An essay on atmospheric circulation and global energy balance

The radiation balance of the earth and its atmosphere is shown in Fig. It is varying of the slopes and heights which changes the rate of non-radiative energy flows up from the surface and thereby negates the thermal effect of greenhouse gases.

It is a thick layer of odourless, colourless and tasteless gases held to the earth by the force of gravity. I will focus on composition changes involving greenhouse gases though other composition changes are possible.

CO2 molecules are heavier than air and would be expected to be densest near the surface. Solow and other growth theorists working with this approach did derive some predictions about rates of economic growth.

Within the next decade, an experimental global water and energy cycle observation system combining environmental satellites and potential new exploratory missions - i. Starting with real weather data for a particular day, the computer solved all the equations for how the air should respond to the differences in conditions between each pair of adjacent cells.

Water sinks in the North Atlantic, traveling south around Africa, rising in the Indian Ocean or further on in the Pacific, then returning toward the Atlantic on the surface only to sink again in the North Atlantic starting the cycle again.

This deflection air is to the right in the northern hemisphere, and to the left in the southern hemisphere. Cold air from the polar regions falls down and then is heated up and pushed upward with the westerlies. The earth is at thermal equilibrium; however, there can have a surplus or deficit of energy in parts of the heat budget.

Additionally, GHGs are capable of radiating directly out to space which is an ability almost completely lacking in Nitrogen, Oxygen and Hydrogen. On land the situation is considerably more complex, and includes the deposition of rain and snow on land; water flow in runoff; infiltration of water into the soil and groundwater; storage of water in soil, lakes and streams, and groundwater; polar and glacial ice; and use of water in vegetation and human activities.

It would be decades before people began to argue that modelers were creating an entirely new kind of science; to Charney, it was just an extension of normal theoretical analysis. Scientists monitor the relationship between these two primary processes in the oceans.

An IAM breaks up the task of analyzing climate change into three "modules", which the Nobel committee describes in this way: Another major contributing factor to the circulation of the air is due to the subtropical highs.

On the other hand anticyclones are characterized by high pressure because they have diverging air that is descending. The global energy balance is an equal balance of short-wave radiation coming into the atmosphere and long-wave radiation going out of the atmosphere.

Atmosphere: Essay on Atmosphere (1560 Words)

This approach was clearly useful, and also clearly limited. Clouds, on the other hand, do exert a blanketing effect similar to that of the greenhouse gases; however, this effect is offset by their reflectivity, such that on average, clouds tend to have a cooling effect on climate although locally one can feel the warming effect: Deforestation, soil erosion, etc.

His theoretical explanation laid the foundation for research on endogenous growth and the debates generated by his country-wise growth comparisons have ignited new and vibrant empirical research.

FAQ 1 What Factors Determine Earth’s Climate?

The energy content of such an atmosphere would be skewed towards the top with the molecules at the boundary of space containing both a full load of kinetic energy AND a similar amount of potential energy whereas those at the bottom would have kinetic energy only. It represents in a simple way how ocean currents carry warm surface waters from the equator toward the poles and moderate global climate.

Frozen water in the oceans, in the form of sea ice, will be examined with both AMSR-E and MODIS data, the former allowing routine monitoring of sea ice at a coarse resolution and the latter providing greater spatial resolution but only under cloud-free conditions.

Deep water returns to the surface in the Indian and Pacific Oceans through the process of upwelling. The lowest SSS occurs in temperate latitudes 40 - 50 degrees North and Southnear coasts and in equatorial regions and the highest SSS occurs at about 25 - 30 degrees North and South latitude, at ocean centers and in enclosed seas.

It exists because of the pressure gradient that is created by the temperatures. The reason that this happens is because of the rotation of the earth on its axis.

Cold air from the polar regions falls down and then is heated up and pushed upward with the westerlies. It would be well over a decade before the accuracy of computer forecasts began to reliably outstrip the subjective guesswork of experienced human forecasters.

So, in fact a radiatively inert atmosphere will still have a convective circulation, there will still be an energy exchange cycling adiabatically between surface and atmosphere, the entire mass of the atmosphere will be involved and the surface will be warmer than the temperature predicted by the S-B equation.

These transformations alter the reflectivity of earth’s surface and this, in turn causes changes in the energy balance and in local atmosphere circulation patterns. Changes in the water balance: A great quantity of river discharge is used for irrigation or to meet industrial needs.

Dynamics in Atmospheric Physics Chapman, S. (). An example of the determination of a minute periodic variation as illustrative of the law of errors. Dec 31,  · As the solar energy at the top of the atmosphere was ∼ W m −2, 62–63% reached the ground during the observational period.

This value is close to the global average, where the Earth’s surface absorbs ∼50% of solar radiation. Seamless Poleward Atmospheric Energy Transports and Implications for the A primary driver of the atmospheric circulation is the requirement to balance the global heat and energy bud-gets.

The sun–earth orbital geometry greatly determines. Studies the behavior of Earth's lower atmosphere, including an introduction to comparative planetology, atmospheric evolution, thermodynamics, dynamics, waves and turbulence, clouds, hurricanes, global circulation and global change.

The Ekman balance is important for forming weather patterns in the atmosphere (see Fig 9).

The atmospheric system and the greenhouse effect

At the Earth's surface, around an area of low pressure, air spirals in toward the center and converges. At the Earth's surface, around an area of low pressure, air spirals in toward the center and converges.
