Abstract
Introducing a modified in t e gral diffusivity whose integral range does not contain the surface values of temperature and water vapour, the bulk aerodynamic method is surveyed by the use of the data obtained on the joint exploration, which was carried out at the Chiba seaport in 1966 by the Meteorological Research Institute, the observational section, JMA and the Meteorological College.
Comparisons of the estimation of H and E du e to the profile method with that due to the bulk method are made and the dependence of the modified integral diffusivity on the stability ratio is also sought. Finally the empirical bulk equations for the estimation of H and E without using the surface values are presented.
