In　order　to　determine　a　reasonable　value　of　basic　wind　speed　at　both　sides　of　Taiwan　Strait,　comparative　study　of　extreme　and　basic　wind　speed　under　different　climate　conditions　are　carried　out　in　this　paper.　The　measured　wind　speed　data　are　obtained　from　a　meteorological　station　in　Taipei　from　1961　to　2015.　The　extreme　and　basic　wind　speed　are　estimated　through　Gumbel　distribution　adopted　by　building　wind　resistant　design　standards　at　both　sides　of　the　Taiwan　Strait.　The　annual　maximum　wind　speed　sampling　method　and　typhoon　wind　speed　sampling　method　correspond　to　the　mixed　and　typhoon　climate　conditions,　respectively.　The　results　show　that,　for　the　identical　wind　speed　observation　data,　the　extreme　wind　speed　obtained　by　building　wind　resistant　design　standard　in　Taiwan　TB2015　is　slightly　less　than　that　obtained　by　current　national　building　wind　resistant　design　standard(GB50009)　in　Fujian,　and　the　basic　wind　speed　is　just　opposite,　but　the　estimated　wind　speed　difference　between　the　two　standards　is　very　small.　The　extreme/basic　wind　speed　under　typhoon　climate　is　larger　than　the　corresponding　value　under　mixed　climate,　and　is　closest　to　the　measured　extreme/basic　wind　speed　within　an　error　less　than　0.5%.　For　both　sides　of　the　Taiwan　Strait　severely　affected　by　typhoons,　the　estimated　wind　speed　under　typhoon　climate　condition　is　suggested　to　adopt　as　the　basic　wind　speed.　©　2021,　Editorial　Department　of　Journal　of　Hunan　University.　All　right　reserved.
