Stream Discharge in Tropical Headwater Catchments as a Result of Forest Clearing and Soil Degradation
(American Meteorological Society, 2012)ropical Africa is affected by intense land-use change, particularly forest conversion to agricultural land. In this study, the stream discharge of four small headwater catchments located within an area of 6 km2 in western ... -
The Global Drought Monitor Portal: The Foundation for a Global Drought Information System
(American Meteorological Society, 2012)he international scientific community has long recognized the need for coordinated drought monitoring and response, but many factors have prevented progress in the development of a Global Drought Early Warning System ... -
An Evaluation of Multiscalar Drought Indices in Nevada and Eastern California
(American Meteorological Society, 2012)evada and eastern California are home to some of the driest and warmest climates, most mountainous regions, and fastest growing metropolitan areas of the United States. Throughout Nevada and eastern California, snow-dominated ... -
Impacts of Land–Atmosphere Feedbacks on Deep, Moist Convection on the Canadian Prairies
(American Meteorological Society, 2011)he purpose of this study was to focus on how anomalies in the normalized difference vegetation index (NDVI; a proxy for soil moisture) over the Canadian Prairies can condition the convective boundary layer (CBL) so as to ... -
Temperature, Precipitation, and Lightning Modification in the Vicinity of the Athabasca Oil Sands
(American Meteorological Society, 2011)he Athabasca oil sands development in northeast Alberta, Canada, has disturbed more than 500 km2 of boreal forest through surface mining and tailings ponds development. In this paper, the authors compare the time series ... -
Meteorological Impacts of Forest Mortality due to Insect Infestation in Colorado
(American Meteorological Society, 2012)hysical characteristics of forests and other ecosystems control land?atmosphere exchanges of water and energy and partly dictate local and regional meteorology. Insect infestation and resulting forest dieback can alter ... -
Biases and Model Agreement in Projections of Climate Extremes over the Tropical Pacific
(American Meteorological Society, 2011)sing the Coupled Model Intercomparison Project phase 3 (CMIP3) general circulation models (GCMs), projections of a range of climate extremes are explored for the western Pacific. These projections include the 1-in-20-yr ... -
A Simple, Minimal Parameter Model for Predicting the Influence of Changing Land Cover on the Land–Atmosphere System
(American Meteorological Society, 2011)he impacts of changing land cover on the soil?vegetation?atmosphere system are numerous. With the fraction of land used for farming and grazing expected to increase, extensive alterations to land cover such as replacing ... -
Time Scales of Terrestrial Carbon Response Related to Land-Use Application: Implications for Initializing an Earth System Model
(American Meteorological Society, 2011)he dynamic vegetation and carbon cycling component, LM3V, of the Geophysical Fluid Dynamics Laboratory (GFDL) prototype Earth system model (ESM2.1), has been designed to simulate the effects of land use on terrestrial ... -
Mesocirculation Associated with Summer Convection over the Central Antilles
(American Meteorological Society, 2011)he mesoscale structure of the circulation and convection over central Caribbean Antilles islands in midsummer is analyzed. Afternoon thunderstorms are frequent over islands such as Hispaniola and Jamaica as confluent trade ... -
Will Amazonia Dry Out? Magnitude and Causes of Change from IPCC Climate Model Projections
(American Meteorological Society, 2011)he Amazon rain forest may undergo significant change in response to future climate change. To determine the likelihood and causes of such changes, the authors analyzed the output of 24 models from the Intergovernmental ... -
Bootstrapping Wildfire Selectivity for the Forest Types of Canton Ticino (Switzerland)
(American Meteorological Society, 2011)isturbances spreading through the landscape, like wildfires, are essential processes in modeling landscape structure and dynamics. Like other disturbances, fire may spread from a local epicenter with a propagation rate ... -
Impacts of Climate Change on the Growing Season in the United States
(American Meteorological Society, 2011)nderstanding the effects of climate change on the vegetative growing season is key to quantifying future hydrologic water budget conditions. The U.S. Geological Survey modeled changes in future growing season length at 14 ... -
Evaluating Error Propagation in Coupled Land–Atmosphere Models
(American Meteorological Society, 2011)his study examines how land-use errors from the Land Transformation Model (LTM) propagate through to climate as simulated by the Regional Atmospheric Model System (RAMS). The authors conducted five simulations of regional ... -
Effects of Baseline Conditions on the Simulated Hydrologic Response to Projected Climate Change
(American Meteorological Society, 2011)hanges in temperature and precipitation projected from five general circulation models, using one late-twentieth-century and three twenty-first-century emission scenarios, were downscaled to three different baseline ... -
Flood Pulsing in the Sudd Wetland: Analysis of Seasonal Variations in Inundation and Evaporation in South Sudan
(American Meteorological Society, 2011)ocated on the Bahr el Jebel in South Sudan, the Sudd is one of the largest floodplain wetlands in the world. Seasonal inundation drives the hydrologic, geomorphological, and ecological processes, and the annual flood pulse ... -
Exploring Surface Biophysical-Climate Sensitivity to Tropical Deforestation Rates Using a GCM: A Feasibility Study
(American Meteorological Society, 2011)eforestation perturbs both biophysical and carbon feedbacks on climate. However, biophysical feedbacks operate at temporally immediate and spatially focused scales and thus may be sensitive to the rate of deforestation ... -
Simulations of Historical and Future Trends in Snowfall and Groundwater Recharge for Basins Draining to Long Island Sound
(American Meteorological Society, 2011)regional watershed model was developed for watersheds contributing to Long Island Sound, including the Connecticut River basin. The study region covers approximately 40 900 km2, extending from a moderate coastal climate ... -
