Final answer:
The levels of tropical cyclone intensity from weakest to strongest are tropical disturbance, tropical depression, tropical storm, and hurricane.
Step-by-step explanation:
Sorting the levels of tropical cyclone intensity from weakest to strongest based on wind speed, the order is as follows:
Tropical disturbance
Tropical depression: with wind speeds between 25 and 38 miles per hour
Tropical storm: once the winds reach a sustained speed of 39 to 73 miles per hour; named at this stage
Hurricane: classified as such when winds reach a sustained speed of 74 miles per hour or higher
'Hurricane', 'typhoon', and 'tropical storm' are regionally-specific names for tropical cyclones, which are storm systems characterized by low pressure centers, strong winds, and heavy rains.
These tropical cyclones tend to occur in areas where water temperatures are warmer than 80 °F, which allows the air to heat and rise rapidly, leading to the formation of such systems.
