Q

Tornado

A

mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system.

22
Q

Tropical depression

A

A tropical depression forms when a low pressure area is accompanied by thunderstorms that produce a circular wind flow with maximum sustained winds below 39 mph. Most tropical depressions have maximum sustained winds between 25 and 35 mph.

23
Q

Typhoon weather

The same type of disturbance in the Northwest Pacific is called a “typhoon” and “cyclones” occur in the South Pacific and Indian Ocean. The ingredients for these storms include a pre-existing weather disturbance, warm tropical oceans, moisture, and relatively light winds.
