I believe the bottom layer of clouds (condensation) and the layer that forms the “anvil” in thunder clouds (freezing) are powerful IR radiation sources and glow quite brightly. In addition all of the electrical energy that the liquid crystal layer creates is rapidly released in ENORMOUS amounts in the form of lightning visible light. Radiation trapping Greenhouse effect. Condensation and Cloud Formation Cumulus clouds Cumulonibus clouds Cirrus clouds Stratus clouds. Chemistry of the atmosphere. Historic evidence of sulfuric acid emission in Greenland The Physics of Climate Author. The relationship between clouds and the surface radiative fluxes over the Arctic Ocean are explored by conducting a series of modelling experiments using a one-dimensional thermodynamic sea ice model. The sensitivity of radiative flux to perturbations in cloud fraction and cloud optical depth are determined. These experiments illustrate the substantial effect that clouds have on the state of Cited by:

The study of clouds, where they occur, and their characteristics, plays a key role in the understanding of climate change. Low, thick clouds reflect solar radiation and cool the Earth's surface. High, thin clouds transmit incoming solar radiation and also trap some of the outgoing infrared radiation emitted by the Earth, warming the : Steve Graham.
Two aircraft, flying parallel courses made simultaneous measurements both of cloud radiation characteristics, and of the meteorological parameters of the atmosphere and clouds. The processed data was studied to determine regularities in the variability of spectral reflection, transmission, and absorption of short wave radiation by stratus : K.
Kondratyev. A.L. Rangno (Retiree), in Encyclopedia of Atmospheric Sciences (Second Edition), Low Stratiform Clouds. Stratocumulus and stratus clouds (Figures 14 respectively) are low-based (below 2 km AGL), shallow ‘stratiform’ are almost always less than 1 km thick.
They are composed of droplets unless the cloud top is cooler than about −5 to −10 °C in which case ice. Natural infrared.
Sunlight, at an effective temperature of kelvins ( °C, °F), is composed of near-thermal-spectrum radiation that is slightly more than half infrared. At zenith, sunlight provides an irradiance of just over 1 kilowatt per square meter at sea level. Of this energy, watts is infrared radiation, watts is visible light, and 32 watts is ultraviolet radiation.
This chapter mainly focuses on advection Stratus/fog and Radiation Fog. Favoured synoptic environment for St/fog. Fog (or low Stratus) is formed, when moist air near ground level starts to condensate.
This condensation can be produced in the atmosphere by three mechanisms: By ascent and resultant cooling of an air parcel. By radiative heat loss.
Cloud droplets tend to scatter light efficiently, so that the intensity of the solar radiation decreases with depth into the gases. As a result, the cloud base can vary from a very light to very-dark-grey depending on the cloud's thickness and how much light is being reflected or transmitted back to the observer.

BAUM3 1Department of Atmospheric Sciences, Texas A&M University, College Station, TXUSA. Stratus clouds reflect more of uv radiation, the reason being two fold.
Uv radiation increases with increasing altitude and decreasing cloud cover. As you probably know Cumulus clouds, being low-stage clouds, are generally less than 2, metres. In the OSTI Collections: Clouds, Sunlight, and Radiant Heat - The sun radiates electromagnetic waves of every frequency into the space around it—much of it visible light, but also the higher frequencies of ultraviolet light, x-rays, and gamma rays, as well as the lower frequencies of infrared light, microwaves, and radio waves.
A small portion of all this radiation is intercepted by the earth. Water and atmosphere book. STUDY. PLAY. Terms in this set () Condensation. Many objects other than the sun radiant energy as light and heat. Electromagnetic radiation. Energy from the sun.
This energy travels in waves. Convection. Stratus clouds form and flat layers. Low, dark stratus clouds can block out the sun and produce a steady. Stratus clouds are low-level clouds close to the ground, so at times, stratus clouds appear fog-like and are even called 'high fog.' This is also associated with the feeling of dampness on the ground.
Some clouds form due to the heating of the Earth's surface. First, the Sun heats the ground, which then heats the air. This warm air is lighter and less dense than the surrounding air, so it begins to rise. When this air rises, it expands because of the lower pressures that exists at higher levels in the e air expands because of a drop in pressure, it also gets cooler.
That’s why you have to be careful how much x-ray radiation or UV rays you get, or you’ll get radiation sickness or a sunburn.
If the wavelength is longer, then that photon will have less energy – that’s why it’s not dangerous to stand in the way of microwaves, or cell phones, or radio or television broadcasts.
wispy, feathery clouds made mostly of ice crystals that form at high levels. a form of energy that has wavelengths longer than red light; not visible, but can be felt as heat.
Wordly Wise Book 6 Lesson 1 25 Terms. ms_reardon TEACHER. Worldly Wise Book 6 Lesson 2 32 Terms. Stratus clouds are a type of low-level cloud, occurring below 6, feet. They are characterized by uniform layers of grayish clouds.
Stratus cloud layers are generally thin but cover the entire sky, known as overcast. Stratus clouds are formed by weak, gentle upward air currents that lift large layers of air high enough to produce condensation.
High-level clouds: High-level clouds occur above ab feet and are given the prefix "cirro-". Due to cold tropospheric temperatures at these levels, the clouds primarily are composed of ice crystals, and often appear thin, streaky, and white (although a low sun angle, e.g., near sunset, can create an array of color on the clouds).
The three main types of high clouds are cirrus. Most clouds can be described by mixing and matching the terms cirrus, cumulus, stratus, and nimbus.
For example, there are cirrocumulus clouds which are vertically developing (and blotchy) clouds way high up in the atmosphere. Cirrostratus clouds are thin, wispy sheet clouds. What's cool about these clouds is that they can cause a halo-like. Tsay and Jayaweera ’s () analysis of the large-scale processes responsible for the formation of Arctic stratus clouds suggests that the layered structure may be a result of several simultaneous large-scale processes contributing to cloud formation.
In many respects the dynamics of layered Arctic stratus clouds appears to resemble the dynamics of weakly unstable stratocumuli observed. Clouds with Extensive Vertical Development: Cumulonimbus; A further classification is the prefix “nimbo” or suffix “nimbus,” which means raincloud.
Cumulus clouds are formed by vertical currents. They are billowy in appearance. Stratus clouds are formed by the cooling of a stable layer of air. They are flat and have a sheet-like appearance. The image gallery below contains many different clouds types.
The clouds are labelled and described in their figure captions. Stratus clouds over Diamond Head. Stratus clouds are a low level cloud type, composed of liquid droplets. They form in an atmosphere that is.
Bouncing around from cloud to cloud, and down to Earth, sunlight's warmth is both enhanced and blocked by clouds. Atmospheric scientists. Stratus clouds are part of the Low Cloud group.
They are gray and can cover most or all of the sky (like a big blanket). They are gray and can cover most or all of the sky (like a big blanket). Stratus clouds sometimes produce light mist or drizzle. This chapter mainly focuses on advection Stratus/fog and Radiation Fog.
Favoured synoptic environment for St/Fog. Fog (or low Stratus) is formed, when moist air near ground level starts to condensate.
This condensation can be produced in the atmosphere by three mechanisms: By ascent and resultant cooling of an air parcel. By radiative heat loss. Clouds, radiation and sun cream. Posted on 24 UV, while only accounting for a few percent of the light emitted from the Sun, contains the most energy and is the most damaging to our skin.
After an 8 minute journey from the Sun, the first line of defense incoming photons (small packets of light) will encounter is in the stratosphere, around. 19 12% of the land surface). Stratus clouds cover roughly 10% of the Earth’s surface (12% of the 20 ocean surface and 5% of the land).
Because stratus and stratocumulus clouds are so common and 21 because they strongly reflect incoming solar radiation these File Size: 1MB. The last variation on stratus clouds is the stratocumulus cloud. Occurring below meters, these clouds resemble little rows of cotton balls.
The coloring of these clouds can vary from gray to white depending on the sunlight angle. Precipitation is rare from this cloud; however, in the winter, if the top cools enough, some showers may occur. Cold objects emit less radiation than warmer object, with the relationship being about T^4, so a small change in temp makes a big difference.
Low clouds, on the other hand, tend to keep the earth cooler. They also absorb and reemit the earth's radiation, but because they are near the surface, they are close to the same temperature as the earth. The Earth's atmosphere shields life from deadly ultraviolet radiation from the sun and provides the planet with stable temperatures.
It contains a number of layers, the most well known of which are the troposphere, stratosphere, mesosphere and thermosphere. The vast majority of the weather occurs in the troposphere, but some clouds can appear.
Cirrus (cloud classification symbol: Ci) is a genus of atmospheric cloud generally characterized by thin, wispy strands, giving the type its name from the Latin word cirrus, meaning a ringlet or curling lock of hair.
This cloud can form at any altitude betw ft ( km; mi) ft (14 km; mi) above sea strands of cloud sometimes appear in tufts of a. 30 EARTH OBSERVATIONS FROM SPACE: THE FIRST 50 YEARS OF SCIENTIFIC ACHIEVEMENTS Annual ERBE Net Radiative Cloud Forcing NO DATA 0 10 20 30 40 W/m 2 Annual ISCCP C2 Inferred Stratus Cloud Amount NO DATA 0 10 20 30 40 50 60 70 80 Percent FIGURE â The top panel shows net cloud radiative forcing, annually averaged as.
There are not surfaces emitting radiation in the atmosphere. The recorded values correspond to a combination of radiation which is an average made by the instruments from a series of instantaneous measurements of globules of air moving up, stratus clouds, water vapor present in the atmosphere, and dust particles.
It play a important role in heat budget and cause cloud are devided into three layers. High Clouds; Middle Clouds; Low clouds; High Clouds . It usually found in the altitude of 6 to 12 km from the earth family clouds composed of mainly ice crystals because at greater heights amount of moisture is less and dew point is achieved at low temperatures in supersaturated situation.
the sky covered by clouds), altitude, thickness, and the size of cloud particles—all of which affect the amount of radiation transmitted, reflected, or absorbed by clouds. CLOUDS AND CLIMATE CHANGE Studying clouds is a top priority among many atmos pheric scientists because clouds are one of the great.
radiative models of Arctic stratus clouds have achieved considerable success in predicting the angular distribution of radiance by assuming that clouds have plane-parallel geometry. Makshtas and Korsnes , for example, have reported that surface measurements of the angular and spectral redistribution of solar radiation are well.
Stratus Clouds "Stratus" is the Latin word for layer or blanket. Stratus clouds form a low layer that can cover the entire sky like a blanket, bringing generally gray and dull weather.
Stratus clouds may form only a few hundred feet above the ground. Over hills and mountains they can reach ground level when they may be termed fog. Conversely. Thus the typical instrument discriminating the IR radiation between 7 m will measure almost the entire IR radiative cooling or heating of low-level water : Graeme Stephens.
How do clouds affect radiation. Wiki User They reflect incoming radiation (thus cooling in the. daytime), while trapping outgoing infra-red (thus "warming" at night).
Satellite observations of Low Cloud Cover (LCC) reveal an 11 year signal that shows some correlation with cosmic radiation measurements. This has led some to conclude that cosmic rays cause cloud formation. However, LCC also correlates with other indices of solar activity such as Total Solar Irradiance and sunspot numbers.
Can one determine how much cosmic radiation contributes to cloud formation. On cloudless nights the air temperature plummets; clouds act as insulators—sky blankets, if you will—to prevent heat loss from the earth and keep Jack Frost at bay.
Perhaps clouds are indeed the Earth’s thermostat. [Chapter-break] Most dramatic of all the clouds are cumulonimbus: the riders of the storm. Numerical simulation of radiation fog and stratus clouds formation with account for interaction among dynamic, radiative and microphysical processes.
Proc. 6th Cited by: Researchers have discovered the existence of high-altitude "radiation clouds" that can expose airplane passengers to high levels of radiation.
These clouds were discovered as part of .They can block *some* of it. But under partly cloudy conditions, they can sometimes exacerbate it.
> Clouds usually block UV rays, particularly UV-B; on a really overcast day they can keep out 70 to 90 percent of the UV-B coming in. > Maddeningly.
