A Climatic Model of Urban Energy Budgets

Abstract

A deductive model of the energy budgets of urban landscapes, based on the exchanges of energy, mass, and momentum, is introduced. The absorption of shortwave and longwave radiation and their dissipation via the channels of reradiation, convection, conduction, and evaporation are generated by the model in order to simulate the interplay of the many energy cascades among the myriad of city surfaces. A city can be geographically analyzed by determining its energy budget and resultant surface temperatures on a block‐by‐block basis. In spite of some simplifying assumptions, the predictions of surface temperatures of this initial model compare favorably with observations. 1974 The Ohio State University
