Nowcasting Thunderstorms for Munich Airport

The successful demonstration and assessment of the DLR thunderstorm nowcasting algorithms at Munich Airport during two campaigns in the summers of 2010 and 2011 are described. The algorithms Cb-TRAM and Rad-TRAM, that detect, monitor, and forecast up to one hour (nowcast) thunderstorm cells from satellite and radar data, run in real time and provided new thunderstorm products for users at the airport. The products were presented on displays the users were already familiar with as well as on webpages designed by DLR. On the webpages, also additional information like measurements with DLR’s polarimetric radar and model forecasts was shown. Moreover, thunderstorm warnings were is-sued and sent via email to the users whenever a thunderstorm was detected in the terminal manoeu-vring area of the airport of Munich. The nowcasting skills of Rad-TRAM and Cb-TRAM are encouraging, especially for lead times up to 30 minutes, and the user feedback on the DLR thunderstorm products was very positive. The Rad-TRAM and Cb-TRAM products provide a good overview on the situation and its future development, and the thunderstorm warnings were very helpful for the collaborative decision making at the airport. However, some suggestions for improvements were made like the demand for nowcasts beyond one hour. This will be considered within the integrated weather forecast system, WxFUSION, which has been further developed during the campaigns

Dr. Billy Taylor, “America's Classical Music,” and the Role of the Jazz Ambassador

The idea of jazz as “America's classical music” has become a powerful way of defining the music, asserting its national and artistic value, and shaping its scholarly study. The present article provides a history of this idea through a close analysis of its primary theorist and most visible spokesperson, Dr. Billy Taylor. It argues that the idea was not a neoclassical and conservative product of the 1980s, but had important roots in the Black Arts imperatives of the later 1960s and early 1970s. It suggests that Taylor initially made the idea work inventively and productively in a variety of contexts, especially through his community arts project Jazzmobile, but that these contexts diverged as his public profile was stretched thin across and beyond the United States. The idea's disintegration into clichéd ubiquity in the mid-1980s then provides a critical perspective on the idea of the “jazz renaissance,” and an opportunity to consider the role of the jazz ambassador in the context of debates about African American intellectuals.This is the author accepted manuscript.

Cb-TRAM: Tracking and monitoring severe convection from onset over rapid development to mature phase using multi-channel Meteosat-8 SEVIRI data

Cb-TRAM is a new fully automated tracking and nowcasting algorithm. Intense convective cells are detected, tracked and discriminated with respect to onset, rapid development, and mature phase. Finally, short range forecasts are provided. The detection is based on Meteosat-8 SEVIRI (Spinning Enhanced Visible and Infra-Red Imager) data from the broad band high resolution visible, infra-red 6.2 micrometer (water vapour), and the infra-red 10.8 micrometer channels. Areas of convection initiation, of rapid vertical development, and mature thunderstorm cells (cumulonimbus Cb) are identified. For the latter, tropopause temperature data from ECMWF operational model analyses is utilised as an adaptive detection criterion. The tracking is based on geographical overlap between current detections and first guess patterns of cells detected in preceeding time steps. The first guess patterns as well as the short range forecasts are obtained with the aid of a new image matching algorithm providing complete fields of approximate differential cloud motion. Based on the so called pyramid matcher an interpolation and extrapolation technique is presented which can also be used to generate synthetic intermediate data fields between two known fields as well as nowcasts of motion and development of detected areas. Examples of application are presented for thunderstorm tracks over the Mediterranean

Democracy and Expertise in the Lippmann-Terman Controversy

Historians often interpret American political thought in the early twentieth century through an opposition between the technocratic power of expertise and the deliberative promise of democracy, respectively represented by Walter Lippmann and John Dewey. This article explores Lippmann's concurrent controversy with Lewis Terman about intelligence testing, in which Dewey also intervened. It argues that the Lippmann–Terman controversy dramatized and developed a range of ideas about the politics of expertise in a democracy, which centered on explaining how democratic citizens might engage with and control the authority of experts. It concludes by examining the controversy's influence on democratic theory

Ordinary People and the 1979 Royal Commission on the NHS

In June 1979, the Royal Commission on the National Health Service published its report. Chaired by Sir Alec Merrison, the Commission covered England, Scotland, Wales and Northern Ireland. In 1976, the Royal Commission published and broadcast calls, asking the public to put forward their views on the NHS. In response, they received around 2,460 written evidence submissions, held fifty-eight oral evidence sessions, and met with about 2,800 individuals. In soliciting evidence, the Commission called on people to comment on their experience of the health service, submit that experience as evidence, and contribute suggestions for the NHS’s improvement. These submissions of evidence, mostly in the form of letters written to Merrison, are rich and revealing sources. While NHS staff, trade unionists, and professional organizations were invited to contribute their perspectives, patients and other non-clinical members of the British public also penned letters. In this article, I use the evidence submitted by self-proclaimed ‘ordinary’ people to contribute to emerging discussions about post-war British citizenship, and its intimate or quotidian relationship to the welfare state. I use these submissions as evidence for popular anxieties in the 1970s, and to explore the various ways that British citizens experienced and engaged with the NHS; investigate how they felt about its services; and consider the affective and political function of complaint

Clio in the Operating Theatre: Historical Research, Emotional Health, and Surgical Training in Contemporary Britain.

Drawing on my experience working as a postdoctoral research and engagement fellow on the Wellcome Trust-funded project, Surgery & Emotion, this article reflects on this innovative model of historical research and professional engagement, explores the challenges posed by crossing disciplinary boundaries, and interrogates the practical and theoretical utility of bringing historical research into the operating theatre. How do surgeons specifically engage with the history of their profession? What can the history of emotions offer to the training of medical students and surgeons? What obstacles interfere in this type of cross-disciplinary engagement? What peculiar opportunities and challenges do the United Kingdom higher education system and National Health Service pose to the teaching of medical history in clinical settings? Bringing Clio into the operating theatre provides surgeons with an alternative narrative to that which they have come to expect about the emotions they ought to feel and express in their work. It allows them to explore the high feelings of their professional lives at a remove and offers an array of possible solutions to the current emotional health crisis in British medicine. History allows surgeons to imagine an alternative world: one where the pervasive and persistent models of emotional detachment - damaging to both patient experience and professional wellbeing - dissolve
