A SIMULATION OF SEA BREEZE OVER FUKUOKA METROPOLITAN AREA

Abstract

A numerical simulation was carried out to investigate the characteristics of sea breeze intrusion on the Fukuoka Metropolitan area by using ARPS and the results were compared with the field data of sea breeze obtained in August 2, 2003. The sea breeze front runs parallel to the costal line at the beginning of the sea breeze intrusion, but as it goes into the inland, the two-dimensional front becomes wavy and breaks. The sea breeze consists of the tail of about 600 m thickness and the head 1000 m and above high. The head is accompanied with a pair of upward and downward currents that reach to about 2000 m height.
