"This investigation was undertaken to illustrate the importance of "Blocking" circulations over the North Atlantic as related to the terminal weather at Gander Airport during the month of May, (the month containing the highest percentage of poor weather during the year). Periods of prolonged poor weather (ceilings below 300' and/or 3/4 mile visibility) are examined for the months of May from 1950-1960 inclusive. Correlation between the large scale blocking-type circulations over the Atlantic and the poor weather periods at Gander are illustrated and discussed. The life cycle of the most typical Blocking sequence resulting in a prolonged poor weather period at Gander is pictured in chart form and its significant characteristics examined. The characteristic properties of prolonged poor weather periods in May are investigated. Some useful statistical parameters are derived to aid in the preparation of forecasts at Gander involving extensive low ceilings and visibilities in May"--Abstract. Gander International Airport.
