The results for temperature are similar to the results for the precipitation during summer. Figure
3-11 and Figure 3-12 also show that the three regions of the island of Newfoundland are very
similar to each other with increasing temperatures over time. Labrador has lower temperatures
than Newfoundland; however, it has a much more prominent increase in temperature over time,
especially during winter. This increase in temperature over time in all regions would suggest
that winter precipitation has a greater probability of being liquid in phase as the century
advances with this winter precipitation phase shift being more likely in the three regions of
Newfoundland as compared to Labrador. Furthermore, given that the average annual
temperature by the end of the 21st century nears the freezing point, there should be an
expectation of an increased occurrence of mixed phase precipitation and freezing rain events.
The values listed in Table 3-8 and Table 3-9 confirm the results in Figure 3-7 through Figure
3-12. That is, the regions of Newfoundland (WRMD East, Central, and West regions) are quite
similar to each other, with little or no change in precipitation during summer except in 2080 and
with increasing precipitation in the future in winter. The three regions of Newfoundland also see
similar results with regards to temperature, i.e., most of the change occurring during the winter
and accelerating through the century. Labrador sees a much greater increase in precipitation
during both summer and winter into the future. Labrador is projected to see a greater increase
in temperature during the winter but less in the summer compared to Newfoundland.
