We observed the shapes of flames of alcohol burning in small circular dishes in the wind (2～12m/s).
The effect of the wind on the burning depended on the length to the direction of the wind i. e. the diameter of the circular dishes in this case.
As the speed of wind was increased, the following tendencies could be seen :
1. The flame length decreases, the flame temperature becomes higher just above the flame base, and the burning speed becomes greater, while the temperature of the flame-end becomes lower.
2. When the wind velocity increases as much as showing its cooling effect to combustion, the above-mentioned quantities tend to their limiting values and combustion becomes unstable.
