Popis: To estimate air moisture flux (Ms), 400 points meteorological data at the surface of the Japan Sea are analysed on the assumption of adiabatic change. The wind field at the upper-layer (900, 850, 800hPa) was obtained from thermal wind.Estimated Ms is nearly close to air moisture income (Ma) culculated by aerological data. The air moisture balance δM is high correspondance to the monthly precipitation amount. Spatial distribution of Ms over the Japan Sea is clarified and Ms is significantly affected by the sea surface temperature.
