Causes of Natural Hazards Essay

Hurricanes need two ingredients to form: warm ocean water and wind. There are four stages of a hurricane, depending on the wind speed: tropical disturbance, tropical depression, tropical storm, and hurricane. They first begin as tropical disturbances near the equator, where the temperature of the ocean water is at least 80 degrees Fahrenheit and winds are blowing approximately 23 miles per hour or less across the ocean surface. The wind causes water to evaporate and rise, forming cumulonimbus clouds. As evaporation and condensation continue, these clouds become larger and higher. Winds pick up to between 23 and 38 miles per hour, where the storm has become a tropical depression. Warm air rises and leaves the area with lower air pressure. Areas with higher air pressure move into the low pressure area. Then this warm air rises and more surrounding air moves in to take its place. The system of clouds and wind grow, fed by ocean water evaporating. As the system spins in a circle, an eye forms that is of low pressure. Higher pressure air from above flows into the eye of the storm. When winds reach 39 miles per hour, the storm is called a tropical storm. When winds reach at least 74 miles per hour, the storm is considered a

Most hurricanes are formed over the Atlantic Ocean. The optimal weather conditions for a hurricane to form are warm, moist air as the fuel, warm ocean water and wind. Combining all of these factors makes for a strong, powerful hurricane. Hurricanes are formed when warm, moist, air moves over the water, the warm air rises being replaced by cooler air. The cooler air starts warming and rises. This cycle repeats and creates very large storm clouds to form. The wind makes the clouds spin into a large counter-clockwise pattern. As the wind speeds pick up, it makes the clouds spin faster and making it more dangerous.

Over the past few centuries, the natural disaster of hurricanes has had a huge impact on the land around us. It could cost millions, or even billions of dollars in repairing the damages done by hurricanes. These natural disasters can not only result in property damage but also many lives lost and injured victims. Hurricanes usually leave many without homes, forcing victims to find shelters or relocate to a different city or state for safety. A hurricane is a violent, tropical, cyclonic storm with sustained winds of at least 64 knots (74 miles per hour: 119 kilometers per hour) that are extremely large, powerful, and destructive. Hurricanes usually start to occur over large areas of warm water, such as the Atlantic Ocean. They generally form during the hotter months due to the fact that it gets energy from the heat off the water.

The Formation of Hurricanes Hurricanes begin as tropical storms over the warm moist waters of the Atlantic and Pacific Oceans near the equator. (Near the Philippines and the China Sea, hurricanes are called typhoons.) As the moisture evaporates it rises until enormous amounts of heated moist air are twisted high in the atmosphere. The winds begin to circle counterclockwise north of the equator or clockwise south of the equator. The relatively peaceful center of the hurricane is called the eye.

Hurricanes emerge from the tropics of the Atlantic Ocean close to the earth’s equator because it is attracted to warm water with a temperature of at least 80 degrees Fahrenheit (Today’s Science, October 2004). As the temperature increases, it changes the liquid water into water vapor that forms clouds of warm, moist air causing it rise.

First, hurricanes form in warm water. Therefore, states or places closest to the equator will most likely get hurricanes. In different places, it has different names, like a typhoon or a cyclone. Hot air rises making less hot air below. It makes clouds, then circulate to form a hurricane. On the scale, a category 5 hurricane can have winds up to 157mph, maybe even more.

As many know, hurricanes are considered to be among the most powerful forces in nature. A hurricane is a powerful storm system that produces intense winds and heavy rainfall. Hurricanes form over warm ocean water during warm months such as June, July, and August which is known as the

A hurricane is formed by warm and cool air mixing (Hurricane Katrina). The warm air rises which cause the cool air to fall (Hurricane Katrina). Once the warm air reaches the top, it cools, then

Hurricane Katrina is from a tropical wave and it hit the Bahamas in2005. It was the 11th tropical storm in the 2005 hurricane season. A hurricane is a violent wind and water storm that causes tons of damage and death. The fuel for hurricanes is water vapor. Hurricanes are formed by water vapor and hot air the reason for hurricanes is to cool down the ocean.

Leading up to a hurricane will start feeling warm and moist, allowing the air to become warm an humid, also allowing latent heat to spread. the next need is low pressure disturbance, also know as a tropical wave, to rise and make strong thunderstorms.if hurricanes try to form to close to the equator, it will not be strong enough to gather its self and rotate.

Hurricanes usually form over ocean areas near the Equator during summer months, since the ocean surface is at its warmest. The heat and moisture from the ocean provides the hurricane energy, and maintains it after its been formed. In this case, Hurricane Sandy travelled up north, growing colossal and relentlessly from the energy. However, if the supply of heat or moisture from the ocean is cut off, it will weaken the strength of the hurricane. Therefore, a hurricane is usually most destructive when it first moves over land. When a hurricane passes over land or cold ocean water, it loses its energy source of evaporating water and slowly dissipates.

Essentially, a hurricane is just a big storm. Hurricanes are formed when the moisture in the air evaporates and rises up until the heated moisture is twisted into the atmosphere. The cold and hot air will start “chasing” each other anti clockwise, and can reach speeds of 75 miles per hour.

Hurricanes form during the summer and early fall, ocean water vapor creates energy for warm, intense low pressure areas (“What causes hurricanes?” par.

Hurricanes start because of warm moist air of the atlantic and pacific ocean. When warm moist air and the ocean start to mix together it starts to make a hurricane. Hurricanes form close to the equator. lost of people lost their families and friends and jobs. hurricane sandy was a bad

A hurricane forms when the warm air rises and low air pressure is on the surface of the ocean. Then surrounding air will replace the air that just rose. And that repeats over and over. The air that has risen then cools and turns into clouds. The entire system spins and grows and is fueled by the warmth of the water and water evaporating from the surface.
