Hurricanes get their start over the warm tropical waters of the North Atlantic Ocean near the equator. Most hurricanes appear in late summer or early fall, when sea temperatures are at their highest. The warm waters heats the air above it, and the updrafts of warm, moist air begin to rise. Day after day the fluffy cumuli form atop the updrafts. But the cloud tops rarely rise higher than about 6,000 feet. At that height in the tropics, there is usually a layer of warm, dry air that acts like an invisible ceiling or lid. Once in a while, something happens in the upper air that destroys this lid. Scientist don not know how this happens. But when it does, it's the first step in the birth of a hurricane. With the lid off, the warm, moist air rises higher and higher. Heat energy, released as the water vapor in the air condenses. As it condenses it drives the upper drafts to heights of 50,000 to 60,000 feet. The cumuli become towering thunderheads. From outside the storm area, air moves in over the sea surface to replace the air soaring upwards in the
Thunderheads. The air begins swirling around the storm center, for the same reason that the air swirls around a tornado center. As this air swirls in over the sea surface, it soaks up more and more water vapor. At the storm center, this new supply of water vapor gets pulled into the thunderhead updrafts, releasing still more energy as the water vapor condenses. This makes the updrafts rise faster, pulling in even larger amounts of air and water vapor from the storm's edges. And as the updrafts speed up, air swirls faster and faster around the storm center. The storm clouds, moving with the swirling air, form a coil. In a few days the hurricane will have grown greatly in size and power. The swirling shape of the winds of the hurricane is shaped like a doughnut. At the center of this giant "dough-nut" is a cloudless, hole usually having a radius of 10 miles. Through it, the blue waters of the ocean can be seen. The hurricane's wind speed near the center of the hurricane ranges from 75 miles to 150 miles per hour. The winds of a forming hurricane tend to pull away from the center as the wind speed increases. When the winds move fast enough, the "hole" develops.
Nearly 45 years ago one of the most powerful and damaging weather phenomenon’s ever to be recorded slammed into the shores of the Gulf of Mexico, a storm that effected people far and wide. Camille formed on August 14th just west of the Cayman Islands and rapidly intensified overnight becoming a category 3 hurricane approaching the island of Cuba. The storm trekked north-northwestward across the Gulf and became a stage 5 hurricane and maintained its strength before making landfall on the Mississippi Coast on the eve of August 17th. The devastating aftermath in the weeks to follow induced by the winds, surges, and rainfall took the lives of 256 people, and caused an estimated damage of 1.421 billion dollars.
While the story is focused on Liesel, it’s told through the perspective of Death. Death, of course, is what takes your soul from your body and takes you to the afterlife. “It suffices to say that at some point in time, I will be standing over you…” (Zusak 4). Liesel is just 9 years old at the beginning of the book. After losing her family she feels hopeless. But eventually she is somewhat happy with her new family and Max, who is hiding in their basement. She becomes intrigued by books and writing. One day, she steals and book from a book burning, which was a serious crime in Nazi Germany and she’s seen by the Mayor’s wife Isla Hermann. Isla invites Liesel to her library and that leads to Liesel becoming more obsessed with writing. She eventually comes to realize that along with the hope that the written word brings-the stories Max wrote for her and even her own writing-is also the source of her pain and suffering because of Hitler’s propaganda. This is one of the things that...
It is truly one of hurricane lore’s greatest storms. Such greatness had innocuous and humble beginnings. Like all hurricanes that have existed, is existing, and will exist, the hurricane originated within the waters of the world and from the winds of the world. The temperate waters of the eastern North Atlantic Ocean gave rise to the storm upon August 31, 1900. Its birthplace is roughly 400 miles west of Africa’s Cape Verde Islands (Longshore).
Hurricane Betsy developed east of the Windward Islands. This means that Betsy occurred in the Atlantic Basin, which includes the North Atlantic Ocean, the Gulf of Mexico, and the Caribbean Sea. Many hurricanes form in this area since it is near the equator and warm water, which is a requirement to form a hurricane is always available. In fact, hurricanes or tropical cyclones can only form if they meet four conditions. First, the temperature of ocean waters must be 82 degrees F or warmer in order. Moreover, low air pressure is needed. Furthermore, you need tropical winds located near the equator. Lastly, you need moist ocean air. The most important part is the warm air since it serves as energy for the storm. The air then rises into the low pressure are and cold air replaces it; this is what then produces what is called a disturbance, which is an area of heavy rainfall, thunder clouds and powerful winds. From here a hurricane can only get stronger and its wind speed is measured and depending on how powerful the storm is it is then assigned into one of five categories.
Hurricane preparation is the most important thing in staying safe during a hurricane. Through technology we are able to track these hurricanes and have time to get ready for them. Recovery takes a lot of time and work, but safety and injury prevention should be your number one concern.
Liesel’s mom leaves her with foster parents because she wishes to protect her from the fate she is enduring. The words Paula, Liesel’s mom, uses go against Hitler because she is a communist which resulted in her being taken away and Liesel to lose her mother and experience the loss of her. This shows Liesel experiences unhappiness because of her mother’s disappearance which is caused by the words she openly uses that contradicts Hitler.
Hurricanes form over the ocean. Easterly waves, what hurricanes develop from, are long, narrow regions of low pressure which occur in ocean winds called trade winds. At first, these easterly waves can grow into something called, a tropical depression. A tropical depression occurs when winds are up to 31 mph. Then tropical depressions can be upgraded into a tropical storm if the winds reach speeds of 74 mph or less. Then finally a the storm can be bumped up into a hurricane if the winds reach 75 mph.
Hurricanes are born over the warm waters of tropical oceans and are formed by a low-pressure system caused by the heating of water. The heat causes the air to rise and form lower pressures in a feedback loop, making the hurricane stronger. Heavy rain results from a condensation of water and strong winds develop from warm air rushing to the eye of the hurricane. Essentially, greater storms and winds occur when the hurricane feeds of the rising temperature of the water. In addition, researchers studied disturbances and intense thunderstorms in the atmosphere over Western Africa and believe they are partly to blame for extreme hurricanes affecting the United States and Canada. While these are all the main ingredients of a perfectly natural process, they were not the primary causes of the damage done by Hurricane
When a tornado forms or passes over a water surface, it is termed a waterspout. Like tornadoes, they may assume many shapes and often occur in series or families. Measurements of their forward speeds are scarce, but estimates vary from a few kilometers an hour to as high as 64 to 80 kilometers per hour. Contrary to popular opinion, a waterspout does not "suck up" water to great heights; though it may lift the water level a few meters. The main visible cloud consists mostly of freshwater clouds produced by condensation of water vapor; however, a sheath of spray often rotates around the lower portion of the vortex tube. Thousands of vacationers and several scientists witnessed one of the largest and most famous waterspouts, observed near Massachusetts on Aug. 19, 1896. Its height was estimated to be 1,095 meters and its width 256 meters at the crest, 43 meters at center, and 73 meters at the base. The spray surrounding the vortex tube near the water surface was about 200 meters wide and 120 meters high. The spout lasted 35 minutes, disappearing and reappearing three times. Most waterspouts are smaller, with much shorter lives. This exceptional spout is an example of one that apparently was spawned by thunderstorm-squall conditions, similar to those that produce tornadoes over land. There are few authentic cases of large ships ever being destroyed by a spout, although spouts are a dangerous hazard to small vessels. A few intense waterspouts have caused deaths when they moved inland over populated areas.
In the hurricane the mixture of the water and winds can be extremely damaging. The winds are extremely dangerous and usually don’t go faster than about 75 miles per hour but have been documented to go as fast as 85 miles per hour. Due to the fact that hurricanes need water to survive they cannot go too far on land, but that does not stop them from causing billions of dollars in damages. Hurricanes are so dangerous that they were listed number 1 on the Department of Earth and Atmospheric Sciences, Hazard and Disasters list.
Hurricanes begin as tropical disturbances in warm ocean waters with temperatures of at least 80 degrees Fahrenheit. These low pressure systems are served by energy from the warm seas. If a storm reaches wind speeds of 38 miles an hour, it is known as a tropical depression. A tropical depression becomes a tropical storm, and is given a name, when its sustained wind speeds top 39 miles an hour. When a storm’s sustained wind speeds reach 74 miles an hour, it becomes a hurricane and earns a category rating of 1 to 5 on the Saffir-Simpson scale.
Hurricanes originate as tropical disturbances over warm oceans with trade winds. The tropical turbances intensify into tropical depressions, and eventually into a tropical storm. They only originate in the tropical trade winds because the ocean temperatures are quite warm there. Powered from the heat that the sea gives off, they are steered by the east trade winds and the temperate west ones, as well as by their own ferocious energy. Around their core, winds grow with a tremendous amount of velocity creating violent seas. As they move toward the shore, they move the ocean inward, while spawning tornadoes and producing torrential rains and floods.
A Hurricane is a tropical storm with winds more than 74 miles per hour (mph). Hurricane wind damage is influenced by the duration and change of wind direction, amount of rainfall and how well land structures are build. Hurricanes are measure in five different categories and each category can produce different degree of damages. Category One Hurricane has sustained winds 74-95 mph. Category Two Hurricane has sustained winds of 96-110 mph with very strong winds that can produce widespread damage and extensive damage to power lines. Category Three Hurricane has sustained winds of 111-130 mph that will cause extensive damage with near total power loss that could last several days to weeks. Category Four Hurricane has sustained winds of 131-155 with extremely dangerous winds causing devastating damage. Finally, a category five hurricane has sustained winds greater than 155 mph. This is a catastrophic damage storm. Category five can have severe injury or death due to wind blown debris. A Category five hurricane can produce extensive power outages that will last for weeks to perhaps months. Therefor...
A hurricane is a type of natural disaster that can be harmful and destructive to anything in its way. Every year five to six hurricanes are formed, damaging and destroying people’s homes, landmarks, and anything in its path (“Hurricane”). Before a hurricane is developed it is known as a tropical storm. To be a tropical storm wind speed must be at least thirty eight miles per hour (“Hurricane”). Once wind speeds reaches seventy four miles an hour it can then be classified as hurricane (“Hurricane”). Large scale storms, like hurricanes have a variety of ways to measure the sev...
