The　spread　of　fires　on　the　facades　of　high-rise　buildings　is　highly　influenced　by　atmospheric　wind　conditions,　particularly　in　strong　wind　environments.　A　strong　wind　environment　refers　to　the　situation　where　the　wind　speed　reaches　level　6　or　above,　or　the　wind　speed　is　between　10.8　m/s　and　13.8　m/s.　We　conducted　an　in-depth　study　of　the　characteristics　of　flame　spread　on　the　facades　of　high-rise　buildings　under　strong　wind　conditions.　A　nested　coupling　method　based　on　WRF　(Weather　Research　and　Forecasting)　and　CFD　(computational　fluid　dynamics)　software　(Ansys　Fluent　2021)　was　used.　The　mesoscale　meteorological　simulation　software　WRF　was　utilized　to　obtain　regional　airflow　variation　data　within　a　radius　of　2　km　around　the　high-rise　building.　Subsequently,　these　data　were　coupled　with　the　CFD　software　(Ansys　Fluent　2021)　to　simulate　and　obtain　realistic　wind　field　data　within　a　400　m　range　around　the　building.　Finally,　these　realistic　wind　field　data　were　used　for　FDS　(Fire　Dynamics　Simulator)　fire　simulations　and　model　experiments　to　accurately　replicate　building　fire　scenarios　under　strong　wind　conditions.　The　results　indicate　that　using　grid　nesting　for　boundary　condition　division　would　help　to　improve　the　accuracy　of　fire　spread　characteristics　on　the　facades　of　high-rise　buildings　under　strong　wind　conditions.　For　a　high-rise　building,　both　headwinds　and　tailwinds　promote　vertical　and　horizontal　flame　spread,　with　a　more　significant　impact　on　vertical　flame　spread　speed.　Side　winds　enhance　horizontal　flame　spread　but　inhibit　vertical　flame　spread.　These　findings　provide　a　reference　for　the　effective　design　of　fire　protection　systems　for　the　facades　of　high-rise　buildings.
