Why are hurricanes considered wicked weather?

     A hurricane is a storm system characterized by a large low-pressure center and a lot of thunderstorms that produce strong winds and heavy rain. Hurricanes are also referred to as "tropical cyclones". Hurricanes get stronger when water evaporated from the ocean is released as the saturated air rises.


     The different sizes of hurricanes are:
  • Less than 2 degrees latitude. Which is very small/midget.
  • 2 to 3 degrees latitude. Which is small.
  • 3 to 6 degrees latitude. Which is medium/average.
  • 6 to 8 degrees latitude. Which is large anti-dwarf.
  • Over 8 degrees latitude. Which is very large.

Why is lightning considered wicked weather?

     Lightning is an atmospheric discharge of electricity accompanied by thunder, which typically occurs during thunderstorms. A leader of a bolt of lightning can travel at speeds of 220,000 km/h (140,000 mph). It can also reach temperatures approaching 30,000 °C (54,000 °F).


     There are many types of lightning. Some are:
  • Cloud-to-ground lightning
  • Bead lightning
  • Ribbon lightning
  • Dry lightning
     Cloud-to-ground lightning is the best known and second most common type of lightning. It has the greatest threat to life and property since it strikes the ground. Bead lightning is a type of cloud-to-ground lightning which appears to break up into a string of short, bright sections, which last longer than the usual discharge channel. Ribbon lightning occurs in thunderstorms with high cross winds and multiple return strokes. Dry lightning is lightning that occurs with no precipitation at the surface. It's usually the most common natural cause of wildfires.

Why are tornadoes considered wicked weather?

     A tornado is a violent, dangerous, rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud. They can also, in rare occasions, be cumulus clouds. Tornadoes are formed when two air masses meet together. Some tornadoes can be formed with other weather. Such as hail. Tornadoes are also one of the most destructive tragic disasters.


     There are six types of tornado ratings:
  • F0: 40-72 mph
  • F1: 73-112 mph
  • F2: 113-157 mph
  • F3: 158-206 mph
  • F4: 207-260 mph
  • F5: 261-318 mph
  • F6: 319-379 mph
F0 is the smallest and least destructive. F6 is the largest and most destructive.



     Tornadoes normally rotate cyclonically in direction. Which would be, counterclockwise in the northern hemisphere and clockwise in the southern.
