Biogeochemistry of Carbon in the Amazonian Floodplains over a 2000-km Reach: Insights from a Process-Based Model
(American Meteorological Society, 2010)The influence of Amazonian floodplains on the hydrological, sedimentary, and biogeochemical river budget was investigated over a 2000-km reach. A process-based model relying on the closure of chemical fluxes and isotopic ... -
Winter Circulation Anomalies in the Western United States Associated with Antecedent and Decadal ENSO Variability
(American Meteorological Society, 2010)Previous research has shown that the impacts of ENSO variability on the winter climate of the western United States vary on decadal time scales. In this study, the relationship between fall season ENSO conditions and winter ... -
A Storm-Triggered Landslide Monitoring and Prediction System: Formulation and Case Study
(American Meteorological Society, 2010)Predicting the location and timing of mudslides with adequate lead time is a scientifically challenging problem that is critical for mitigating landslide impacts. Here, a new dynamic modeling system is described for ... -
Impacts of Climate Change and the End of Deforestation on Land Use in the Brazilian Legal Amazon
(American Meteorological Society, 2010)limate change scenarios vary considerably over the Amazon region, with an extreme scenario projecting a dangerous (from the human perspective) increase of 3.8°C in temperature and 30% reduction in precipitation by 2050. ... -
Estimating Actual Evapotranspiration from Satellite and Meteorological Data in Central Bolivia
(American Meteorological Society, 2010)patial estimates of actual evapotranspiration are useful for calculating the water balance of river basins, quantifying hydrological services provided by ecosystems, and assessing the hydrological impacts of land-use ... -
Ecosystem Feedbacks to Climate Change in California: Development, Testing, and Analysis Using a Coupled Regional Atmosphere and Land Surface Model (WRF3–CLM3.5)
(American Meteorological Society, 2010)regional atmosphere model [Weather Research and Forecasting model version 3 (WRF3)] and a land surface model [Community Land Model, version 3.5 (CLM3.5)] were coupled to study the interactions between the atmosphere and ... -
Variations in Subpixel Fire Properties with Season and Land Cover in Southern Africa
(American Meteorological Society, 2010)Some of the most widely used datasets for monitoring the world?s fires come from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensors aboard NASA?s Terra and Aqua satellites. For virtually all remote sensing ... -
The Amazon Frontier of Land-Use Change: Croplands and Consequences for Greenhouse Gas Emissions
(American Meteorological Society, 2010)The Brazilian Amazon is one of the most rapidly developing agricultural frontiers in the world. The authors assess changes in cropland area and the intensification of cropping in the Brazilian agricultural frontier state ... -
Physical Climate Response to a Reduction of Anthropogenic Climate Forcing
(American Meteorological Society, 2010)Recent research indicates that the warming of the climate system resulting from increased greenhouse gas (GHG) emissions over the next century will persist for many centuries after the cessation of these emissions, principally ... -
Satellite-Based Modeling of the Carbon Fluxes in Mature Black Spruce Forests in Alaska: A Synthesis of the Eddy Covariance Data and Satellite Remote Sensing Data
(American Meteorological Society, 2010)Scaling up of observed point data to estimate regional carbon fluxes is an important issue in the context of the global terrestrial carbon cycle. In this study, the authors proposed a new model to scale up the eddy covariance ... -
Biogeochemistry of the Amazonian Floodplains: Insights from Six End-Member Mixing Models
(American Meteorological Society, 2010)The influence of Amazonian floodplains on the hydrological, sedimentary, and biogeochemical river budget was investigated along the Vargem Grande??bidos reach, by applying six mixing models based on variable regional and/or ... -
Visualizing Spatial Heterogeneity of Western U.S. Climate Variability
(American Meteorological Society, 2010)Monthly climatologies (1971?2000 monthly averages) for stations in the western United States, obtained from the NOAA/National Climatic Data Center (NCDC), are used to illustrate the spatial variations in the annual cycle ... -
The Roles of Precipitation Increases and Rural Land-Use Changes in Streamflow Trends in the Upper Mississippi River Basin
(American Meteorological Society, 2010)Recent trends in precipitation and streamflow in the United States have become a particular focus of hydroclimatic research. The U.S. Hydro-Climatic Data Network (HCDN) has proven to be especially useful for the analysis ... -
Land Use and Reactive Nitrogen Discharge: Effects of Dietary Choices
(American Meteorological Society, 2010)Modern agriculture alters natural biological and geophysical processes, with magnitudes proportional to its spatial extent. Cultivation is also the main cause of artificially enhanced reactive nitrogen (Nr) availability ... -
Regional Differences in South American Monsoon Precipitation Inferred from the Growth and Isotopic Composition of Tropical Trees
(American Meteorological Society, 2010)The authors present results on the relationship between tree-ring proxies and regional precipitation for several sites in tropical South America. The responsiveness of oxygen isotopes (δ18O) and seasonal growth as precipitation ... -
Historical and Future Land-Cover Change in a Municipality of Ghana
(American Meteorological Society, 2010)Urban land-cover change is increasing dramatically in most developing nations. In Africa and in the New Juaben municipality of Ghana in particular, political stability and active socioeconomic progress has pushed the urban ... -
Storminess and Environmental Changes in the Mediterranean Central Area
(American Meteorological Society, 2010)Earth ecosystems are not static, and they respond to environmental changes, particularly climatic and anthropogenic. Precipitation varying in its extremeness, with shifts to greater or lesser intensity of individual storms ... -
The Influence of Tropical Deforestation on the Northern Hemisphere Climate by Atmospheric Teleconnections
(American Meteorological Society, 2010)Numerous studies have identified the regional-scale climate response to tropical deforestation through changes to water, energy, and momentum fluxes between the land surface and the atmosphere. There has been little research, ... -
