summer Rainfall Variability in the Southeastern United States during Recent Decades
Publisher: American Meteorological Society
Abstract: The variability of summer precipitation in the southeastern United States is examined in this study using 60-yr (1948?2007) rainfall data. The Southeast summer rainfalls exhibited higher interannual variability with more ...
Reply to “Comments on ‘Changes to the North Atlantic Subtropical High and Its Role in the Intensification of Summer Rainfall Variability in the Southeastern United States’”
Publisher: American Meteorological Society
Abstract: ecently Diem questioned the western ridge movement of the North Atlantic subtropical high (NASH) reported in a 2011 paper of Li et al. This reply shows more analysis that further strengthens the conclusions originally put ...
Changes to the North Atlantic Subtropical High and Its Role in the Intensification of Summer Rainfall Variability in the Southeastern United States
Publisher: American Meteorological Society
Abstract: his study investigates the changes of the North Atlantic subtropical high (NASH) and its impact on summer precipitation over the southeastern (SE) United States using the 850-hPa geopotential height field in the National ...
Unforced Surface Air Temperature Variability and Its Contrasting Relationship with the Anomalous TOA Energy Flux at Local and Global Spatial Scales
Publisher: American Meteorological Society
Abstract: nforced global mean surface air temperature is stable in the long term primarily because warm anomalies are associated with enhanced outgoing longwave radiation to space and thus a negative net radiative energy flux (, ...
Response of Subtropical Stationary Waves and Hydrological Extremes to Climate Warming in Boreal Summer
Publisher: American Meteorological Society
Abstract: AbstractSubtropical stationary waves may act as an important bridge connecting regional hydrological extremes with global warming. Observations show that the boreal summer stationary-wave amplitude (SWA) had a significantly ...
Comparison of Precipitation Datasets over the Tropical South American and African Continents
Publisher: American Meteorological Society
Abstract: Six rainfall datasets are compared over the Amazon basin, Northeast Brazil, and the Congo basin. These datasets include three gauge-only precipitation products from the Climate Prediction Center (CPC), Global Precipitation ...
Mass Footprints of the North Pacific Atmospheric Blocking Highs
Publisher: American Meteorological Society
Abstract: he mass footprints associated with atmospheric blocks over the North Pacific are evaluated by constructing daily tendencies of total mass over the blocking domain from three-dimensional mass fluxes throughout the life cycle ...
Moisture Source Changes Contributed to Different Precipitation Changes over the Northern and Southern Tibetan Plateau
Publisher: American Meteorological Society
Abstract: Precipitation on the Tibetan Plateau (TP) showed different spatial changes during 1979?2016, with an increasing trend over the northern Tibetan Plateau (NTP) and a slightly negative trend over the southern Tibetan Plateau ...
