Hurricanes Hurricanes, also known as tropical cyclones, are low pressure storm systems that form on open water and feed on heat released when moist air rises. Hurricanes are recognized on radar by their distinct pin wheel shape. When hurricanes begin to take shape they are called a tropical storm. The word “tropical” is used because most of these storms are formed by the very warm water of the tropics. Hurricanes need the ocean’s water temperature to be about 80 degrees to a depth of about 150 feet.
This was the most shocking fact that Sandy produced, usually when a storm makes it up to the Northern mid-Atlantic latitude, it is always way out to sea, but Sandy did otherwise. This factor was ultimately the one which caused all the damage and devastation for the habitants of N.Y if it wasn’t for the high pressure, the hurricane would have carried North rather than the quick turn forcing Sandy onto landfall. The geography of N.Y also made it more susceptible to storm surges. The long and narrow shape of the Long Island Sound helped to channel the waves in the 12 foot storm surge, making it even bigger. Additionally, areas such as Battery Park were built from landfill and therefore are low-lying areas and also flat.
The southern part of the USA is where a lot of tornadoes occur , to be precise more that 1,200 tornadoes and most of these are in the southern parts which mainly experience many of either F4 or F5 tornadoes annually . Tornadoes are a weather phenomenon that occur regularly throughout the US. They are caused by very low pressure systems that form during storm events. Signs of Tornadoes include unusual amounts of heavy rain and hail , A large, dark, low-lying cloud (particularly if rotating) and Dark, often greenish sky. These indicate the awareness of shelter and too be ready to take cover if needed.
They are both convection storms, which means rising air causes low pressure and, in turn, makes air rush in from surrounding areas to create very strong winds. However, the area that each storm covers differs drastically. A hurricane can cover up to 600 square miles while blizzards are limited to much smaller areas. To compare and contrast hurricanes and blizzards, the main points of interest are how these natural phenomena are formed, and the destruction associated with them.
The hurricane continued to strengthen, and Carol reached an initial peak intensity of 105 mph (170 km/h) late on August 27. By that time, it was a small hurricane, and the radius of maximum winds was smaller than normal for its latitude and central pressure. After maintaining peak intensity for 30 hours and moving a distance of about 75 miles (120 km), Carol weakened slightly off the coast of
It originally formed off the Bahamas, on August 23rd, as a Tropical Depression and strengthened to a Category 1 storm once it made landfall in Florida on August 25th. The warm ocean water, moist atmosphere and lack of wind shear that Katrina passed through allowed it to strengthen to a Category 3 storm by August 27th. That day, the Mayor of New Orleans to issue a voluntary evacuation, which he upgraded to mandatory on August 28th, only 19 hours before Katrina
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.
This is not far, compared to some of the world’s large oceans, but the size of the waves attacking the coast is increased by four other factors. One is the currents or swell, which circulate around the UK from the Atlantic and into the North Sea. The Atlantic fetch is 5000 km or more, and its currents add energy to waves in the North Sea. Therefore, there are often powerful destructive waves along the coastline, eroding the cliffs. The second point is the low pressure weather systems passing over the North Sea are often intense, and locally produce very strong winds and waves.
Tornadoes Purpose: To inform the audience about tornadoes. Introduction Attention Getter: What can hurdle automobiles through the air, rip ordinary homes to shreds, and travel at speeds over 60 mph? Topic Orientation: Topical Credibility: I researched the topic of tornadoes, and it’s most common to happen in parts of Texas, Oklahoma, Nebraska, eastern Colorado and western Iowa can also be referred as Tornado Alleys because of the warm and humid weather. Relevance: Well, tornadoes continue as they always have to tear out wide areas of human made structures, automobiles, or even entire small cities in Tornado Alley. Credibility: I researched the topic of tornadoes and the most common in the state of Illinois, rather than any
