Abstract：Names have been given to tropical cyclones which raging through the western North Pacific Ocean since 1947. However, considering the disastrous impact or some extreme uniqueness quite a few typhoons have their names retired from the list. This study conducts preliminary analysis and summarizes the frequency, impact and also explains why they were retired. It shows that a total of 31 typhoons (in the western North Pacific Ocean) have been removed from the list from 1947 on, most of which retired after 2000 amounting to 20 as against 11 before 2000. Collectively, these retired typhoons have made 16843 people killed or missing and caused a heavy property loss of $45.7 billion, averaging 543 fatalities and property loss of $1.69 billion each (capping at 8000 and $10 billion respectively). Most typhoons were retired due to huge personnel and property loss. However, some others were removed for their unique feature such as developed near equator, extremely long typhoon tracks, etc. Moreover, there were some retired due to neither of the above reasons. In this connection, the study also discusses the standard of retiring typhoons.
