%X The concept of optimal sensitivity perturbation is developed basing on analyses to adjoint sensitivity The persistent anomalous features of the East Asian summer circulation in 1991, including the Ural blocking, the East Asian dipole blocking and the variation of the subtropical high pressure, which have caused severe floods in the Yangtqe River and Huaihe River valleys are analyzed with the adjoint model Every initial perturbations with the strongest influence upon the above each anomaly, respectively, are obtained The results revealed the most important factors in these systems form a new aspect and showed the efficiency and great potential of further applications of the method of the adjoint sensitivity analysis in the diagnoses of the physical processes of atmospheric general circulation
