In Japan, strong winds generally appear when an atmospheric depression was caused by Typhoon or extratropical storm. In this paper the air density is shown as a function of the atmospheric pressure and temperature. The air density distributions near ground in severe storms have been clarified using meteorological data during recent ten years which have been observed by the Japan Meteorological Agency. The recommendation of the air density for the structural design on buildings and structures is obtained as ρ0 = 1.18(kg/m3); V10 ≥ 25m/s, ρ0 = 1.45-0.008V10(kg/m3); 10 ≤ V10< 25m/s, where ρ0 means the air density at sea level and V10 means the wind velocity at 10m high above the ground. It has also been clarified the air density dose not almost change by humidity or some rain drops.
