What's the climate like in Australia?

Australia has a savanna climate in the north, a rainforest climate in the northeast and a savanna climate in the south.

Its climatic characteristics are that the central and western Australia is a barren desert, with drought and little rain, high temperature and large temperature difference; In coastal areas, there is abundant rainfall and humid climate. Australia is located in the southern hemisphere. Although the time difference between Australia and China is only 2-3 hours, the seasons are completely opposite. 65438+February-February is summer, March-May is autumn, June-August is winter, and September-165438+1October is spring. The annual average temperature in the north is 27℃, and that in the south is 65438 04℃.

Due to the difference of thermal properties between land and sea, the southeast monsoon prevails in Australia in winter. In summer, the pressure belt and wind belt move south, and the northeast monsoon in the northern hemisphere passes through the equator, forming northwest wind under the action of geostrophic deflector; The wind blows from the ocean to the land, bringing more precipitation and forming the rainy season.

Australia spans two climatic zones, and the north is tropical. Because it is close to the equator,1-February is a typhoon period. Southern Australia belongs to temperate zone. The midwest is an uninhabited desert, with drought and little rain, high temperature and large temperature difference; In coastal areas, there is abundant rainfall and humid climate.

The topography of Australia

The topography of the Australian mainland can be divided into three different terrain distribution areas: east, middle and west. The Australian continent is located in the Indian Ocean plate, so there are few tall landforms formed by plate movement. The geological age of the mainland mountainous plateau is very long. After a long period of external force, the surface of the Australian continent is a relatively undulating plain, and the overall elevation is not high, with an average elevation of only about 350 meters.

The topographic unit in the eastern part of the Australian mainland is a great watershed, which runs north and south and is basically parallel to the coastline. The total length is about 3000 kilometers, the width is about 160 to 320 kilometers, and the average height is about 800 to 1000 meters. Mount Kosiasco, which is 2230 meters above sea level, is its highest peak. The great watershed is an ancient mountain range. Under the long-term weathering and erosion of external forces, its height has been declining and its surface is undulating.
