Meteorology, or the science of the atmosphere, first was founded during Aristotle’s time. It was he who created the word “Meteorology” in his treatise entitled Meteorologica. Meteorology is not just the science of the atmosphere; it also includes the studies of physics and geography. When someone says they are studying meteorology, they are specifically referring to the science of the atmosphere and it’s “weather”.
“Weather”, as we know it, is the condition of the air at a particular place and time. Weather occurs in the lowest 12 miles of the atmosphere, also known as the troposphere. The upper troposphere contains high speed winds called the jet stream. Major factors which create weather are heat, pressure, wind and moisture. Another significant factor is the Earth’s geography, as it is comprised of many different average temperatures, humidity levels, and atmospheric conditions.
The Earth is encompassed by a gaseous shell: the atmosphere. Our atmosphere consists of five layers, called the troposphere, stratosphere, mesosphere, thermosphere and the exosphere. The combination of gases in the atmosphere is relatively stable. The first 99% consists of Nitrogen and Oxygen, while the last percent is a mix of more than nine other gases, such as carbon dioxide, hydrogen, and ozone. All of these gases contain similar characteristics of extreme mobility, compressibility, and capacity for expansion.
The air in the atmosphere always contains water vapor. Water vapor is an invisible gas, but it has a pronounced effect upon the weather. Vapor is contributed to the air by means of evaporation of water surfaces, soil, and living tissues. This is called atmospheric moisture, and it exists in all three stages; solid, liquid, and ...

- Despite increased literature on factors that influence management decisions, there are varying views as to which variables are critical to understanding farmer adoption. As a result, potential influencing factors can be categorized as either a characteristic or a cognition. Here the defining difference between the two categories is that cognition variables explore thought whereas characteristic variables do not. To further elaborate, previous research evaluating characteristic variables often explore traits exhibited by communities, farms, and farmers.... [tags: Global warming, Weather, Agriculture, Climate]

- 3.2 Modelling Aapproaches Climate change impact would depend upon complex interactions of climatic and biological factors with technological and socio-economical changes that are difficult to predict. Quantitative (modelling) approaches, which allows investigation of multiple scenarios and interactions simultaneously, will thus become more important for impact assessment (Coakley and Scherm, 1996). Sutherst et al. (1996) have given a framework for such model-based assessment of climate change impacts.... [tags: Climate change, Global warming, Weather, Climate]

- ... This stage called the dissipating stage. Because the air sink so the ground will have a lot of downward force wind called wind shear or microburst. These will produce very bad influence on airplane if the airplane want to landing or the airplane altitude is low because of the very rapidly downward force, it will make the airplane crashed on the ground easily. Sometimes because of the winds it will blow the thunderstorm and it will produce the lateral clouds out of the thunderstorm at the top of it, this clouds usually produce the hail so when the airplane found a thunderstorm it's not wise to cross under the thunderstorm clouds....

- In the New England area, the weather is very unpredictable due to the following reasons. New England sits right in the middle of the Jet Stream, a weather pattern that remains fairly consistent as it guides the weather for the entire United States. To the north of the Jet Stream, you have very cold Arctic air, and to the south of it, you have the warm moist Gulf air. These two factors help to create a very unstable atmosphere that can change the forecast of the weather at anytime. Many New England states lie along bodies of water....
