RISSummer Drought Patterns in Canada and the Relationship toGlobal Sea Surface Temperatures
Publisher: American Meteorological Society
Abstract: Canadian summer (June?August) Palmer Drought Severity Index (PDSI) variations and winter (December? February) global sea surface temperature (SST) variations are examined for the 63-yr period of 1940?2002. Extreme wet and ...
Skill of Seasonal Climate Forecasts in Canada Using Canonical Correlation Analysis
Publisher: American Meteorological Society
Abstract: An empirical system for forecasting 3-month mean surface temperature T and total precipitation P for Canada?canonical correlation analysis (CCA)?has been developed using the 1956?90 data period. The levels and sources of ...
Prediction of Seasonal Forest Fire Severity in Canada from Large-Scale Climate Patterns
Publisher: American Meteorological Society
Abstract: n empirical scheme for predicting the meteorological conditions that lead to summer forest fire severity for Canada using the multivariate singular value decomposition (SVD) has been developed for the 1953?2007 period. The ...
Modes of Interannual and Interdecadal Variability of Pacific SST
Publisher: American Meteorological Society
Abstract: The multichannel singular spectrum analysis has been used to characterize the spatio?temporal structures of interdecadal and interannual variability of SST over the Pacific Ocean from 20°S to 58°N. Using the Comprehensive ...
The Nonlinear Patterns of North American Winter Temperature and Precipitation Associated with ENSO
Publisher: American Meteorological Society
Abstract: Nonlinear projections of the tropical Pacific sea surface temperature anomalies (SSTAs) onto North American winter (November?March) surface air temperature (SAT) and precipitation anomalies have been performed using neural ...
Specifying Monthly Mean Surface Temperatures in Canada and Alaska from the 500 mb Height Field
Publisher: American Meteorological Society
Abstract: Specification equations for monthly mean air temperature anomalies at 68 surface stations in Canada and Alaska are derived by applying a forward selection screening procedure to simultaneous monthly mean 500 mb height ...
Regional Analysis of Northern Hemisphere 50 kPa Geopotential Heights from 1946 to 1985
Publisher: American Meteorological Society
Abstract: In Knox et al., the interannual variation of the Northern Hemisphere 50 kPa geopotential height field averaged between 30° and 80°N was investigated for the 40-year period from 1946 to 1985. We presented strong statistical ...
Canadian Precipitation Patterns Associated with the Southern Oscillation
Publisher: American Meteorological Society
Abstract: Precipitation responses over Canada associated with the two extreme phases of the Southern Oscillation (SO), namely El Niño and La Niña, are identified. Using the best available precipitation data from 1911 to 1994, both ...
Secular Variation of Northern Hemisphere 50 kPa Geopotential Height
Publisher: American Meteorological Society
Abstract: There is accumulating evidence in the literature that different short-period climate regimes (subclimates) may have characterized the Northern Hemisphere during the past 40 years. We, therefore, investigate the 40-yr record ...
Seasonal-to-Decadal Predictability and Prediction of North American Climate—The Atlantic Influence
Publisher: American Meteorological Society
Abstract: The question of the impact of the Atlantic on North American (NA) seasonal prediction skill and predictability is examined. Basic material is collected from the literature, a review of seasonal forecast procedures in Canada ...
