NOVEMBER 2003 AMERICAN METEOROLOGICAL SOCIETY | L ogistical and scientific operations in Antarctica are critically dependent on numerical weather guidance. The extreme, unforgiving environment amplifies the risks stemming from poor forecasts, while the sparse observing network often leaves forecasters heavily reliant on numerical weather prediction (NWP). To the operation of real-time mesoscale...

Fu), vkim@ This paper introduces a real-time optimization model that can be used by maintenance managers to develop and evaluate alternative resources allocation plans for winter road maintenance operations. The model takes int...

cold stress is one of the important factors which will reduce crop yield and fruit production in world. Early spring cooling and freezing weather is mostly. Possible this may considerable damage pistachio productions and farmer will lose most of their profit. Therefore study which show how pistachio plant cope freezing weather is valuable and important. The special role of amino acid in plant r...

Bright sunlight may create visual illusions that lead to driver error, including fallible distance judgment from aerial perspective. We tested whether the risk of a life-threatening motor vehicle crash was increased when driving in bright sunlight.This longitudinal, case-only, paired-comparison analysis evaluated patients hospitalized because of a motor vehicle crash between January 1, 1995 and...

name by Hanson is very common, especially in children, in Madras during the hot weather. Castellani, in his book on tropical diseases written in conjunction with Chalmers, and in his article on skin diseases in Byam and Archibald's " Practice of Medicine in the Tropics," describes the condition under the name pyosis and names four varieties, pyosis uiansoni, tropica, palmaris and corletti. The ...

including intraand interspecific interactions (i.e. competition, parasitism and predation), parental condition and behaviour, and weather (Newton 1998, Lima 2009). Temporal patterns, such as the date at which the nesting attempt started (i.e. time of breeding) or the stage of the nesting cycle (i.e. nest age), often influence nest survival (Grant et al. 2005, Lantz & Conway 2009, Nest survival ...

This paper reports preliminary and partial results of a flight experiment to address how General Aviation (GA) pilots use weather cues to make flight decisions. This research presents pilots with weather cue conditions typically available to GA pilots in visual meteorological conditions (VMC) and instrument meteorological conditions (IMC) today, as well as in IMC with a Graphical Weather Inform...

One of the major issues of increasing agricultural production, is adaptation of technology to specific climatic variables in cultivated areas. Knowing the weather and climatic condition and periodic yearly and multi-year changes of meteorological phenomena and deviations from normal values ​​are of major requirements of modern agriculture. In this study, daily, monthly and annual weather data o...

Traffic surveillance systems are interesting to many researchers to improve the traffic control and reduce the risk caused by accidents. In this area, many published works are only concerned about vehicle detection in normal conditions. The camera may vibrate due to wind or bridge movement. Detection and tracking of vehicles is a very difficult task when we have bad weather conditions in winter...
