โœฆ Synopsis

The equatorial rotation rate of the supergranulation cells has been observed to be 14.72 -4-0.07~

Velocity patterns observed at different times are cross-correlated to derive the rotation rate. The observed rate is 3% faster than recent observations of the surface rotation rate by Doppler shifts. The difference between the cell rate and surface rate is consistent with a model of the supergranular convection in which angular momentum per unit mass is conserved in the radial flow (Foukal, 1977).

We have used an atomic-beam resonance-scattering technique applied to the 7699,~ solar potassium absorption line to make an absolute spectroscopic determination of the solar equatorial rotation rate. To our knowledge this is a new method which has not previously been used for studying solar rotation

Howard and Harvey (1970) analyzed Mt. Wilson Doppler shifts to obtain a daily measure of the Sun's differential rotation. The data were fitted to give an angular velocity of the form oJ = a + b sin 2 B + c sin 4 B (B = heliographic latitude). Changes in a, b, c were found to be correlated (Howard

In the standard model of the solar convective zone, turbulent eddies transport entropy rather than temperature. We consider the turbulent mean field equations for the convective zone, including entropy transport, and show that the zone can be unstable to larger scale motion which we identify with th

Published spectroscopic measurements of solar rotation are analyzed to show that when the rotation velocity increases at high latitudes it tends to decrease at low latitudes, and conversely. The high latitude velocities typically vary over only 20 % of the range of those near the equator and the sma
