Tropical cyclones, therefore, form only over oceans with water temperatures of at least 80 deg F. After they have formed, such storms tend to intensify when passing over warmer water and weaken when passing over colder water. The rate of condensation heating resulting from the intense rainfall associated with hurricanes is about 100 billion kW. In one day, therefore, a hurricane produces 24 X 100 billion kW h, an amount of energy that lies within the range of the yearly consumption of power by many industrialized nations. The mature hurricane is characterized by an eye--a cloud-free circular region of relatively light winds in the center of the storm. The sinking motion in the eye, which causes the clearing, also produces adiabatic warming and drying.
Hurricanes Hurricanes summer is over and fall has arrived but many people to the south of us are observing another season hurricane season. According to the Montshire Museum of Science, hurricanes usually occur in the North Atlantic from June to November, with most of them in September. On average, between six to eight hurricanes form in the North Atlantic or North Pacific each year (Montshire), however, as many as 15 have occurred in the Atlantic in a single year. Hurricanes are powerful, whirling storms that measure several hundred miles in diameter. The winds near the center of a hurricane blow at speeds of 74 miles per hour or more (World Book, 400).
This scale measures hurricanes by their wind speeds. A category one hurricane has wind speeds of 74-95 mph, and will travel at a rate of 119-153 km/hr. A category two hurricane has wind speeds of 96-110 mph, and travels at a rate of 154-177nkm/hr. In addition, a category three hurricane has wind speeds of 111-129 mph, and will travel 178-208 km/hr. Next, and category four storm has 130-156 mph wind speeds, and travels 209-251 km/hr.
The storm surge is generally 4-5 feet above normal. Damage is mostly to trees and shrubbery, with no real building damage. Average wind speed for a category 1 is 74 to 95 mph with a minimum central pressure of 980 mb. Hurricane Sandy hits its first landfall on October 24th, near Kingston Jamaica, with winds of 80 mph. (Fast Facts) The second landfall hit Cuba as a Category 2 hurricane with 105 mph winds.
If the same tornado went through a similarly populated area in the United States with standard $150,000 to $200,000 houses, the damage would have been around 2.5 billion to 3.2 billion. In Bangladesh, due to the orbital movement of the earth the wind changes direction twice a year, once when the Tropic of Cancer starts moving towards the sun
The SEEALL Academy Joel Rakhamimov Class 601 May 30, 2014 A hurricane is a tropical storm exceeding 74 mph in wind speeds. It is a low-pressure system which forms when there is a warm & moist environment over the ocean. Hurricanes are named to easily identify them. The first hurricane of the year starts with the letter 'A', the second 'B', and continuing. Hurricanes are only classified as hurricanes when they have wind speeds of 74 mph or more.
Also I will inform about the major hurricanes that happened in the United States. A hurricane or a tropical cyclone is an intense, rotating oceanic weather system that possesses maximum sustained winds exceeding 119 km/hr (74 mph). It forms and intensifies over tropical oceanic regions. Hurricanes are generally smaller than storms in mid-latitudes, typically about 500 km (311 miles) in diameter. At the ocean’s surface, the air spirals inward in a counterclockwise direction.
This rule applies to all storms including typhoons. The categories are determined based on the wind speed and how large a space it covers. A category 1 hurricane has winds from 74-75mph and does not due much damage to buildings and houses; a... ... middle of paper ... ...October 12th 1979. In number 6 Typhoon Sally which hit Ponape on September 3rd 1964. In number 5 Typhoon Kit which did not reach landfall but was still extremely powerful and had winds at the exact speed as Typhoon Haiyan (195mph).
A tropical cyclone is rated by the “Saffir-Simpson Hurricane Wind Scale” in the Atlantic and Pacific Oceans. It’s name comes from the founders names: Herbert Saffir, and Robert Simpson. A Category 1 storm has winds between 74 and 95 miles per hour, and a storm surge of 4 to 5 feet. Shrubs, trees, and unanchored mobile homes are damaged. Low-lying coastal roads are usua... ... middle of paper ... ...inches wide, 17 inches tall, and 10 inches thick.
Irene produced record breaking rainfall across the mid Atlantic and northeastern United States. The highest rainfall recorded during Hurricane Irene's storm run was in Bayboro, North Carolina at about 15.7 inches of rain. At least half of the deaths that were caused by Irene in the United States were due to fresh water flooding from heavy rainfall. When passing through the northeastern United States tropical cyclones are restructured by the course of extratropical transition. This is caused by the contact with strong westerlies that are associated with a mid latitude trough and causes an enhance in storm forward motion, vertical wind shear, and vorticity.
