A stochastic precipitation event model for use in erosion simulations

Creator:: Istok, J. D.
Abstract:: Mathematical models of the precipitation process are needed to effectively use historical precipitation data in the design and planning of engineering projects and for analysis of watershed runoff behavior. Existing simple models based on the assumptions of independent, identically-distributed random variables are insufficient to describe several features of the historical...

Evaluation of alternative Markovian models for precipitation occurrence in Oregon

Creator:: Adotevi-Akue, George Modesto
Abstract:: Precipitation occurrence in three winter periods and three summer periods is examined for two Oregon stations: Seaside and Squaw Butte. The winter periods are January, February, and the interval January 15 to February 20. The summer periods are July, August, and the interval July 10 to August 15. The two...

Regional Scale Modeling of Climate, Cryosphere, and Freshwater Discharge in Changing Coastal Mountain Environments

Creator:: Beamer, Jordan P.
Abstract:: The glaciated coastal mountain watersheds that drain into the Gulf of Alaska (GOA) provide a model laboratory to explore the challenges of hydrological modeling and study the impact of climate and glacier cover change on regional hydrology. The region is data-sparse and contains a complex assemblage of topography and land...

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...

Modeled and observed longwave radiances at the top of the atmosphere

Creator:: Stone, Kenneth A.
Abstract:: One method of estimating the longwave radiative heating of the atmosphere is to combine satellite observations of emitted radiances with those computed from synoptic temperature and humidity profiles. Modeled and observed radiances are brought into agreement by altering cloud properties or even by adjusting the temperature and water vapor profiles....

The effects of clouds on transient baroclinic eddies in a Mars General Circulation Model

Creator:: Rucker, Michael S.
Abstract:: The low-level baroclinic eddy activity seen in the NASA Ames Mars General Circulation Model (MGCM) for simulations under three annual dust cycles are characterized. Simulations were conducted with both radiatively active and radiatively inert clouds (RAC and non-RAC, respectively) for 11 continuous annual cycles for each dust case. Model results...

Long-term momentum and heat balances and turbulent mixing in the upper equatorial Pacific Ocean

Creator:: Luan, Shusheng
Resource Type:: Dissertation

Diurnal wind-driven processes on the northern Monterey Bay inner shelf

Creator:: Suanda, Sutara H.
Abstract:: In the summer of 2007, a biophysical experiment was conducted to identify physical processes that determine the delivery of invertebrate larvae and juvenile rockfish to rocky intertidal and kelp forest communities in northern Monterey Bay, California. The experiment was sponsored by the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO)...

Integrating real-time weather data with dynamic crop development models

Creator:: Donaldson, William S.
Abstract:: Crop development models are commonly used in research. However, their use as crop management tools for growers is rare. Decision support systems (DSS), which combine crop models with expert systems, are being developed to provide management assistance to growers. Researchers at Oregon State University are in the process of developing...
