Within the Loop Current there is warm water that extends fairly deeper than the water surrounding it. Hurricanes usually churn up slightly cooler water allowing for some weakening of the storm; however a hurricane moving over the Loop Current churns up warmer water that extends deeper into the ocean. Camille's extraordinary strength could be blamed in part due to the assumption that it tracked directly up the axis of the Loop Current. After landfall, Camille dropped torrential rains on the southern states with anywhere from 2 to 11 inches of rain. Camille eventually strengthened somewhat as it moved more inland bringing major destruction to the state of Virginia with damage to property and life.
The associated air masses of storms within the British Isles are Polar maritime and Tropical maritime. As these two bodies of air move towards each other the warmer, less dense air from the south rises above the colder, dense air from the north. Circulations of low pressure then develop at points where the air is rising vigorously, this then coincides with waves in the polar front and jet stream. As a consequence there is much unsettled weather including heavy rain, strong winds and a variety of stormy cumulus clouds form; all of which can have devastating impacts socio-economically for an area as well as on the environment. The storm of 1987 occurred on the 15th and 16th of October due to a depression forming within the Bay of Biscay and had disastrous effects on the south and south-east of the UK.
Each event normally lasts 9-12 months they often starts in spring reaches its strongest point between December and January and appears to end around may of the next year. It frequently brings record rainfall to Peru, Chile and Ecuador. Southern Australia is often hit by drought and it also sees an increase in its temperatures. South east Australia heats up and because it is already dry due to drought there is a massive increase in the chance of bush fires. The other effects on Southern Australia are; lower rainfall, fewer cyclones, late and weak tropical monsoon and lower
[1] By the morning of October 15, the wave began to regain convection and eventually spawned a new area of low pressure roughly 475 mi (765 km) south-southwest of Puerto Ángel, Mexico. [2] By the afternoon, the NHC reported that the system had become increasingly organized and was likely to develop into a tropical depression later that day. [3] Around 11:00 am PDT (1800 UTC), the NHC declared that the low had developed into a tropical depression, the 20th of the 2009 Pacific hurricane season. [1][4] The storm featured well-developed outflow in all directions. Environmental conditions consisting of low wind shear, high moisture content and above average sea surface temperatures in the path of the system were exceptionally favorable for rapid development.
It moved to the north-northwest and intensified into a tropical storm just six hours after forming. Receiving the name Carol, the storm gradually turned to the north, and strengthened under generally favorable conditions.On August 26, the Hurricane Hunters reported an eye, 23 miles (37 km) in diameter despite Carol being a tropical storm. [3] The next day, Carol strengthened to attain hurricane status while located about 345 miles (545 km) east of Cape Canaveral, Florida. With a large anticyclone persisting across the southeastern United States,[4] the motion of Carol turned to a northwest drift. The hurricane continued to strengthen, and Carol reached an initial peak intensity of 105 mph (170 km/h) late on August 27.
The position of the UK makes storm events an inevitable part of our climate. Located at latitude of 52 to 56 degrees north of the equator, low-pressure systems frequently dominate our weather as cold air from the poles meet warm moist air from the equator. In total, five different air masses compete for control of our weather creating turbulent and unstable air that results in storms. A storm can be defined as ‘a rainfall and wind event that produces more than 0.1 inches of precipitation and which is separated from the previous storm event by at least 72 hours of dry weather’. This essay will firstly discuss the extent to which the impacts of storms in the UK, such as ‘The Great Storm’ of October 1987 in Southern England and the recent St Jude’s storm in October 2013, are the result of physical and human influences, and then evaluate the effectiveness the responses to these storms.
Ecological Footprint Bobby Chaiton Westfield State College Physical Geography Section 001 Carston Braun November 17, 2013 1. Describe the general time sequence between 24 and 30 August 2005 in terms of central air pressure and sustained wind-speed changes The wind speed changes when there is a difference in air pressure because of a function called the pressure gradient force. Simply put, the larger the difference in air pressure between two areas, the faster the air moves from the higher pressure to the lower pressure, just like a ball rolls down a steep hill faster than a more gently sloped one. As the central pressure of a hurricane increases, it causes the overall difference in pressure from the inside to the outside to become less, and thus the wind speed decreases in response
This condition made the soil to be more prone to the heavy winds, which blew the loose topsoil in what was described as the black blizzards. The effect was the blockage of the sun and the piling of dirt in drifts. The condition forced a mass migration of farmers and ranchers who left the region for California and other parts of the world (West, 2011). Causes of the Dust Bowl The problem leading to the events of the dust bowl began during the world war one. The war had led to increase in the price of wheat.
While one might ask how water erosion can be so prevalent in the desert, it is important to note that like many Australian deserts, the area receives a surprisingly high amount of rain, about 200-250 millimeters a year. ("Ayers Rock Facts," 2009) It is believed that the mountain chains that once included Ayers Rock were as large as the surrounding peaks. Now, there is just one remaining piece of this long lost chain. Wind and water took an enormous toll on the surface of the area. When one considers other major mountain chains, and is informed that they were once much larger, it is hard to grasp the concept due to the fact that the mountains still exist, and are fairly large in their current state.
