Abstract(unpublished)
The map shows the mean daily temperatures based on the 30-year period 1941-1970 for the warmest month in Canada. Although, the most direct and the most intense incoming solar radiation occurs in June, there is a lag in the warming of the Earths surface. As a result the warmest month in Canada is normally July. The lowest mean July temperatures are below 5 degrees Celsius and are located in the Arctic Islands. The highest mean July daily temperatures are above 20 degrees Celsius and are located in southern Ontario, southern Quebec, south of Winnipeg, Manitoba, the Medicine Hat area of Alberta and in some valleys in the interior of British Columbia. Generally, the mean increases from north to south, from 2.5 to 22.5 degrees Celsius. In British Columbia, the warmer temperatures are in river basins of the Cordillera. In fact, all valleys of the Cordillera are warmer than the surrounding slopes. In winter, however, atmospheric inversions may result in valleys being warmer or colder than higher terrain. T
