Hurricanes

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

Hurricanes form over the equator in warm ocean waters. First in a hurricane the winds start to pick up wind on the average reach about 39-73 mile per hour,th but in the great Galveston the winds reached 145 miles per hour the power of the wind can take down trees, houses and building. it rains very hard it is not uncommon during a hurricane to get 5-10 inches of rain. It’s also very common to get floods from the storm surge that averages 25-28 feet above sea level. Even though it is very rare tornadoes

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 destructive, they form out of the middle-east of the Atlantic Ocean. They form from the ocean and form into cyclones with strong winds up into 110 mph winds and a lot of rain clouds.

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.

Hurricanes are big storms in the ocean that are large, swirling storms with strong winds. The water that is pushed onto land is a storm surge and it is said that they are the most dangerous part of the hurricanes that go on the land. A Category one, winds can get up to seventy-four miles per hour. Category two, winds can get up to ninety-six miles to one-hundred-ten miles per hour, a Category threes, winds can get up to one-hundred-eleven to one-hundred-twenty-nine miles per hour. Category four hurricanes can get up to one-hundred-thirty miles per hour, Category five hurricanes are the worst ones of all and the wind speeds can get up to one-hundred-fifty-seven miles per hour and then it can destroy anything in it’s path. The Eye of the

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 first start out as a tropical depression and then gain strength into a tropical storm. When a tropical storm reaches 74+ miles per hour they turn into a category 1 hurricane, they increase in intensity, they go all the way through a category 5 hurricane. Category 1 hurricanes have a wind speed of up to 95 mph. A category 2 hurricane has wind speeds of up to 110 mph. Category 3 hurricanes reach up to 129 mph. A category 4 hurricane reaches up to 156 mph. The deadliest hurricane, a category 5 exceeds wind speeds anything above 157 mph. A hurricanes only form over warm waters. Damp air fuels the forming storm. The warm air gets water from the ocean and becomes moist. This moist air rises towards the surface, when air from surrounding

It’s important to understand Geoscience while studying hurricanes. By understanding Geoscience, we understand how the earth heats and cools and this plays a major role in the creation of hurricanes. Hurricanes form when an area of warm water heats the air above it, causing that air to rise. This creates an area of low pressure. The higher pressure around this area pushes new air in, which heats up and also rises. This flow of air causes the clouds to swirl. If the storm is in the northern hemisphere,

So what is a hurricane? A hurricane is a very large, white oval with an eye in the center, like a donut. It can be as large as a state. It is filled with water and wind. But hurricanes aren’t just an interesting figure on the earth. They destroy lives. They demolish homes with one swift stroke. If any people stay behind, it’s likely that they won’t survive. All the water and the wind are too powerful for any life to withstand. (Michael Allaby, 31)

Hurricanes are storms that are usually out in water, but can hit land once in awhile. The storm forms over warm ocean waters, and can catch speeds up to 157 mph. When and if hurricanes reach land the wind will push a wall ocean water on shore which could cause flooding. There are three basic pieces of the hurricane: the eye which is the center, the eyewall which is the ring of thunderstorms around it, and the last of which is the rainbands which are rain clouds and thunderstorms which are outside the eyewall. Lastly they use a scale to categorize it by its wind speed it is called the Saffir-Simpson Hurricane Scale. NASA is researching more than ever they are finding information on the clouds, the wind speeds, rainfall, and even water temperatures.

Hurricanes form when moist air over the ocean rises upward from near the surface. Since the air moves upwards and away from the surface, there is less air near the surface. “As the storm system rotates faster and faster, an eye forms in the center. It is very calm and clear in the eye, with very low air pressure. Higher pressure air from above flows down into the eye.” (https://spaceplace.nasa.gov) The eye of the storm is where most of the formation happens such as the warm and moist air rising from the ocean’s surface and then forming clouds around the eye.

hurricanes in the history of the United States. It is very noticeable that as the population goes down, that the salary levels rise.

Meteorologists have made the lives of the general public as simple as it can be by dividing the development of a hurricane into four stages: tropical disturbance, tropical depression, tropical storm, and a full-fledged hurricane. During a tropical disturbance, water vapor from the warm ocean water condenses to form clouds, which in turn discharges heat into the air. Additionally, the heated air rises and is pulled into the column of clouds. The continued evaporation and condensation is what constructs the cloud columns to be higher and grander. Nevertheless, a pattern develops whereby wind begins to circulate around a center (much like water going down a funnel). The moving column of air continues to combat more clouds, which in turn becomes

Hurricanes are large storms with strong winds, lots of rain, and lots of destruction. These (sometimes) massive storms can blow up to 157 mph! These storms form over an ocean, which has the warm water and winds that have the same speed, and direction which is necessary for a hurricane to form. When they first strike land, these massive storms push a wall of water inland. In the center of the hurricane there is an “eye” or the whole which inside the eye it is calm and sunny. However, on the wall circling the eye is the worst part. Hurricanes start out as a tropical disturbance, and then develops into a hurricane. NASA has satellites, planes, and drones that can fly into the storm to take pictures and tell the people the wind speeds of the
