There will be some nonurban pixels experiencing average annual temperature
decrease due to future urban expansion, while the annual average temperature of
most nonurban areas will be steady. The significant annual average temperature
decrease will mainly happen in the south of the Northeast megalopolis with mixed
forest (Fig.
7.25
). Statistics shows that this annual average temperature decrease
will range from 0.40 to 1.20 C. Consequently, the cooling effect in this area will
