Typhoon Marie is noted for her unusual behaviour of redevelopment over the Japan Sea. An analysis is attempted under a supposition that such a situation can be explained by superposing an extratropical cyclone on the Main Typhoon. The results show that the development of the superposed extratropical cyclone accounts fully for the apparent redevelopment of such a typhoon, the Main Typhoon being considered to be at the decaying stage during that period. To say conclusively, the above mentioned supposition is confirmed synoptically in the present paper, leading to an important suggestion on the mechanism of redevelopment of the typhoon in the middle latitudes.
