The Effect of Zonally Asymmetric Ozone Heating on the Northern Hemisphere Winter Polar Stratosphere

[1] Previous modeling studies have found significant differences in winter extratropical stratospheric temperatures depending on the presence or absence of zonally asymmetric ozone heating (ZAOH), yet the physical mechanism causing these differences has not been fully explained. The present study describes the effect of ZAOH on the dynamics of the Northern Hemisphere extratropical stratosphere using an ensemble of free-running atmospheric general circulation model simulations over the 1 December - 31 March period. We find that the simulations including ZAOH produce a significantly warmer and weaker stratospheric polar vortex in mid-February due to more frequent major stratospheric sudden warmings compared to the simulations using only zonal mean ozone heating. This is due to regions of enhanced Eliassen-Palm flux convergence found in the region between 40°N–70°N latitude and 10–0.05 hPa. These results are consistent with changes in the propagation of planetary waves in the presence of ZAOH predicted by an ozone-modified refractive index

Use of Soil Surveys in the Identification of Floodplains

Author Institution: State Soil Scientist, Soil Conservation Service, U. S. Dept. of Agriculture, Columbus, Ohio 43215The frequency of flooding and depth of flood waters on alluvial soils and soils on stream terraces, was evaluated in selected sections of the Great Miami River Valley and tributaries in Montgomery and Preble Counties, Ohio. The boundaries of the highest elevations of flood waters during the floods of 1913 and 1959 were compared to the boundaries of alluvial soils and soils on stream terraces. Essentially all of the alluvial soils were inundated in both floods. About forty percent of the area of terrace soils were inundated in 1913, but less than ten percent in 1959. It is estimated that the frequency of flooding of alluvial soils is more frequent than once in forty years, and that only the very lowest portions of the terraces are inundated during floods of that frequency. Analysis of the data indicate soil surveys can be used to delineate those areas where the probability of flooding is greatest, and thus where the need for land use restrictions, such as zoning, to minimize damages due to flooding is most urgent

Critical Current Peaks at 3BΦ3B_{\Phi} in Superconductors with Columnar Defects: Recrystalizing the Interstitial Glass

The role of commensurability and the interplay of correlated disorder and interactions on vortex dynamics in the presence of columnar pins is studied via molecular dynamics simulations. Simulations of dynamics reveal substantial caging effects and a non-monotonic dependence of the critical current with enhancements near integer values of the matching field $B_{\phi}$ and $3B_{\phi}$ in agreement with experiments on the cuprates. We find qualitative differences in the phase diagram for small and large values of the matching field.Comment: 5 pages, 4 figures (3 color

Close to the Source

Abstract Close to the Source is comprised of a series of nonfiction vignettes about the artisan, agricultural, and culinary methods of Italy. In Close to the Source the human relationship with nature, food, and art is reexamined while a series of rich characters help bring the material to life. Through interviews, research, and first-hand experiences, the author attempts to archive fading artisan and food-related techniques and rituals. In the process, a cultural critique about the importance of the practical arts in contemporary times emerges. The thesis contains four sections: Terra/Land; Art and Artisans; Pane/Bread; and Compagnia/Company

Language Fluency Project: An Investigation Into the Training and Development of Socialised Language With Adolescents With a Mental Handicap

Since the publication of the Warnock Report (1978) on children's special educational needs, special schooling has taken a new direction. Some authorities have even gone as far as to abolish their special schools, while others have implemented greater integration between special and ordinary schools. In almost all instances a greater challenge has been given to children hitherto labelled as handicapped, either physically or mentally, or both. They are now expected to cope in a greater variety of educational settings. Such demands highlight the need for more action research in the social and communication skills of persons of all ages with a mental handicap. The Language Fluency Project, hereafter referred to as LFP, was set up to investigate the development and training of socialised language in adolescents with a mental handicap, their linguistic behaviour in a conversation situation, and the development of verbal and social facility
