Abstract

Clear observations of small but abrupt changes in gravity during the passage of cold fronts are reported. Instrumental effects can be ruled out by special experiments. Simple models for the atmosphere show that the direction and the order of magnitude of the observed effects can be explained by changes in gravitational attraction of the sensor mass by the atmosphere or by downward acceleration of the ground due to the increasing air pressure. This is additional evidence for the high importance of meteorological causes for long-period seismic noise.
