Study on the Correlations between Surface Temperature and Near-Surface Air Temperature on Different Underlying Surfaces in City of Wuhan, China
Ailing Cai and Daohua Hu
Abstract—In the study of the urban heat island, the
correlation between surface temperature and air temperature
near the ground remains an interesting topic, especially under
the different underlying surfaces. This paper investigates such
correlations based on the data collected in 7 matrixes, each with
24 sets of data, in Wuhan in August 2015. Regression analysis
method is used with Ts and Ta of different times and different
underlying surfaces, and this analysis can help to explore the
mechanism of the differences. The paper comes to the following
conclusions: 1). On different underlying surfaces, Ts and Ta are
not consistent. The coefficient of determination of the degree of
fitting of hard paving and open space is better, then, arbor,
bush and meadow, in turn reducing. Water space is least. 2). On
the same time node, with the increase of solar radiation, the
difference between Ts and Ta reduces and the rate of Ts is
higher than Ta. 3. On different underlying surfaces and time
nodes, Ts changes faster than Ta and the difference of Ta and
Ts is maximized at 14 o'clock of the day, among which the
difference of hard pavement is the greatest, followed by open
space, meadow, bush, arbor and water. In the process of
urbanization, the heat island will increasingly evolve with
road-hardening and building density increasing. Therefore, we
should make effort to increase the area of underlying surfaces
of greenbelt and water in order to reduce the heat island effect
and to enhance human body comfort.
