Abstract
Discussed in this paper is finite amplitude ultralong wave under the influence of heat sources.The conditions are first investigated for the existence of periodic and solitary ultralong waves of finite amplitude in the Burger model with the aid of Hamilton function and variation of total energy and then the wave analytical expression is formulated by means of the functional approximation and the Hamilton function as the motion invariant in nature.Results show that the finite amplitude ultralong wave influenced by heat sources is unlikely to generate a solitary wave solution and imposes no constraints on horizontal divergence as opposed to the case with the effect of heat sources available.
