VALUTAZIONE

DEL PRODOTTO

DEL PROCESSO

The classification system for tornadoes is called The Fujita Scale (or F scale), and it's an F0 to F6 categorization of the tornado's intensity.

Each category expresses the intensity in miles per hour.

Example: category F0 (40–72 mph; includes damages to trees, chimneys, and billboards).

Type in the other 5 categories.

PRESENTAZIONE

FASE 1

Tornadoes are local storms of short duration (this ranges between 5 and 10 minutes) formed of winds that rotate at very high speeds, usually in a counter-clockwise direction.
A tornado's characteristics:

• Time of day: they usually occur in the afternoon (3 - 7 PM)
• Direction: usually from southwest to northeast
• Length of path: this is the distance it travels; the average is 4 miles, but it could also travel around 300 miles.
• Width of path: averages between 300 and 400 yards but tornadoes have cut paths a mile or more in width.
• Speed of travel: though speeds of 68 mph have been reported, the average speed is somewhere between 25 and 40 mph.
• Cloud: dark cumulonimbus (thunderstorm cloud) from which the funnel-shaped pendant extends to the ground.
• Precipitation: rain and hail before the tornado hits and heavy downpour to the side of the tornado's path.
• Sound: roaring, rushing noise.
