Based on mesoscale eddy dataset from February 1993 to January 2016, the distribution characteristics and evolution processes of mesoscale eddies in the Indo-Pacific Warm Pool (15º S~15º N, 60º E~170º W), and its seasonal variation and relationship with ENSO are statistically analyzed in this paper. It shows that most mesoscale eddies in the Indo-Pacific Warm Pool are short-lived and nonlinear, and propagate westward. The study also finds that the distribution characteristics of cyclonic eddies and anticyclone eddies are similar, and so do their variation trends over the eddy lifecycle. The seasonal numbers of mesoscale eddies vary insignificantly in the whole domain and are affected by ENSO in the meanwhile.
