How the cyclones are form, how can we predict that?

Actually, cyclones ARE another name for hurricanes - I post this directly, not changing the context one bit.\n\nIn meteorology, a cyclone is the rotation of a volume of air about an area of low atmospheric pressure. Cyclones are responsible for a wide variety of different meteorological phenomena such as tropical cyclones and tornadoes. Because of this, most weather forecasters avoid using the term cyclone without a qualifying term.\n\nTropical cyclones (also known as tropical storms, hurricanes and typhoons) are cyclones which form over warm (generally tropical) ocean waters and draw their energy from evaporation and condensation. They are characterized by a strong area of low pressure at the surface and an area of higher pressure aloft. Tropical cyclones are associated with strong thunderstorms, high winds, and flooding.\n\nIn North America, tornadoes are sometimes described as cyclones because they involve powerful winds around a low-pressure vortex. However, they differ from other cyclones by their very local nature; most cyclones are massive storms, while tornados are comparatively small but extremely powerful. Tornadoes occur on too local a scale for the Coriolis effect to determine the direction of rotation; for this reason tornado winds sometimes flow anticyclonically, or opposite the direction dictated by the Coriolis effect.

Hurricanes are strong wind storms, which are cyclonic in nature. This means that they revolve around a central point, which is known as an ‘eye’. The eye is the calmest part in the storm, while the winds raging around the storm have reached a speed of 119 km an hour! The winds rotate in an anti-clockwise direction in the northern hemisphere, and in a clockwise direction in the southern hemisphere. \n\n\nHow are hurricanes formed? \n\nHurricanes are formed in tropical, ocean areas. The warm air above the ocean begins to rise, and as it rises, it condenses and forms clouds and rain droplets. The process of condensation always results in the release of heat. So when the heated air rises and releases heat during condensation, the surrounding air also becomes warm. This warm air rises further, and then gets blown away by the high altitude winds, and cold air is pushed down to the ocean. The cold air then becomes warm because of the warmth of the ocean, and rises up again and is blown away. In addition, converging winds over the ocean (winds that run into each other) also push the ocean air upwards. Since the ocean air is in any case rising when they are warmed, the converging winds make it rise even faster. Thus, due to these phenomena, the movement of air increasingly becomes more and more rapid. \n\n\nWhat are tornadoes? \n\nFar more violent than hurricanes are tornadoes. Winds surrounding tornadoes often reach speeds of 100 miles an hour, and have even reached speeds of 300 miles an hour. \n\n\nHow are tornadoes formed? \n\nTornadoes are usually formed from thunderstorms and can be defined as a violent column of air extending from the base of a thundercloud to the ground. To put it simply, thunderstorms that rage in the sky ‘drop’ what appears to be a rope, but is actually a gust of wind moving in a circular direction. When this ‘rope’ touches the ground, it wreaks havoc. \n\nTornadoes are formed in a similar manner as hurricanes. Warm, moist air rises up and condenses, releasing heat and forming a thundercloud and rain. (Tornadoes are thus often accompanied by rain, and can cause flooding.) This continuous rise of air upwards is called an ‘updraft’, and a low pressure area is created in the center. High pressure cold winds are then sucked inwards, and the colliding forces causes the thunderstorm to rage. \n\nThese clouds are often green in colour, and at times the sky too turns green – a phenomenon that scientists still don’t have an explanation for. Hurricanes and tornadoes are similar to the extent that they both have a cyclonic movement, which means that they rotate around an eye. A tornado’s movement, as we have seen, is far swifter and more centered. \n\n\nHow are tornadoes ranked? \n\nTornadoes are ranked on a six-tiered “Fujita Scale”. A rank of F0 means that the tornado is weak and has caused a minimal of damage, while a rank of F6 means that the tornado was severe and has caused many deaths and damage to property. The vortex of a tornado is a dangerous place to be because here is where there is maximum rain and hail.

The eye is possibly the most recognizable feature of tropical cyclones. In strong tropical cyclones, the eye is a circular area of light winds and clear skies, surrounded on all sides by a towering vertical wall of thunderstorms, known as the eyewall. In weaker tropical cyclones, the eye is less defined, and can be covered by the central dense overcast, which is the area of high, thick clouds which show up brightly on satellite pictures. Rain may even fall heavily in the eye of a disorganized storm. In all storms, however, the eye is the location of the storm's minimum barometric pressure: the area where the atmospheric pressure at sea level is the lowest.[1][2]

I would say on the eastern side.  You're still going to be experiencing the most Positive Vorticity on that side.  Though the clouds should be mostly mid and high level clouds.  \n\nAs for formation:\n\nFrom the American Meterological Society glossary:\nA sequence of events by which a warm high or cold low, originally within the westerlies, becomes displaced either poleward (cut-off high) or equatorward (cut-off low) out of the westerly current. \nThis process is evident at very high levels in the atmosphere; it frequently produces, or is part of the production of, a blocking situation.

The Scientists don't know yet, so if they don't know we don't know. We can only guess to what it is.\n\n\nScientists said it was unclear whether Saturn's storm was a water-driven system.\n\nIt differs from Earth hurricanes in part because it remains stuck at the pole rather than drifting as such storms do on this planet and because it did not form over a liquid water ocean, with Saturn being a gaseous planet, NASA said.\n\n"It looks like a hurricane, but it doesn't behave like a hurricane," Andrew Ingersoll, a member of Cassini's imaging team at the California Institute of Technology in Pasadena, said in a statement. "Whatever it is, we're going to focus on the eye of this storm and find out why it's there."\n\nFlasar said scientists have more work ahead to understand the Saturn storm.\n\n"I'm hoping that as we puzzle over it, it will become even more exciting as we start to connect the dots in our brains. But right now, the wheels are a little creaky," Flasar said. "We're all arguing with each other about what it might or might not be."

Analysts looks for groups of storms and evidence of a low-level circulation using satellite images - especially near any preexisting Lows or easterly waves they've been tracking. Several things can be used to help them determine the strength of the circulation:\n\n* Surface and radiosonde data that happen to be nearby (not often much over the ocean).\n\n* The Dvorak techinique is used to estimate the storm's strength using satellite images alone.\n\n* Scatterometer winds using satellites.\n\n* Reconnaissance flights and dropsondes used in them (normally after a storm has formed and is named).\n\nOnce the maximum sustained wind is measured (preferably) or estimated at 39 mph or greater, the tropical cyclone is named.

Extratropical cyclones- storms that have frontal interactions, sometimes called midlatitude cyclones\nTropical cyclones- hurricanes, tropical storms; these have no frontal zones and are usually found in "source regions" during tropical season.\nCyclones and disturbances are not limited to the surface and can occur at any level in the atmosphere.

The difference is where they happen.  The storms are called hurricanes in the Caribbean, the Atlantic and the eastern Pacific.  They are called typhoons in the western Pacific, and they are called cyclones in the Indian Ocean, but the physics of the storms are the same.  I believe the direction of rotation may be different, depending on whether they are in the northern hemisphere or the southern hemisphere.\n\nA hurricane, typhoon, or cyclone is any mass of air that spirals around a low pressure center. It is an organized collection of thunderstorms embedded in a swirling mass of air.\n\nAt the center of the spiral is the eye, a vertical tube of clear skies and calm winds; the more intense the storm, the smaller the eye.\n\nAlthough the main upwards flow of air is around the eye, the entire air mass is unstable. Spiraling rows of thunderstorms with relatively clear areas between them extend outwards for up to two thousand miles from the center, gradually diminishing in intensity.

Anytime you ask statistical question such as this, you need data to figure out any kind of estimate.  One of the problems with any type of weather forecasting this far into the future is that there is not enough data to calculate, and hence, predict what will happen on a particular day in a particular area far months into the future.  \n\nAccording to the National Weather Service webpage for your area: "Hurricanes are products of an interaction between both the ocean and the atmosphere.  Fueled by energy from the warm ocean waters, they can be steered by the easterly trade winds, as well as the temperate westerlies.  Some hurricanes, especially strong ones, are even able to alter the environment that steers them.  This is a major reason why it can sometimes be very difficult to predict where a particular hurricane will track."\n\nUnfortunately, you are going to have to wait until Labor Day Weekend, 2006 to get your answer, but you can contact the Tampa Bay Weather Service Office if you would like to talk to a professional.

Well, first off it's probably in the tropics...  ;)\n\nI cut and pasted this part (sorry, feeling lazy):\n\n"In meteorology, a tropical cyclone is a storm system with a closed circulation around a center of low pressure, fueled by the heat released when moist air rises and condenses. The name underscores their origin in the tropics and their cyclonic nature. They are distinguished from other cyclonic storms such as nor'easters and polar lows by the heat mechanism that fuels them, which makes them "warm core" storm systems.\n\nDepending on their strength and location, a tropical cyclone can be called a tropical depression, tropical storm, hurricane, or typhoon, among other names.\n\nTropical cyclones can produce extremely high winds, tornadoes, torrential rain (leading to mudslides and flash floods), and drive storm surge onto coastal areas. Though the effects on populations and ships can be catastrophic, tropical cyclones have been known to relieve drought conditions. They carry heat away from the tropics, an important mechanism of the global atmospheric circulation that maintains equilibrium in the environment." (wikipedia - see below)

As much as I hate to contradict others, the East and West explanation is inaccurate. Hurricanes are in the Northern Hemisphere, while cyclones and typhoons are in the Southern Hemisphere. Another difference, which is caused by their location, is the direction in which they spin. The rotation of  the Earth causes hurricanes to spin counterclockwise, while cyclones go clockwise.

Centers of a cyclone is a low-pressure region. Near the center of the cyclone the pressure gradient force, from high- to low-pressure regions, and the Coriolis force must be in an approximate balance (or else the cyclone would collapse in on itself under the pressure gradient). The wind flow around a large cyclone is counterclockwise in the northern hemisphere, and clockwise in the southern hemisphere, due to the Coriolis effect. Large anticyclonic storms are extremely rare on Earth, though Jupiter's Great Red Spot storm is anticyclonic.

Excellent question!!  And one which is never fully explained on any weather forecast/ weather station....\n\nWeather conditions are controlled by the air currents over the Pacific Ocean, for the most part, first of all.  You can watch typhoons or Pacific hurricanes travel westward, until they reach a landmass, then these low-pressure storms will turn North-Northeast and follow the jet stream, until they are turned South-southeast ward, and affect the U.S. northwest states, Washington, Oregon, California.....\n \nThese extra-tropical storms keep their strength as they travel around the path of the Northern jetstream, droping rain and producing winds not unlike a hurricane, as they follow the jetstream paths around the world.  \n\nAfter these storms, these Pineapple Expresses, have traversed the United States, they again gain strength over the Northern Atlantic ocean, and then let go of the precipatation over Britian and Europe, where the Original storm dies.....\n\nAgain, excellent question.  Hope this enlightens you!!

A lot of Science and Maths goes behind such predictions. Data collected from satellites, weather balloons, planes and land based instruments is analysed for numerical patterns. These patterns are then processed and compared with findings of a particular time span when a certain amount of known rainfall occurred. In the end a forecast is issued.\n\nNowadays, the job is done by Super Computers but there still remains a large room for errors.

Hurricanes, it is truly amazing they way they form and have an eye and are just so powerful!

A large storm pulls energy from as far around as it can reach. Therefore if the storm moving is pulling all the heat and moisture out of the air around it, then there is a void of mayhem, a calm, before the actual storm throws back all that was there to begin with.
