Why is there a desert in Australia, which is surrounded by sea?

Australia, surrounded by sea, has deserts, which are mainly caused by Australia’s climate and unique terrain. Eastern Australia is affected by the warm air of the Pacific and mountains, and has sufficient rainfall so it has rich vegetation; Australia’s central The western region is affected by cold air, which results in very dry conditions and little rainfall. Therefore, many desert areas exist, and a large desert has been formed over thousands of years. Australia

Australia is an enviable place in the eyes of many people. It has the world-famous Great Barrier Reef, a variety of wildlife and unique natural scenery. The urban air is not polluted, and there are many When people immigrate, they always choose to go to Australia. But Australia is such a continent surrounded by sea, but there are large areas of desert in its central and western parts. Logically speaking, this phenomenon should not happen. So what kind of climate caused this situation? Effects of warm and cold air

The eastern region of Australia is a densely populated area, with most Australians concentrated in this area and also has large areas of forests and vegetation. First of all, let’s look at the air flow. The warm air moving from the Pacific Ocean just touches the eastern part of Australia, making the air in this area warmer and humid. The warm air will rise upward, and when it encounters the cold air at high altitude, it will condense into water and bring water. Rainfall, which results in abundant rainfall and humid climate in eastern Australia, making it easy for vegetation and various animals to survive; the west coast and central and western regions of Australia are affected by the cold air from the Indian Ocean, and the cold air will settle on the surface and will not form Rainfall will also lead to a dry climate in this area. Low rainfall and dryness will, over time, form a desert in the central and western parts of Australia. Unique topographic influence

There is a north-south Great Dividing Range in the coastal area of ??eastern Australia. When the warm air flow that can bring rainfall passes here, the Great Dividing Range will cause the warm air flow to rise and form rainfall, and it also blocks the warm air. The flow moves to the central and western parts of Australia, so there is very little rainfall in the central and western parts of Australia, forming a desert.
