The development of forecast techniques for wave and surf conditions over the bars in the Columbia River Mouth and at the entrance to Yaquina Bay : final report
This investigation has been carried out primarily to define the Columbia
River bar crossing problem, to determine the physical factors involved in
hazardous transit developments, and to develop a method for predicting
hazardous bar transit conditions sufficiently in advance to allow proper
safety precautions to be effected.
Actual records of periods of bar closure for the years 1963 - 1969,
as determined by the Columbia River Bar Pilots Association, provide a firm
foundation for the entry into this study. Meteorological and oceanographic
conditions leading to the closures, as well as those occurring during
periods of closure, are being analyzed to identify the more immediate
causes for such situations and also to determine the nature of their temporal
and spatial evolution. Much of the background material necessary for this
study has been compiled, and case histories on conditions leading to closure
circumstances are being prepared to determine the various types of
situation development
On the changes in number and intensity of North Atlantic tropical cyclones
Bayesian statistical models were developed for the number of tropical
cyclones and the rate at which these cyclones became hurricanes in the North
Atlantic. We find that, controlling for the cold tongue index and the North
Atlantic oscillation index, there is high probability that the number of
cyclones has increased in the past thirty years; but the rate at which these
storms become hurricanes appears to be constant. We also investigate storm
intensity by measuring the distribution of individual storm lifetime in days,
storm track length, and Emanuel's power dissiptation index. We find little
evidence that the distribution of individual storm intensity is changing
through time. Any increase in cumulative yearly storm intensity and potential
destructiveness, therefore, is due to the increasing number of storms and not
due to any increase in the intensity of individual storms.Comment: 24 pages, 9 figure
Dependencies in language: On the causal ontology of linguistic systems
Dependency is a fundamental concept in the analysis of linguistic systems. The many if-then statements offered in typology and grammar-writing imply a causally real notion of dependency that is central to the claim being madeāusually with reference to widely varying timescales and types of processes. But despite the importance of the concept of dependency in our work, its nature is seldom defined or made explicit. This book brings together experts on language, representing descriptive linguistics, language typology, functional/cognitive linguistics, cognitive science, research on gesture and other semiotic systems, developmental psychology, psycholinguistics, and linguistic anthropology to address the following question: What kinds of dependencies exist among language-related systems, and how do we define and explain them in natural, causal terms
