What is a desert settlement?

Surrounded by the sea, Australia has deserts, which are mainly caused by Australia's climate and unique terrain. The eastern part of Australia is influenced by the warm air and mountains in the Pacific Ocean, with abundant rainfall, so it is rich in vegetation. The midwest of Australia is affected by cold air, which is very dry and has little rainfall, so there are many desert areas, which have formed a large desert for 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 wild animals and unique natural scenery, and the urban air is not polluted. Many people choose to go to Australia when they immigrate. But it is such an Australian continent surrounded by the sea, in which there is a large desert in the west. According to the truth, this phenomenon should not happen. What kind of climate caused this situation?

The influence of cold and warm air The eastern part of Australia is a densely populated area, where most Australians are concentrated, and there are also large areas of forests and vegetation. First of all, from the point of airflow, the warm air flowing from the Pacific Ocean just touches the eastern part of Australia, which makes the air in this area warmer and wetter, and the warm air will rise. When it meets cold air at high altitude, it will condense into water, bringing rainfall, which leads to abundant rainfall and humid climate in eastern Australia, and vegetation and various animals naturally live easily. In the west coast and midwest of Australia, affected by the cold air in the Indian Ocean, the cold air will settle on the surface without forming rainfall, which will also lead to dry climate in this area. After a long time, deserts will form in the midwest of Australia.

Due to the unique terrain, there is a north-south watershed in the offshore of eastern Australia. When the warm air flow that can bring rainfall passes through here, the watershed will make the warm air flow rise to form rainfall, and at the same time prevent the warm air from moving to the central and western Australia, so there is little rainfall in the central and western Australia, forming a desert.
