Abstract

One of the energetic characteristics of the wind field, the frequency of the so-called windy days is investigated in the period 1971-2000 using datasets of seven observatories in Hungary. Windy day is defined as a day with daily maximum wind speed higher than 10 m/s. Basic statistics are determined and time-course of monthly and yearly means is analysed by fitting of trigonometric polynomials. A measuring number is defined to decide the goodness of the fitting and the suddenness of the different periods is investigated. The approach of the function fitting the course of monthly means is very good but only the yearly period is significant. The goodness of the function fitting the course of yearly means is even weaker and we can find geographical differences. The same is true for the suddenness of periods.
