On average, about a thousand tornadoes hit the United States every year. Three out of every four tornadoes in the world, occur in the United States. They damage life and property in their path and they often hit with very little, sometimes no warning. Tornadoes cause approximately 70 fatalities and 1,500 injuries in US every year. The interest of this study is to find whether the fatalities and...

The winners of the poster prizes are below Kelsey Mulder presenting her poster We present a climatology for tornadoes in the British Isles, defined here as England, Scotland, Wales, Northern Ireland, Republic of Ireland, Channel Islands, and the Isle of Man. The climatology includes the geographic distribution, annual and diurnal cycles, seasonality, intensities, and occurrence of outbreaks in ...

UDP traffic is a part of the aggregate traffic over InterPlaNetary Internet backbone links, which includes planet images and multimedia data from some scientific observations. Existing rate control schemes cannot solve the rate control problem in InterPlaNetary Internet which is characterized by extremely long propagation delays, high link errors, asymmetrical bandwidth, and blackouts. In this ...

Satellite radar and radiometer data show that subtropical South America has the world’s deepest convective storms, robust mesoscale convective systems, and very frequent large hail. We determine severe weather characteristics for the most intense precipitation features seen by satellite in this region. In summer, hail and lightning concentrate over the foothills of western Argentina. Lightning ...

The risk of trains being hit by tornadoes in China continues to increase due the increasing density railway lines and shortening train departure intervals probability extreme weather phenomena caused global climate change. If a is tornado, it will cause huge casualties economic losses, so necessary investigate tornado-induced effects on trains. A series rigid-model wind pressure measurement tes...

Recently, a new kernel for modelling and virtual experimentation (i.e. any evaluation of a model) in the domain of water quality management was developed. This kernel was named “Tornado” and will be included in the new generation of the WEST product family, as well as in several other products (e.g. DHI’s MOUSE-TRAP) and projects. Most important issues during development were versatility and ef...

This study introduces a system that objectively assesses severe thunderstormnowcast probabilities based on hourly mesoscale data across the contiguous United States during the period from 2006 to 2014. Previous studies have evaluated the diagnostic utility of parameters in characterizing severe thunderstorm environments. In contrast, the present study merges cloud-to-ground lightning flash data...

Tornadoes can cause catastrophic destruction. Here total kinetic energy (TKE) as a metric of destruction is computed from the fraction of the tornado path experiencing various damage levels and a characteristic wind speed for each level. The fraction of the path is obtained from a model developed for the Nuclear Regulatory Commission that combines theory with empirical data. TKE is validated as...
