The response of the troposphere at 500 mb level to solar magnetic sector crossings (SMSC) has been investigated in terms of two dynamical atmospheric indices, kinetic energy density and square of the vorticity of the main motion. Daily values of these indices at high and middle latitudes in the Northern Hemisphere for quiet and active solar conditions have been computed using the geostrophic wind approximation. No relationships were found between SMSC and these particular atmospheric indices irrespective of solar activity, latitude, season and interplanetary magnetic field (IMF) polarity. The present investigations lead to conclude that if any effect associated with SMSC is accepted, it should be associated only with the vorticity area index for low pressure trough areas in winter.
