摘要

It is well established that substitution of natural land sufaces by urban elements induces changes of the local climate. Alteration of the land surfaces by urbanization characterizes distinct urban climates. Such features as the heat island, precipitation enhancement and air pollution are well documented (Oke, 1979; Landsberg, 1981). A further step in the study of urban climates is the knowledge of how the net solar energy falling on the urban fabric is partitioned. The energy balance of a city can be expressed as Q~*Q_F=Q_H+Q_E+ ΔQ_S+Q_A (Wm~(-2)) Where Q~* is the net all-wave radiation, Q_F is the anthropogenic heat flux, Q_H is the sensible heat flux, Q_E is the latent heat flux, ΔQ_S is the net storage heat flux and ΔQ_A is the net horizontal advection. Most studies on energy partitioning in urban areas have been undertaken in suburban areas in Northamerica. In this paper the energy balance of a coastal city on the Mediterranean sea is presented.
