Society is increasingly impacted by natural hazards which cause significant damage in economic and human terms. Many of these natural hazards are weather and climate related. Here, we show that North Atlantic atmospheric circulation regimes affect the propensity of extreme wind speeds in Europe. We also show evidence that extreme wind speeds are long-range dependent, follow a generalized Pareto...

In this study, a Route-Based Turbulent-Weather Avoidance Model (TWAM-R) is presented. TWAM-R improves a previously reported trajectory-based model which was tactical in nature. TWAM-R considers more strategic turbulence-avoidance decisions that are based on turbulence forecasts and pilot reports (PIREPs). TWAM-R identifies areas of reduced capacity and areas of potential hazards due to congesti...

In aviation, there is currently a lack of accurate and timely situational information, specifically weather data, which is essential when dealing with the unpredictable complexities that can arise while flying. For example, weather conditions that require immediate evasive action by the flight crew, such as isolated heavy rain, micro bursts, and atmospheric turbulence, require that the flight c...

Recent adverse weather events have questioned the stability of crop production systems. Here, we assessed vulnerability eleven major crops in France between 1959 and 2018 as a function climate, crafting novel hazard framework that combines exposure sensitivity to weather-related hazards. Exposure was defined frequency hazardous climate conditions. Sensitivity estimated by yield response single ...

all-weather, dayand-night imaging capability for mapping the Earth’s surface. Through interferometric synthetic aperture radar (InSAR) technique, radar imagery can be used to map Earth surface characteristics and measure land surface deformation at an unprecedented precision and spatial resolution. This article introduces the basics of radar and InSAR imaging, summarizes the revolution of InSAR...

Introduction Health care services for pregnant women and children are partially influenced by externalities such as climate change and environmental hazard health risks i.e., the vulnerabilities confounded within food insecurity and extreme weather events (floods) in drought prone geographical regions. The unhygienic conditions due to lack of adequate safe water and sanitation also compromised ...

Weather-related hazards are the result of interactions between the physical environment and the demographics of the community that experience them. Numerous studies have documented urban heat island (UHI) modification of cloud-to-ground lightning flash densities, but none have linked flashes to the underlying demographics. In this study, I compared flash and housing densities for 25 counties en...
