In　this　paper,　we　analyzed　the　effect　of　SST　on　the　precipitation　of　coastal　areas　of　the　eastern　China.　The　relationship　between　the　precipitation　and　SST　of　different　seasons　based　on　CMDC＇s　monthly　precipitation　data　and　NOAA＇s　SST　data　from　1979　to　2016　was　calculated.　Analysis　on　the　links　between　precipitation　and　SST　has　shown　a　significant　correlation　in　winter　and　spring,　with　three　positive　strong　oceanic　signals　and　two　negatively　correlated　sea　areas.　Meanwhile,　the　precipitation　and　SST　of　highly　correlated　regions　have　increased　during　the　past　38　years.　Considering　the　seasonal　variation,　precipitation　presents　upward　trend　in　summer　and　winter　with　appreciable　seasonal　variations.　For　one　of　the　highly　related　areas,　such　as　the　East　China　Sea　(ECS)　and　the　north　of　Philippine　Sea　(PS),　the　SST　there　has　been　increased　in　all　four　seasons.　Spectral　analysis　also　shows　that　the　precipitation　and　the　MEI　have　the　same　cycles　about　3-5　years.　Moreover,　lead-lag　analysis　between　precipitation　time-series　and　three　climate　indexes　(Nino　1　+　2　SST　index,　Nino　3　SST　index　and　SIOD　SST　index)　were　applied.　The　results　show　that　when　the　SSTs　lead　2　to　4　months,　they　are　highly　related　to　the　precipitation　in　the　coastal　areas　of　the　eastern　China.
