In this paper, we introduce a distanceon the equivalence classes of spherical curves under deformations of type RI and ambient isotopies. We obtain an inequality that estimate its lower bound (Theorem 1). In Theorem 2, we show that if for a pair of spherical curvesand,andandsatisfy a certain technical condition, thenis obtained fromby a single weak RIII only. In Theorem 3, we show that ifandsatisfy other conditions, thenis ambient isotopic to a spherical curve that is obtained fromby a sequence of a particular local deformations, which realizes.
