The wind erosion stochastic simulator (WESS) is a single event wind erosion model that is the core of the wind erosion submodel of the environmental policy integrated climate (EPIC) erosion model. WESS uses inputs of soil texture, erodible particle diameter, soil roughness, soil water content, crop residue, and 10 min average wind speeds to predict the erosion at several user-selected distances...

Through the wind velocity and direction monitoring system installed on Jiubao Bridge of Qiantang River, Hangzhou city, Zhejiang province, China, a full range of wind velocity and direction data was collected during typhoon HAIKUI in 2012. Based on these data, it was found that, at higher observed elevation, turbulence intensity is lower, and the variation tendency of longitudinal and lateral tu...

A wind scatterometer makes measurements of the normalized radar-backscatter coefficient of the ocean surface. To retrieve the wind, a geophysical model function (GMF), which relates to the near-surface wind, is used. The wind vector can be estimated using maximum-likelihood techniques from several measurements made at different azimuth angles. The probability density of the measured is assumed ...

Scatterometers are radars specially designed to nearsurface wind over the ocean from space. Traditional scatterometer wind estimation inverts the model function relationship between the wind and backscatter at each resolution element, yielding a set of ambiguities due to the many-to-one mapping of the model function. Field-wise wind estimation dramatically reduces the number of ambiguities by e...

The release of harmful contaminants is a potentially devastating threat to homeland security. Accurate identification of the source strength and location is essential to minimize the impact. Insufficient spatial and temporal resolution as well as inherent uncertainty in wind field data makes characterizing the source and predicting subsequent transport and dispersion extremely difficult. The so...
