Atmospheric processes, from microscale turbulence to severe storms on synoptic scale, have an impact on the continuous ground motion of the earth. Seismological recordings, such as the ground motion velocity, are affected by the ambient seismicity within a broad frequency band. To understand the influence of wind on seismological records, not only the genesis, the intensity and the spatial and temporal extent of meteorological systems must be considered.
This thesis investigates the ground motion in relation to atmospheric motion processes. The observation parameter, recorded by seismometers, thereby is the power spectral density of ground motion velocity. By establishing a collocated, seismological and meteorological set of recordings, the scaling of the power spectral density of ground motion velocity with the parameters as the the horizontal wind speed and wind direction is investigated.
