Interactions Between The Ocean And Oceans

Oceans are a prominent feature of earth’s environment, containing ninety-seven percent of the earth’s water 1.332 billion cubic kilometres (M.A. Charette and W.H.F. Smith., 2010,) which spans over almost three-quarters of the planet. Due to the variance of ocean sizes, the processes occurring in them vary greatly as well. Oceans are defined by borders that separate them or limits, the most basic being continental shelves that define where oceanic crust forms. There are currently five recognised oceans; the Pacific; Atlantic; Indian; Southern and the Arctic oceans. All of these oceans are connected to each other in some way and go on to categorise the world ocean which makes up the bulk of the hydrosphere. The oceans store huge quantities…show more content…
The distribution of energy creates atmospheric circulation; the atmosphere is in constant flux trying to achieve an equilibrium that won 't be reached therefore weather is continuously in a state of flux moving in a complex and dynamic manner that has many minor processes contributing to its state. Climate, on the other hand, refers to the average weather conditions of a given place. Like weather it does change but this is over a much larger period of time over longer periods of time usually 20-30 years. This can be the fact that the last ice age ended about 10,000 years ago is evidence that climate is more permanent when compared to short-term weather events like rainfall seasons. Earth 's atmospheric systems show complicated transfers of energy between the world oceans, the atmospheric cells and land masses. Heat flux is the term used to describe the interchanging of energy (heat) between 2 surfaces, here I will look at ‘Air-sea fluxes’ this is a key climatic process that influences oceanic and atmospheric circulation to drive weather events and the motion/behaviour of the world 's currents which disperse energy to more local climate systems. Take the bar chart below, (M. Gloor, 2001) As shown on the bar chart seas at or near the equator experience the most heat flux whereas the oceans further away from the equator receive less insolation and, therefore, have a more negative heat flux as most of the heat is transferred to the atmosphere.
