Drought is a deficiency in precipitation over an extended period, usually a season or more, resulting in a water shortage that has adverse impacts on vegetation, animals and/or people. The Climate Moisture Index (CMI) was calculated as the difference between annual precipitation and potential evapotranspiration (PET) – the potential loss of water vapour from a landscape covered by vegetation. Positive CMI values indicate wet or moist conditions and show that precipitation is sufficient to sustain a closed-canopy forest. Negative CMI values indicate dry conditions that, at best, can support discontinuous parkland-type forests.

The plate contains four maps of 60 minute rainfalls (in millimetres) for a 2 year return period, a 5 year return period, a 10 year return period and a 25 year return period. Each map has a detailed inset of the Vancouver area. These four maps were not analyzed for the mountainous parts of Canada in British Columbia and the Yukon because of the limited number of stations, the non-representative nature of the valley stations and the variability of precipitation owing to the orographic effects. From the incomplete data, it is impossible to draw accurate isolines of short duration rainfall amounts on maps of national scale.

Water demand is usually measured by evapotranspiration: the amount of water that would be evaporated and transpired by plants. Potential Evapotranspiration (PET) is the demand or maximum amount of evaporation that would occur if sufficient water were available (from precipitation and soil moisture). Priestly-Taylor equations were used to estimate daily PET.

These values are calculated across Canada using historical climate station data from ECCC with the Versatile Soil Moisture Budget model (Baier and Robertson, 1996 and Baier et al., 2000).
