We use an early twentieth century (1908–1958) atmospheric reanalysis, based on assimilation of surface and sea level pressure observations, to contrast atmospheric circulation during two periods of persistent drought in North America: 1932–1939 (the ‘Dust Bowl’) and 1948– 1957. Primary forcing for both droughts is believed to come from anomalous sea surface temperatures (SSTs): a warm Atlantic and a cool eastern tropical Pacific. For boreal winter (October–March) in the 1950s, a stationary wave… CONTINUE READING
