Fetid was a child of the Latin word fetidus, and dates back to the early 15th century, as does its cousin (now in disuse), fetor. Reek, which originally was a verb meaning âto smoke,â took on the connotation of âto smell badâ in the 17th century.
A F4 tornado has a maximum speed of 260mph (418 kph). However it should be noted that the wind estimates of the original Fujita scale, which were meant to correlate with damage levels, have been found to be inaccurate. on the new Enhance Fujita scale the top estimated wind speed for an EF4 tornado is 200 mph.
The strength of tornadoes is measured using the Fujita Scale, it ranges from F0 to F5 where F0 tornados cause minimal damage and F5 tornados cause massive damage. Most tornadoes have wind speeds that are less than 100 miles per hour or 161 km per hour. Massive tornadoes can reach wind speed of over 300 miles per hour or 483 km per hour.
