Did you know?
WebThe main features of a mature thunderstorm includes updrafts, downdrafts, overshooting tops, and an anvil. An overshooting top occurs at the top of the thunderstorm. Overshooting tops are dome-shaped as a result of strong updrafts in intense thunderstorms reaching the tropopause and pushing upward into the stable region. ... Supercells form ... There are several ways that an updraft of warm moist air can form. Sometimes air is forced up the side of a mountain. Air is also forced upward at weather fronts, where warm and cool air masses collide. But often, updrafts form without a mountain or front to guide them — just because warm air rises. See more When warm, moist air moves upward in an updraft, puffy cumulus clouds may form in the atmosphere. The moisture in the air condenses into water … See more As the cumulus cloud continues to grow, the tiny water droplets within it grow larger as more water from the rising air is added to the droplets. The cloud starts to look dark and gray as more water is added to it, and the growing … See more When the downdrafts in the cloud become stronger than the updrafts, the storm starts to weaken.
