Abstract : Results obtained by the investigation of short-term reactions of the general circulation to sudden solar disturbance are summarized as follows: (a) The superposed epoch means of the daily standardized departure patterns of sea-level pressure do not appear to be related to any significant degree to the key day of solar disturbance. (b) There is significant evidence of some suppression of the variability of the daily patterns of sea-level pressure departures on days following the key day of solar disturbance, most notably on days 0 to +4 during the winter half year and on days +6 to +10 during the summer half year. (c) There is significant evidence of some increase of the variability of the daily patterns of sea-level pressure departures at approximately day +14 following the key day of solar disturbance. (d) Correlation evidence supports only to a limited degree results (b) and (c), primarily that of some suppression of the variability of the daily pressure departure patterns on days 0 to +4 during the winter half year. (e) The resemblance of these results to those derived in the study of solar-climatic relationships lies in the fact that more significance attaches to variance relationships than to mean pattern relationships. Significance levels are generally lower for the short-term than for the climatic relationships.
