WebJul 17, 2024 · As there is no diurnal SST and thereby no diurnal ΔQ cycle during these months as shown in Figure 3f, this cycle is determined by the atmospheric humidity, meaning that the near surface boundary layer is moister during the nighttime and drier during the daytime. Conversely, the winds are elevated at nighttime and begin … 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.
