Diurnal Surface Flux Variability Over Western Boundary Currents

WebDiurnal (daily) variation of wind is caused by strong surface heating during the day, which causes turbulence in the lower levels. The result of this turbulence is that the direction and speed of the wind at the higher … WebWinds play an essential role in the climate system. In this study, we analyze the global pattern of the diurnal cycle of surface (10 m) winds from the ERA5 reanalysis data. We nd that over the land and especially over sand dune regions, the maximal wind speed and wind drift potential (DP) occur during the hours around midday. WebHourly wind measurements collected from 53 moored buoys in the Tropical Atmosphere Ocean array (9°N-8°S, 165°E-180°W) from 1993 through 2002 were used to document seasonal changes of the diurnal and semidiurnal harmonics of surface wind variability.
