Table 5 Kendall’s tau (τ) test and correlation of climate variables (diurnal temperature range, DTR; relative humidity, RH; minimum temperature, Tmin; maximum temperature, Tmax; average temperature, Tav; and wind speed, WS) to the forest fire incidents reviewed in our study of climate attributes and their affects on forest fire between 2002 and 2019, in the Dehradun district, state of Uttarakhand, India. Z-statistics and P-values are also given. ** = P ≤ 0.001, highly significant correlation; * = P ≤ 0.05, significant correlation; ns = non significant correlation
