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 are mainly found in the Atlantic and Caribbean. Hurricanes in the Pacific are called typhoons. A more general term for these storms is a tropical cyclone. Hurricanes are named, and the naming process resets at the beginning
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
Tornadoes and hurricanes are very destructive. Tornadoes are spinning columns of air that form from the the sky to the ground. Hurricanes are the most powerful storms on Earth. Hurricanes are tropical storms that travel across the Atlantic Ocean. Hurricanes happen when winds exceed to 75 miles per hour. Tornadoes have winds that can get to the speed of up to 200-300 miles per hour. There is a level 5 hurricane which means that the winds exceed up to 150 miles per hour.
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.
When warm water, moist air, and strong winds collide and create a rotating bundle of thunderstorms create a rotating bundle of thunderstorms and clouds a hurricane is formed. Hurricane send when they lose their source of energy by traveling over land or cold water. Hurricanes occur in the Atlantic Ocean, the Gulf of Mexico, and the Eastern Pacific Ocean. Hurricane season is either from June 1-November 30 or mid-August to mid-September. Hurricanes can last for a few hours to at least 2 weeks depending on its size. The Saffir-Simpson Hurricane Wind Scale rates, or categorizes, hurricanes. Hurricane names rotate each year but, if a hurricane is strong enough that name is retired.
Hurricanes are known for heavy winds, rain, and the damage. Hurricane winds are known to reach speeds of 100 mph. Hurricanes have heavy rainfall that could last for days, or weeks at the most. Hurricanes can also start floods, which will bring me into my next statement. Hurricanes can cause trees to fall which causes damage to houses, and even people! The average number of kill’s for a hurricane are approximately over 80 thousand people.
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.
In fact hurricanes start over warm waters near the equator and the come North West. Hurricanes normally start out at tropical surges and by the time they hit land they are large, swirling storms with strong winds that blow 74 mph winds or higher. In addition they start out as tropical disturbances. Every time they know a hurricane is coming they name it so that if there are many at once they can’t call then hurricane, that means that everyone would not know what hurricane hit where. Along with the scientist trying to figure out how these hurricanes start NASA is also trying to at the same time so they are helping each other. In the same manner there are different parts to a hurricane, there is the eye, the eye wall and the rain bands, along
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.
What are the differences between hurricanes and tornadoes? Hurricanes and tornadoes have many similarities, such as their formation and safety but they have some differences as well. Over 80 tornadoes are reported in the United States every year, but many more hurricanes are reported however, only the extremely dangerous ones get on the media. Hurricanes usually happen on the coast, while tornadoes happen on warm dry areas. In the next few paragraphs you will learn about how hurricanes and tornadoes form, the worst hurricanes and tornadoes in history, and how you can prepare for them.
To start off, hurricanes and tornadoes have deathly strong winds. During a hurricanes , wind speed can get up to 300 miles per hour.(Source 4). That is faster than a cheetah. There fore, it is strong enough to blow a roof off a house. In fact, tornados get no where close to the wind speed. According to Source 4, there winds speeds can rang from 74mph-150 mph. But I don’t think that is as fast as they go. I think that they can go faster. A tornado has a path where is goes through most the time. But sometimes it can completely destroy a town and leave they next time interiorly untouched. Also. in they eye of the hurricane, it has no wind what so ever.
Water vapour is the "fuel" for hurricanes because when it condenses to form clouds and rain it warms the surrounding air. The heat builds up causing low pressure to form. The low pressure causes the wind to spiral towards the centre
