Abstract

Abstract: Based on the homogenized observed daily air temperatures from 24 meteorological stations and the NCEP/NCAR reanalysis (R1) air temperature monthly data from 1979 to 2010, the urbanization effect on air temperature changes in the Pearl River Delta region was analyzed by using the observation minus reanalysis (OMR) method. Results indicate that urbanization has significant contribution to the warming in the Pearl River Delta region, especially in winter. The annual mean/maximum/minimum temperature in the Pearl River Delta region increased at a rate of about 0.22℃/10a, 0.19℃/10a, 0.23℃/10a in 1979-2010, accounting for 55.7%, 41.7%, 57.2% of the total warming, respectively. Moreover, the urbanization effect is more obvious on minimum temperature than on maximum temperature.

Key words: Pearl River Delta, urbanization, observation minus reanalysis method, temperature change
