Abstract

The annual cycle in extreme values of significant wave height is examined by transforming the timing of the storm peaks in a circular variable, with the aim of taking advantage of the many tests devised to explore uniformity on the circle. The use of four different but complementary uniformity tests makes possible a robust assessment of the annual cycle statistical significance. Seasonality of storms in a long time series of significant wave heights, measured in a coastal zone, is examined. The presence of a seasonal pattern is statistically beyond doubt. Keywords: wave storms, seasonality, circular statistics, circular uniformity.
