3.1 Meteorological Conditions
The overall meteorological conditions observed over the Romaine-2 reservoir were typical of a subarctic climate (Fig. 6), with cool and humid summers along with cold and dry winters. Wind speed (WS ) was generally quite high, particularly in the fall and winter when daily averages occasionally reached 15 m s–1, but showed a marked decline in summer. The reservoir was mostly colder than the air above it between May and July (the heat storage period). The vapour pressure deficit (VPD) values were high from mid-spring to mid-autumn.
