Climatology of Temperature and Precipitation
What do these maps represent?
By clicking on the links under "Average" you can see a map of mean observed value of temperature (in degrees Celsius) or precipitation accumulation(in millimetre or mm) for the corresponding season. The Canadian surface stations data used cover the 1981-2010 period for both the temperature and the precipitation.
The links under "Threshold" present maps of the value used as a threshold to classify the observed anomaly in one of the three categories (above, near or below normal). The climatology and threshold values for more than 100 locations in Canada are also shown at the links under "Table". The 1981-2010 climatology is now the reference climatology. Before 1 December 2011 a 1971-2000 climatology was used.
