Abstract:
[Source: NOAA Climate Prediction Center, http://www.cpc.ncep.noaa.gov/ ] The North Pacific pattern is prominent from March through July. This pattern consists of a primary anomaly center which spans the central latitudes of the western and central North Pacific, and weaker anomaly region of opposite sign which spans eastern Siberia, Alaska and the intermountain region of North America. Overall, pronounced positive phases of the NP pattern are associated with a southward shift and intensification of the Pacific jet stream from eastern Asia to the eastern North Pacific, followed downstream by an enhanced anticyclonic circulation over western North America, and by an enhanced cyclonic circulation over the southeastern United States. Pronounced negative phases of the NP pattern are associated with circulation anomalies of opposite sign in these regions. Bell and Janowiak (1995) recently noted that a positive phase of the NP pattern reflects one of the preferred responses of the extratropical atmospheric circulation to ENSO during the Northern Hemisphere spring. This response was particularly evident during the 1992 and 1993 spring seasons, when a prolonged positive phase of the NP pattern dominated the circulation. Bell and Janowiak also note that the atmospheric circulation during the several month period prior to the onset of the Midwest floods of June-July 1993 was dominated by the most pronounced and persistent positive phase of the NP pattern in the historical record. Their study concluded that these conditions were indirectly important to the onset and overall magnitude of the floods, since they fostered an anomalously intense storm track over the midlatitudes of the North Pacific. Dramatic changes in this storm track during June then ultimately initiated the Midwest floods.
