How can oceans affect weather

Closer to the ocean, the air and water temperature stay pretty balanced because they are constantly exchanging thermal energy.

That is why coastal regions usually experience more temperate climates. Scientists use satellites, as well as instruments on boats and buoys in the water, to map surface water temperatures in the ocean.

These maps help us understand the way ocean currents move and how they affect climate. A preview of each game in the learning objective is found below.

The ocean is also very effective at absorbing and storing heat. These two factors play a big role in how the ocean impacts our weather. For example, because the ocean releases heat more slowly than land, coastal areas tend to be more temperate.

This great reservoir continuously exchanges heat, moisture, and carbon with the atmosphere, driving our weather patterns and influencing the slow, subtle changes in our climate. 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 years.

The oceans absorb much of the solar energy that reaches earth, and thanks to the high heat capacity of water, the oceans can slowly release heat over many months or years. The oceans store more heat in the uppermost 3 meters 10 feet that the entire atmosphere, the key to understanding global climate change is inextricably linked to the ocean. Let's look at some of these processes. At the end of the last ice age, about 15, years ago, and the ice sheets melted away and climate warmed at that time.

Ice sheets began to grow, and climate cool about , years ago at the beginning of the last ice age. About 15, years ago, this process was reversed as more sunlight reached areas near the Arctic Circle, and Earth emerged from the ice age. Still recovering from the ice age, global sea level continues to rise. The past century alone has seen global temperature increase by 0.

Is this just part of the natural cycle? How much of this warming is due to the burning of fossil fuels? Is human nature affecting Mother Nature? What should we do? Our response to the challenge of global warming begins by formulating the right set of questions. The first step in addressing the issue of global warming is to recognize that the warming pattern, if it continues, will probably not be uniform. The term "global warming" only tells part of the story; our attention should be focused on "global climate change.

Some spots will warm, while others will cool; these changes, and the accompanying shifts in rainfall patterns, could relocate agricultural regions across the planet. By studying the oceans from space, we can unlock a vast store of information about our changing environment. Climate is affected by both the biological and physical processes of the oceans. In addition, physical and biological processes affect each other creating a complex system.

Both the ocean and the atmosphere transport roughly equal amounts of heat from Earth's equatorial regions - which are intensely heated by the Sun - toward the icy poles, which receive relatively little solar radiation. The atmosphere transports heat through a complex, worldwide pattern of winds; blowing across the sea surface, these winds drive corresponding patterns of ocean currents.

But the ocean currents move more slowly than the winds, and have much higher heat storage capacity. The winds drive ocean circulation transporting warm water to the poles along the sea surface. As the water flows poleward, it releases heat into the atmosphere. In the far North Atlantic, some water sinks to the ocean floor. This water is eventually brought to the surface in many regions by mixing in the ocean, completing the oceanic conveyor belt see below. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel.

Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset. The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe.
