THE EFFECT OF URBAN STRUCTURES ON SEA BREEZE PENETRATION OVER THE KANTO PLAIN - ANALYSIS BASED ON MEAN KINETIC ENERGY MODEL -

The sea breeze over the Kanto Plain in Japan is simulated using a mesoscale meteorological model incorporating with an urban canopy model. The inland penetration of sea breezes is accurately reproduced. Additionally, a mean kinetic energy balance within a domain (Control Volume; CV) moving along the sea breeze is evaluated. From the results, it is clarified that the sea breeze is interrupted by the resistance and turbulence caused by buildings at the center of Tokyo. The interruption effect is increased in accordance with the height of urban structures. On the other hand, adverse pressure gradients interrupt in the internal region.
