According to the observation data, the temperature in the city is much higher than that in the suburbs, which is the so-called "urban heat island effect". For example, the annual average temperature in Shanghai and new york is higher than that in suburbs 1. 1℃, Berlin 1.0℃, Philadelphia 0.8℃, Moscow, Paris and Los Angeles 0.7℃ and Washington 0.6℃. The following reasons can not correctly explain the "urban heat island effect" are:
