| Trends in tropical cyclone activity in the Australian region show that the total number of cyclones has decreased in recent decades. |
|
| In 1978, a tropical cyclone, with destructive winds and huge waves, washed away large sections of the jetty near the shore. |
|
| The intensity and stage of development of a tropical cyclone depends on its wind strength and says nothing about the rainfall. |
|
| Mitigation may only go so far, and there may still be specific things to do when a tropical cyclone hits. |
|
| This may sometimes be associated with a tropical cyclone or a monsoon low. |
|
| Large vertical wind shear disrupts a growing disturbance and can prevent a tropical cyclone from forming. |
|
| A tropical cyclone is a storm system that has a low-pressure centre and thunderstorms that produce strong winds and flooding rain. |
|
| Very often the rainfall with post-tropical systems is enhanced by a frontal system already in the vicinity when the tropical cyclone arrives. |
|
| Elsewhere this is called a tropical cyclone, severe tropical cyclone, or severe cyclonic storm. |
|
| While these conditions are needed to create a tropical cyclone, it does not mean that they are enough to create one. |
|
| When the motion of a tropical cyclone changes from westward to eastward, the tropical cyclone is said to recurve. |
|
| This is when the interesting physics of tropical cyclone formation really begins. |
|
| The first one is the former tropical cyclone Tomas, which lies ahead of Safran. |
|
| The main objective of the Panel is to promote measures to improve tropical cyclone warning systems in the Bay of Bengal and the Arabian Sea. |
|
| The high moisture content of the tropical cyclone gets drawn into this frontal system. |
|
| The eventual tropical cyclone that forms will be referred to as a warm-air or warm-core storm because of the process just described. |
|
| Areas in their path can receive a year's worth of rainfall from a tropical cyclone passage. |
|
| Coastal regions are particularly vulnerable to the impact of a tropical cyclone, compared to inland regions. |
|
| When the primary eyewall weakens, the tropical cyclone weakens temporarily. |
|
| The primary rotating flow in a tropical cyclone results from the conservation of angular momentum by the secondary circulation. |
|
|
|
| This fact leads to the existence of a theoretical upper bound on the strongest wind speed that a tropical cyclone can attain. |
|
| This can strengthen the resultant system, although it may no longer be a tropical cyclone. |
|
| Another method of measuring surge is by the deployment of pressure transducers along the coastline just ahead of an approaching tropical cyclone. |
|
| The most active place on Earth for tropical cyclone activity lies northeast of the Philippines and south of Japan. |
|
| It comprises 10 identical new 55-metre high wind turbines designed to be winched to the ground when required for maintenance or to avoid wind damage in the event of a tropical cyclone. |
|
| As well, while it is not required, a high-pressure area located at the top of the troposphere above the storm or growing disturbance can greatly help a tropical cyclone to form. |
|
| This motion of surface air is the wind we feel in a tropical cyclone. |
|
| This is important because the weather and impacts from a transitioning tropical cyclone are different than those from the purely tropical cyclone. |
|
| One impact of climate change is an increase in tropical cyclone. |
|
| Barely a fortnight after 120,000 people were displaced in floods caused by torrential rains, the country has now suffered the effects of a tropical cyclone. |
|
| However, similar to the reasoning behind the shift in American fatality statistics, this doesn't mean that it is any safer now at sea during a tropical cyclone than it used to be. |
|
| However, researchers believe that a tropical cyclone slamming into the Gulf isn't quite as unlikely as you may think. |
|
| We're making this decision now because we don't know the exact track of this tropical cyclone yet. |
|
| This chapter describes variations in tropical cyclone activity over the western North Pacific on time scales from interdecadal to intraseasonal. |
|
| An example of a tropical cyclone in recurvature was Typhoon Ioke in 2006, which took a similar trajectory. |
|
| November is the only month in which all the tropical cyclone basins are active. |
|
| The Pacific hosts the two most active tropical cyclone basins, which are the northwestern Pacific and the eastern Pacific. |
|
| A tropical cyclone can cease to have tropical characteristics in several different ways. |
|
| There is a chance a tropical cyclone could regenerate if it managed to get back over open warm water, such as with Hurricane Ivan. |
|
| Other approaches have been suggested over time, including cooling the water under a tropical cyclone by towing icebergs into the tropical oceans. |
|
|
|
| The broad rotation of a landfalling tropical cyclone, and vertical wind shear at its periphery, spawns tornadoes. |
|
| A tropical cyclone does not need to be particularly strong to cause memorable damage, primarily if the deaths are from rainfall or mudslides. |
|
| The report concluded the observed increase in tropical cyclone intensity is larger than climate models predict. |
|
| From an operational standpoint, a tropical cyclone is usually not considered to become subtropical during its extratropical transition. |
|
| On 20 February 2016, Fiji was hit by the full force of Cyclone Winston, the only Category 5 tropical cyclone to make landfall in the nation. |
|
| November is the only month that activity in all the tropical cyclone basins is possible. |
|
| Another factor is rapid cooling with height, which allows the release of the heat of condensation that powers a tropical cyclone. |
|
| Lastly, a formative tropical cyclone needs a preexisting system of disturbed weather. |
|
| Additionally, tropical cyclone motion can be influenced by transient weather systems, such as extratropical cyclones. |
|
| The landfall of a tropical cyclone occurs when a storm's surface center moves over a coastline. |
|
| The passage of a tropical cyclone over the ocean causes the upper layers of the ocean to cool substantially, which can influence subsequent cyclone development. |
|
| The trend observed by Kossin and his colleagues is particularly important given the devastating loss of life and property that can follow in the wake of a tropical cyclone. |
|
| Climate models suggest that a warm phase of the AMO strengthens the summer rainfall over India and Sahel and the North Atlantic tropical cyclone activity. |
|
| Bagyo is the local term for a tropical cyclone in the Philippines. |
|
| Worldwide, tropical cyclone activity peaks in late summer, when the difference between temperatures aloft and sea surface temperatures is the greatest. |
|
| These kinds of cyclones, known as extratropical cyclones and subtropical cyclones, can be stages a tropical cyclone passes through during its formation or dissipation. |
|
| A subtropical cyclone is a weather system that has some characteristics of a tropical cyclone and some characteristics of an extratropical cyclone. |
|
| At the center of a mature tropical cyclone, air sinks rather than rises. |
|
| Today, it is known that silver iodide seeding is not likely to have an effect because the amount of supercooled water in the rainbands of a tropical cyclone is too low. |
