Typhoon
Typhoon
A Typhoon is a mature tropical cyclone that develops in the western part of the North Pacific Ocean between 180° and 100°E. This region is referred to as the northwest Pacific basin.

TROPICAL CYCLONE
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain. Tropical cyclones are typically between 100 and 4,000 km (62 and 2,485 mi) in diameter. A cyclone is turned into a hurricane when the wind speed reaches 120 kilometres per hour (75 mph).

PAR
Philippine Area of responsibility.This area is bound by an imaginary line drawn along the following coordinates:25°N 120°E, 25°N 135°E, 5°N 135°E, 5°N 115°E, 15°N 115°E, 21°N 120°E and back to the beginning.
TROPICAL DEPRESSION an atmospheric low-pressure system originating in the tropics, specifically, a tropical cyclone in which the maximum sustained wind speed is 38 miles per hour (62 kilometers per hour) or less.
STORM
A storm is any disturbed state of an environment or astronomical body's atmosphere especially affecting its surface, and strongly implying severe weather. It may be marked by significant disruptions to normal conditions such as strong wind, hail, thunder and lightning (a thunderstorm), heavy precipitation (snowstorm, rainstorm), heavy freezing rain (ice storm), strong winds (tropical cyclone, windstorm), or wind transporting some substance through the atmosphere as in a dust storm, blizzard, sandstorm, etc.

SUPER TYPHOON
"Super-typhoon" is a term utilized by the U.S. Joint Typhoon Warning Center for typhoons that reach maximum sustained 1-minute surface winds of at least 65 m/s (130 kt, 150 mph). This is the equivalent of a strong Saffir-Simpson category 4 or category 5

    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…

    When describing a hurricane there are parts that cannot be left out, it’s important to know how these storms start. For a hurricane to start you have to have some type of warm water source and winds that are blowing in the same direction that the hurricane is going, after the main ingredients comes the transformation of the rain clouds and wind. The transformation, is the change into a tropical disturbance, after more wind and more clouds building comes the transformation into a depression, the depression becomes a storm when winds reach 39 mph or over, after the depression comes the Category 1 hurricane. When, hurricanes starts it doesn’t just quit, the winds keep rising causes the damage and the strength to rise with it, along with the strength and damage, the hurricane goes up on the Saffir- Simpson Scale. The Saffir- Simpson Scale ranks the hurricane in categories, Cat 1 (Category 1) has winds from 74- 95 mph, then when wind get over 95 mph it turns into a Cat 2 which has winds of 96-110 mph, next it’s Cat 3 with raging winds of 111- 129 mph, winds keep rising and Cat 3 goes to a Cat 4 (wind speeds 130-156 mph), obviously after Cat 4 it’s a Cat 5 which is the most powerful on there is (winds 157 mph and over).…

    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…

    A Hurricane is a storm with a violent wind where it forms from ranges of categories 1-5 through large areas of rainfall. Hurricanes can also turn into tornadoes depending on the category it is in. Hurricane Katrina (2005) is one in particular that has left the Nation in devastation where many will never forget. The Levee in New Orleans led to massive flooding which caused a catastrophic aftermath and is known as one of the five deadliest Hurricanes in the United States. All in all, Hurricane Katrina had over 1,833 deaths which resulted in an estimation of $108 billion in property damage.…

    Hurricanes start off as tropical depressions (centres of low atmospheric pressure) over tropical oceans. Three things must happen for a hurricane to form. A continuous evaporation and condensation cycle must take place; there must also be patterns of winds that are characterized by the converging winds, and a difference in air pressure between the surface and high altitude. In the warm waters of the eastern Atlantic, water vapour rises from the ocean and then cools forming clouds and releasing heat energy which fuels the storm. This sucks in more warm air generating strong winds which shoots upwards. When this rush of air hits the stratosphere it flattens out and after getting influenced by earth’s rotation the storm starts turning counter clock wise. When the winds reach 39 mph it is considered a tropical storm. If there are aren’t any wind shears the storm’s air in the upper atmosphere will raise to higher and higher pressures resulting in hurricanes. So, Hurricanes are basically like giant engines that use warm, moist air as fuel. The deadly winds caused by hurricanes result in a massive bulge of water called a storm surge by pushing down on the ocean surface. 90% of the casualties in hurricanes are due to the storm surge.…

    Most hurricanes appear in late summer or early fall, when sea temperatures are at their highest. The warm waters heat the air above it, and the updrafts of warm, moist air begin to rise. At that longitude in the tropics, there is usually a layer of warm, dry air that acts like an invisible ceiling or lid. Once in a while, the lid that prevents the hurricane from forming is destroyed. Scientists do not know why this happens; however, when it does, it's the first step in the birth of a hurricane. With the lid off, the warm, moist air rises higher and higher. Heat energy, released as the water vapor in the air, condenses. As it condenses it drives the upper drafts to heights of 50,000 to 60,000 feet. The cumuli clouds become towering thunderheads. From outside the storm area, air moves in over the sea surface to replace the air soaring upwards in the thunderheads. The air begins swirling around the storm center, for the same reason that the air swirls around a tornado center. As this air swirls in over the sea surface, it soaks up more and more water vapor. At the storm center, this new supply of water vapor gets pulled into the thunderhead updrafts, releasing still more energy as the water vapor condenses. This makes the updrafts raise faster, pulling in even larger amounts of air and water vapor from the storm's edges. And as the updrafts speed up, air swirls faster and…

    Hurricanes form near the equator over ocean waters. When they are near the United states they are called hurricanes. However when these storms are near places like Africa they are called cyclones. But it doesn’t matter what they are called, they all form and act the same way in different places. These storms require warm, moist air for fuel to start the storm. This is why these tropical storms only form in warm ocean water. These storms also need lots of wind and the atlantic ocean provides it.…

    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.…

    A hurricane is a large spiraling storm that produces winds of 119 kilometers per hour(74mph) or higher. These hurricanes are formed over warm ocean waters and can sometimes touch land. If the storm hit land it pushes a wall of water ashore called a storm surge. That put together with heavy rain fall is what creates flooding which is exactly what happened in the south due to hurricane Katrina. It was initially formed south of the Bahamas as a tropical depression but by the time it made its was to southern Florida, Katrina was a category one hurricane. By August 28 Katrina turned into a category five hurricane over the Gulf of Mexico but weakened to a categories four before hitting land along to the Louisiana-Mississippi border.…
