**Abstract:**

*A procedure to construct a modified velocity field that does not have any mean flow in a convecting flow was developed. Application of the procedure showed that spiral defect chaos does not survive when the mean flow is quenched. Instead, a pattern characterized by textures of stripes with angular bends appeared. Furthermore, it was shown that the mean wave numbers of these quenched patterns approach those selected by focus-type singularities.*
