Radiation and heat transfer in the atmosphere
The atmosphere of the earth is heated by radiation which is mainly: [1]
The atmosphere of the earth is heated by radiation which is mainly:. A very small percentage of the atmospheric heat is due to re-radiation by land and water
How is the Atmosphere Heated? [2]
Earth’s atmosphere gets heated due to the following three critical processes: conduction, advection, and convection. The sun radiates energy in the form of heat and light in all directions which is called radiation
Convection is the movement of heat through air currents.. As discussed above, the atmosphere is heated by three important processes that are carried out Conduction, Convection, and Advection
Conduction: Heat transfers from items with a higher temperature to those with a lower temperature through this mechanism. The upper layers, which are in contact with the lower layers, as well as the air in contact with the soil eventually warm up.
The Earth’s Radiation Budget [3]
The energy entering, reflected, absorbed, and emitted by the Earth system are the components of the Earth’s radiation budget. Based on the physics principle of conservation of energy, this radiation budget represents the accounting of the balance between incoming radiation, which is almost entirely solar radiation, and outgoing radiation, which is partly reflected solar radiation and partly radiation emitted from the Earth system, including the atmosphere
The units of energy employed in measuring this incoming and outgoing radiation are watts per square meter (W/m2).. Incoming ultraviolet, visible, and a limited portion of infrared energy (together sometimes called “shortwave radiation”) from the Sun drive the Earth’s climate system
Larger aerosol particles in the atmosphere interact with and absorb some of the radiation, causing the atmosphere to warm. The heat generated by this absorption is emitted as longwave infrared radiation, some of which radiates out into space.

Atmosphere is transparent to short wavelength & opaque to long wave length.
The atmosphere of the earth is heated by the process of ________.a)Radiationb)Convectionc)Conductiond)EmissionCorrect answer is option ‘B’. Can you explain this answer? [5]
The atmosphere of the earth is heated by the process of ________.a)Rad…. – The atmosphere of the earth is heated by the process of convection.
It is a process by which heat travels through water, gas, air, or other liquids.. – In convection, the heat energy is transferred by the actual movement of the particles from one place to another
In this way, the atmosphere of our earth is heated by the process of Convection.. – Radiation is the propagation or emission of energy in the form of waves or rays.
How is the Atmosphere Heated? [6]
Earth’s atmosphere gets heated due to the following three critical processes: conduction, advection, and convection. The sun radiates energy in the form of heat and light in all directions which is called radiation
Convection is the movement of heat through air currents.. As discussed above, the atmosphere is heated by three important processes that are carried out Conduction, Convection, and Advection
Conduction: Heat transfers from items with a higher temperature to those with a lower temperature through this mechanism. The upper layers, which are in contact with the lower layers, as well as the air in contact with the soil eventually warm up.
The atmosphere gets heated by terrestrial radiation more than by insolation. Justify the statement. [7]
The atmosphere gets heated by terrestrial radiation more than by insolation. Hint: The night and day all over the world are equal in days, and the highest amount of insolation is obtained in the equator, and the amount of insolation falls in the direction of the poles
The sum of insolation obtained on the surface of the earth is much less than that radiated from the sun because of the small size of the earth and its distance from the sun.. Terrestrial radiation refers to radiation sources in soil, water and plants
Insolation is an incident of sunlight on any object. Specifically, it is a measure of solar energy that occurs in a given region over a defined period of time.
The atmosphere is heated or cooled by the following processes [8]
The atmosphere is heated or cooled by the following processes which have been briefly discussed here:. (1) Partial absorption of solar radiation by the atmosphere
Even then, the dust particles and water vapour present in the lower layers of the atmosphere directly absorb about 10 per cent of the incoming solar radiation.. About 50 per cent of this absorption occurs in the lower 2 km of air where most of the water vapour is found
That is why even on a clear sunny day, the temperature near the surface remains low. In winter, people enjoy the warmth of sunshine by sitting close to the side of a wall of their houses exposed to the sun, because the short-wave incoming solar radiation is being converted into long-wave terrestrial energy.
Heating and Cooling of the Atmosphere [9]
Conduction happens when two bodies with temperature differences are in touch with each other; there is a progression of energy from the hotter to the cooler body. The exchange of hotness goes on until both the bodies attain equal temperature
The air in touch with the earth rises on warming as it flows. This course of vertical warming of the environment is known as convection
So we shall learn about the process of cooling and heating the atmosphere.. There are unique approaches to the warming and cooling of the air
Heat Transfer in the Atmosphere [10]
Heat moves in the atmosphere the same way it moves through the solid Earth (Plate Tectonics chapter) or another medium. What follows is a review of the way heat flows and is transferred, but applied to the atmosphere
Heat radiates from the ground into the lower atmosphere.. In conduction, heat moves from areas of more heat to areas of less heat by direct contact
In the atmosphere, conduction is more effective at lower altitudes where air density is higher; transfers heat upward to where the molecules are spread further apart or transfers heat laterally from a warmer to a cooler spot, where the molecules are moving less vigorously.. Heat transfer by movement of heated materials is called convection
The atmosphere of the Earth primarily get heated due to which of the following? [11]
The atmosphere of the Earth primarily get heated due to which of the following?. Radiation is the process by which most energy is transferred through space from the sun to the earth
We can simply say that the radiation from Sun comes to earth in the form of smaller waves and earth being cooler body, gives off energy in the form of long-wave. This Long-Wave Radiation from the earth’s surfaces heats the lower layers of the atmosphere
What is the main mechanism that heats air in the atmosphere? [12]
This is pretty much all based on Atmospheric Heating and I assume you mean the atmosphere that surrounds you, rather than at any great height. I am concentrating on ground heat levels up to 500 m.
Higher frequency radiation has more energy than lower frequency radiation. Most of the sun’s radiant energy is concentrated in the visible and near-visible portions of the spectrum
It should be noted that, because of the proportion of sea to land on Earth, about 71% of the radiation from the sun falls on water. The specific heat capacity of seawater at $0^{\circ}$C is 3985 J kg$^{−1}$ $K^{−1}$, but because of currents and differences in sea levels, it may be difficult to estimate the true heat transfer by convection and consumption, to the air mass above the sea water.
Parts of the Atmosphere [13]
We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions.

Energy from the Sun that makes its way to Earth can have trouble finding its way back out to space. The greenhouse effect causes some of this energy to be waylaid in the atmosphere, absorbed and released by greenhouse gases.
However, Earth’s greenhouse effect is getting stronger as we add greenhouse gases to the atmosphere. Solar energy absorbed at Earth’s surface is radiated back into the atmosphere as heat
Why do greenhouse gases absorb heat? Greenhouse gases are more complex than other gas molecules in the atmosphere, with a structure that can absorb heat. They radiate the heat back to the Earth’s surface, to another greenhouse gas molecule, or out to space.
The Sun’s impact on the Earth [18]
Solar radiation that is not absorbed or reflected by the atmosphere (for example by clouds) reaches the surface of the Earth. The Earth absorbs most of the energy reaching its surface, a small fraction is reflected
The Earth radiates energy at wavelengths much longer than the Sun because it is colder. Part of this longwave radiation is absorbed by greenhouse gases which then radiate energy into all directions, including downwards and thereby trapping heat in the atmosphere.
This effect is enhanced by increasing greenhouse gas concentrations in the atmosphere due to emissions by human activities such as burning fossil fuels. The main long-lived greenhouse gases are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O)
How Is The Atmosphere Heated: Conduction, Radiation & Others – Class 9 [19]
The Sun is the main source of energy for heating the surface of the Earth. Sun is constantly radiating heat energy into space which is known as Solar radiation
The Earth�s surface is solid absorbs the incoming solar radiation. The air, resting over the surface of the Earth is heated by contact and other methods such as Conduction, Convection, Radiation, and Advection.
Let us see some methods through which Earth’s atmosphere is heated.. When two bodies having unequal temperatures come in contact with one another, the heat energy flows from the hotter body to the cooler body
Atmosphere of Earth [20]
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth’s gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth creates pressure, absorbs most meteoroids and ultraviolet solar radiation, warms the surface through heat retention (greenhouse effect), allowing life and liquid water to exist on the Earth’s surface, and reduces temperature extremes between day and night (the diurnal temperature variation).
Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in Earth’s troposphere.[citation needed]
The atmosphere changed significantly over time, affected by many factors such as volcanism, life, and weathering. Recently, human activity has also contributed to atmospheric changes, such as global warming, ozone depletion and acid deposition.
