What type of current is the west Australian current?
cold surface currentThe West Australian Current is a cold surface current that runs between the Southern Ocean and the Southern Indian Ocean. It begins with the Southern Indian Ocean Current, which is a component of the broader Antarctic Circumpolar Current (also known as the West Wind Drift).
Is the East Australian Current cold or warm?
warmThe East Australian Current sweeps warm water down the east coast of Australia. Like the Gulf Stream, the East Australia Current is pushed to the western edge of the ocean by the rotation of the Earth.
Is Perth near a warm or cold ocean current?
Ocean currents have a large impact on climate. For example, Perth receives most of its rainfall in autumn/winter due to the prevalence of the warm Leeuwin Current bringing warm water down our coast.

Are Western currents warm?
Western boundary currents, such as the Gulf Stream and Kuroshio Currents, are warm, deep, and fast moving surface currents that transport a lot of water and heat from the tropics to higher latitudes.
Is Perth the hottest city in Australia?
The hottest month is February, with an average maximum temperature of 31.6 °C (88.9 °F), which is the second highest monthly maximum of the Australian capital cities, only behind Darwin. Humidity during summer is usually low, with an average 3 pm dew point of 12.9 °C (55.2 °F) in February.
Why does Perth get so hot?
So what's behind it? Perth's Mediterranean climate owes much to the easterly winds travelling over the hot, dry desert. The winds are caused by anti-cyclones — or high pressure systems — which are a prominent feature on the weather charts we see almost every day for Perth and Western Australia.

Are eastern currents cold?
The Ocean General Circulation and Climate Also important for climate are eastern boundary currents, which occur in tropical and subtropical latitudes at the eastern margins of the oceans. These currents are generally cold, shallow, and broad in comparison to western boundary currents.
What type of current is the East Australian Current?
surface oceanic currentEast Australian Current, surface oceanic current, a section of the counterclockwise flow in the Tasman Sea, southwestern Pacific Ocean.
What climate is east Australia?
temperate climateThe eastern portion has a temperate climate, ranging from humid subtropical from its northern border to the Central Coast and most of Sydney, and oceanic to the south coast.
Does the east coast have warm currents?
The warm Gulf Stream originating in the tropical Caribbean, for instance, carries about 150 times more water than the Amazon River. The current moves along the U.S. East Coast across the Atlantic Ocean towards Europe.

What ocean current is located in the opposite direction of the Leeuwin current?
Ocean Currents surrounding Australia. The West Australian Current is located where the Leeuwin Current is labeled and flows in the opposite direction to the Leeuwin Current. The West Australian Current (or the Western Australian Current ), is a cool surface current of the Southern Ocean and Southern Indian Ocean .
Which current flows in the opposite direction?
In addition to the West Australian Current flowing on the Western Australian Coast, the Leeuwin Current and Southern Australian Countercurrent, also flow along this coast, with the former flowing in the opposite direction. These 3 currents together contribute greatly to the rainfall and climate in the southwest region of Western Australia.
Is the current in Australia seasonal?
As the current approaches Western Australia, it turns north, parallel to the western coast of Australia, and becomes the West Australian Current. The current is mainly seasonal, being weaker in winter and stronger in summer, and is affected by the winds in that area.
Which current moves warm water along the eastern coast of Australia?
The East Australian current moves warm water along the eastern coast of Australia; while the West Australian current moves cold water along the western coast of Australia, each either warming or cooling the climate on the nearby coast.
What is the current in Australia?
a cold current of the Indian Ocean along the western shores of Australia. It is the northern branch of the West Wind Drift. The current flows from south to north. Its temperature in February ranges from 19°C in the south to 26°C in the north; in August, from 15° to 21°C, respectively. Its salinity is 35.5-35.7 parts per thousand; its speed is 0.7-0.9 km/hr. In the tropics of the southern hemisphere, the West Australian Current becomes the South Equatorial Current.
What is the temperature of the current in February?
The current flows from south to north. Its temperature in February ranges from 19°C in the south to 26°C in the north; in August, from 15° to 21°C, respectively. Its salinity is 35.5-35.7 parts per thousand; its speed is 0.7-0.9 km/hr.
Where does the East Australian current flow?
Heat flux in the East Australian Current from the equator toward the South Pole. The EAC is a surface current driven by winds over the South Pacific. During different parts of the year these winds control how the current behaves. The EAC starts on the west edge of the South Pacific gyre where it collects warm, nutrient-poor water.
What is the largest ocean current in Australia?
At around 15° S near the Australian coast the SEC divides forming the southward flow of the EAC. It is the largest ocean current close to the shores of Australia. The EAC reaches a maximum velocity at 30° S where its flow can reach 90 cm/s. As it flows southward it splits from the coast at around 31° to 32° S.
How does EAC affect the Tasman Sea?
The EAC has nutrient-poor water but causes upwelling along the coastline. The eddies produced cause an increase in vertical mixing within the Tasman Sea. The process of producing, moving, and destroying eddies causes the thermocline layer to mix with the surface layer, bringing some nutrients up to the surface. The EAC and its eddies frequently flow onto the continental shelf and inshore, influencing circulation patterns and increasing mixing. Eddies aren't the only way the EAC brings nutrients to the surface. Features along the coast push the current further off shore. If there is a strong northerly wind, it will push the current even further off shore, allowing deep water to rise up the coast, bringing nutrients up to the surface.
What is the East Auckland Current?
The eastward movement of the EAC through the Tasman Front and reattaching to the coastline of New Zealand forms the East Auckland Current. The EAC also acts to transport tropical marine fauna to habitats in sub-tropical regions along the south east Australian coast.
What happens when the wind is strong?
If there is a strong northerly wind, it will push the current even further off shore, allowing deep water to rise up the coast, bringing nutrients up to the surface. The EAC experiences seasonal variations.

Why are ocean currents important?
Oceans are the lifeline of the Earth and humankind because it plays an important role in the Earth's climate and in global warming. It produces over half of the world's oxygen and absorbs 50 times more carbon dioxide than our atmosphere.
What are ocean currents made of?
Ocean Currents are made up of horizontal and vertical components of the circulation system of ocean waters that is produced by gravity, wind friction, and water density variation in different parts of the ocean.
What are the components of ocean currents?
