The spatial and temporal characteristics of wavy and modulated wavy Taylor vortex flow (WVF and MWVF) between two concentric spheres with the inner sphere rotating (the spherical Couette system) are investigated using the aluminum-flake method. The WVF and MWVF having no spiral Taylor-Gortler vortices are realized by a slightly greater acceleration rate of the Reynolds number than that of quasi-static increasing. Four mirrors are used in the case of the front lighting of the whole region to determine the time evolution of the entire wave pattern around the sphere. Observing the meridional cross-section of the spherical annulus by slit illumination, and taking a photograph of it are also employed to obtain more quantitative data than those in the case of front lighting. The results of the spherical Coutte system are compared with those of the circular Couette system.
