Analysis of sensible heat, latent heat and mean kinetic energy balance of moving control volume along sea breeze based on mesoscale climate simulation

Abstract

The authors have proposed new models to calculate heat balance and mean kinetic energy balance of urban space. In these models, an arbitrary domain fixed a certain region is regarded as the Control Volume. By using these models, the heat and mean kinetic energy structures of each region of the Tokyo metropolitan area have been analyzed under a meteorological condition dominating sea breeze on a typical sunny day in summer. However, to clarify the interaction between sea breeze and urban climate, it is necessary to focus on the sea breeze itself. Therefore, the authors propose a new concept "moving Control Volume" along the sea breeze, and heat and mean kinetic energy balances of the moving Control Volume are calculated. From numerical simulations, to raise the height of buildings changes the temperature, absolute humidity, and penetrating speed of sea breeze. In this paper, the reasons are explained quantitatively with respect to the heat balance and mean kinetic energy of the sea breeze.
