Informative Speech On Hurricanes

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.

Hurricanes are formed over tropical waters. These intense storms consist of winds over 74 miles per hour (Ahrens & Sampson, 2011). The storms addressed here are Hurricane Katrina and Hurricane Sandy. This paper will explore the contrasts and comparisons between these two horrific storms.

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

The scientific definition of a hurricane is “an intense storm of tropical origin, with sustained winds exceeding 64 knots, which forms over the warm northern Atlantic and eastern North Pacific oceans” (Ahrens 316). Each year, from approximately June 1st to November 30th, the world is forced to suffer through hurricane season. Through the duration of this time period hundreds of storm systems emerge from the tropical regions which surround the equator. From these countless storms over 50 will intensify to hurricane levels.

Most hurricanes that hit the United States begin either in the Caribbean or the Atlantic. Many of the worst start as seedlings coming off the coast of Africa. Like all tropical cyclones, a hurricane needs the warm water of the tropics, which feeds a storm with energy, in order to form. Tropical cyclones are like giant engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator. The warm, moist air over the ocean rises upward from near the surface. Because this air moves up and away from the surface, there is less air left near the surface. Another way to say the same thing is that the warm air rises,

Chapter four of our textbook, while making the aspect of physical geography a priority concerning weather and climate, take special care in introducing the topic of hurricanes as well as changes in air pressure and ocean currents. Hurricanes can be described as low-pressure areas which begin over warm waters. As they develop, hot, humid air at the surface rises which aids in the suction of air. This causes cumulonimbus clouds to appear. The energy these clouds release warms the center which contributes to the distinctively calm core commonly referred to as the eye.

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

Hurricanes begin to be formed in the ocean, from nearby areas, with high air pressure, reach into the areas with lower air pressure. One the different air pressures combine, the air becomes warm, causing it to rise. When it is rising, the nearby air swirls around the area left behind by the air that rose. The storm starts to swirl, quicker and quicker, it creates an “eye” is created in the center. The

Did you know that Hurricanes have killed approximately 1.9 million people worldwide over the past 200 years. (Karen lenhardt said in her 2017 article on facts about hurricanes). We are seeing more and more of these occur, this year we have already encountered 13 named storms, 7 of them being hurricanes. Only four other seasons since 1995 have had that many by Sept. 18. Just two more by the end of the year would put 2017 in the top 15 since 1851. Maggie Astor stated in her New York Times news report about the 2017 Hurricane season . We must take notice and learn about the hurricane process so that we are able to understand the stages that hurricanes go through to get to be so fierce and devastating to get the strength to kill that many people.

Hurricanes are one of nature’s most natural occurrences and intense phenomenal storms. Yet, as phenomenal as they are, they are still one of the deadliest and disastrous natural occurrences that continue to plague costal residents with fears of their homes being destroyed, their towns wiped out, and loved ones either disappearing or dying.

It takes many things to create a hurricane for example. Water vapor, “water vapor is the fuel for a hurricane because it releases the latent heat of condensation” according to Weather questions and answers.com. When the condensation comes together it forms a cloud which then forms rain warming the air around it. Usually the wind would take care of the low pressure which would result in a tropical thunderstorm but in some rare cases the wind blows over the top causing lower pressure which would result in a Hurricane.

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.

Hurricanes, which start out as tropical storms, form over the warm moist waters of the pacific and Atlantic oceans near the equator. Near the Philippines and the China sea hurricanes are instead known as typhoons. Water evaporates and rises until large amounts of moist air begin to twist into the atmosphere. The winds circulate counterclockwise north of the equator and clockwise to the south of it. The center of the storm is peaceful and is known as the eye. As long as the hurricane remains over waters of 79 degrees or warmer, it will continue to pull water from the surface which in turn causes it to grow in size and force. When a hurricane moves over land or cooler waters, it will start to slow until the winds are no longer forceful enough to sustain the storm. There are 10-15 hurricanes each year.
