protection from automatic fire suppression systems. When the exterior facade material catches fire, the fire is easily affected by the atmospheric wind environment. Figure 1 shows a fire that occurred on the exterior of a telecommunications building in Changsha, China, resulting in a large amount of fire and thick smoke at the scene. In addition, facades have relatively weak fire separation measures. As a result, facade fires are characterized by easy ignition, rapid spread, and difficulty in suppression and control, creating a tendency to develop into large-scale fires. These characteristics distinguish facade fires significantly from common indoor building fires. Facade fires in high-rise buildings are highly susceptible to atmospheric conditions. Factors such as the wind direction, wind speed, wind pressure, and temperature significantly impact the spread characteristics of facade fires. This is especially pronounced in strong wind environments, where fires tend to spread in a leapfrogging manner, resulting in large-scale fires with unpredictable and irregular burning patterns. Strong winds can also cause the exterior insulation materials to detach and may even lead to the collapse of structures, complicating the efforts of firefighters performing elevated operations. Therefore, studying facade fires in high-rise buildings under strong wind conditions is of par-amount importance. Regarding the influence of external environmental wind on facade fires, [PERSON] et al. [1] conducted scaled experiments to investigate the variation in flame height ejected from the windows of exterior walls under the coupling effects of sidewalls and environmental wind. By changing the distance between sidewalls and wind speed, the study revealed that the flame height on exterior walls increases as the distance between sidewalls decreases, and decreases as wind speed increases. A new air entrainment model was proposed to describe the air entrainment behavior of facade flames under the coupling effects of sidewalls and environmental wind. [PERSON] et al. [2] proposed formulas for calculating wind speeds at different heights in different cities. [PERSON] et al. [3] used the FDS numerical simulation method to study the impact of outdoor wind speed on the movement characteristics of smoke in staircases of a high-rise building. By varying the fire source power and horizontal wind force in the simulations, they determined the horizontal smoke movement patterns within the staircase and analyzed the relationship between the chimney effect and horizontal wind direction, as well as the combined impact of the chimney effect on fire activity in horizontal corridors. [PERSON] et al. [4] conducted small-scale experiments to study the impact of windward external environments on fire characteristics in high-rise buildings' interconnected shafts and corridors, revealing the mechanisms of external wind

[5] studied the random characteristics of fires in dual-opening rooms of high-rise buildings under the influence of windward conditions. They also explored gas movement patterns between dual-opening cavities under the influence of backwinds and the changes in mass loss rates during gas combustion, and investigated gas flow conditions at cavity openings under different external wind influences. [PERSON] et al. [6] studied the development trends of fires and smoke plume movement characteristics in buildings with special structures under different wind speeds. [PERSON] et al. [7] found that external wind affects the pressure difference between the upper and lower sides of symmetrical openings in high-rise buildings. When wind speeds are high, wind pressure controls the change in pressure difference. [PERSON] et al.
