    Spatio-temporal modelling of extreme storms

    Get PDF
    A flexible spatio-temporal model is implemented to analyse extreme extra-tropical cyclones objectively identified over the Atlantic and Europe in 6-hourly re-analyses from 1979-2009. Spatial variation in the extremal properties of the cyclones is captured using a 150 cell spatial regularisation, latitude as a covariate, and spatial random effects. The North Atlantic Oscillation (NAO) is also used as a covariate and is found to have a significant effect on intensifying extremal storm behaviour, especially over Northern Europe and the Iberian peninsula. Estimates of lower bounds on minimum sea-level pressure are typically 10-50 hPa below the minimum values observed for historical storms with largest differences occurring when the NAO index is positive.Comment: Published in at http://dx.doi.org/10.1214/14-AOAS766 the Annals of Applied Statistics (http://www.imstat.org/aoas/) by the Institute of Mathematical Statistics (http://www.imstat.org

    Ford, A Village in the West Highlands of Scotland: A Case Study of Repopulation and Social Change in a Small Community

    Get PDF
    The Highlands of Scotland, like the southern Appalachians of the United States, have long been a problem area in Great Britain, troubled with a fading economy and loss of population. Most books about the region, however, are popular volumes that romanticize a bygone way of life. This study of Ford, a village of some 160 people in western Argyllshire, thus fills a gap in the literature and provides a look at the present realities of Scottish life. Although the Highlands are by no means a homogeneous region, Ford in its size and makeup is perhaps a representative rural settlement. John Stephenson, who conducted extensive interviews in the village during 1981, focuses his study on the theme of survival, on whether this particular village shows signs of enduring as a community of people bound together by common interests and situations. Though necessarily tentative, his conclusions are optimistic. Ford has shown a recent increase in population, consisting almost entirely of newcomers, and though its residents have now a more varied background, they seem to have a sense of place, of belonging to the village. This book will provide new insights not only for those interested in life in the Highlands but also for all those interested in small communities in other parts of the world. John B. Stephenson is professor of sociology and director of the Appalachian Center at the University of Kentucky. Captures the essence of social life in small communities operating on the margins of economic and social survival. —Contemporary Sociology This convincing portrait of the concerns of a group of contemporary Scots raises and even answers questions relevant in many other rural areas. —Choicehttps://uknowledge.uky.edu/upk_european_history/1029/thumbnail.jp

    Neutrino masses or new interactions

    Full text link
    Recent proposals to study the mass of the "electron" neutrino at a sensitivity of 0.3 eV can be used to place limits on the right handed and scalar charged currents at a level which improves on the present experimental limits. Indeed the neglect of the possibility of such interactions can lead to the inference of an incorrect value for the mass, as we illustrate.Comment: 12 pages and 3 figures.

    Neutrino clustering and the Z-burst model

    Full text link
    The possibility that the observed Ultra High Energy Cosmic Rays are generated by high energy neutrinos creating "Z-bursts" in resonant interactions with the background neutrinos has been proposed, but there are difficulties in generating enough events with reasonable incident neutrino fluxes. We point out that this difficulty is overcome if the background neutrinos have coalesced into "neutrino clouds" --- a possibility previously suggested by some of us in another context. The limitations that this mechanism for the generation of UHECRs places on the high energy neutrino flux, on the masses of the background neutrinos and the characteristics of the neutrino clouds are spelled out.Comment: 13 pages and 3 figures.
