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...

An observational study of the energetics and dynamical aspects of GATE cloud clusters

Creator:: Wang, Jough-tai
Abstract:: Thermodynamical and dynamical aspects of tropical cloud clusters are studied using data from the GARP Atlantic Tropical Experiment (GATE). The data set used in this study is a three-dimensional gridded set of upper-air analyses constructed by Ooyama and Chu (Hurricane Research Division, AOML/NOAA and SSEC-University of Wisconsin) for wind data...

An observational study of the wind fields associated with GATE cloud clusters

Creator:: Tollerud, Edward I.
Abstract:: The wind and thermodynamic fields associated with eastern Atlantic cloud clusters are studied using radiosonde data from the Global Atmospheric Research Program Atlantic Tropical Experiment (GATE). These data are from the gridded set of winds prepared by Dr. Katsuyuki Ooyama (AOML-NOAA) and Dr. Jan-Hwa Chu (SSEC, University of Wisconsin, Madison)...

Surface heat flux estimates from NCAR electra data over the pacific warm pool during TOGA COARE

Creator:: Greiser, Christine M.
Abstract:: The warm pool region of the western tropical Pacific is of particular interest to atmospheric dynamics because it represents a significant source of energy to the atmosphere. A better understanding of heat transfer driven by mesoscale and turbulent circulations within this region could lead to improved global circulation models, and...

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....

Atmospheric boundary layer coupling to midlatitude mesoscale sea surface temperature anomalies

Creator:: Thum, Nicolai
Abstract:: This thesis examines the mechanisms that couple the monthly-averaged atmospheric boundary layer (ABL) to open-ocean sea surface temperature (SST) perturbations on scales of 50-500 km. The observed positive correlation between surface wind speed anomalies and SST anomalies is successfully simulated using the Weather Research and Forecasting (WRF) model. In numerical...

The use of conserved variables in the modeling and parameterization of shallow cumulus trade wind boundary layers

Creator:: Barbour, Philip L. (Philip Lee), 1960-
Abstract:: A time dependent model of the shallow, tropical convective boundary layer is developed and tested. To simplify the treatment of thermodynamic processes and return to first principles of physics, conserved quantities of entropy and total water density are used as primary model variables. In addition, a new shallow cumulus parameterization...

The long-term variations of east Asia jet stream in the wintertime

Creator:: Huang, Huei-I
Abstract:: Using rotated principal component analysis, 200mb wind data from the First GARP Global Experiment are analyzed in the East Asia winter monsoon region. It is found that there exist slowly eastward-moving disturbances with a wind-speed maximum embedded in the jet stream (jet streak). The implied vertical circulation that is transverse...

Air-sea heat exchange along the northern sea surface temperature front in the eastern tropical Pacific

Creator:: Thum, Nicolai
Abstract:: The atmospheric response to the oceanic forcing in the eastern Pacific along the northern equatorial sea surface temperature (SST) front is investigated in terms of sensible and latent heat flux during the 6-month period 28 July 1999 through 27 January 2000. Of particular interest is the atmospheric boundary layer (ABL)...
