Brown, B.H. (2008) Short-term changes in global cloud cover and in cosmic radiation. Journal of Atmopsheric and Solar-Terrestrial Physics, 70 (7). pp. 1122-1131. ISSN 1364-6826
Abstract
Galactic cosmic rays (GCR) have been suggested as a possible contributory mechanism to cloud formation. If these are significant then, in addition to the similarity between long-term (years) changes in GCR and cloud cover, there should also be a similarity over shorter (days) time scales. This paper reports an analysis of changes in global cloud cover and GCR recorded at 3 hourly intervals over 22 years. There is a significant correlation between short-term changes in low cloud cover over northern and southern hemispheres, consistent with about 3% of the variation arising from common factors. However, GCR is not a major factor responsible for cloud cover changes. There is an association between short-term changes in low cloud cover and galactic cosmic radiation over a period of several days. This could arise if approximately 3% of the variations in cloud cover resulted from GCR.
