This report illustrates the typical weather in Cochrane year round, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Cochrane.
For each station, the records are corrected for the elevation difference between that station and Cochrane according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
The estimated value at Cochrane is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Cochrane and a given station.
The stations contributing to this reconstruction are: Calgary / Springbank Airport (78%, 12 kilometers, southeast); Bow Valley (11%, 43 kilometers, west); Sundre (6%, 67 kilometers, north); and Olds AGDM (5%, 69 kilometers, northeast).
