change occurs in December and January, the change scale being 0.025-0.03C. The
simulated result about monthly average temperature is further confirmed that the
grassland degradation would lead to higher temperature.
The grassland occupies largely in Mongolia and decrease significantly from 1.3
million hectares to 0.9 million hectares from 1990s onward. Overall, the simulated
results of the monthly average precipitation during 2010-2020 and 2040-2050 are
quite similar. The precipitation in summer is significantly higher than in winter,
and the range of monthly average precipitation variation is from -3 to 5 mm
(Fig.
7.22
). It can be seen clearly that precipitation changes obviously in June-
August, the monthly average precipitation in the three months is 3-5 mm higher
than that in the baseline year, while in the other months the monthly average
precipitation is lower than that in the baseline.
