downdraft storm - EAS
- The wind danger related to thunderstorms is associated with the downdraft, a storm-scale flow of air descending towards the ground from several thousand feet above the surface. Particularly strong downdrafts are referred to as downbursts and are further sub-categorized based upon the size of the affected area and the duration of the peak wind.

- When the downdrafts in the cloud become stronger than the updrafts, the storm starts to weaken. Since warm moist air can no longer rise, cloud droplets can no longer form. The storm dies out with light rain as the cloud disappears from bottom to top. The whole process takes about one hour for an ordinary thunderstorm. Severe thunderstorms like supe...
