This paper addresses the physics and numerical simulation of the adiabatic generation of infrasound by tornadoes. Classical analytical results regarding the production of infrasound by vortex Rossby waves and by corotating “suction vortices” are reviewed. Conditions are derived for which critical layers damp vortex Rossby waves that would otherwise grow and continually produce acoustic radiatio...

Tornado is a new advanced kernel for modelling and virtual experimentation (i.e., any evaluation of a model) in the water quality domain. Although primarily intended for use within this particular domain, the kernel is generic in nature and has a plethora of generally applicable features. Tornado often deals with elaborate models and many of its virtual experiment types are computationally inte...

Why do we want computer to become even faster? Computers are very fast already. Yes, they are getting faster year after year, but, honestly, other than making videos more realistic and faster to download, from the purely scientific viewpoint, there is no big reason to replace a 5-year old computer with the new one: already on a 5-year old computer, we can do all the editing and all simple compu...

This study investigated the role of duration and tornado-induced static pressure on peak pressures on a low-rise building. A tornado simulator was used to generate both translating and stationary vortices to measure pressure time series on a building model. Time-resolved velocity measurements were also made on the vortex to aid in the analysis. Past studies have suggested that peak pressures on...
