Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What does monitoring a tropical storm involve?

    Model answer

    Tracking it with satellites and specially equipped aircraft that measure pressure, wind speed and rainfall as it grows.

  2. 2

    Why is a storm watched even before it threatens land?

    Model answer

    Watching it from the moment it forms shows how quickly it is strengthening, which gives forecasters the longest possible warning time.

  3. 3

    What is meant by prediction in the context of these storms?

    Model answer

    Using the monitoring data in computer models to forecast the likely track, strength and arrival time of the storm.

  4. 4

    Why is forecasting a storm's path difficult?

    Model answer

    A storm can change direction and intensity quickly, so a forecast becomes less reliable the further ahead it looks.

  5. 5

    What is a storm warning intended to achieve?

    Model answer

    It gives people time to evacuate, board up property and stock up on food, water and fuel before the storm arrives.

  6. 6

    Give two ways buildings can be protected against a storm.

    Model answer

    Raising homes on stilts above the level of flooding, and fitting reinforced sloping roofs and storm shutters over windows.
