nowadays, soil reinforcement using polymer elements have been investigated by a number of researchers in order to increase the load capacity of soils. reinforcing soils using fibers is a method of soil improvement, which offers a homogenous mixture in combination with soils, regarding their tensile strength. this combination maintains pressure loading capacity and properties in mutual resistant...

The long duration of the 2010 Eyjajallajökull eruption provided a unique opportunity to measure a widely dispersed volcanic ash cloud. Layers of volcanic ash were observed by the European Aerosol Research Lidar Network with a mean depth of 1.2 km and standard deviation of 0.9 km. In this paper we evaluate the ability of the Met Office’s Numerical Atmospheric-dispersion Modelling Environment (NA...

The existence, scale, and growth rates of subsynoptic-scale warm-core circulations are investigated with a simple parameterization for latent heat release in a nonconvective basic state using a linear two-layer shallow-water model. For a range of baroclinic flows from moderate to high Richardson number, conditionally stable lapse rates approaching saturated adiabats consistently yield the most ...

Awan cumulonimbus merupakan jenis awan berbahaya yang dapat menimbulkan cuaca ekstrim seperti hujan deras, kilat dan guruh. Jenis angin mempengaruhi adanya adalah Vertical wind shear, dengan ini menentukan badai terjadi. Apakah termasuk kedalam intensitas hebat atau tidak. Karena semakin besar shear akan juga terjadi akibat cumulonimbus. Untuk mengetahui keterkaitan pada pertumbuhan maka diadak...

From the analysis of thermistor chain data recorded in a small clongatcd lake, compared with the results of numerical simulations, second vertical modes of the internal scichcs are shown to be active during more than twothirds of the whole stratifcd period, although no rcsonancc with the wind is observed. On the other hand, due to the wind pattern, transversal seiches (mainly the first vertical...

A model of vortex with embedded discontinuities in plasma flow is developed in the framework of ideal MHD in a low β plasma. Vortex structures are considered as a result of 2-D evolution of nonlinear shear Alfvén waves in the heliosphere. Physical properties of the solutions and vector fields are analyzed and the observational aspects of the model are discussed. The ratio of normal components t...

The turbulence regime in a quasi-stationary, horizontally evolving, and sheared boundary layer with bottom buoyancy forcing has been studied numerically by means of large eddy simulations (LES) in conjunction with its experimental investigation in a laboratory wind tunnel. The atmospheric prototype of the investigated boundary layer is commonly observed in the earth’s atmosphere during daytime ...
