Seawater density increases with depth too, because the sunlight that warms the ocean is absorbed at the surface, whereas the deep ocean is full of cold water. The change in density with depth is referred to by oceanographers as stability. The faster density increases with depth, the more stable the ocean is said to be.
How the ocean keeps the climate stable?
The oceans influence climate by absorbing solar radiation and releasing heat needed to drive the atmospheric circulation, by releasing aerosols that influence cloud cover, by emitting most of the water that falls on land as rain, by absorbing carbon dioxide from the atmosphere and storing it for years to millions of …
Why is the ocean more stable than the atmosphere?
“Water near the ocean’s surface is warming faster than the water below. That makes the oceans become more stable.” … “The ability of the oceans to bury heat from the atmosphere and mitigate global warming is made more difficult when the ocean becomes more stratified and there is less mixing,” said Mann.
How does the ocean affect the climate?
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.
Are ocean temperatures stable?
Below the thermocline the deep ocean temperature is fairly constant at about 2o C, continuing down to the bottom. There is little temperature change in the deep ocean, as it is far removed from significant heat sources, making it one of the most thermally stable regions on earth.
How does the ocean moderate the climate of downwind coastal areas?
The ocean has a moderate influence on the climate of downwind coastal areas because it helps keep the temperatures more moderate and predictable. It takes more energy to change the temperature of the ocean, so often the downward winds are exposed to more average temperatures coming from the ocean surface.
What does stable ocean mean?
When scientists talk about ocean stability, they refer to how much the different layers of the sea mix with each other. … It controls how heat, carbon, nutrients and dissolved gases are exchanged between the upper and lower layers of the ocean.
How does ocean pollution affect climate change?
Marine plastic pollution breaks down into microplastics and contributes to climate change both through direct GHG emissions and indirectly by negatively affecting ocean organisms. … The global warming potential of black carbon is up to 5,000 times greater than that of carbon dioxide (CO2).
What is the climate of a ocean?
An oceanic climate, also called a maritime climate, is a type of weather pattern. In an area with an oceanic climate, summers are cool and winters are cooler but not very cold. There is rain in the summer and rain and snow in the winter with no dry season. Oceanic climates are caused by wind patterns.
What effect does an ocean have on the climate quizlet?
Ocean currents affect world climate because ocean currents carry warm water, which helps warm climates of land masses.
How does ocean acidification affect climate change?
If acidification decreases marine emissions of sulfur, it could cause an increase in the amount of solar energy reaching the Earth’s surface, speeding up warming—which is exactly what the Nature Climate Change study predicts. It’s one more surprise that the oceans have in store for us.
Why does the temperature of ocean water vary?
The temperature of ocean water varies by location – both in terms of latitude and depth, due to variations in solar radiation and the physical properties of water.
Why is ocean water cold in the summer?
Cold, salty water is dense and sinks to the bottom of the ocean while warm water is less dense and remains on the surface. … Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface.
Why is sea water warmer at night?
Water loses and gains heat at a slower rate than the air does, so, at night, the water cools at a slower rate than the surrounding air and so feels warmer by comparison.
