On the Tilts Caused by Equilibrium Fluctuations of Atmospheric Pressure: Effect of Topography

Аннотация

Abstract—The influence of the relief on baric tilts is studied. Main attention is focused on two-dimensional problem. It is assumed that variations of baric field are equilibrium (horizontal component of pressure gradient is absent) and the relief is finite. The latter means that the area between the topographic profile and the abscissa axis is finite. It is shown that this area is the only geometric parameter that determines vertical displacements and tilts in the far zone. The asymptotics for the variations in vertical displacements and tilts are written out. The generalization to the three-dimensional case is presented.
