Source sentences:
text: A severe thunderstorm needs a strong updraft and a strong downdraft.
text: Some severe thunderstorms develop a strong vertical updraft, commonly known as a mesocyclone.
text: If the updraft is strong enough, the droplets are held aloft long enough to become so large that they do not melt completely but fall as hail.
text: At times the updrafts are strong enough to extend the top of the cloud into the tropopause, the boundary between the troposphere (or lowest layer of the atmosphere) and the stratosphere.
text: Small ice particles and supercooled water droplets that are lifted into a thunderstorm by its updraft can combine, fall into the downdraft of the storm, and then, if the updraft is strong enough, be recycled back up above the freezing level in the storm.
text: The updrafts in thunderstorms can be very strong -- 50 knots or more -- which can help support the weight of hailstones as they grow.
text: Hail; if the updraft is strong enough to produce an overshooting top it can also carry large hail.
text: This also indicates that updrafts (rising air) within any thunderstorms could be strong enough to cause precipitation loading.
text: However, the updraft in a supercell is extremely strong, reaching estimated speeds of 150- 175 miles an hour.
text: Sometimes an updraft is so strong it suspends large amounts of these droplets and hailstones in the upper portions of the thunderstorm.
text: Overshooting Top - The area of clouds that "punch through" the jet stream into the lower stratosphere (occurs when updraft is particularly strong)
