Hurricanes get their energy from low pressure zones in the tropical latitudes. Cooler waters or a change in wind speed or direction are some factors that weaken hurricanes. Hurricanes grow in strength over warm waters because there is more moisture in the air which helps cloud formation, which in turn strengthen the storms. So with cooler water there would be less moisture in the air which in turn would slow the hurricane down. A change in wind direction or speed would cause a mixing of the drier air into…
A hurricane’s energy comes from the transfer of both sensible and latent heat from the surface of the ocean. A cluster of thunderstorms must form around an area of low pressure for a hurricane to form. Warm water drives a hurricane, so when it moves over an area of colder water it slows down and begins to decay. A rising wind shear aloft also hinders a hurricanes momentum. Land does weaken more quickly when it makes land fall. The terrain tends to break up its wind movements, slowing it rapidly. Land also helps to suck the moisture out of the storm which further aids in its rapid decay.…
After reading, Why This Hurricane Season Has Been So Catastrophic, by Michael Greshko I’ve come to understand that climate change isn’t “directly” linked to specific environmental events, but can be used to explain such natural phenomena and their extremity, like hurricanes. Even though the article was not specifically geared for discussing climate change, it posed a specific type of natural disaster, hurricanes, which can be excited by climate change. In the article, Greshko specifically explains that climate change increases average temperatures, and this can lead to more rainfall in individual hurricanes since warmer air can hold larger amounts of water vapor (par. 29). This struck me as a very specific example for how climate change can…
Hurricanes can form very quickly and destroy communities in only a few days. Hurricanes are caused by warm, moist air being present over the ocean. The air rises up near the surface. The warm air rises so there is low pressure below. Air from nearby areas with higher pressure moves to areas with lower pressure. That air turns warm and moist and then rises. The surrounding air takes the place of that air. As the warm air cools, water in the air turns into clouds. The clouds and winds spin and grow, collecting the oceans heat and water from the surface (Erickson and Leon, 2017, p. 1-5). While the storm continues to grow it will reach different stages. At 38 miles per hour it is considered a tropical depression. Tropical depressions then become tropical storms and are given a name. Every six years a list of names is reused. These…
“Hurricanes derive their energy from the warm, tropical oceans and by evaporating water from the ocean's surface. Heat energy is converted to wind energy when the water vapor condenses and latent heat is released inside deep convective clouds” (Ahrens, 2014, p. 341). Hurricanes can weaken more quickly if it moves over cooler water, because they get their energy from warm tropical oceans.…
A hurricane starts as mass amounts of wind. What happens is the pressure drops. There is sometimes a storm and usually a mass amount of clouds. The weather would be cloudy and rainy during the storm.…
A hurricane is when the winds in a tropical depression rotate counterclockwise at more than seventy-seven miles per hour.…
A category 5 hurricane can reach up to 155 mph winds (USA TODAY). There were already 3 hurricanes in the 20th century. I think you should evacuate the city even if it's not that severe just to be safe. It's for your own safety.…
Since the very first colony was founded in 1607 in Jamestown, Virginia, religion played a very important role in America. Nine of the thirteen colonies had established churches. Having an established church meant you paid taxes for the support of that church whether or not you were a member. The colonies with official state or established churches of the Congregational (Puritan) church denomination consisted of Maine, Connecticut, and Vermont. Colonies that remained a part of the original Church of the England were Virginia, Maryland, North Carolina, South Carolina, Georgia, and New York.…
A hurricane is a large, swirling storm with strong winds, that can blow up to 74 miles per hour or higher. Second, a hurricane is categorized by its wind speed using the Saffir-Simpson Hurricane Scale, the highest is a Category 5, which is 157 mph or similar, or close, to the speed of some high-speed trains. Third, hurricanes are named, because more than one may exist at the same time, names also make it easier to keep track of and talk about storms. In addition, NASA scientists collect information on clouds, rainfall, wind, and the temperature of the ocean's surface. Also, NASA is developing several ways to help scientists better understand hurricanes, one of them is the Hurricane Imaging Radiometer, it will be carried by an airplane or…
Hurricanes are powerful and dangerous storms that involve great rain and win. When a tropical storm has a wind speed greater than 75 miles per hour, it is considered a hurricane. The United States of America has dealt with many hurricanes that have cost a substantial amount of damage. However there is one hurricane that occurred in 2005 that stands out among the others, Hurricane Katrina. Hurricane Katrina was the deadliest and most destructive of the Atlantic Hurricanes during the hurricane season. Hurricane Katrina had a great economic and environmental impact on the United States which will take time to completely recover from.…
First, we have to know the powerful characteristics of a hurricane. Winds start blowing in a huge circular motion. All hurricanes, big or small, start at winds around 75 mph. Once a hurricane starts, it feeds on warm water. Warm water is not necessary for a hurricane, but it makes the hurricane bigger and stronger. The worst part of the storm is the eyewall, where big storms produce winds of at most 350 mph.…
There are a ton of differences between tornadoes and hurricanes. One is that tornadoes form on land and hurricanes develop over warm, tropical waters. A tornado only lasts a few minutes while a hurricane can last up to ten days. Since the hurricane is much larger than a tornado, a hurricane can release tornadoes and a hurricane gets a name after it is down destroying a place because it makes it easier to identify it. The "eye" of a hurricane can be up to 20 miles long and the tornades "eye" can only be a few feet in diameter. Tornadoes occur from April to June and hurricane occur from June to November. A tornado travels from south west to north east and a hurricane travels from east to west. Tornadoes have been spotted in every continent except Antarctica.…
Hurricane Katrina lasted for days. It originally formed on the south eastern part of the Bahamas on August 23,2005 according to, Kim Ann Zimmermann, an author of live Science. Hurricane Katrina then made its way to the southern parts of Florida as a category one hurricane on August 25,2005. On August 26,2005 Katrina re-intensified into a hurricane and then became a category five on August 26th according to Zimmermann. It then weakened to a category three before it made landfall along the Louisiana-Mississippi border. Hurricanes form over warm oceans near the equator. The warm, moist air rises up from the ocean surface causing an area of low air pressure. According to a NASA Official, Kirsten Erickson, air from the high pressure begins to push into the low pressure and the “new” air becomes warm and moist, too. The warmed moist air rises and cools off then the water in the air forms clouds. According to Erickson, the systems of clouds and wind spins and grows, fed by the oceans heat. The storm begins to rotate faster and faster forming the eye which is located in the center of the hurricane. The Hurricane is fed by the oceans heat so once It hits land it’s not as powerful. http://spaceplace.nasa.gov/hurricanes/en/…
Hurricanes are giant sea storms that rotate in a giant circle. It carries winds blowing at speeds of at least 74 miles per hour. Hurricanes form in tropical regions. They form there because they need warm water of at least 80º Fahrenheit, high humidity with moist air, light winds, and very warm surface temperatures. Some of the strongest hurricanes carry winds having speed of at least 200 miles. When these strong winds reach the shores it destroy houses, uproot trees, and hurl almost anything into the air as if it’s a bullet.…
