Web10. Thunderstorms. Two characteristics of thunderstorms make them an important element in fire weather. The first is the fire-starting potential caused by lightning strikes from cloud-to-ground. The second is the thunderstorm downdraft which spreads out upon nearing the ground, producing strong, shifting, and gusty winds for a short time. WebIf radiative cooling maintains a cloud against the warming and drying effects of subsidence, then a reduced rate of net radiative cooling could lead to dissipation of a cloud layer. Curry et al. (1988) pointed out that the air above cloud top is often quite moist, thus the drying effects of subsidence are reduced.
