Precipitation distribution in Australia, is it mainly temperature or precipitation that determines t

From the north, east and south coast to the inland in a semi-circular decline Hope it helps you!

The main factors that determine the distribution of Australia's population are the favorable climatic conditions, including temperature and precipitation. The climate is cool and rainy.

At the same time, there are also factors such as flat terrain, colonists arriving first, developed economy, and convenient transportation.

The main thing is precipitation.

If you refer to the distribution map of Australia's climate types, you can see that the central part of Australia has less rain, while the southeast coast has more rain, so there are capitals and large cities.

In terms of temperature, the temperature difference between the whole country is not large, and it will not become a major factor in population distribution.

It is distributed in a semi-circular shape.

Australia straddles two climatic zones, with the northern part being tropical, and due to its proximity to the equator, January-February is the typhoon season. Southern Australia is temperate. The central and western regions of Australia are uninhabited deserts, with drought and little rainfall, high temperatures and large temperature differences; In the coastal zone, rainfall is abundant and the climate is humid.

Near the Tropic of Cancer is a tropical desert climate, with a savannah in the outer ring, a tropical rainforest climate in the northeast, a temperate maritime climate and a Mediterranean climate in the southeast corner, and a Mediterranean climate in the southwest corner.

Australia is located in the southern hemisphere, and although the time difference is only 2-3 hours from China, the seasons are completely opposite. Summer is from December to February, autumn from March to May, winter from June to August, and spring from September to November. The average annual temperature is 27 in the north and 14 in the south.

Characteristics of precipitation distribution in Australia: The basic characteristics of Australia's climate are the largest proportion of reed burial in arid areas, the semi-circular distribution of annual precipitation, and the general warmth and heat of the whole continent.

The arid zone has a large area and the highest proportion. With an average annual precipitation of 470 mm, the continent is the least of any continent except Antarctica, much less than Africa, and equivalent to only three-fifths of the average annual precipitation of all continents in the world. Areas with annual precipitation of less than 250 mm (10,000 square kilometers) account for the total area.

250,500 mm (10,000 square kilometers) of the total area of the continent; The area of more than 1,000 mm (10,000 square kilometers) is much smaller than that of Africa and South America, and it is also the smallest of the seven continents except Antarctica.

The Australian continent is part of the Australian Commonwealth. The Australian continent is surrounded by sea on all sides, and along with Antarctica, it is one of only two continents in the world that is completely surrounded by seawater. New Zealand is not part of the Australian continent.

The creatures on the Australian continent are very different compared to other continents.

Climate

Characteristics: The arid zone has the largest proportion, the annual precipitation is distributed in a semi-circular shape, and the whole continent is generally warm and hot. Australia's climate stretches from tropical to temperate, with average annual temperatures shifting from 27 in the far north to 13 in the south.

In temperate regions, the average annual temperature from December to the following year shifts from 27 in the far north to 13 in the far south.

Compared to other continents, Australia does not have an extremely cold or hot climate due to the absence of particularly high mountain ranges and the conditioning effect of the ocean. More than 40% of Australia's land is in the tropics. In the coldest regions, such as the highlands of Tasmania and the Australian ranges across New South Wales and Victoria in the southeast, there is frequent snowfall, and the winter weather often drops below freezing.

Australia's climate is characterized by the largest proportion of arid areas, semi-circular annual precipitation and generally warm and hot continents.

1) The arid area is vast and the proportion is the highest. With an average annual precipitation of 470 mm, the continent is the least of any continent except Antarctica, much less than Africa, and equivalent to only three-fifths of the world's average annual precipitation on all continents. Areas with less than 250 mm of annual precipitation (276.5 million square kilometres) account for 35.9% of the total area.

The area of 250 500 mm (249 140 thousand square kilometers) accounts for 32 4 per cent, and the two together account for 68 3 per cent of the total area of the continent; The area of more than 1,000 mm (51,360,000 square kilometres) accounts for only 6.5%, which is much smaller than Africa and South America, and is the smallest of the seven continents, except for the Antarctic finger.

2) The regional distribution of annual precipitation in Australia showed a semi-circular pattern that opened to the west, that is, it decreased from the north, east and south to the inland and western coasts. It is rainy in the north, with annual precipitation ranging from 1,000 to 2,000 mm, with Cairns in the north-east having the highest annual precipitation, with an average annual precipitation of 4,206 mm and a maximum of 5,360 mm, and the lowest near Lake Eyre in the Central Plains, less than 100 mm, or even below 50 mm. This distribution pattern is unique among continents.

3) The whole continent is generally warm and hot, especially in the summer, the heat in the inland areas is not as hot as in the Sahara Desert region. The hottest month of January is above 30 in three-tenths of the inland Midwest, 16 in central Tasmania and lowest in the Alpine region of the South East, but also around 10. As for the average maximum temperature in January, except for the northern part of the continent, which is rarely regulated by the monsoon, it is above 40 in both the north and south of the continent.

Extreme maximum temperatures are higher, such as 49 4 in Maburba, 53 in Kronkari and 55 in central Stiaat (135°E, 235°S), making it the hottest place in Oceania. In the inland area of 20° 23 degrees south latitude, the average daily temperature exceeds 32 2 consecutive days for more than 150 days, and some areas have a high temperature of 37 7 consecutive days for 64 days. Australia's winters are also quite warm compared to Africa and South America at the same latitude.

The average temperature of the whole continent in July is above 10, the 15 isotherm crosses the middle of the continent, the north is above 25, and the southeast mountain temperature is the lowest, which is also 8° 10, and only a few mountains can reach below 0. Extreme minimum temperatures, frost can be seen at night in inland areas, even dropping below 0 (e.g. -3 8 has been recorded in Alis Springs), and frost is rare even on the southern coast.
