The global pattern of atmospheric heating and circulation is the high precipitation in the tropics which is produced by high rates of evaporation and subsequent concentration of water vapor in ascending air masses. Energy from the sun heats up earth but unfortunately it doesn’t distribute it evenly across the surface of the earth. The tropics receive more heat radiation than they produce the arctic or the polar region produce more radiation than they receive. The clouds formed in this way produce the heavy precipitation associated with the tropics. The mechanisms of high precipitation at temperate latitudes is produced when warm, moisture-bearing subtropical air meets cold polar air, which forces condensation of the water vapor in the subtropical air mass. Precipitation is mainly to do with the temperature of the air. Higher the airs temperature the more moisture it can hold, and vice-versa. Since the tropics are warmer the air holds more moisture and won't lose it until it interacts with colder air, which is usually at mountains as cold air is forced up into the hot air by the ...
On Friday, December 7, the last monkey was finally put down. After this the decon team arrives. They seal off the building and heat these special crystals that kill everything that is living. Also, the team learns that Milton Frantig, the employee who had fallen ill, had recovered from what seemed to be the flu.
1) the experiment with the pop can is that the can will crush because of a drastic change in temperature.
The Earth’s crust and upper mantle is called the lithosphere. Plate tectonics is a theory describing the movement of the 7 major tectonic plates that make up the lithosphere. Every year tectonic plates only move a maximum distance of 100mm, when tectonic plates meet they can slide past each other or under each other resulting in earthquakes, volcanic activity, creation of mountain and islands, as well as oceanic trench formations. There are many theories on how tectonic plates move including convection. Convection is the heat waves that rise from the Earth’s molten core and influence plate activities. Convection can be attributed to volcanic activity, the expansion of the seafloor, as well as earthquakes.
The rising of temperatures is caused by factors called climate forcing or “forcing mechanisms”. This includes processes such as variations in solar radiation, variations in the Earth’s orbit, mountain-building and continental drift, and changes in greenhouse gas concentration. Solar radiation gets trapped by gases, which are created on earth, in the atmosphere. The radiation comes from the sun towards earth and bounces off the earth’s surface. However much of the radiation gets trapped by the gases remaining behind which warms our planet instead of going back into space like previously. This is known as the greenhouse effect. Some of the major contributing gases are; water vapor, carbon dioxide, methane, and our ozone layer. According to sources at Real Climate, 36-85% of the greenhouse effect is due to water vapor (including clouds), followed by carbon dioxide at 9-26%, and last all the minor greenhouse gas absorbers at 7-8%. Humans contribute to the greenhouse effect by deforestation, land use changes, and burning fo...
As the temperature increases it increases evaporation, which makes its way to land and causes a higher amount of precipitation and winter weather. While the harsh storms come and go the evidence still shows temperature increasing as a whole, up about two degrees in the past thirty-five years (Source 8).
4) Oceanic circulation-Ocean currents have the potential to affect Earth’s climatic condition. This is because they have the capacity to carry a large amount of heat. Winds blowing over cooler currents become cold and the areas over which they blow have their temperature reduced. Similarly if winds blow over warmer currents, the wind picks up heat and areas over which the wind blows sees temperature increase. If winds blow over evaporating currents the pick up moisture and bring rain to the areas over which they blow.

The world’s climate is kept stable and suitable to live in, mainly by rainforests, in a number of ways. They are often known as ‘climate controllers’. They keep the planet cool, as they absorb much of the suns heat, instead of reflecting it back into the atmosphere.
First is a description of the greenhouse effect. The earth’s atmosphere has four layers, or zones, with each having distinct differences in temperature. The troposphere is the first layer surrounding the earth. Within this layer air is continually circulating and moving heat and moisture around the earth. The troposphere is denser than the other layers due to the fact that gravity keeps the majority of air molecules near the earth. This is about 75 percent of all the atmospheric mass. It is also the warmest layer (Cunningham & Cunningham, ...
Rain in reality is moisture condensed from the atmosphere that falls visibly in separate drops. To get rain, the water condensing in the clouds has to become heavy enough to fall to Earth. To become heavier, some will collide with other droplets and become larger, and others will grow as water condenses out the air directly into the droplet, and some will do so by both methods. Eventually, if the droplets keep growing, they will reach a mass where they can't stay floating in the cloud because they are too heavy and will start to fall as rain. Before it can rain, there must be moisture or humidity in the air. In order for there to be moisture in the air, water must evaporate. The best source for the air's moisture is the oceans and sometimes lakes. Air flows over these large bodies of water picking up moisture as it evaporates off the surface. The air then flows over the land and we feel it in the form of humidity. When air rises, such as up a mountain slope, or when encountering a cold front or warm front, the air cools and the moisture condenses into clouds and rain. Because of this, areas
Although when there is less moist air developing over the northern Indian ocean less clouds full of precipitation is moved to southern Australia and victoria greatly impacting the rainfall for the usual time periods over winter and spring.
August heat is one of those mystery stories that make the reader want to keep
Thompson et al. (2009) has noticed that the ice tops on the peak of Mount Kilimanjaro will disappear due to the rapid heating and warming up of the air. Lastly, these high air temperature patterns would lead to a loss of habitat to many of the animal species and also a lot of rainfall on the African continent which might not favour some countries as there can be floods. In conclusion, having looked at all these researches, the findings indicate that there has been an increasing pattern in air temperatures since the beginning of the twentieth century, however, some areas experienced hotter than normal temperatures, which was noticed by the Remote Sensing System and the University of Alabama in Huntsville (Collins, 2011).
Climate change is evidenced through shifts in the weather patterns such as winds, humidity and temperatures over certain durations. Natural climate changes occur less frequently and they are triggered by factors related geographical aspects as well as solar radiation. The earth’s movement on the orbit triggers changes in climate causing some areas to have higher temperatures than usual while others are significantly cold depending on the position of the earth on the orbit. The heat form the sun causes changes on the stratospheric ozone and it increases the amount of greenhouse gases. Heat from the oceanic crust also contributes to warming as a result of episodic hydrothermal venting (Liao & Sandeberg, 2012). Volcanic activity also causes a release of certain elements that may block the sun and also contribute to increase greenhouse gases in the atmosphere.
The atmosphere surrounds the Earth as a thin, about a 100 km thick layer and it consists of 78% N2(Nitrogen), 21% O2(Oxygen), 1% Ar(Argon) and 0.0.39%CO2(Carbon Dioxide). The atmosphere has a number of different layers and each of those layers have different properties. Changes in weather, clouds, rain and wind are formed in the lower atmosphere, 10 to 15 km thick layer known as Troposphere. Although troposphere is deeper in tropical regions, reaching up to 20 km, however in polar regions it can be as shallow as 7km during winter. Troposphere is 90 per cent of the total mass of the atmosphere, and nearly all of the water vapor and this is due to the processes of transpiration and evaporation. As the altitude in the troposphere increases, the temperature decreases by about 6.5 ° C per kilometer increase in altitude. The upper limit of the troposphere is the coldest and it ends at a point called “tropopause”, which is where the upper atmosphere, also known as “stratosphere” begins. The stratosphere, which extends about 50 km from where troposphere ends, is stratified in temperature and lower layers are cooler whilst temperature increases in the layers higher up. The reason why stratosphere is layered in temperature is because ozone (O3) there absorbs Ultraviolet C energy waves and high energy Ultraviolet B from the sun and its broken down in to diatomic oxygen(O2) and atomic oxygen(O). Therefore, The Stratospheric ozone layer protects the plants and animals of carcinogenic and lethal amounts of sun exposure. Although about 10% of the mass of the atmosphere is located in the stratosphere, the air is very thin. The upper region of the atmosphere is known as the Ionosphere and it begins at approximately 85km altitude and stretches ...
