posted on 2015-06-05, 14:16 authored by Peter Argyle, Simon WatsonIncorporating atmospheric stability into wind resource assessment modelling is becoming more common. This study investigates some of the challenges associated with calculating stability in the offshore environment. Data are analysed from meteorological masts FINO1 and FINO3 in the German North Sea using measurements at three different heights and results show significant differences in stability assessment depending on which combination of heights are used. All methods show the North Sea to be very unstable for the majority of the time, although by ignoring wind and thermal data from below 50m, the atmosphere appears more stable, indicating the presence of a marine internal boundary layer. Even 80km out to sea, it is suggested FINO3 still feels the effects of land, and it is clear the height of the atmospheric surface layer effects wind speed measurements under certain conditions.
