The relationship between barometric and strain data related to seasonal characteristics within a year was studied on the basis of parallel records from a quartz tube extensometer and a microbarograph at the Geodynamical Observatory in Sopronbánfalva, Hungary. Both strain and barometric data series were combined into groups according to the three ‘Lloyd’ seasons and they were subjected to spectrum, tidal, regression and coherence analysis. All of the analysis methods establish long periods, with seasonally varying relations between atmospheric pressure and linear deformation measurements in the tidal frequency band. We found that the separate seasonal barometric correction of the strain data did not bring a notable improvement in the diurnal band, while in the semidiurnal band the improvement was about 10% better than correcting the whole year's data in a single step.
