What is a Cyclone? A tropical cyclone is a low-pressure system which develops in the tropics and is sufficiently intense to produce sustained gale force winds of at least 63km/h.n other parts of the world they are called hurricanes or typhoons. Tropical cyclones can cause significant phenomena which can adversely, and sometimes favourably impact on communities and the environment. The most common features are destructive winds and heavy rainfall that can lead to flooding.

Contents: Cyclone vs Tornado Hurricanes and tornadoes are both stormy atmospheric systems that have the potential to cause destruction. They are caused by instability in atmospheric conditions. According to the region and severity of stormy conditions, hurricanes may also be referred to as typhoons or tropical cyclones.

- Many of the Eastern Pacific tropical cyclones originate, at least in part, from tropical waves coming off Cape Verde in Africa. Many of these waves traverse the entire Atlantic Ocean without generating storm development until after crossing Central America and entering the warm Eastern Pacific waters.

- Cyclones bringing clouds and precipitation. A cyclone is an area of low pressure around which the winds flow counterclockwise in the northern hemisphere. Since a cyclone is also known as a low pressure center, moving in any horizontal direction away from the Low will result in increasing pressure.Air converges into a low pressure center which causes air to rise. The rising motion may produce clouds and precipitation.ifferent precipitation types include rain and thunderstorms in the summer and fall seasons, to rain, thunderstorms, and even snow during the winter. A low is represented on a weather map by a red L. As a cyclone approaches, the likelihood of clouds and precipitation increases.

How do hurricanes form? Hurricanes are the most awesome, violent storms on Earth. People call these storms by other names, such as typhoons or cyclones, depending on where they occur.The scientific term for all these storms is tropical cyclone. Only tropical cyclones that form over the Atlantic Ocean or eastern Pacific Ocean are called hurricanes..Whatever they are called, tropical cyclones all form the same way. 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.nly tropical cyclones that form over the Atlantic Ocean or eastern Pacific Ocean are called hurricanes..

Cyclone A tropical cyclone is a storm system characterized by a low-pressure center and numerous thunderstorms that produce strong winds and flooding rain. A tropical cyclone feeds on heat released when moist air rises, resulting in condensation of water vapour contained in the moist air.esocyclones form as warm core cyclones over land, and can lead to tornado formation. Waterspouts can also form from mesocyclones, but more often develop from environments of high instability and low vertical wind shear.

Effects of tropical cyclones Outline of tropical cyclones. Tropical cyclones portal. The main effects of tropical cyclones include heavy rain, strong wind, large storm surges at landfall, and tornadoes. The destruction from a tropical cyclone depends mainly on its intensity, its size, and its location. Tropical cyclones act to remove forest canopy as well as change the landscape near coastal areas, by moving and reshaping sand dunes and causing extensive erosion along the coast. Even well inland, heavy rainfall can lead to mudslides and landslides in mountainous areas. Their eff

Natural Disasters These are normally quickly dispersed by the wind, but can collect in hollows. High concentrations can cause suffocation. This is the most common cause of death following a volcanic eruption. Tropical cyclones have been the cause of a number of natural disasters. They are storms with large low-pressure centres and numerous thunderstorms that produce high winds and heavy rain. Generally they are known as hurricanes, but in the northwest pacific region they are known as typhoons.

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.or this reason, coastal regions are particularly vulnerable to damage from a tropical cyclone as compared to inland regions. Heavy rains, however, can cause significant flooding inland, and storm surges can produce extensive coastal flooding up to 40 kilometres (25 mi) from the coastline.

Cyclones: facts and figures TROPICAL CYCLONES ARE intense, spinning storm systems, with low-pressure centres that can be vast in size. They form over warm oceans and can wreak havoc when they approach the shore.ow a cyclone forms. A tropical cyclone needs two main ingredients: a cluster of thunderstorms and a warm body of water – at least 27ºC – from which the storm gathers its energy. The warm, tropical ocean under a developing storm evaporates then condenses to form clouds, releasing heat throughout the process.

Tropical cyclone Without warm surface water, the storm cannot survive. A tropical cyclone can dissipate when it moves over waters significantly below 26.5 °C (79.7 °F). This will cause the storm to lose its tropical characteristics, such as a warm core with thunderstorms near the center, and become a remnant low-pressure area.

Tropical cyclones typically form over large bodies of relatively warm water.

Mid-latitude Cyclones, Tropical Climate and Cyclones How tropical cyclones develop and progress. This large rotating storm gets its energy from the evaporation of warm ocean water and the release of latent heat (warm, moist, rising air then begins to spiral upwards--rapidly rotating). As the storm system rotates faster and faster, an eye forms in the center.

Cyclones: facts and figures As the names suggests, tropical cyclones and hurricanes occur in the world's tropics. They require the difference in speed of rotation of the Earth at different latitudes to gather momentum as they spin, and they can form either side of the equator.ow a cyclone forms.

Cyclone Occluded fronts form late in the cyclone life cycle near the center of the cyclone and often wrap around the storm center. Tropical cyclogenesis describes the process of development of tropical cyclones. Tropical cyclones form due to latent heat driven by significant thunderstorm activity, and are warm core.

Tropical cyclone The majority (83%) of tropical cyclone damage is caused by severe hurricanes, category 3 or greater. However, category 3 or greater hurricanes only account for about one-fifth of cyclones that make landfall every year.

About Tropical Cyclones Structure of a cyclone. Radar image of cyclone. Tropical Cyclones are low pressure systems that form over warm tropical waters and have gale force winds (sustained winds of 63 km/h or greater and gusts in excess of 90 km/h) near the centre.

Why do cyclones occur? In meteorology, a cyclone is an area of low atmospheric pressure characterized by inward spiraling winds that rotate counter clockwise in the northern hemisphere and clockwise in the southern hemisphere of the Earth.s the cyclone builds up it begins to move. It is sustained by a steady flow of warm, moist air. The strongest winds and heaviest rains are found in the towering clouds which merge into a wall about 20-30 km from the storm's centre.

- This means that hurricanes, typhoons and tornadoes are all types of cyclones. What makes each cyclone unique is its location. Tornadoes occur over land, polar cyclones occur in polar regions and tropical cyclones occur over tropical oceans. What's not unique is how these storms develop.

About Tropical Cyclones The gale force winds can extend hundreds of kilometres from the cyclone centre. If the sustained winds around the centre reach 118 km/h (gusts in excess 165 km/h). then the system is called a severe tropical cyclone. These are referred to as hurricanes or typhoons in other countries.

Tropical cyclone develops in the Arabian Sea Tropical cyclone develops in the Arabian Sea. Rain affects southern Oman as cyclone tracks slowly towards the coast. A cyclone has developed in the Arabian Sea and is tracking towards the coast of Oman. Storms are fairly rare in the region, but they're not unheard of. If they do form in the Arabian Sea, they usually do so as the monsoon rains spread across the region, or when they retreat. This is why the majority of storms form in June or October. The strongest storm on record is Tropical Cyclone Gonu which struck in 2007.
