A Seasonal Shift in the Frequency of Extreme Hydrological Events in Southern New York State
Publisher: American Meteorological Society
Abstract: he recent sequence of extreme hydrological events across the eastern United States (e.g., Hurricane Irene in August 2011, Tropical Storm Lee in September 2011, and Hurricane Sandy in October 2012), which led to unprecedented ...
Physical Mechanisms Linking the Winter Pacific–North American Teleconnection Pattern to Spring North American Snow Depth
Publisher: American Meteorological Society
Abstract: The wintertime Pacific?North American (PNA) teleconnection pattern has previously been shown to influence springtime snow conditions over portions of North America. This paper develops a more complete physical understanding ...
North American Temperature, Snowfall, and Snow-Depth Response to Winter Climate Modes
Publisher: American Meteorological Society
Abstract: The snowpack is an important seasonal surface water storage reservoir that affects the availability of water resources during the spring and summer seasons in mid?high latitudes. Not surprisingly, interannual variations ...
The Seasonal Nature of Extreme Hydrological Events in the Northeastern United States
Publisher: American Meteorological Society
Abstract: ecent analyses of extreme hydrological events across the United States, including those summarized in the recent U.S. Third National Climate Assessment (May 2014), show that extremely large (extreme) precipitation and ...
The Role of Boundary Conditions in AMIP-2 Simulations of the NAO
Publisher: American Meteorological Society
Abstract: The simulated North Atlantic Oscillation (NAO) teleconnection patterns and their interannual variability are evaluated from a suite of atmospheric models participating in the second phase of the Atmospheric Model Intercomparison ...
Snow Mass over North America: Observations and Results from the Second Phase of the Atmospheric Model Intercomparison Project
Publisher: American Meteorological Society
Abstract: Eighteen global atmospheric general circulation models (AGCMs) participating in the second phase of the Atmospheric Model Intercomparison Project (AMIP-2) are evaluated for their ability to simulate the observed spatial ...
Evaluating Stochastic Precipitation Generators for Climate Change Impact Studies of New York City’s Primary Water Supply
Publisher: American Meteorological Society
Abstract: atersheds located in the Catskill Mountains of southeastern New York State contribute about 90% of the water to the New York City water supply system. Recent studies show that this region is experiencing increasing trends ...
Relative importance of internal climate variability versus anthropogenic climate change in global climate change
Publisher: American Meteorological Society
Abstract: To better understand the role of internal climate variability (ICV) in climate change impact studies, this study quantifies the importance of ICV (defined as the inter-member variability of a single model initial-condition ...
Track and Circulation Analysis of Tropical and Extratropical Cyclones that Cause Strong Precipitation and Streamflow Events in the New York City Watershed
Publisher: American Meteorological Society
Abstract: AbstractThe top 100 basin-scale 1-day precipitation, multiday precipitation, and 1-day streamflow events from 1950 to 2012 are examined for the Ashokan reservoir, a key water source for New York City. Through a cyclone ...
