جزیره گرمایی شهری در مسکو

Weekly course of the air temperature in Moscow is closely connected with the urban ‘heat island’ phenomenon. On the average during the last 50 years there was a gradual increase of T during week-days and sharp decrease (cooling) on weekends. This may be explained by industrial haze which is gradually accumulated from Monday to Friday and reduces effective nocturnal radiation in the city, especially during winter nights.
