Climate-Driven Variability and Trends in Mountain Snowpack in Western North America
Publisher: American Meteorological Society
Abstract: Records of 1 April snow water equivalent (SWE) are examined here using multiple linear regression against reference time series of temperature and precipitation. This method permits 1) an examination of the separate roles ...
The Response of Northern Hemisphere Snow Cover to a Changing Climate
Publisher: American Meteorological Society
Abstract: A snowpack model sensitivity study, observed changes of snow cover in the NOAA satellite dataset, and snow cover simulations from the Coupled Model Intercomparison Project phase 3 (CMIP3) multimodel dataset are used to ...
Three Recent Flavors of Drought in the Pacific Northwest
Publisher: American Meteorological Society
Abstract: In common with much of the western United States, the Pacific Northwest (defined in this paper as Washington and Oregon) has experienced an unusual number of droughts in the past decade. This paper describes three of these ...
Evaluation of WRF and HadRM Mesoscale Climate Simulations over the U.S. Pacific Northwest
Publisher: American Meteorological Society
Abstract: This work compares the Weather Research and Forecasting (WRF) and Hadley Centre Regional Model (HadRM) simulations with the observed daily maximum and minimum temperature (Tmax and Tmin) and precipitation at Historical ...
Seasonal Climate Variability and Change in the Pacific Northwest of the United States
Publisher: American Meteorological Society
Abstract: bserved changes in climate of the U.S. Pacific Northwest since the early twentieth century were examined using four different datasets. Annual mean temperature increased by approximately 0.6°?0.8°C from 1901 to 2012, with ...
Stratospheric Flow during Two Recent Winters Simulated by a Mechanistic Model
Publisher: American Meteorological Society
Abstract: The authors have used a spectral, primitive equation mechanistic model of the stratosphere and mesosphere to simulate observed stratospheric flow through the winters of 1991?92 and 1994?95 by forcing the model at 100 hPa ...
DECLINING MOUNTAIN SNOWPACK IN WESTERN NORTH AMERICA*
Publisher: American Meteorological Society
Abstract: In western North America, snow provides crucial storage of winter precipitation, effectively transferring water from the relatively wet winter season to the typically dry summers. Manual and telemetered measurements of ...
Detection and Attribution of Observed Changes in Northern Hemisphere Spring Snow Cover
Publisher: American Meteorological Society
Abstract: ignificant declines in spring Northern Hemisphere (NH) snow cover extent (SCE) have been observed over the last five decades. As one step toward understanding the causes of this decline, an optimal fingerprinting technique ...
