Book excerpt: Analysis of ten years (1935 to 1944) of Greenwich spot data shows a consistent, and (statistically) very significant correlation of spot group proper motions, in the proper sense. These results provide strong support for the existence of large-scale waves which are some modest fraction of the solar circumference, but larger than the sunspot groups. Moreover, these waves transport angular momentum (up the gradient of angular velocity) toward the equatorial regions from higher latitudes across at least the entire sunspot zone. It is not known, however, whether these eddies are the primary (or only) source of momentum to maintain the 'equatorial acceleration' of the sun. However, if this source were shut off, and all other processes continued unabated, this layer of the sun between latitudes = 20 degrees would reach solid rotation in about 5 1/2 rotations. Because this eddy transport of momentum is counter to the gradient of angular velocity, there is an implied transformation of the kinetic energy of the eddies into the kinetic energy of the mean east-west flow. Of possibly even more interest, however, might be the possibility of transfers of kinetic energy between eddies of all different scale sizes extending down the entire spectrum to include sunspot groups and the spots themselves. Moreover, some eddy size(s) in this layer is likely to be primarily responsible for a conversion of potential to kinetic energy.

Available in PDF, EPUB and Kindle. Book excerpt: Phenomena of the terrestrial atmosphere are bound up with solar activity in such a multiplicity of ways, that no occasion for surprise arises from the increasing interest of meteorologists in the physical processes and actions taking place in the sun. As a matter of fact this situation has existed for a great many years. Yet, were it not for the fairly recent growth of an added dimension to the joint study of terrestrial and solar problems, specific justification for the present volume would be incomplete. In brief, dynamical actions have been found to be present, common to the atmospheres of both the earth and sun. These actions involve kinetic and other forms of energy and their transformations. Likewise the turbulent transport of momentum appears to have like qualities in the two systems. The recognition of these similarities has also had the effect of enabling us to see more clearly the nature of some solar processes for which there are no close equivalents in the earth's atmosphere. Thus the general shape of the dynamo action in the photosphere has come to be visualized to better advantage. As a consequence it has become possible to create new mathematical models for this hydromagnetic system. The initial clue for these developments has been the realization from data studies that the maintenance of the sun's equatorial acceleration is effected through a mechanism analogous to that which is responsible for the maintenance of the differential rotation of the terrestrial atmosphere. Nor are there reasons lacking to support the view that this mechanism -- essentially a negative viscous action -- is in fact of quite common occurrence in many natural fluid systems characterized by the presence of a mean differential rotation. In Part II of this collection a few papers dealing with the manifestation of this phenomenon in spiral galaxies and in the solar nebula are included for interest's sake. A brief article by E. N. Lorenz on the earth's atmosphere is reproduced in the Appendix for the same reason. On the one hand the present volume may serve the purpose of a supplement to the book "Physics of Negative Viscosity Phenomena", by V. Starr, McGraw-Hill, 1968; on the other, it may also serve as an amplification and rounding out of the material contained in the collection of reprints entitled "Observational Studies of the Atmospheric General Circulation", compiled by V. Starr and B. Saltzman, M. I. T. Planetary Circulations Project, 1966. Mention should here be made also of the collection of pertinent theoretical articles entitled "Selected Papers on the Theory of Thermal Convection with Special Applications to the Earth's Planetary Atmosphere", by B. Saltzman, Dover Publications, 1962.
