The unusual Buenos Aires snowfall of July 2007
Abstract Buenos Aires lies near the east coast of South America at about 34°S where snow is extremely rare. The only events measured in the city had occurred before 1930. The high latitude causes of the widespread snowstorm of 9th July 2007 are discussed, making it an extraordinary case in light of...
