Cauchy-Matern Model of Sea Surface Wind Speed at the Lake Worth, Florida

Cauchy-Matern Model of Sea Surface Wind Speed at the Lake Worth, Florida

We study the Cauchy-Matern (CM) process with long-range dependence (LRD). The closed form of its power spectrum density (PSD) function is given. We apply it to model the autocovariance function (ACF) and the PSD of the sea surface wind speed (wind speed for short) observed in the Lake Worth, Florida...

The present results exhibit that the CM process may yet be a novel model to fit the wind speed there.http://dx.doi.org/10.1155/2012/843676
