Answer 4

tropical disturbance

Question 5

As the surface wind strengthens and creates an efficient flow around and into the center of the storm, it has now become a

Question 18

refers to an increase in the sustained winds over a short time interval.

Answer 18

Squall

Question 19

can also be formed which is expected for about half of the storms of tropical storm (TS) intensity

Answer 19

abnormal rise of water due to tropical cyclones is another disastrous hazard.

Answer 21

Storm surge

occur locally, the least destructive and only last for a short amount of time.

Answer 23

Air-mass thunderstorms

are a violent type created from a huge upward current of warm air.

Answer 24

Supercell thunderstorms

Answer 27

A flash flood

Question 28

occurs when a large amount of rain falls over a large area for days or weeks

Answer 31

Nonstructural responses

Question 32

The Four Phases of Disaster Reduction

Answer 32
