Tropical cyclone Essays

[1] However, tropical cyclogenesis began with the development of a tropical depression on June 13.[2] There was a total of seven tropical storms, five of them strengthened into hurricanes, while two of those became major hurricanes – Category 3 or higher on the modern day Saffir–Simpson scale.[3] The final system, a tropical depression, was absorbed by a cold front on December 1, one month after the official end of the season on November 1, 1947.[1] Four hurricanes and four tropical storms made landfall

Introduction A hurricane is a type of storm called a tropical cyclone, which forms over tropical or subtropical water (NOAA’s National Ocean Service). when a storm’s wind speed is 74 mph it is called as hurricane. Hurricanes form in Atlantic basin. Different examples of hurricane are hurricane Katrina and Hurricane Sandy that made massive destruction in their areas. The warm and moist air rises over the ocean surface, this air moves up and away from the surface and then there is less air left near

Cyclone Tracey – Topic question: Why was Tropical Cyclone Tracey so significant to Australia? Initial Research: Tropical Cyclone Tracey was a small but catastrophic that hit Darwin in 25th of December 1974 and lasted two days. Accounted of 65 lives and destroyed lots of infrastructure and environment. Winds going at a pace of 50km/h and then hitting speeds of at 217km/h. Within 3 weeks, the cyclone lead to 2/3 of the population leaving to find safety. Why have I decided to do Tropical Cyclone

According to the National Aeronautics and Space Administration (NASA), hurricanes, or tropical cyclones, are storms that usually in warm ocean waters with low vertical shears, or winds that do not change in speed as it travels up in the atmosphere. This phenomenon begins with a small distribution of rain clouds above warm sea water that eventually builds up into a tropical storm, with wind speeds reaching 63 kilometers per hour. Under the right conditions, the storm will gain rapid wind speeds of

of the fatalities were children and majority of them lived near the Matina River. What happened is that on the two hours duration 8mm of rain fell and it was classified as heavy rain. It was also type of isolated thunderstorm embedded in the inter-tropical convergence zone. Juna Subdivision is a village situated near the Davao River and Davao Gulf that makes the place susceptible from flooding because of its existing ground elevation and its location being near the sea water level. It only implies

form in the late summer and fall when the sun heats the ocean water to over 82 degrees fahrenheit. Most hurricanes in the Atlantic Ocean start off the west coast of Africa as thunderstorms. Strong winds combine with the thunderstorms to create a tropical storm. As the storm moves over the ocean, it sucks in warm water like a vacuum which gives power to the storm. When the wind speeds reach 75 miles per hour or higher the storm becomes a hurricane. Hurricanes in the northern hemisphere form to

that left the East coast of the United States. On October 28th a extratropical cyclone progressed along a cold front to the East of Nova Scotia. On Oct 27th, Hurricane Grace developed from a pre existing subtropical storm and was originally moving northeastward, had made a turn and headed east. Hurricane Grace was drifted upwards by its cold front into a warm zone of circulation of the deep cyclone on Oct 29th. The cyclone strikingly got stronger as a result of a temperature contrast between the cold

Sandy” 1). Hurricane Sandy, a late season tropical cyclone, affected the east coast of the United States and seven of the Caribbean nations ("Superstorm Sandy"1). Hurricane Sandy was the deadliest hurricane in the 2012 hurricane season ("Superstorm Sandy"1). Hurricane Sandy started October 22, 2012 and lasted through October 31, 2012. Sandy started in Atlantic City, New Jersey and ended in the Caribbean Sea ("Superstorm Sandy"1). Due to tropical waters and cyclone-like wind conditions, Hurricane Sandy

That hurricane turned out to be the tropical storm, Hurricane Dolly. A storm that would later be the 4th most destructive hurricane on record that has hit Texas. A hurricane is first created by the formation of low pressure areas over warm ocean waters that take place within the warmer seasons. Water vapor is the source of a hurricane’s

called a tropical disturbance. The tropical disturbance then moves on to being a tropical depression when its winds reach 38 mph or less. The tropical depression then turns into a tropical storm when its winds reach 39-73 mph and finally, the tropical storm reaches its hurricane stage when it reaches 74 mph. Two main things are needed to create a hurricane, ocean water over 79°F, and a wind that doesn’t change much in speed and in direction. If a tropical depression turns into a tropical storm, it

Hurricanes can cause extensive damage and destroy whole cities. Such as Hurricane Katrina in New Orleans August 23rd through August 31st. Hurricanes are massive storms that form over the ocean, and can destroy whole cities. Before a hurricane occurs, and while it grows, there will be. Flash floods because of extensive amounts of rain flooding will occur quickly and without much warning. There will also be very strong winds, anywhere from 74 miles per hour to over 156 miles per hour. This wind is

Jordan Bartell GEOL 108 - Hye Jung Lee 11/19/2015 Hurricane Katrina On August 29th, 2005, Hurricane Katrina hit New Orleans, LA. This devastating event led to hundreds of fatalities, poverty, and extreme despondency for years. Today, the affects can still be seen in specific locations across the city of New Orleans, and while many citizens have found their way back to living as though they did before the catastrophe, their memories of the event are vivid and their concerns for future hurricanes

certain that a hurricane that can do much more damage than a tornado. There are many differences between a hurricane and a tornado but yet a few similarities between both. Hurricanes and tornados have a few similarities. They are both considered tropical cyclones. Both have very strong winds that can do a lot of damage. They are measured by wind speed. Hurricanes and tornadoes both do rotating winds. Both can cause a lot of damage. Tornadoes are usually caused when warm and humidity are in the lower

is the hurricane because of its effects to the damage of property,environment,and death toll. Hurricanes are one of the many natural disasters that occur on earth.According to a national geographic article hurricanes are,”giant,swirling tropical storms that can pack wind speeds over 160 miles an hour and unleash more than 2.4 trillion gallons of rain a day.”Hurricanes have a lot of precipitation which means that

make landfall in the United States since Wilma in two-thousand five. In four day’s many areas received more than forty inches of rain as the system come over eastern Texas and near waters, causing catastrophic flooding. Harvey was the wettest tropical cyclone on record in the United States, it resulted in the flooding of hundreds of thousands of homes and it displaced thirty thousand

hurricane. In order for one of these storms to be considered a hurricane it has to reach a certain wind speed. If the wind has gotten up to 38 miles per hour with a closed circulation formation it is considered to be a tropical depression. The next level up from that is what is known as a tropical storm; when winds reach up to 39 to 73 miles per hour. Then, finally, a hurricane is officially declared when the winds in a storm reach or surpass 74 miles per hour. Although, 73 miles per hour is the minimum speed

the east coast along the United States. Hurricanes cause wide havoc to many coastal cities and inland cities and are very dangerous. First, there are many causes of hurricanes. Hurricanes are a storm with violent wind in particular a tropical cyclone in the tropics. A hurricane forms from a bunch of other storms that form into one that becomes very dangerous. Before a hurricane comes it usually rains a lot and it also rains a lot. When the hurricane comes the rain looks like it’s raining

hurricane is very complex with many conditions that need to be met in order for it to properly form. A tropical thunderstorm is what starts it all. Occasionally, a few thunderstorms begin orbiting around an area of low pressure (warm area). These rotating thunderstorms are referred to as a tropical depression. If the depression increases in strength so that its winds reach 39 mph, it is classified as a tropical storm. Then, if wind speeds

just weeks earlier, were unprepared to handle the increased demand, and many companies chose to stop operations and leave the Islands in the following year. In response the Hurricane Relief Fund was enacted in 1993, but after 7 years with no major tropical activity impacting Hawaii, the fund was stopped in

severe damages to houses and also at least 103 deaths total. This devastating storm definitely left a mark on the Galveston people forever. At this point I know what you’re thinking how did hurricane Ike start? Hurricane Ike started like any other tropical cyclone. It started over the warm waters of the Gulf of Mexico. All hurricanes form over warm oceans near the equator because moist air is needed to fuel them. The moist air rises up causing the areas below to have a lower air pressure. As the warm
