We have used available helioseismic data for the solar cycle 23 to undertake a detailed study of temporal variations in solar rotation. We concentrate mainly on variation of the radial and latitudinal gradients of rotation. We find that the temporal variations of the rotation-rate gradients is about 20% or more than their average value, i.e., much larger than the relative variation in the rotation rate itself. These variations may play an important role in solar dynamo models.
