The tropical cyclones with maximum sustained surface winds of 33 ms are called

tropical depressions
tropical storms
hurricane
None of the above

The correct answer is: B. tropical storms.

A tropical storm is a tropical cyclone with maximum sustained surface winds of 33 to 63 miles per hour (53 to 101 kilometers per hour). Tropical storms are given names by the World Meteorological Organization (WMO). The names are chosen in advance from lists of six lists of 21 names each. The lists are used in alphabetical order, and the names are reused every six years, except for names that are retired after a particularly destructive storm.

Tropical storms can cause significant damage to coastal areas. The strong winds can damage buildings and trees, and the heavy rains can cause flooding. Tropical storms can also spawn tornadoes.

If you live in an area that is prone to tropical storms, it is important to have a plan in place in case a storm hits. You should have a disaster kit that includes food, water, and other supplies. You should also know where to go if you need to evacuate.

Here is a brief explanation of each option:

  • A. Tropical depressions are tropical cyclones with maximum sustained surface winds of less than 39 miles per hour (63 kilometers per hour). Tropical depressions are not given names.
  • C. Hurricanes are tropical cyclones with maximum sustained surface winds of 64 miles per hour (103 kilometers per hour) or more. Hurricanes are given names by the WMO.
  • D. None of the above is not a correct answer.
