Includes bibliographical references (page 6). "The lengths of wet and dry periods, the relationship of precipitation with distance, and the variation of precipitation through the years of record, are matters of great interest in agricultural areas such as the Canadian Prairies. Most of the precipitation on the prairies falls in the six months, April to September, inclusive. Within the three provinces, the proportion falls to 60 per cent or lower in the Rocky Mountain area and in the upper Peace River district. The minimum value, and the only one below 50 per cent is 42 at Lake Louise. For the remainder of the area, the summer precipitation is generally 65 to 75 per cent of the annual. At a few stations, such as Hardisty, Red Deer and Three Hills, Alberta; Chaplin, Kindersley and Outlook, Saskatchewan; and Russell, Manitoba, the summer precipitation is about 75 per cent. Summer precipitation, being the most plentiful, the most variable, and the most valuable, is the subject of much of this study"--Abstract. gccst Meteorology gccst Precipitation Canada.
