Taylor-Couette flows developing between two rotating cylinders have various flow modes which show different flow patterns even though the length of cylinders and the Reynolds number are kept constant. In this paper, we show that the non-unique phenomena are found not only in the steady flows but also during the formation processes of final flows. Subjective observations of flow vectors or contours of flow functions are usually used to determine flow modes. We introduce a new quantitative mode-detection method that is based on the human knowledge about the vortices appearing in the flow fields. This method is utilized to estimate the information given by the nonlinear dynamics found in Taylor-Couette flows.
