How do the warm and cold currents affect the temperature of the land near them?

How do the warm and cold currents affect the temperature of the land near them?

Warm currents heat the air over the ocean and bring higher temperatures over land. Cold currents can lower air temperatures and can bring colder temperatures over land. Thus the temperature of California’s coastal cities is relatively cool.

What happens when cold and hot currents come together in the ocean?

This is because air above the warm currents is warm which contains water vapour. When this warm current meet the cold current, the air above the cold current, causes the water vapour of the warm current to condense into tiny particles which form fog.

How do ocean currents help regulate the temperature of the earth?

Ocean currents act much like a conveyer belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface.

Do ocean currents increase or decrease temperature?

How do ocean currents alter temperature? Ocean currents help move heat around the globe while absorbing and retaining the heat from the sun to keep the Earth warm and more evenly distribute the warmth from the sun.

How do cold ocean currents affect deserts?

Cold ocean currents contribute to the formation of coastal deserts. Air blowing toward shore, chilled by contact with cold water, produces a layer of fog. This heavy fog drifts onto land. Although humidity is high, the atmospheric changes that normally cause rainfall are not present.

How ocean currents influence the weather and climate of South Africa?

The Agulhas Current transports warm tropical Indian Ocean water southwards along the South African coast. It modulates the rainfall along the east coast and interior regions of South Africa by providing the latent heat of evaporation needed for onshore wind systems to pick up moisture and carry it inland.

What happens when warm and cold currents is important for fishes?

Answer: Some of the world’s most productive fishing grounds are located where warm and cold currents converge. For example, where Labrador current (cold) and Gulf stream (warm) meet, a dense fog is there and it is one of the richest fishing grounds of the world. When they meet the food of fishes is formed.

What happens when warm and cold currents meet how is it important for fisheries Class 9?

By meeting the warm and cold currents, a large amount of fog is created, which controls the temperature conditions in the fishing regions of the meeting grounds.

How do rising ocean temperatures affect the environment?

The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures. Increasing ocean temperatures affect marine species and ecosystems. Rising temperatures cause coral bleaching and the loss of breeding grounds for marine fishes and mammals.

How do ocean currents affect the temperature?

Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate. The ocean doesn’t just store solar radiation; it also helps to distribute heat around the globe.

What is cold currents and warm current?

Those currents that flow from the Equator towards the poles are warmer than the surrounding water and so they are called warm currents. The ocean currents that flow from the polar areas towards the Equator are cooler compared to the surrounding water, so they are called cold currents.

How do cold currents form in the desert?

Cold currents form deserts by cooling the air above them. By doing this, they reduce the capacity of the air to hold humidity, and this results in the water falling as rain over the sea before it gets to land. This leaves the land adjacent to a cold current being arid, and eventually, it becomes a desert.
