The Great Sandy Desert, is located in the North West of Western Australia. 20.0000° S, 125.0000° E.
what causes the desert dryness?
The circulation of air between the hot equator and the cold poles creates areas of different atmospheric pressure known as the pressure belts. Low-pressure belts are found near the equator where the air is warmed by the sun, forcing it to rise. The air cools and starts sinking as it moves towards the poles.
When the air reaches the subtropical latitudes of about 25-30 N and 25-30 S it sinks, causing the high air pressure on earths surface. The sinking air is dry because the moisture has already been realised over the tropical rainforests at the equator. High-pressure systems bring fink, calm and sunny conditions and very little rainfall- the typical atmospheric conditions in deserts.
Info
Atmospheric processes take place in the Great Sandy Desert mainly caused by winds going 300 kilometres per hour! The wind can blow as far as 1000 kilometres and can carry a lot of sand at once. But it isn't always like this sometimes the wind can be quite calm but most of the time it's very harsh.
