Subseasonal variability in a two-level atmospheric general circulation model

Creator:

Kushnir, Yochanan

Abstract:

The dynamical processes which maintain atmospheric disturbances in regions of strong wintertime variability of the northern hemisphere are examined using data from a GCM simulation. Time series of the dependent variables and diabatic heating components from 10 Northern Hemisphere winters simulated by the Oregon State University two-level GCM are used....

The relationship of precipitation in the western United States to variations in the outgoing long-wave radiation field over the tropical Pacific : the role of the mid-latitude circulation

Creator:

Twining, David S.

Abstract:

The relationship between the outgoing long-wave radiation (OLR) field over the tropical Pacific and wintertime monthly precipitation for the western U. S. is investigated, using the mid-latitude upper-air circulation as an intermediary. Principal components (PC's) of the 500mb monthly averaged height field over the NE Pacific and western North America...
