RISSnowmelt-Related Flood Risk in Appalachia: First Estimates from a Historical Snow Climatology
Publisher: American Meteorological Society
Abstract: A first attempt has been made toward quantifying the risk of snowmelt-related flooding in the central and southern Appalachian Mountains of the United States (from 35° to 42°N). In the last decade, two major events occurred ...
Analysis of Cold Airmass Temperature Modification across the U.S. Great Plains as a Consequence of Snow Depth and Albedo
Publisher: American Meteorological Society
Abstract: The presence of snow cover has been shown to modify atmospheric conditions through much of the earth?s troposphere due to its radiative effects. Snow cover has garnered much attention in recent decades as a result of ...
Abrupt Changes in the Seasonal Cycle of North American Snow Cover
Publisher: American Meteorological Society
Abstract: Continental-scale snow cover extent has now been monitored from space for more than 20 yr in visible wavelengths. Here, the authors utilize weekly snow cover extent charts derived from such analyses to identify unusually ...
A Quantitative Approach to Evaluating the Effects of Snow Cover on Cold Airmass Temperatures across the U.S. Great Plains
Publisher: American Meteorological Society
Abstract: Over the past two decades a greater emphasis has been placed on the accuracy of the representation of snow cover?atmosphere interactions in weather and climate prediction models. Much of the attention centered upon snow ...
A Synoptic Climatological Approach to the Analysis of Lake-Effect Snowfall: Potential Forecasting Applications
Publisher: American Meteorological Society
Abstract: Due to their mesoscale nature, forecasting lake-effect snowfall events is very difficult but extremely important to the inhabitants of those regions subject to this type of severe winter weather. Such is the case along the ...
The Pacific/North American Teleconnection Pattern and United States Climate. Part II: Temporal Characteristics and Index Specification
Publisher: American Meteorological Society
Abstract: The PNA teleconnection index, a measure of the strength and phase of the Pacific/North American teleconnection pattern, is used to examine changes in the midtropospheric flow over North America on decadal, interannual, and ...
The Association between Extremes in North American Snow Cover Extent and United States Temperatures
Publisher: American Meteorological Society
Abstract: The association between satellite-derived North American snow cover extent and United States winter (December, January, February) temperature is examined. The results indicate that winter months evidencing extreme positive ...
Great Lakes Basin Snow-Cover Ablation and Synoptic-Scale Circulation
Publisher: American Meteorological Society
Abstract: AbstractSynoptic-scale atmospheric conditions play a critical role in determining the frequency and intensity of snow-cover-ablation events. Using a synoptic weather-classification technique, distinct regional circulation ...
A Teleconnection between Forced Great Plains Snow Cover and European Winter Climate
Publisher: American Meteorological Society
Abstract: Anomalies in Siberian snow cover have been shown to affect Eurasian winter climate through the North Atlantic Oscillation (NAO). The existence of a teleconnection between North American snow cover and the NAO is far less ...
Circulation Response to Eurasian versus North American Anomalous Snow Scenarios in the Northern Hemisphere with an AGCM Coupled to a Slab Ocean Model
Publisher: American Meteorological Society
Abstract: he difference between snow-covered and snow-free conditions is the most climatically significant natural seasonal change the land surface can experience. Most GCM studies investigating snow?atmosphere interactions have ...
