摘要: Previous measurements of the urban energy balance primarily have been conducted in summertime. This paper reports first extended set winter-spring-time for a city. The study was suburb Vancouver, British Columbia, from January to June 1987. It included hourly net all-wave radiation, sensible heat flux and Bowen ratio. anthropogenic storage fluxes were modelled. A dynamic source area model employed ensure modelled parameters consistent spatially with measured turbulent fluxes. winter-spring balances observed this are different those reported summertime conditions at same site. entire period not symmetrical about solar noon. Hence earlier interpretations possibly should be modified. Apart feature spring season similar terms relative importance individual wintertime appears that summer. most noticeable is increased latent flux, which on average largest output balance. secondary, more expected feature, as an input winter.
