Comparing
the pattern of CC variation in Figures 7 and 8 in daytime
model 11/03/2003 and 04/17/2006, when approaching coast
(the blue sample points area), the daytime model 11/03/2003
tends to show a more obvious negative correlation by a lower
negative CC value with wider covering than the model
04/17/2006. This may be due to the relatively higher wind
speed (5.67 m/s) at image time 11/03/2003 than at image
time 04/17/2006 (2.81m/s) which favored the cooling effect
of coast. Moreover with the wind direction change from
blowing from coast to land (at image time of 11/03/2003) to
blowing from land to coast (at image time of 04/17/2006) in
yellow circle area, the CC values appeared from negative to
positive indicating that the component contribution (CC) of
proximity with coast to local surface temperature variation
from temperature decrease to increase (referred as from
cooling effect to warming effect) within this area. This may
be due to the fact that when the wind blows from land to
coast, the coast in low surface temperature during daytime
may have no obvious cooling effect on local surface, even
slightly contributes to the heightening of the local surface
temperature with low positive CC values.
