Further evidence of a solar corpuscular influence on large-scale circulation at 300 Mb

Statistical evidence from three successive winter half-years strongly indicates that, when the earth is bombarded by unusually intense solar corpuscular emission, certain troughs in the 300-mb circulation are subsequently amplified. The troughs so affected enter or are formed in the Gulf of Alaska–Aleutian Islands area on the second, third, or fourth day after the start of the corpuscular increases. The trough amplifications maximize a variable number of days later, which may explain why the result was not apparent to earlier workers. The result has been found independently, at about the same level of significance, in the data each of the three winters treated separately. For the data of three half-years grouped together the probability of such a strong chance association is less than 10−6.
