1978 First Edition published by NASA in vanilla wraps with a cover illustration of the Sun with a prominense and the Earth. The book is in Very Good+ condition. The covers look great. The binding is tight. The former owner's name and date are neatly printed on the title page. The interior pages are clean and unmarked. USPS electronic tracking number issued free of charge. From the Publisher: This work reviews both long and short-term meteorological variations related to solar activity and the few physical linking mechanisms that have been suggested to explain the relationships. Several new mechanisms are postulated with varying degrees of completeness to supplement those already reported in the literature. Physical background material is provided where appropriate to assist the reader in grasping the concepts presented.The book also examines some experimental concepts useful for investigating physical links between solar variability and meteorological responses. The rationale for this objective is that, despite the vast literature supporting a probable connection between the two phenomena, there is considerable disbelief for such a connection. This disbelief seems to be based principally on the fact that no plausible physical mechanisms have been identified to explain how the relatively minor fluctuations in solar energy output can influence or drive the vastly more energetic meteorological processes. If linking mechanisms can be identified, the subject of Sun-weather relationships will be on much firmer ground, and improved predictions of climatic trends and weather changes may in fact become possible.From these few introductory remarks it can be appreciated that the subject we address is truly multidisciplinary. It will be seen in subsequent pages that even the present modest effort touches on solar physics, magnetospheric physics, atmospheric physics and chemistry, atmospheric electricity, cosmic rays, geomagnetism, and meteorology. To gain new insights into Sun-weather relationships we believe it is necessary to combine the extant knowledge of all these disciplines and interpret that knowledge in new ways. We do not claim to do that here, but we do attempt to bring together, and in some cases simply point out, the essential ingredients required.In that spirit, the characteristics of solar variables and solar energy sources suggested to be related to weather and climate fluctuations are discussed in chapter 2. Included are galactic cosmic rays and geomagnetic activity, since variations in the intensity of these phenomena are related to solar activity, and both have been observed to be correlated with weather changes.Long-term climatic trends and their association with solar activity are examined in chapter 3. In some cases it has been noted that correlations between meteorological phenomena and the sunspot cycle may persist for several cycles and then break down or even reverse sign. These peculiarities may be indicative of a fortuitous correlation between unrelated variables, or they may point toward an as yet undiscovered key to an undefined link between two seemingly independent variables that are in fact related. Because of these two important possibilities, a separate section (3.3) is devoted to such breakdowns and reversals.Short-term correlations between meteorological parameters and transient solar phenomena, such as solar flares and solar magnetic sector boundaries, are treated in chapter 4. Correlations between weather changes and magnetic activity as an indicator of solar variability are included in this chapter.In chapter 5, the possibility that observed correlations between magnetic activity and weather phenomena are unrelated to solar activity is examined briefly. The heart of the problem, that is, the physical processes and mechanisms that produce the observed correlations, is addressed in chapter 6. Here the discussion must be speculatory and in some cases naive, because no hypotheses have been proven that e.
