Abstract : The research reviewed was directed toward the development of a method of objective forecasting of solar flare phenomena. This was done through efforts to construct mathematical models of the outer layers of the sun, to be solved by machine integration in a manner similar to the procedures used in meteorological forecasting on a hemispheric or global scale. In the solar case magnetic terms are included, and various other complicating factors are treated. One preliminary model was prepared for purposes of orientation. This much simplified model was solved largely by analytical methods. It indicated the general feasibility of the approach used, and displayed many details in agreement with observations. A second global two-layer model was designed and partially tested. It showed, when properly adjusted, an equatorial acceleration, a dynamo action which actually is probably too vigorous, and a tendency to oscillate with a period of the general order of the solar cycle. The two hemispheres showed a general opposing magnetic polarity. Further testing is now in progress. (Author)
