A tropical cyclone is a rapidly rotating storm characterized by a low-pressure center, strong winds, and a spiral arrangement of drafts that produce heavy rain. It is seen as a massive with powerful winds, rains, thunderstorms and lightning that usually moves, covering a stretch of 800 - 1000 km. These gather amount of heat and energy through contact with warm ocean waters. Evaporation from the seawater increases their power. Depending on its location and intensity, a tropical cyclone is referred
Tropical Cyclones Introduction You wake up in the morning to the sound of rain rattling against your window. You look down on the floor which is ankle deep with water. The howling of wind fills your ears and you realize that there is a hurricane happening. You are panicking as you go around the house looking for your family but none of them are there. After a few minutes the water has reached you’re reached your head. You can barely breathe anymore as you start to choke. Every year many people are
Hurricanes the Tropical Cyclones What is a hurricane? A hurricane is a tropical cyclone that has a maximum sustained wind of at least 75 mph. The primary energy source for tropical cyclones is the latent heat released when water vapor condenses. Only extremely moist air can supply the energy necessary to spawn and maintain tropical storms, and only very warm air contains enough moisture. Tropical cyclones, therefore, form only over oceans with water temperatures of at least 80 deg F. After they
A tropical cyclone is a warm-core, low-pressure system producing high winds that spiral counter-clockwise (in the northern hemisphere) and inward, with the highest winds near the center of circulation. The large counter-clockwise and inward flow is characteristic of the nearly symmetric structure of tropical cyclones as they are comprised of rain bands spiraling toward the center. These warm-core storms typically form over the tropical and subtropical oceans and extract their energy from the heat

Hurricane Irene affected the Caribbean and much of the United States' east coast and was one of the most damaging tropical cyclones of the 2011 Atlantic tropical cyclone season. Irene originated east of the Lesser Antilles from a well defined Atlantic tropical wave in that area, and became Tropical Storm Irene on August 20, 2011. Irene reached its highest point as a 120 mph Category 3 hurricane. Irene was ranked the seventh costliest hurricane with damages that cost around $15.6 billion in the
hurricanes, otherwise known as tropical-cyclones, are formed over warm ocean waters of at least 26.5ºC through depths of at least 45m. There must also be a high Coriolis Effect present such as there is just north and south of the equator. (Moran, 2011) Hurricanes begin as smaller storms called tropical disturbances, if the storm experiences a sufficient loss in surface air pressure coinciding with a strengthening sustained wind the storm is then upgraded to a tropical depression. As the storm continues
middle of paper ... ...5 and 30 degrees North latitude typically move toward the west. Sometimes the winds in the middle and upper levels of the atmosphere change and steer the cyclone toward the north and northwest. When tropical cyclones reach latitudes near 30 degrees North, they often move northeast” (Tropical Cyclone Climatology). Hurricanes and tornadoes are both similar and different in regards to how they form, where they form, the destruction they cause, and their characteristics. They form

The following are the sample cases of community preparedness and response capacity to disaster in Asian countries. 3.7.1 Bangladesh Bangladesh is one of flood prone countries and it is frequently hit by devastating cyclones, shocking flood and crippling droughts. Bangladesh has intricate river system with three major rivers- the Ganges, the Brahmaputra and the Meghana and it gives the country as a water resource. On the other hand, country is prone to flood disaster
impact on the communities they affected. And what do hurricanes need to form. First off a hurricane is a storm in the category of tropical cyclone. A tropical cyclone is a rotating low-pressure weather system that has organized thunderstorms but it doesn’t have fronts which is a boundary that separates two air masses that are of different densities. Tropical cyclones usually have a maximum sustained surface winds of less
Volcanoes Distribution Volcanoes can be described as being tectonic hazards that occur in many parts of the world. The distribution of volcanoes is closely linked with the positioning of the tectonic plate boundaries across the globe. Today there are about 500 active volcanoes in the world. The world map of volcanoes in your atlas shows that the most volcanic activity occurs along the West coasts of North and South America, (along the Rockies and Andes) and the coasts of many Far East countries
Hurricanes are severe tropical cyclones that have winds greater than 74 miles per hour (120 km/h). Hurricanes form in all of Earth’s tropical oceans except in the cool waters of the South Atlantic Ocean and the South Pacific. To form hurricanes need an abundant supply of very warm ocean water and a disturbance to lift the warm air up and keep it rising. In order to become a hurricane the storm must go through a series of stages. A tropical disturbance, the first stage of a tropical cyclone can originate
track a hurricane Hurricanes, also known as cyclones or typhoons, are huge, devastating tropical storms that can be up to 600 miles wide. They have strong, forceful winds that spiral inward and upward circling around the “eye” of the storm. Inside the eye, there are clear skies and light winds, however, surrounding the eye wall there are bands of wind and rain that spread out for over hundreds or thousands of miles. Hurricanes begin as tropical disturbances over warm ocean water (27°c or 80°F)
INTRODUCTION The term “hurricane” is a name given to violent storms that originate over the tropical or subtropical waters of the Atlantic Ocean, Caribbean Sea, Gulf of Mexico, or North Pacific Ocean. Hurricanes need warm tropical oceans, moisture and light winds above them in order to maintain themselves active. Those storms other than the ones considered typhoons are known as tropical cyclones, which is the general name for all such storms including hurricanes and typhoons. Hurricanes are named
A westward moving tropical wave reached the Caribbean Sea in late May and gradually organized over the next few days. Around 00:00 UTC on June 3, a tropical depression developed about 265 miles (425 km) east of Belize City, Belize. The depression initial moved northwestward, before recurving to the north. The depression entered the Gulf of Mexico and strengthened into Tropical Storm Allison by 12:00 UTC. Despite unfavorable upper-level winds, the storm intensified into a hurricane about 24 hours
swirling, tropical storms that are created with a wind speed over 160 miles (257 kilometers) per hour. It gives off more than 2.4 trillion gallons (9 trillion liters) of rain each day. Hurricane forms in the Southern Atlantic Ocean, Caribbean Sea, Golf of Mexico, and in the Eastern Pacific Ocean. According to www.weatherwizkids.com , a hurricane usually lasts for a week. Hurricane mostly occurs at mid-August to late October and occurs about five to six times a year. A hurricane begins at a tropical disturbance
The Impact Of Hurricanes On The Physical and Human Environment A tropical cyclone is a low-pressure system that forms in the tropics. Hurricane is the name given to fully developed tropical cyclones that are found in the Atlantic Ocean, Caribbean Sea, Gulf of Mexico and the North Pacific Ocean east of the International Date Line. When local residents of an area refer to a hurricane, they are speaking of the violent, stormy weather system that brings torrential rains and destructive, high
there is nothing that you can do except hope and evacuate. Hurricanes are extremely dangerous and should be looked at as such, the amount of damage that they can do is 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
weather condition they produce, and if there are any other names used to describe the same type of storms. Hurricanes are large tropical storms occurring near or on the equator with large amounts of wind and rainfall, accompanied by high humidity and possible flooding. By definition, they must have a wind speed of 119 km/hr, or 74 mph. Technically, only tropical cyclones (the scientific term for hurricane) that form in the Atlantic or eastern Pacific are deemed “hurricanes”. They are formed in a chain
that the storm was upgraded to a tropical depression, you can expect high winds and rain. After hearing this you decide to batten down the hatches so to speak, you close your shutters, get flashlights and maybe shutoff your gas. Feeling sufficiently prepared you go bed satisfied. 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
