抄録

The local wind generated by the heterogeneity of the surface condition is investigated. The heterogeneity of the surface causes to the difference of sensible heat flux into the atmosphere. If the horizontal scale of the each surface is large enough, the thermal boundary layer depth is no more homogeneous. Then the local wind is induced dueto the pressure gradient force driven through the hydrostatic relation. The local wind in the Kanto plain in summer sometimes has large scale, because three different type of the thermal lows are combined. The relation of the accumulation of cold air and local wind in winter night is also investigated in the Kanto plain.
