Haboobs are dust storms produced by the spreading of evaporatively cooled air from thunderstorms over dusty surfaces and are a major dust uplift process in the Sahara. In this study observations, reanalysis, and a high-resolution simulation using the Weather Research and Forecasting model are used to analyze the multiscale dynamics which produced a long-lived (over 2 days) Saharan mesoscale con...

The local strong sandstorms (LSS), similar to haboobs in Sahara and the North America, often occur suddenly, tens of minutes during late afternoon, before dusk deserts China, causing a significant impact on atmospheric environment. Sudan haboob or American appears wet season, followed by thunderstorm events. In contrast, LSS China most frequently relatively dry season. lack observational data w...

Motivated by recent experimental and numerical results, a simple unifying picture of intermittency in turbulent shear flows is suggested. Integral structure functions (ISF), taking into account explicitly the shear intensity, are introduced on phenomenological grounds. ISF can exhibit a universal scaling behavior, independent of the shear intensity. This picture is in satisfactory agreement wit...

The simulation of nonlinear ultrasound propagation through tissue realistic media has a wide range of practical applications. However, this is a computationally difficult problem due to the large size of the computational domain compared to the acoustic wavelength. Here, the k-space pseudospectral method is used to reduce the number of grid points required per wavelength for accurate simulation...

introduction the dynamic state index (dsi) is being introduced on the basis of a newly developed theory termed the energy-vorticity theory (evt). as a weather index, the dsi can describe the temporal sequence and intensity of areas of high and low pressure; but as a climate index, it can also diagnose climate change based on the variation in solar radiation or the influences of friction. in phy...

hypothermia generates potentially severe complications in operating or recovery room. forced air warmer is effective to maintain body temperature. extremely low frequency electromagnetic field (elf-emf) is harmful to human body and mainly produced by electronic equipment including convective air warming system. we investigated elf-emf from convective air warming device on various temperature se...
