hapter 7 Questions Clouds to form in the atmosphere have to have water vapor present. This water vapor makes up a cloud. The water vapor in the atmosphere comes from evaporation or deposition. Also the temperature of the air is below the dew point. When the water is fully saturated, it starts to rise and the expansional cooling process begins. During the process of condensation, the aerosol particles act like a nuclei in the atmosphere, which began to grow, creating ice crystals that are big enough to produce a cloud. Examples of natural sources of nuclei could be wind erosion of soil, volcanic eruptions, sea spray, ocean organic compounds and even forest fires. Cloud condensation nuclei (CCN) helps assist the condensation of the water vapor process. When the process of condensation occurs, the nuclei which are particles of liquid that are found in the atmosphere, helps water vapor grow and condense turning into a cloud formation. Hygroscopic nuclei is derived from the cloud condensation nuclei process. It is very significant in cloud formation because it can pull together different types of water molecules in the atmosphere due to a …show more content…
The usually have a temperature of -13 degrees Fahrenheit (-25 degree Celsius) therefore ice crystals is what mostly makes up this type of cloud, which has a fibrous appearance. For middle clouds, they have altitudes between (6,600-16,000 ft) and a temperature range from 32 degrees Fahrenheit (0 degree Celsius) and -13 degrees Fahrenheit (-25 degree Celsius). These clouds can either have supercooled water molecules or they have a combination of both water droplets that are supercooled and ice crystals. For low clouds, can have an altitude up to (6,600 ft) and have a temperature of 23 degrees Fahrenheit (-5 degrees Celsius). They can appear as fog or stratocumulus clouds. Water droplets mainly make up these low clouds and
During June and July aerosol loading was comparatively higher at around 2-6 km height compared to the rest of the months. This possibly explains the high values of COF (figure 15 (b)) at higher altitudes in these two months due to convection processes that might have contributed to the formation of CCN (Jiang et al., 2007; Jiang et al., 2011). Excess rainfall events during 2013 ISMR, had resulted in heavy wash out of aerosols in the entire season which can be observed from low AOF values. The month of June witnessed an early onset of monsoon because of which there were more washouts of aerosols and September being the offset phase of the monsoon, witnessed high aerosol loading. July and August witnessed low AOF values, except that August had higher value of nearly 30% than that of June which had nearly 10-25% at 0.5-2 km altitude range The aerosol loading during June, July and August above the lower troposphere up to 4-6 km altitude might have contributed to cloud formation at higher altitudes which can be seen in the COF values of nearly 10-20%, 15-20% and 10-30% respectively at 12-17 km height range.
When I was reading Ona cloud rider I noticed that in one of the scenes they were good clouds and they were bad clouds, both sides different. So I went researching if they were different kinds of clouds. Yes they were different clouds, you can call them rain clouds or you can be more specific and call them high low or medium clouds. The groups are based on the height of the clouds kind of like some MLG tournaments how they referred some of their teams as A, D depending on what position they are in. My 2nd reason why this is real is look at some photographs at clouds, you can see tons of pictures about clouds and they are also some rarities of clouds like uncommon or rare clouds, an example
Nucleus - the central and most important part of an object, movement, or group, forming the basis for its activity and growth. When thinking about CDS, I have to think about the main person is at school and what immediately comes to mind is the head of school, Mr. Duncan. The reason I have chosen Mr. Duncan as the nucleus because he is the reason why we are expanding the school, he represents our school when he goes to conferences, talks more about how the school can improve.
These clouds can exist undisturbed for extended periods, as they are quite able to withstand their own gravity, due to the low density and magnetic field that protects it from drifting into open space, and are considered to be stable. If a nearby, external
Have you ever seen a condensation trail from a plane (mainly jet) that persists in the sky? Unless you are extremely high in the atmosphere, that is not normal. They are actually chemical trails from dumping chemicals across the
A molecular cloud is a giant condensation of dust and molecular gas. They are regions of relatively dense interstellar gas and dust with hydrogen molecules as well as carbon and silicate materials forming the primary constituents. Helium and small amounts of heavier elements are also found within the cloud. Molecular clouds are very cold and dark regions with typical temperatures of between 10 and 50 Kelvin. The mass of a typical
We know this can be induced because scientists have been experimenting with a practice called "cloud seeding" for decades.” Michelle Starr used this example of Logos to prove that increasing the amount of diesel exhaust fems increases cloud formation.
In theory, the scientist Phil Plait says " the clouds coming from jets they are really just a product of condensation of water vapor. In newscientists.com, 77 scientists report that the results were surprising, 98.7% of scientists say that there is no atmosphere programing.
Is the process of forcing clouds to rain. Cloud Seeding involves flying a plane over clouds and dispensing silver iodide into the clouds. The silver iodide mimics ice crystals and gives the moisture in the clouds something to cling to, the moisture has clung to the silver iodide and is now snow this then is heavy enough to fall out of the clouds. The snow then melts into water then we have rain. Cloud Seeding is a very good solution to droughts because it is very area effective. It costs more than other solutions but for the area it covers it is efficient.
Rain falls when clouds contain so much moisture that they can’t hold anymore and force it down to the ground. While all the moisture is still in the cloud, though, it acts as a sort of deflector for sunlight. Each individual drop of water that is in a cloud catch the sunlight, and therefore the solar radiation, and keep it from coming through to the earth. Clouds that are very bright have a lot of moisture in them that is catching the sunlight and deflecting it back.
First, tornados are formed by plenty of supercells. Actually, supercells are a huge cluster of thunderstorm clouds. In other words, heat rises up as it has a low vapor pressure and cold air drops down because of its high vapor pressure. (The National Severe Storms Laboratory) Because of this, the warm air in the end forms a vortex and forms a funnel cloud, also known as tornado.
The process begins when the sun starts to heats up the surface which creates warm air. The warm, less heavy air rises and converges with the cold less heavy air above. This process is known as wind shears. Wind shears are when two
The components that creates a thunderstorm includes moisture, instability and a lifting mechanism. These components are what determines the severity of a thunderstorm as well as an abundant of vertical wind shear. If the wind is weak in speed and direction, thunderstorms won’t reach hazardous weather.
When mountains, plains, and slopes have an upward breeze, it causes upslope fog. This fog can occur on the eastern side of the Rockies during the winter and spring (Ahrens, Samson 99).
The atmospheric parameters, including, aerosols, clouds, and precipitation, play very important role in our Earth’s climate system. The climate feedbacks influencing the global climate variability are directly or indirectly affected by aerosols, clouds, and precipitation, and thus, modulate the Earth’s radiation and surface energy balance. Therefore, global observations of aerosols, clouds, and precipitation are crucial not only to better understand the processes involved in the climate system but also to predict the future climate change.
