In this paper, the relationship between Jelesnianski's and Rankine's combined vortex of typhoon wind field distribution is analysed, and new calculation methods for typhoon wind speed are suggested. The calculation methods of typhoon wind field distribution have improved Rankine's and Jelesnianski's model, and overcome the shortcoming that the wind speed calculated with the Jelesnianski' s model is overestimated and the shortcoming that the wind speed calculated with the Rankine's model is underestimated.Wind speed distribution curve of the second new wind model v2 is better than that of Jelesnianski's and Rankine's model, and has a reasonable trend of speed decrease from maximum wind radius to infinite distance. At the same time, the computation method of moving typhoon wind field has, to some extent, improved Myazakimasa-mori's and Jelesnianski's metods.
