a data value associated with a feature or variable measure (‘field’) in a GIS layer

in GIS, a read-only display of attribute information, often linked to a location

information which has been tied to a particular location (geolocated), using an agreed system such as latitude and longitude

information which is tied to a particular point in time, so that data can be time-enabled (also known as spatiotemporal data)

Using GIS to map the track of a tropical storm

This unit teaches pupils about climate change (causes, impacts and responses) together with extreme weather events, specifically tropical cyclones.

Which of the following is **not** a layer that might be used in a GIS to analyse a tropical storm?

a data value linked to a feature or variable measure in a GIS layer

a read-only display of attribute information linked to a location

information tied to a particular location using an agreed system

information which is tied to a particular point in time

Match the lesson's key words with their definitions.

By predicting the weather using a formula

By collecting satellite and radar data to map the storm’s path

By making manual drawings of the storm's track

How do Geographers use GIS to track tropical storms?

It shows how deep the ocean is beneath the storm

It helps predict and map the storm’s path and impacts

It measures the temperature of the storm’s eye

Why is it useful to use GIS (Geographic Information Systems) to track a tropical storm?

Tropical storms require __________ water and __________ winds to form, they are found in tropical regions close to the equator.

The term for these storms changes, depending on where they occur. Match the term to its location.

Which of the following is **not** a typical feature of a tropical storm?

What type of data does GIS typically use to create maps?

Warm air rises from the ocean leaving an area of low pressure, which is filled

by the surrounding air, creating winds. This air now warms and rises too,

bringing moisture with it. This moisture cools and condenses to form towering

storm clouds which make the eye wall. When the cooled air descends it will

form an area of calm in the centre called the eye. Due to the winds near the

equator, the tropical storm starts to move from east to west.

The spin of Earth causes these winds to curve and the storm starts to spin.
