Combing the MMOCAA "(The modified method of characteristics with adjusted advection, Jim Douglas. Jr., Numer. Math. (1999), Vol. 83: 353-369)" difference method with ENO, the ENO-MMOCAA difference method is proposed for covection-diffusion equation in the paper. The new method is free from oscillation near the steep front, with which the problem is solved by the MMOCAA difference method based on high-order Lagrange interplation.
