There are no conclusive radar target return characteristics which identify a tornado. However, tornadoes
may be present if the following characteristics are observed:
• A narrow, finger-like portion extends and in a short time curls into a hook and closes on itself.
• A hook, which may be in the general shape of the numeral 6 (numeral 9 in the southern hemisphere),
especially if bright and projecting from the southwest quadrant (northeast quadrant in the southern
hemisphere) of a major thunderstorm.
• V-shaped notches.
• Doughnut shapes.
These shapes do not always indicate tornadoes, and tornado returns are not limited to these characteristics.
Confirmed radar observations of tornadoes most often have not shown shapes different from those of a
normal thunderstorm display.
