A fire that burns with a deficit of air, for example in a closed room or a room with small openings, is called a ventilation-controlled fire. If it is sufficiently hot in the room more pyrolytic gases, i.e. combustible gases, will be produced than what the fire can consume. WebWind Gust is a sudden, brief increase in speed of the wind. According to U.S. weather observing practice, gusts are reported when the peak wind speed reaches at least 16 knots and the variation in wind speed between the peaks and lulls is at least 9 knots. The duration of a gust is usually less than 20 seconds. norma shearer 1936 mayfair ball
