A Study of the Prime Causes and Disastrous Effects of Hurricanes Causes. There are two main factors that are responsible for causing hurricane storms, viz. warm water and moist, warm air. This is the reason why they begin in tropical regions. They occur when the moist, warm air from the surface of the ocean rises and meets the cooler air.

- Hurricanes produce storm surges, tornadoes, and often the most deadly of all -- inland flooding. While storm surge is always a potential threat, more people have died from inland flooding in the last 30 years. Intense rainfall is not directly related to the wind speed of tropical cyclones.

How Do Hurricanes Form? Storm surges are frequently the most devastating element of a hurricane. As a hurricanes winds spiral around and around the storm, they push water into a mound at the storms center. This mound of water becomes dangerous when the storm reaches land because it causes flooding along the coast.

Tropical cyclone The majority (83%) of tropical cyclone damage is caused by severe hurricanes, category 3 or greater. However, category 3 or greater hurricanes only account for about one-fifth of cyclones that make landfall every year.

'what is the effect of sea temperature on hurricane'? The effects of hurricanes listed here are both directly and indirectly caused by it. Firstly, a hurricane is made up of a low-pressure core with rain and wind clouds surroun … ding it. The low-pressure core may bring in lots of water from the sea or ocean, called a storm surge.

- Hurricanes like Katrina are the most powerful storms in nature. They begin when a group of storms comes together over warm waters in the ocean along the equator. All summer long, these areas absorb heat from the sun. By late summer, the higher water temperatures allow storms to strengthen and grow.

Warmer Seas Creating Stronger Hurricanes, Study Confirms A rise in the world's sea surface temperatures was the primary contributor to the formation of stronger hurricanes since 1970, a new study reports.

What causes tornadoes? As the air in a vortex is brought closer to the axis of its rotation, the spin increases. At the most basic level, this is what causes all intense atmospheric vortices: tornadoes, hurricanes, dust devils, etc.

- Another cause is the flooding resulting from the coastal storm surge of the ocean and the torrential rains, both of which accompany the storm. The Saffir-Simpson scale is the standard scale for rating the severity of a hurricane as measured by the damage it causes.

Hurricanes Facts A hurricane can drop more than 2.4 trillion gallons of water (as rain) in one day. A hurricane can also produce tornadoes, and flooding of coastal regions. The center of the hurricane is called the eye of the storm. It is usually calm. The size of the eye can range from 2 miles to 200 miles wide.

Hurricane Preparedness - Hazards A better understanding of tropical cyclones and hurricane hazards will help to make a more informed decision on your risk and what actions to take. The major hazards associated with hurricanes are: storm surge and storm tide; heavy rainfall and inland flooding; high winds; rip currents; tornadoes

Causes and Effects of Hurricane Katrina “Hurricane Katrina was one of the strongest storms to impact the coast of the United States during the last 100 years.” (“Hurricane Katrina” from NOAA) Hurricanes all start in tropical waters because they can only start in warm waters.

- 1 High Winds--This is the most important effect of a hurricane since it determines how powerful the storm is, and how much storm surge and damage it can cause. Winds in a hurricane can reach up to 200 mph.  Tornadoes--This is probably the least thought of effect of a hurricane, but they do occur. Tornadoes occur in a hurricane as a result of the tremendous energy and instability created when a hurricane makes landfall. Most tornadoes that occur in hurricanes are only minimal in strength.

- Slower and larger but weaker hurricanes (e.g., Category 3 storms such as Katrina) cause much higher storm surge and flooding (even to inland areas) when compared to faster and small but more intense hurricanes (e.g., Hurricane Charley in 2004).

- Hurricanes carry a lot of rains with it and even after the hurricane has subsided, it may continue to rain. This causes a lot of floods and brings about other types of destructive results. Houses, cars, farms, and many other structures are blown away by the powerful winds that come with hurricanes. Impact on the economic Anytime there is a disaster caused by a natural phenomenon like hurricanes, floods and fires, there is extensive damage to property.

Hurricanes Hurricanes spin around a low-pressure center known as the “eye.” Sinking air makes this 20- to 30-mile-wide (32- to 48-kilometer-wide) area notoriously calm. But the eye is surrounded by a circular “eye wall” that hosts the storm’s strongest winds and rain. These storms bring destruction ashore in many different ways.When a hurricane makes landfall it often produces a devastating storm surge that can reach 20 feet (6 meters) high and extend nearly 100 miles (161 kilometers). Ninety percent of all hurricane deaths result from storm surges.A hurricane’s high winds are also destructive and may spawn tornadoes.urricanes spin around a low-pressure center known as the “eye.” Sinking air makes this 20- to 30-mile-wide (32- to 48-kilometer-wide) area notoriously calm.

What Causes Hurricanes? The natural engine that is a hurricane is fueled by warm, moist air. The storms move heat from the ocean surface high into Earth’s atmosphere. They can travel thousands of miles from the tropics toward the Earth’s poles.

Hurricanes form over tropical oceans, where warm water and air interact to create these storms. Hurricanes form over tropical oceans, where warm water and air interact to create these storms. Hurricane Sandy as seen from NOAA's GOES-13 satellite on October 28, 2012. Image courtesy of NOAA/NASA.

Hurricanes and Climate Change But like many questions in science, this isn't a case of straightforward cause and effect. Many scientists accept the broad premise that a hotter climate likely contributes to some increase in hurricane strength, that this process is already underway, and that it will intensify.

- There are two ways that hurricanes produce flooding. In coastal areas the winds of a hurricane push seawater onto land. This is called the storm surge.

Hurricane Preparedness - Hazards Hurricanes also produce tornadoes, which add to the hurricane's destructive power. These tornadoes most often occur in thunderstorms embedded in rain bands well away from the center of the hurricane. However, they can also occur near the eyewall.

- Storm Surge - The strong winds of a hurricane can push water up and onto land. This water can cause major flooding and damage to homes, cars, and boats. Heavy Rains - Hurricanes can cause heavy rains that flood places inland and away from the center of the storm. Some hurricanes have produced over 20 of rain.

What is Government? - Definition, Role & Functions While all of these definitions help us grasp the meaning of the word 'government,' they provide a lot to remember, so let's summarize. Government, whether we refer to the system or institutions in operation, the group of people in charge, or the process in use, is the authority that sets rules for a society, helps its members relate to one another and to others, and keeps it running smoothly, securely, and peacefully.

Three Common Types of Flood Explained Storm surge — produced when high winds from hurricanes and other storms push water onshore — is the leading cause of coastal flooding and often the greatest threat associated with a tropical storm. In this type of flood, water overwhelms low-lying land and often causes devastating loss of life and property.

Hurricanes and Climate Change Here's a look at what we know, and don't know, about global warming and hurricanes. A view of Hurricane Igor's eye from the International Space Station. Enlarge Photo credit: Courtesy NASA. Hurricanes are, in effect, giant heat engines. They transfer latent heat energy from the ocean to the atmosphere, transforming some of it into mechanical energy in the process: the maelstrom of hurricane-force winds and giant waves.

"Definition of ""Largest Hurricane""" The largest loss of life from a hurricane is often caused by storm surge and flooding rather than the winds. Do not underestimate a lower category hurricane! None of the top five deadliest hurricanes in United States history were a Category 5 hurricane at landfall.
