This paper analyzed the behavior of sea breeze (hereafter SB) penetration to urban area in Kanto. In order to analyze SB penetration, we proposed a new method for SB-front detection using very high-resolution-geostationary satellite images, or MTSAT-2 Rapid Scan, with 1 km-spatial and 5 min.-temporal resolution. From the images, the detailed behaviors of SB were successfully visualized. For the selected SB events, the penetrations to in-land from Tokyo bay and Sagami bay were discussed using the point data of AMeDAS and Atmospheric Environmental Regional Observation System (AEROS), and also a result from the meso-scale simulation, where the important urban effects were parameterized (e.g., actual aero-thermodynamic parameters, anthropogenic heat and vapor emission). Along Tokyo-Saitama line, SB stagnation occurred in every sea breeze event. The observed higher air temperature and convergence resulted in increased vertical mixing, leading to SB stagnation.
