Australia is so dry because we sit under the subtropical high-pressure belt, which encourages the air to push down, preventing the lift required for rain. Being under the high-pressure belt is enough to make it dry, but there are other systems called climate drivers that can make things worse from one year to the next.

Why does Australia have a dry climate in some areas?
Australia’s climate is governed mostly by its size and by the hot, sinking air of the subtropical high pressure belt (subtropical ridge). This moves north-west and north-east with the seasons.The northern part of the country has a tropical climate, varying between grasslands and desert.
What is the climate type in Australia’s interior?
The northern section of Australia has a more tropical influenced climate, hot and humid in the summer, and quite warm and dry in the winter, while the southern parts are cooler with mild summers and cool, sometimes rainy winters.
What causes dry climate?
Evaporation. Another characteristic of a dry climate is that evaporation is often greater than precipitation. This results in a climate that lacks ground moisture due to the low average rainfall and rapid evaporation of the precipitation that does fall.
Is Australia a dry country?
Australia is the driest inhabited continent in the world; 70% of it is either arid or semi arid land. The arid zone is defined as areas which receive an average rainfall of 250mm or less. The semi arid zone is defined as areas which receive an average rainfall between 250-350mm.
Why is Australia the driest continent?
Australia is the second-driest continent in the world, with mean annual rainfall less than 600mm for more than 80 per cent of Australia. Australia is so dry because we sit under the subtropical high-pressure belt, which encourages the air to push down, preventing the lift required for rain.
Why is Australia prone to drought?
Australia is prone to drought because of its geography. The continent is located under the subtropical high pressure belt which is an area of dry, stable air and clear skies. Areas of the continent such as the far north and south receive reasonably regular rain and the east coast receives moisture from the ocean.
Which part of Australia receives the most moisture?
Rainfall in Australia tends to decrease as you move from north to south, and as you move from the east coast to the interior. So the areas of high rainfall tend to generally occur in a curve from the north of the continent, then around to the east side, then down to the south.
Where are the driest climates found on Earth?
The driest place on Earth is in Antarctica in an area called the Dry Valleys, which have seen no rain for nearly 2 million years. There is absolutely no precipitation in this region and it makes up a 4800 square kilometer region of almost no water, ice or snow.
Where is best climate in Australia?
Port Macquarie has, according to the CSIRO, the best climate in Australia, with mild winters and gentle summers, and water warm enough to swim in for most of the year. Thousands of holidaymakers who flock here each summer to bask in the sunshine on a string of beautiful beaches agree.
What is dry climate in geography?
The Dry Climates (Group B) have less precipitation than evaporation. Dry climate zones cover about 26 percent of the world’s land area. What climate characteristics is the dry climate group likely to have? Temperature: Abundant sunshine.
Does a dry climate have seasons?
There are only 2 seasons: wet season (summer) and dry season (winter). Usually the dry season is longer. During the dry seasons plant life and animal life suffers, but as the rainy season begins life flourishes in this area. This climate is caused by changing wind and ocean currents.
How would you describe dry weather?
Related Definitions
Dry Weather means those days with less than 0.1 inch of rainfall, and occurring more than three days after a Rain Day. Dry Weather means a twenty-four (24) hour period with no more than one-tenth of an inch of rainfall, preceding a combined sewer overflow event.
Does snow fall in Australia?

What is the driest country?
Australia is, therefore, the world’s driest inhabited continent on earth. Australia is also the smallest continent occupying a land mass of about 2.97 million square miles which is about 5% of the Earth’s land mass, as well as the lowest and flattest continent.
Does Australia ever snow?
It’s a little-known fact to those who are not from there, but it does snow in some parts of Australia.Snow in Australia happens for three months every year in some parts of the south, turning them into winter wonderland destinations for locals and tourists alike.

Why is Australia considered as oldest flattest and driest continent in the world?
The reason why Australia is the flattest continent is due to the large plateau covering most of the central part and forms the largest area of the continent.Besides being the flattest continent, Australia is the smallest continent in the world, and apart from Antarctica, it is the driest.
What is the driest state in Australia?
South Australia
South Australia is usually the driest state in Australia, with 2017 being no exception. Last year was actually a wetter than usual rainfall year for South Australia, with an average rainfall of 248.9mm, which is 11% above the long term average for South Australia (the average again taken from 1961 – 1990).
Why does Australia have so many deserts?
The main reason for the formation of the Australian deserts is their location. Like most major deserts across the world the Australian deserts can be found around a certain latitude (roughly 30° north/south of the equator) where the weather phenomena create a dry climate: Hot moist air rises at the equator.
Does Australia have droughts?
Drought is a frequent visitor in Australia. The Australian Bureau of Meteorology describes the typical rainfall over much of the continent as “not only low, but highly erratic.” Over the last decade, drought has dominated Australian weather.
