Based on the tropical cyclone（TC）asymmetric disturbance as the superposition of thesymmetric environmental circulation,the analytical solution of travelling wave is given by usingthe barotropical nondivergent model with diabatic heating forcing and non-friction in a plane polarcoordinate.Then,the TC radial inhomogeneous structure is analyzed on radial/tangential velocityand geopotential height.It is found that the different kinds of structures are influenced by theCoriolis parameter（f）,TC intensity（Ω）,disturbance circular frequency（ω）,and TC angularwavenumber（m）.And,the diabatic heating（Q1）has significant impacts on the radial/tangentialvelocity distribution shaped like the inner-tight and outer-relaxed.
