Interannual Variability of Sea Surface Height over the Black Sea: Relation to Climatic Patterns
(American Meteorological Society, 2008)Sea surface height (SSH) variability is presented over the Black Sea during 1993?2005. The 1/4° ? 1/4° resolution daily SSH fields are formed using optimal interpolation of available altimeter data. SSH variability reveals ... -
Regional Projections of Future Seasonal and Annual Changes in Rainfall and Temperature over Australia Based on Skill-Selected AR4 Models
(American Meteorological Society, 2008)Daily data from climate models submitted to the Fourth Assessment of the Intergovernmental Panel on Climate Change are compared with daily data from observations over Australia by measuring the overlap of the probability ... -
Identifying Climatic Controls on Ring Width: The Timing of Correlations between Tree Rings and NDVI
(American Meteorological Society, 2008)The authors examine the effects of latitude and life history on the timing of relationships between satellite measures of normalized difference vegetation index (NDVI) and ground-based measures of tree-ring width in forests ... -
Characterizing Variability of the Urban Physical Environment for a Suite of Cities in Rondônia, Brazil
(American Meteorological Society, 2008)Urban environments are characterized by high spectral and spatial heterogeneity and, as a consequence, most urban pixels in moderate-resolution imagery contain multiple land-cover materials. Despite these complexities, ... -
The Western Arctic Linkage Experiment (WALE): Overview and Synthesis
(American Meteorological Society, 2008)The primary goal of the Western Arctic Linkage Experiment (WALE) was to better understand uncertainties of simulated hydrologic and ecosystem dynamics of the western Arctic in the context of 1) uncertainties in the data ... -
Visualizing the Large-Scale Patterns of ENSO-Related Climate Anomalies in North America
(American Meteorological Society, 2009)The variations of large-scale climatic controls and surface responses through the annual cycle during strong positive (El Niño) and negative (La Niña) phase ENSO events are analyzed to assess the within-year and among-year ... -
Estimating Seasonal Changes in Volumetric Soil Water Content at Landscape Scales in a Savanna Ecosystem Using Two-Dimensional Resistivity Profiling
(American Meteorological Society, 2008)Water distributed in deep soil reservoirs is an important factor determining the ecosystem structure of water-limited environments, such as the seasonal tropical savannas of South America. In this study a two-dimensional ... -
The Role of Irrigation Expansion in Past and Future Temperature Trends
(American Meteorological Society, 2008)Expansion of irrigated land can cause local cooling of daytime temperatures by up to several degrees Celsius. Here the authors compare the expected cooling associated with rates of irrigation expansion in developing countries ... -
The Power of Monitoring Stations and a CO2 Fertilization Effect: Evidence from Causal Relationships between NDVI and Carbon Dioxide
(American Meteorological Society, 2008)Two hypotheses are tested: 1) monitoring stations (e.g., Mauna Loa) are not able to measure changes in atmospheric concentrations of CO2 that are generated by changes in terrestrial vegetation at distant locations; 2) ... -
Landslide Risk Analysis using a New Constitutive Relationship for Granular Flow
(American Meteorological Society, 2008)In this study, landslide potential is investigated, using a new constitutive relationship for granular flow in a numerical model. Unique to this study is an original relationship between soil moisture and the inertial ... -
Landslide Erosion Rate in the Eastern Cordillera of Northern Bolivia
(American Meteorological Society, 2007)The northeastern edge of the Bolivian Eastern Cordillera is an example of a tectonically active plateau margin where orographically enhanced precipitation facilitates very high rates of erosion. The topography of the ... -
Human Influences on Wildfire in Alaska from 1988 through 2005: An Analysis of the Spatial Patterns of Human Impacts
(American Meteorological Society, 2008)Boreal ecosystems in Alaska are responding to climate change in many ways, including changes in the fire regime. While large-scale wildfires are an essential part of the boreal forest ecosystem, humans are changing fire ... -
Comparison of a Land Surface Model (SSiB) to Three Parameterizations of Evapotranspiration—A Study Based on ISLSCP Initiative I Data
(American Meteorological Society, 1998)Four different methods of estimating land surface evapotranspiration are compared by forcing each scheme with near-surface atmospheric and soil- and vegetation-type forcing data available through International Satellite ... -
Analysis of Cerrado Physiognomies and Conversion in the MODIS Seasonal–Temporal Domain
(American Meteorological Society, 2005)The ?cerrado? biome in central Brazil is rapidly being converted into pasture and agricultural crops with important consequences for local and regional climate change and regional carbon fluxes between the atmosphere and ... -
Water Flux in a Cashew Orchard during a Wet-to-Dry Transition Period: Analysis of Sap Flow and Eddy Correlation Measurements
(American Meteorological Society, 2004)Information regarding biosphere?atmosphere interactions is important in the study of a hydrological cycle. To this purpose, xylem sap flow (SF) using the Granier system and evapotranspiration (ET) using the eddy correlation ... -
Variability in Springtime Thaw in the Terrestrial High Latitudes: Monitoring a Major Control on the Biospheric Assimilation of Atmospheric CO2 with Spaceborne Microwave Remote Sensing
(American Meteorological Society, 2004)Evidence is presented from the satellite microwave remote sensing record that the timing of seasonal thawing and subsequent initiation of the growing season in early spring has advanced by approximately 8 days from 1988 ... -
Twentieth-Century Sea Surface Temperature Patterns in the Pacific during Decadal Moisture Regimes over the United States
(American Meteorological Society, 2004)Three great moisture anomalies were observed during the twentieth century over the western United States: a pluvial from 1905 to 1917, the Dust Bowl drought (1929?40), and the Southwestern drought of 1946?56. A composite ... -
