Paper Abstract

Based on MODIS data of Shanghai City from 2003 to 2005, land surface temperature (LST) was retrieved and used indirectly to get the quarterly intensity and higher temperature area of urban heat island. Results show that (1) the mean highest LST is 13.9°C in winter and 32.5°C, 45.7°C and 29.0°C in spring, summer, and autumn, respectively; (2) the relatively higher LST area distribution has obvious seasonal variation, which moves southeast in winter, northwest in spring and summer, and draws back southeast again in autumn; (3) weak urban cold island exists in urban areas during winter mornings; urban heat island exists in spring, summer and autumn; the summer's heat island is the most notable; and (4) LST of urban cold island centre in winter morning is 2.6°C lower than that of countryside and the mean urban heat island intensity is 5.7°C, 10.4°C and 4.2°C in spring, summer and autumn, respectively.
