The Level Crossing Method applied to mean wind speeds from “mixed” climates

This process also uses the idea that rare crossings of high levels are a Poisson process. The correlation of the parent introduces systematic errors from this assumption, but these are small and have the advantage of decreasing as the wind speed level increases. Given a means of separating “mixed” wind regimes by the newly available OEN analysis, an up-dated version of the Level Crossing Method appears to be a possible new penultimate method for extremes.
