Spencer H. Wood
PURPOSE OF STUDY To document the peak stages of flood flow of Hurricane Mitch in a tropical rain forest river, and their relation to channel morphology. These flood stages were the highest of the century on this river according to indigenous people living along the river bank.
The Influence Of Wave– And Zonal Mean–Ozone Feedbacks On The Quasi-Biennial Oscillation, Eugene Cordero, Terrence R. Nathan
The Influence Of Wave– And Zonal Mean–Ozone Feedbacks On The Quasi-Biennial Oscillation, Eugene Cordero, Terrence R. Nathan
Eugene C. Cordero
The effects of wave and zonal mean ozone heating on the evolution of the quasi-biennial oscillation (QBO) are examined using a two-dimensional mechanistic model of the equatorial stratosphere. The model atmosphere is governed by coupled equations for the zonal mean and (linear) wave fields of ozone, temperature, and wind, and is driven by specifying the amplitudes of a Kelvin wave and a Rossby–gravity wave at the lower boundary. Wave–mean flow interactions are accounted for in the model, but not wave–wave interactions.
A reference simulation (RS) of the QBO, in which ozone feedbacks are neglected, is carried out and the results …
Effects Of Planetary Wave-Breaking On The Seasonal Variation Of Total Column Ozone, Terrence R. Nathan, Eugene C. Cordero, Long Li, Donald J. Wuebbles
Effects Of Planetary Wave-Breaking On The Seasonal Variation Of Total Column Ozone, Terrence R. Nathan, Eugene C. Cordero, Long Li, Donald J. Wuebbles
Eugene C. Cordero
The effects of planetary wave breaking on the seasonal variation of total column ozone are investigated using a zonally averaged chemical-radiative-transport model of the atmosphere. The planetary wave breaking effects of zonal wavenumbers k=1 and k=2 are significant in the middle latitude stratosphere during Northern Hemisphere (NH) winter, whereas only wave k=1 is important during Southern Hemisphere (SH) winter. The mixing and induced meridional circulation due to the planetary wave breaking increases the seasonal variation of total column ozone in NH (SH) middle latitudes by ∼20% (∼10%).

Barry A. Palynchuk PhD
In late June 1998, a major storm event occurred in the Adirondack Mountains in the vicinity of Keeseville, New York about 150 miles north of Albany. This storm resulted in unprecedented damage to the Canadian Pacific Railway (CPR) Canadian Mainline along the shores of Lake Champlain. The storm caused 14 major embankment failures and washouts, numerous minor failures, severe bridge foundation scour and a major mainline derailment.
Moving The Climate Change Debate From Models To Proposed Legislation: Lessons From State Experience, John C. Dernbach
Moving The Climate Change Debate From Models To Proposed Legislation: Lessons From State Experience, John C. Dernbach
John C. Dernbach
This Article assesses the relationship between state climate change mitigation measures and potential national climate change legislation. It describes and evaluates eleven different legal and policy tools being employed by states. These are: customer choice of electricity providers, environmental labeling requirements for electricity sources, building codes requiring energy efficiency, demand-side management, system benefit charges, cap-and-trade programs, tax credits, net metering, planning and siting preferences for renewable energy facilities, CO2 limits for new power plants, and renewable energy portfolio standards. Two broad conclusions emerge from this analysis. First, these tools have considerable potential to reduce greenhouse gas emissions. They achieve reductions …
