Effects of Atmospheric Instability on the Anthrosphere :: Geology

EFFECTS OF atmospherical INSTABILITY ON THE ANTHROSPHERE INTRODUCTIONThe atmosphere rises to 500 km preceding(prenominal) Earths surface. The atmosphere is divided into four parts based on temperature shift in relation to change in altitude. The four parts atomic number 18 the Troposphere, Stratosphere, Mesosphere, and Thermosphere. This paper will be discussing inst ability in the Troposphere, the lowest level, since it is where the Earths die hard takes place. Tropospheric instability often times yields severe weather, such as tornadoes. A Tornado is a violently rotating column of manner in opposition with the ground and pendent from a cumulonimbus obliterate. A tornados fierce winds have the ability to severely impact the lives of humans by turning innocent unmoving objects into flying missiles, collapsing buildings, and even throwing people hundreds of yards. One researcher summarized tornadoes well when he said Tornadoes are one of the Worlds stro ngest forces, and they will not stop at anything that will get in their way(Elias Demakes). FORMATION OF SEVERE put upHOW Atmospheric instability is the result of air rising in a cloud that is warmer than its surroundings. The heat released by the condensation within the cloud allows the rising air to maintain its relative warmth in par to its surroundings. This is characteristic of a supercell, the strongest type of thunderstorm (Supercell). Supercells choke when the warm updraft moves through an overlying stable layer and continues upward into a zone of unruffled dry air. This process produces fierce vortex motions, a pre-requisite for tornadoes.WHERE Tornadoes can authorize anywhere as long as the conditions are favorable. However, the United States is array to more tornadoes than any other country. And within the United States, geographically, the western plains has the highest relative frequency of tornado go throughences. The western plains has so m any that it has become known as Tornado Valley. One reason that this area receives so ofttimes tornadic activity is because here, the warm, moist air from the Gulf of Mexico converges with the cool dry air from the north. This creates the unstable atmosphere necessary for the formation of a tornado.WHEN Tornadoes can occur on any day of the year at any hour. However, tornadoes occur most frequently in the spring.
