shown in Figure 3-6 which were selected to correspond to the WRMD regions. Third, and
finally, the data was averaged over the four areas and over time and compared to the 1961-
1990 baseline average. The results are presented and discussed below.
It is apparent from Figure 3-7 and Figure 3-8 that there are significant differences in the future
between the seasons over the entire province for both temperature and precipitation.
Specifically the regions of Newfoundland will have mixed results including some areas having
decreased summer precipitation and Labrador will see a varied increase during the summer
whereas during the winter, all areas see increased precipitation over time. In general the winter
season receives the greatest increase in precipitation over time, especially beyond 2050 for all
regions with the greatest increases over Labrador. Given an increase in regional temperature
due to climate change this is to be somewhat expected as the atmosphere could transport more
water vapour. The change in temperature is also different between the seasons. The
temperature over the whole province generally increases over time but this is most noticeable
over Labrador and the Labrador Sea. As with precipitation, temperature increases are greatest
in the winter months and trends accelerate beyond 2050. Although not examined in this
document, for the island of Newfoundland, the biggest changes may occur in the transitional
seasons when the island gets many of its biggest storms.
Figure 3-7 shows similar results for the precipitation changes during summer and winter. The
three regions of Newfoundland are very similar with steadily increasing rainfall over time, and
Labrador, which has a much lower average precipitation but whose precipitation increased
much faster over time.
Figure 3-9 and Figure 3-10 show similar results for the precipitation during summer (Figure 3-9)
and winter (Figure 3-10). The three regions of Newfoundland are very similar with steadily
increasing rainfall over time and Labrador which has a much lower average precipitation but
whose precipitation increased much faster over time.
