The majority of general aviation (GA) accidents involving adverse weather result in fatalities. Considering the high weather-related fatality rate among GA flight operations, it is imperative to ensure that pilots all experience levels can incorporate available information into their planning. In past decade, product development has incorporated increasing automation, which led generation high-...

Air traffic delays in the U.S. are problematic and often attributable to convective (thunderstorms) weather. Air traffic management is complex, dynamic, and influenced by many factors such as projected high volume of departures and uncertain forecast convective weather at airports and in the airspace. To support the complexities of making a re-route decision, which is one solution to mitigate a...

A geospatial visualization tool that is capable of visualizing weather data in conjunction with the terrain and object data typical of GIS visualization tools provides an important advancement in the study severe weather formation by providing a tool for weather scientists to study of the impact of land topography and human changes. In particular, unlike the plains region, tornados in the South...

This study examined select endocrine and metabolic responses of Norwegian soldiers to performing military physical training in an arctic field setting which involved cold exposure. Also, the impact on nocturnal shelter conditions on the physiological responses was investigated. A field based group (EXP, n = 17) lived in tents and a garrison group (CON, n = 16) lived in barracks for 10 days whil...

Mobile transactions for updating spatial data are long-lived transactions that update local copies of the mobile platforms on disconnection. Since a mobile transaction is physically separated from its global transaction, the concurrent updates of mobile transactions should be merged into the global database after committing. Validation-based schemes, which are well-known to be appropriate for m...

A medical-meteorological weather assessment using hybrid spatial classification of synoptic and meteorological data was done. Empirical models for assessment as well as for forecast of medical-meteorological weather type at the seaside climatic zone in Palanga were developed. It was based on the data of meteofactors (atmospheric pressure, relative humidity, temperature, oxygen density in atmosp...

Recently, the number of unusual extreme weather that causes natural disasters is increasing, and accompanying phenomena such as local heavy rainstorms, tornado, and gust fronts have caused an immediate and often devastating impact on a broad range of human activities. Weather radar has played an important role to survey those meteorological phenomena associated with rainfall and to mitigate mos...

Ahvaz can be regarded as one of the most polluted cities in the world in terms of air pollution. Successive years of drought and weather conditions in recent years have resulted in particulate matter (PM10) concentration in Ahvaz. In this study, using probability distribution techniques, an appropriate threshold to identify the PM10 maximum extreme concentrations (MEC) has been detected. Based ...
