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 thesis examines the applicability of a two-dimensional flow acceleration model to describe a terrain-induced flow perturbation as measured at Yaquina Head on the central Oregon coast. The geometry of Yaquina Head together with the upstream wind values were used in estimating hilltop winds. These estimates compare well with the...
Numerical simulation of the January and July global
climate with the OSU two-level atmospheric general circulation
model has generated time series of the global
distribution of selected climatic variables. Analyses of
these data for the kinetic energy and available potential
energy based on 31-day time mean statistics have been
made...
Ice cores are considered the gold standard for recording past climate and biogeochemical changes. However, gas records derived from ice core analysis have until now been largely limited to centennial and longer timescales because sufficient temporal resolution and analytical precision have been lacking, except during rare times when atmospheric concentrations...
The dynamical nature of atmospheric disturbances in
the Southern Hemisphere simulated by a two-level general
circulation (GCM) model is studied. Time series of the
dependent variables and diabatic heating components from
10 Southern Hemisphere winters (JJA) and summers (DJF)
simulated by the Oregon State University two-level GCM are
used. The...
