Tropical Cyclones in the Southwest Pacific / Cyclone Val Case Study - Jayavi Premaratne
Introduction
A tropical cyclone can be defined as “a rapidly rotating storm system characterized by a low-pressure center, strong winds/gusts, and also a spiral arrangement of thunderstorms that produce heavy rain, damage, and negative effects to people.” Cyclones are also known as hurricanes and typhoons in America and Asia respectively, but in the Pacific and parts of the Indian Ocean, they are most commonly referred to as Cyclones. They generally form 5º to 8º north or south off the equator, where the water temperature is equal to or higher than 26.5 ºC (so sufficient amounts of latent heat is available), and can move further north or south up to roughly 30º off the equator. However, cyclones rarely form within 5º off the equator and they rarely cross the equator (from northern to southern hemisphere, or vice versa) because of the Coriolis effect, which determines the direction that these hazards spin in the north and south hemisphere, by the rotation of the earth. Tropical Cyclones come with many harsh consequences. These include storm surges, strong winds and large amounts of rainfall which all mount to large amounts of both physical and emotional damage. These cyclones which occur often in the Pacific Island region, usually hit an island, on an annual basis at least.
In this essay, I will be focusing on Tropical Cyclones in the Pacific region, and later on, I will more
What is a tropical cyclone: Tropical cyclones are a type of low-pressure systems which generally form in the tropics. They are violent storms, which rotate anti clockwise. Cloud and wind rotates a calm central area, in the tropics (area north or south of the equator) and causes damage to people's properties, death, destruction of recourses, and leaves people severely injured. Tropical cyclones occur
Hurricanes are disastrous forces that destroy homes and families. Making life harder for those already suffering or completely obliterating the financial status of a family. Not to mention the issues it can cause for local wildlife among damage to humans.
Over the past few centuries, the natural disaster of hurricanes has had a huge impact on the land around us. It could cost millions, or even billions of dollars in repairing the damages done by hurricanes. These natural disasters can not only result in property damage but also many lives lost and injured victims. Hurricanes usually leave many without homes, forcing victims to find shelters or relocate to a different city or state for safety. A hurricane is a violent, tropical, cyclonic storm with sustained winds of at least 64 knots (74 miles per hour: 119 kilometers per hour) that are extremely large, powerful, and destructive. Hurricanes usually start to occur over large areas of warm water, such as the Atlantic Ocean. They generally form during the hotter months due to the fact that it gets energy from the heat off the water.
Hurricanes are mainly found in the Atlantic and Caribbean. Hurricanes in the Pacific are called typhoons. A more general term for these storms is a tropical cyclone. Hurricanes are named, and the naming process resets at the beginning
To begin with, “Hurricanes that originated in the northwest Pacific Ocean are called typhoons” (133). Typhoons are
Natural disasters occurring from the climate change could be on the rise. Global warming has been rumored to be causing more hurricanes, typhoons, cyclones, heavier monsoonal rains that cause major flooding, mud slides, and other disasters worldwide. A tropical cyclone, also referred to as hurricanes, typhoons, or cyclones, depending on where in the world the cyclone is occurring, are one of the world’s grandest shows of energy provided by nature. Hurricanes are large, swirling, low pressure storms that have sustained winds of over 74 miles an hour and are formed over warm ocean waters (NASA, n.d.). The purpose of this paper is to discuss hurricanes

Winds of disaster, waves of multitude, preparations galore, the wait is on to determine the outcome of a hurricane. Being one of the most devastating and feared natural disasters, hurricanes are a brutal and unpredictable force. Never knowing what could happen or what they will do, forewarning and preparation for hurricanes are highly recommended. A hurricane is a form of a tropical cyclone or severe tropical storm that occurs in the eastern Pacific Ocean, Caribbean Sea, Southern Atlantic Ocean and Gulf of Mexico (conserve-energy-future.com). The cause of a hurricane is a force of nature, but the effects that follow are to land,
Tropical storms are defined as low pressure systems that form over tropical seas and can devastate areas of human settlements with hurricane force winds and floods. The severity of these impacts varies greatly depending on a countries development levels and is attributable to numerous factors such as: infrastructure, job structure, the provision of service, prediction technology and how much aid is received. Hurricane Katrina and Cyclone are two examples of tropical storms that affected areas drastically apart in economic development.
This is an area over warm ocean waters where rain clouds are building. A tropical disturbance sometimes grows into a tropical depression. This area of rotating thunderstorms has winds of 62 km per hour (38 mph) or less. A tropical depression becomes a tropical storm if its winds reach 63 km per hour (39 mph). A tropical storm becomes a hurricane if its winds reach 119 km per hour (74 mph). Hurricanes are the most violent storms on Earth. They form near the equator over warm ocean waters. Actually, the term hurricane is used only for the storms Atlantic Ocean or eastern Pacific
Most hurricanes that hit the United States begin either in the Caribbean or the Atlantic. Many of the worst start as seedlings coming off the coast of Africa. Like all tropical cyclones, a hurricane needs the warm water of the tropics, which feeds a storm with energy, in order to form. Tropical cyclones are like giant engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator. The warm, moist air over the ocean rises upward from near the surface. Because this air moves up and away from the surface, there is less air left near the surface. Another way to say the same thing is that the warm air rises,
A hurricane is unlike the normal cyclones but is a severe tropical storm or cyclone that typically forms in the Atlantic Ocean, Gulf of Mexico, the Eastern Pacific Ocean or the Caribbean Sea. It is usually accompanied by heavy thunderstorms and if in the northern hemisphere, counterclockwise wind circulations near the earth's surface (FEMA, 2013).
Did Hurricane Irma catch you by surprise? Does Hurricane Maria worry you? Fear not, for this essay will surely prepare you for any hurricane, whether or not it is a category five or not.
According to the National Ocean Service, an organization that strives to protect coastal areas, a hurricane is defined as “a type of storm called a tropical cyclone, which forms over tropical waters” (1). That is to say, when a storm sustains winds with a count greater than 74 miles per hour, it is officially classified as being a hurricane. Generally originating over the Atlantic Ocean, hurricanes are formed when air from surrounding regions with high pressures rush to low pressure areas, causing the air above such warm, tropical waters to rise. As the warm, moist air rises and slowly cools off, water in the air begins to form clouds. Overtime, the number of clouds and strength of the winds significantly increases as a result of the heat and water evaporating from the ocean’s surface, creating a strong rotating storm that is soon recognized as being a tropical
As hurricanes form, they tend to pose significant problems and have devastating impacts on the ocean, land, and on society. In the ocean, hurricanes cause strong winds to occur which in turn, has a large impact on the shipping market. Hurricanes cause the wind to change direction around the eye, causing chaotic sea swells and waves in which a ship is not able to steer around because the waves come from all
