Abstract: According to the concept of turbulivity, this article using the data of earth surface temperature, air temperature and wind velocity from the National Weather Station have calculated the turbulivity and found the relationship between the factors of forest fire hazard and the numbers of the forest fire occurred. The result shows that the turbutivity one meter above the surface has the positive corelation to the forest fire hazard.The results of the calculation can also be used as a indicative signal of forest fire.
