We describe two of the most important teleconnections for Montana below, the El Niño - Southern Oscillation and the Pacific Decadal Oscillation.8 It is important to bear in mind that teleconnections are happening continually, and superimposed on each other as well as upon other long - term climate patterns.
Abstract — 2008 Climate and wildfires in the North American boreal forest... Climate controls the area burned through changing the dynamics of large - scale teleconnection patterns (Pacific Decadal Oscillation / El Niño Southern Oscillation and Arctic Oscillation, PDO / ENSO and AO) that control the frequency of blocking highs over the continent at different time scales......... Since the end of the Little Ice Age, the climate has been unusually moist and variable: large fire years have occurred in unusual years, fire frequency has decreased and fire — climate relationships have occurred at interannual to decadal time scales...... http://rstb.royalsocietypublishing.org/content/363/1501/2315.short ----------------------
In negative IPO phases, an El Niño — Southern Oscillation (ENSO)- precipitation teleconnection dominates Australian rainfall variability, but this connection fades and drought risk is increased during positive IPO phases [Power et al., 1999; Kiem and Franks, 2004; Cai et al., 2010].
Additional interests include the effects of the Pacific Ocean on the climate of British Columbia and how those effects are transmitted through such phenomena as El Niño / Southern Oscillation, the Pacific Decadal Oscillation, and the atmospheric teleconnections they induce.
«The authors write that «the El Niño - Southern Oscillation (ENSO) is a naturally occurring fluctuation,» whereby «on a timescale of two to seven years, the eastern equatorial Pacific climate varies between anomalously cold (La Niña) and warm (El Niño) conditions,» and that «these swings in temperature are accompanied by changes in the structure of the subsurface ocean, variability in the strength of the equatorial easterly trade winds, shifts in the position of atmospheric convection, and global teleconnection patterns associated with these changes that lead to variations in rainfall and weather patterns in many parts of the world,» which end up affecting «ecosystems, agriculture, freshwater supplies, hurricanes and other severe weather events worldwide.»»
Long - term variability in the El Nino Southern Oscillation and associated teleconnections.
For streamflow prediction, the ESP approach has very limited or no correlation skill beyond the months influenced by initial hydrologic conditions, while the CM - HPS has moderately better correlation skill, attributable to the enhanced temperature prediction skill that results from CanSIPS's ability to predict El Niño — Southern Oscillation (ENSO) and its teleconnections.
While researchers have identified teleconnections between El Niño - Southern Oscillation (ENSO) and extended winter precipitation extremes in North America using generalized extreme value (GEV) models, the regional form of the statistical relationship remains an open question.
Changes in solar output MAY initiate a response in the tropical Pacific that directly impacts the El Niño / Southern Oscillation and associated North Pacific teleconnections.»
This investigation will also identify origins of the potential predictability using composite analysis and large - scale teleconnections (Southern Oscillation, Pacific Decadal Oscillation, and North Atlantic Oscillation), providing the basis upon which seasonal predictions can be developed.
