Typhoon Dolphin

The name Yanyan was used to name one tropical cyclone in the northwestern Pacific Ocean. The name was contributed by Hong Kong and is a given name (Chinese: 欣欣; pinyin: Xīnxīn; Cantonese Yale: Yān-yān; literally: "Joyful"). It was part of a series of reduplicated female names from Hong Kong, like Tingting, Shanshan and Lingling.

During the 2004 ESCAP/WMO Typhoon Committee, Hong Kong requested to retire the name. Instead, the name was replaced by Dolphin to be used in future seasons.

The name Dolphin has been used to name two tropical cyclones in the northwestern Pacific Ocean. The name, also contributed by Hong Kong, refers to the Chinese white dolphin, a mascot in Kong Kong.
