The characteristics of near-storm environments have been elucidated by several studies of observed soundings near reported tornadoes (Maddox 1976; Kerr and Darkow 1996), all soundings for multiple severe weather hazards during a complete year (Rasmussen and Blanchard 1998), or long-period samples of soundings associated with severe thunderstorms (Craven and Brooks 2004). Meanwhile, much attenti...

Severe atmospheric and road surface conditions on rural highways create a variety of transportation hazards. Variable Speed Limit (VSL) systems can mitigate the dangers caused by these conditions by displaying prudent maximum speed limits that reflect the prevailing atmospheric and road surface conditions. This paper discusses the design and implementation of a fuzzy rulebased system (FRBS) tha...

Catastrophic disasters afflicting human society are often triggered by tsunamis, earthquakes, widespread flooding, and weather and climate events. As human populations increasingly move into geographic areas affected by these earth system hazards, forecasting the onset of these large and damaging events has become increasingly urgent. In this paper we consider the fundamental problem of forecas...

The frequency of natural hazards has been increasing in the last decades in Europe and specifically in Mediterranean regions due to climate change. For example heavy precipitation events can lead to disasters through the interaction with exposed and vulnerable people and natural systems. It is therefore necessary a prevention planning to preserve human health and to reduce economic losses. Prev...

The potential impacts of climate change (CC) on Occupational Health and Safety (OHS) have been studied a little in tropical countries, while they received no attention in northern industrialized countries with a temperate climate. This work aimed to establish an overview of the potential links between CC and OHS in those countries and to determine research priorities for Quebec, Canada. A narra...

Resilience is widely seen as a desirable system property in environmental management. This paper explores the concept of resilience to natural hazards, using weather-related hazards in coastal megacities as an example. The paper draws on the wide literature on megacities, coastal hazards, hazard risk reduction strategies, and resilience within environmental management. Some analysts define resi...

Cold regions have their unique hazards such as hypothermia and frostbite. Hence, these hazards must be taken into account very early in the design phase. Moreover, risk analysis approaches should be updated to take into account the specific hazards of the Cold Climate region. There can be a high dependence between different cold region hazards and a combination of failures can happen during an ...

This paper compares ant colony optimization (ACO) and evolutionary multi-objective optimization (EMO) for the weather avoidance in a free flight environment. The problem involves a number of potentially conflicting objectives such as minimizing deviations, weather avoidance, minimizing distance traveled and hard constraints like aircraft performance. Therefore, we modeled the problem as a multi...

For monitoring of the Earth thousands of satellites have been sent into space on missions to collect data related different spheres of the Earth investigations and studies. Today, the ability to forecast weather, climate, and natural hazards, environmental monitoring and ecological issues depend critically on these satellite-based observations. Based on this data it is possible to gather satell...
