Concluded substitute of the original eyewall by an outer, concentric eyewall while Andrew lingered at sea;
Eyewall replacement cycles can encompass extremely severe penalties, mainly when they take place just before landfall
At an immense price to living and possessions, Hurricane Andrew unpredictably fortified to a Category 5 hurricane while it landed in southeastern Florida right after an eyewall replacement cycle
Massive and swift-forced sways usually causes hurricanes to develop bigger as well as eyewall replacement cycles
Storm transformation so quick the eye crossed the inhabited coastline before the manipulation of land could substantially make it weaker;
Hurricane Andrew’s eyewall had continual winds of 145 mph before landfall in South
Florida Wind gusts were roughly 175 mph, which resulted in a Category Four Hurricane Intense wind speed, 82 m/s calculated by aircraft flying at 2.5 km; The momentum of this wind was predicted to have transpired within the eyewall in an open environment for instance at an airport, at the typical 10-meter altitude The wind at other locations inland was subject to intricate exchanges of the airflow with buildings, trees, and other barriers in its course.Development of an extreme, although non-tornadic, convective vortex in the eyewall during landfall Hurricane Andrew contained forceful convection and reintensifed quickly as it passed onshore, even though it destabilized for 12 hours during the eyewall replacement. The Gulf Stream just offshore was sufficiently warm in order to sustain a sea level pressure 20-30 hPa lower than the 922 hPa reached, but the storm hit land before it could attain this potential. The unpredictable mesoscale and vortex-scale occurrence launched the course of events on that windy morning.
In 1992, hurricane Andrew was a category four hurricane and said to be one of the worst natural disasters to happen in the United States at the time. It’s winds surpassed 160 miles per hour and caused damage to over 125,000 homes within 400 square miles. Hurricane Andrew left approximately 175,000 families and children temporarily homeless.
Some of the damage done by Hurricane Katrina could have potentially been avoided if protection systems were installed to the proper extents. In Louisiana, “some parts of the metro area continue to lack hurricane protection built to federal standards” (Webster). Had the greater Louisiana area been better protected, it is very likely that more people would have survived and the total cost of the storm been less. Even in areas where levees...

...o something that could be safe and withstand the wanted forces of future hurricanes. The delays also served as a problem in the decision because it added to the overall cost and set back the construction of the levees. I studied the levee break during Katrina because I wanted to find out why the engineers decided to design for smaller hurricane forces so that my reader can better understand that the engineers may have underestimated the potential harm to public. I believe that the decisions made about the levee design could have been different and that the changes in design could have possibly prevented some, or most of the damage caused by Katrina in 2005.

Imagine that a family is sitting at home watching a calm game of baseball, when suddenly they realize that a massive wall of water is approaching the neighborhood. Where did this flash flood come from, a reader might ask? The wall of water was made by the raging winds and immense power of Hurricane Andrew. Hurricane Andrew was the second most expensive storm in history that destroyed over 250,000 homes in the states of Florida and Louisiana alone. Hurricane Andrew was not predicted to make landfall, so when it did many civilians did not have any ideas that the Hurricane was coming until it was almost too late. Hurricane Andrew also caused many short and long term effects in the ecosystem and local economies.
The category 3 storm changed the lives of the residence who lived there forever. The storm in combination with the fault of the man-made flood protection walls (levee’s) resulted in the death of at least 1,300 people (1). With nearly half the victims over the age of 74, deaths were caused by; drowning, injury/ trauma and heart conditions (2). Hurricane Katrina was one of the most costliest storms to land on American soil, costing around US$135 billion in damages (3). Although the number of deaths caused by Hurricane Katrina are not as high as other natural disasters, Katrina displaced a massive amount of people from their homes, around 85% of the population were displaced directly after the storm hit (6). Being one of the most devastating natural disasters to hit the United States, Hurricane Katrina impacted not only the residence of New Orleans by also many of the surrounding
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 powerful and destructive storms that involve great rain and wind. The United States of America has dealt with many hurricanes that have cost a great amount of damage. However, there is one hurricane that happened in 2005 that stands out among the others, Hurricane Katrina. Hurricane Katrina was one of the worst hurricanes to hit the United States, a category 5 on the Saffir/Simpson Hurricane Scale. An estimated 1836 people died because of the hurricane and the floodings that happened after (Zimmermann 1). Katrina initially beg...
That eye would break the record for lowest recorded pressure for an Atlantic hurricane that did not reach category 5, at 919 millibars, until Hurricane Opal in 1995 (National Weather Service). When winds, rain, and debris faded to quiet, my father, along with my grandma and most of the neighborhood, decided to walk outside and look around. It did not last long- thirty years later, he estimates about 15 minutes at most. It was eerie and unsettling, as he described it: “The lighting was all wrong- it was like a scene from a horror movie. I was waiting for the guy in the mask to pop out.” They could see the debris that had been thrown around, and the storms in the distance. Soon enough, the winds started to pick back up, and everyone hurried back
Later that night you’re awakened by what you can only describe a roaring sound and you realize that the storm sounds worse, you turn on the TV and the storm’s been upgraded to a tropical storm and now you can expect winds 40 mph winds and it’s only going to get worse. Now picture that it’s 1975 and you live in the Henan Province, where the housing and infrastructure aren’t up to the task that nature has set for them. There are houses today in many developed countries that cannot withstand a hurricane or a typhoon. In 1975 the Chinese and Taiwanese were overwhelmed by nature.
Hurricanes require the upwelling of warm and moist air for them to keep on going A tropical storm is considered a hurricane when its winds are greater than 74 miles per hour. Hurricanes only occur in the summer months when the water temperature is above 79 degrees Fahrenheit. The lifespan of a hurricane can last about two weeks while traveling over an ocean, and can generate enough energy to travel along the whole Atlantic coast. A hurricane comes to an end when high wind speeds tear the hurricane apart or when there is no longer enough warm moisture to keep it intact. This happens when a hurricane travels over cooler waters or over land masses. Although a hurricane is coming to its end, though, it can still be rejuvenated if it moves to a region that has the warm moisture it needs to survive, or if it joins another storm system. Of all of nature’s forces that exist hurricanes could be considered one of the most powerful of all these forces that can cause tremendous amounts of destruction is such a little amount of time. A hurricane is a powerful whirling storm of winds that measure 200-300 miles in diameter. Hurricanes are an area of low pressure that forms over the oceans in tropical regions in either the North Atlantic Ocean or eastern North Pacific
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...
