Circumpolar Arctic Tundra Vegetation Change Is Linked to Sea Ice Decline
(American Meteorological Society, 2010)Linkages between diminishing Arctic sea ice and changes in Arctic terrestrial ecosystems have not been previously demonstrated. Here, the authors use a newly available Arctic Normalized Difference Vegetation Index (NDVI) ... -
Intraseasonal Variability of Satellite-Derived Rainfall and Vegetation over Southern Africa
(American Meteorological Society, 2010)Satellite-derived rainfall and vegetation [normalized difference vegetation index (NDVI)] data for the period 1981?2000 are used to reveal spatial and temporal interrelationships via principal component analysis. The ... -
Characterizing the Spatial Patterns of Global Fertilizer Application and Manure Production
(American Meteorological Society, 2010)Agriculture has had a tremendous impact on soil nutrients around the world. In some regions, soil nutrients are depleted because of low initial soil fertility or excessive nutrient removals through intense land use relative ... -
Nonfrontier Deforestation in the Eastern Amazon
(American Meteorological Society, 2010)While interest in Amazonian deforestation mostly focuses on frontier areas, the amount of forest cover in areas already dominated by human settlement is also changing. Secondary forests play an increasingly important role ... -
Biophysical Evaluation of Land-Cover Products for Land–Climate Modeling
(American Meteorological Society, 2009)The need for accurate characterization of the land surface as boundary conditions in climate models has been recognized widely in the climate modeling community. A large number of land-cover datasets are currently used in ... -
Measuring Woody Encroachment along a Forest–Savanna Boundary in Central Africa
(American Meteorological Society, 2009)Changes in net area of tropical forest are the sum of several processes: deforestation, regeneration of previously deforested areas, and the changing spatial location of the forest?savanna boundary. The authors conducted ... -
Twentieth-Century Droughts and Their Impacts on Terrestrial Carbon Cycling in China
(American Meteorological Society, 2009)Midlatitude regions experienced frequent droughts during the twentieth century, but their impacts on terrestrial carbon balance are unclear. This paper presents a century-scale study of drought effects on the carbon balance ... -
Challenges to Reproduce Vegetation Structure and Dynamics in Amazonia Using a Coupled Climate–Biosphere Model
(American Meteorological Society, 2009)The Amazon rain forest constitutes one of the major global stocks of carbon. Recent studies, including the last Intergovernmental Panel on Climate Change report and the Coupled Climate Carbon Cycle Model Intercomparison ... -
Vegetation Control in the Long-Term Self-Stabilization of the Liangzhou Oasis of the Upper Shiyang River Watershed of West-Central Gansu, Northwest China
(American Meteorological Society, 2009)This paper explores the relationship between vegetation in the Liangzhou Oasis in the Upper Shiyang River watershed (USRW) of west-central Gansu, China, and within-watershed precipitation, soil water storage, and oasis ... -
Recent Declines in Western U.S. Snowpack in the Context of Twentieth-Century Climate Variability
(American Meteorological Society, 2009)A monthly snow accumulation and melt model was used with monthly Precipitation-elevation Regressions on Independent Slopes Model (PRISM) temperature and precipitation data to generate time series of 1 April snow water ... -
Energy Balance Partitioning and Net Radiation Controls on Soil Moisture–Precipitation Feedbacks
(American Meteorological Society, 2009)A series of model runs using the University of Oklahoma?s Advanced Regional Prediction System (ARPS) were conducted to investigate the relative impacts of energy balance partitioning and net radiation on soil moisture?pr ... -
The Influence of El Niño on the Spring Fallout of Asian Bird Species at Attu Island
(American Meteorological Society, 2009)Several studies have documented the effect of the recent secular climate warming on the distributions and geographical ranges of birds. Here the authors report the strong impact of a recurring climatic pattern in the ... -
Enhanced Classifications of Engineered Paved Surfaces for Urban Systems Modeling
(American Meteorological Society, 2009)There is a greater need than ever for the ability to accurately model urban system impacts resulting around the planet. Rapid urbanization is transforming landscapes from vegetation to an engineered infrastructure and thus ... -
Consistency in Global Climate Change Model Predictions of Regional Precipitation Trends
(American Meteorological Society, 2009)Projections of human-induced climate change impacts arising from the emission of atmospheric chemical constituents such as carbon dioxide typically utilize multiple integrations (or ensembles) of numerous numerical climate ... -
Effects of Recent Environmental Changes on Global Seismicity and Volcanism
(American Meteorological Society, 2009)A covariation of recent global environmental changes and seismicity on Earth is demonstrated. Presently, rising concern about anthropogenic activities and their consequences on the cryosphere and environment have always ... -
Concurrent Cloud-to-Ground Lightning and Precipitation Enhancement in the Atlanta, Georgia (United States), Urban Region
(American Meteorological Society, 2008)This study explores how the Atlanta, Georgia (United States), urban region influences warm-season (May through September) cloud-to-ground lightning flashes and precipitation. Eight years (1995?2003) of flashes from the ... -
Identification of Nonlinear Behavior in Transient Climate Change Projections of Soil Moisture over the United States
(American Meteorological Society, 2009)While most projections of climate change and its regional impacts focus on overall changes in the state of the climate system, useful information can also be found in the evolution of the climate system from one state to ... -
Estimating the Surface Area of Small Rivers in the Southwestern Amazon and Their Role in CO2 Outgassing
(American Meteorological Society, 2008)A recent estimate of CO2 outgassing from Amazonian wetlands suggests that an order of magnitude more CO2 leaves rivers through gas exchange with the atmosphere than is exported to the ocean as organic plus inorganic carbon. ... -
Diurnal to Annual Precipitation Sensitivity to Convective and Land Surface Schemes
(American Meteorological Society, 2008)Precipitation?s diurnal to annual variance distribution and atmospheric water cycle component interactions are examined globally for sensitivity to convective and land surface schemes. The main regional features of statistics ... -
Terrestrial Vegetation Dynamics and Global Climate Controls in North America: 2001–05
