A climatology of the mid-Atlantic winter-time jet stream
Robert Junod, Millersville Univ., Millersville, PA; and S. R. Baxter and D. S. Yalda
Jet streams are driving factors for weather in the midlatitudes. A 2008 study by Archer and Calderia published in the Geophysical Research Letters concluded that there has been a significant change in jet stream strength and position in both hemispheres from 1979-2001. One result from Archer's and Calderia's study that is of interest to our research is that the jet stream in the Northern Hemisphere has also weakened. This study looks to assess regional winter-time jet stream variability from 1970-2008 over the mid-Atlantic region. Observational data from the Integrated Global Radiosonde Archive was used to compile an upper- level wind climatology during the November-March period. This climatology was used to determine changes in the winter-time jet stream location and strength over the mid-Atlantic region. This presentation will provide an overview of the results of this climatological study in addition to possible linkages to the effect of the regional jet stream variability on the regional climate.
