Abstract

Frequency splitting coefficients from Global Oscillation Network Group (GONG) and Michelson Doppler Imager (MDI) data obtained during the period 1995-2000 are used to study temporal variations in the solar rotation rate. The torsional oscillation pattern in the Sun is known to penetrate to depths greater than the subsurface shear layer seen in rotation inversions. We study temporal and latitudinal variations in the properties of this shear layer. We also investigate the reported periodic variations of the rotation rate in the tachocline region in an attempt to test the results independently.
