A Hydroclimatological Assessment of Regional Drought Vulnerability: A Case Study of Indiana Droughts
(American Meteorological Society, 2011)haracterizing and developing drought climatology continues to be a challenging problem. As decision makers seek guidance on water management strategies, there is a need for assessing the performance of drought indices. ... -
Design of Total Runoff Integrating Pathways (TRIP)—A Global River Channel Network
(American Meteorological Society, 1998)As a first step toward designing a comprehensive model for validating land surface hydrology and river flow in Earth system models, a global river channel network has been prepared at 1° latitude ? 1° longitude resolution. ... -
On the Surface-Convection Feedback during Drought Periods on the Canadian Prairies
(American Meteorological Society, 2011)inkages between the terrestrial ecosystem and precipitation play a critical role in regulating regional weather and climate. These linkages can manifest themselves as positive or negative feedback loops, which may either ... -
Watershed-Scale Response to Climate Change through the Twenty-First Century for Selected Basins across the United States
(American Meteorological Society, 2010)he hydrologic response of different climate-change emission scenarios for the twenty-first century were evaluated in 14 basins from different hydroclimatic regions across the United States using the Precipitation-Runoff ... -
Characterizing Climate-Change Impacts on the 1.5-yr Flood Flow in Selected Basins across the United States: A Probabilistic Approach
(American Meteorological Society, 2010)he U.S. Geological Survey Precipitation-Runoff Modeling System (PRMS) model was applied to basins in 14 different hydroclimatic regions to determine the sensitivity and variability of the freshwater resources of the United ... -
Hydrologic Effects of Urbanization and Climate Change on the Flint River Basin, Georgia
(American Meteorological Society, 2010)he potential effects of long-term urbanization and climate change on the freshwater resources of the Flint River basin were examined by using the Precipitation-Runoff Modeling System (PRMS). PRMS is a deterministic, ... -
Analyzing the Impacts of Frequency and Severity of Forest Fire on the Recovery of Disturbed Forest using Landsat Time Series and EO-1 Hyperion in the Southern Brazilian Amazon
(American Meteorological Society, 2010)stimation of fire impacts and forest recovery using remote sensing is difficult because of the heterogeneity of fire history (frequency, severity, and time since last fire) across burned forest landscapes. The authors ... -
Distribution of Landscape Types in the Global Historical Climatology Network
(American Meteorological Society, 2010)The Global Historical Climate Network version 2 (GHCNv.2) surface temperature dataset is widely used for reconstructions such as the global average surface temperature (GAST) anomaly. Because land use and land cover (LULC) ... -
Changes in Spring Snowpack for Selected Basins in the United States for Different Climate-Change Scenarios
(American Meteorological Society, 2010)pring snowpack is an important water resource in many river basins in the United States in areas where snowmelt comprises a large part of the annual runoff. Increasing temperatures will likely reduce snowpacks in the future, ... -
On the Hydrologic Adjustment of Climate-Model Projections: The Potential Pitfall of Potential Evapotranspiration
(American Meteorological Society, 2010)Hydrologic models often are applied to adjust projections of hydroclimatic change that come from climate models. Such adjustment includes climate-bias correction, spatial refinement (?downscaling?), and consideration of ... -
Satellite-Observed Surface Temperature Changes after the 2004 Taylor Complex Fire in Alaska
(American Meteorological Society, 2010)Land-use and land-cover change has been recognized as a key component in global climate change. In the boreal forest ecosystem, fires often cause significant changes in vegetation structure and surface biophysical ... -
Statistical Comparisons of Watershed-Scale Response to Climate Change in Selected Basins across the United States
(American Meteorological Society, 2010)n an earlier global climate-change study, air temperature and precipitation data for the entire twenty-first century simulated from five general circulation models were used as input to precalibrated watershed models for ... -
Exploring Cloud-to-Ground Lightning Earth Highpoint Attachment Geography by Peak Current
(American Meteorological Society, 2010)This study applied remotely sensed cloud-to-ground (CG) lightning strike location data, a digital elevation model (DEM), and a geographic information system (GIS) to characterize negative polarity peak current CG lightning ... -
Using Tree Rings to Predict the Response of Tree Growth to Climate Change in the Continental United States during the Twenty-First Century
(American Meteorological Society, 2010)In the early 1900s, tree-ring scientists began analyzing the relative widths of annual growth rings preserved in the cross sections of trees to infer past climate variations. Now, many ring-width index (RWI) chronologies, ... -
The Role of the North Atlantic Oscillation in Shaping Regional-Scale Peak Seasonal Precipitation across the Indian Subcontinent
(American Meteorological Society, 2010)The present study focuses on the impact of the North Atlantic Oscillation (NAO) in shaping the regional-level precipitation during the peak months of the two main rainy seasons over the Indian subcontinent. Monthly ... -
Land-Cover and Surface Water Change Drive Large Albedo Increases in South America
(American Meteorological Society, 2010)Albedo is an important factor affecting global climate, but uncertainty in the sources and magnitudes of albedo change has led to simplistic treatments of albedo in climate models. Here, the authors examine nine years ... -
MODIS Reflectance and Active Fire Data for Burn Mapping in Colombia
(American Meteorological Society, 2010)Satellite-based strategies for burned area mapping may rely on two types of remotely sensed data: postfire reflectance images and active fire detection. This study uses both methods in a synergistic way. In particular, ... -
