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

الملخص EN

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, over the 1984–2006 period.

The present results exhibit that the wind speed at the Lake Worth over 1984–2006 is of LRD.

The present results exhibit that the CM process may yet be a novel model to fit the wind speed there.
