What is a cyclone? A cyclone is a large-scale low pressure system characterized by a cyclonic circulation (counterclockwise in the northern hemisphere and clockwise in the southern) about a definite center where pressure is lowest. Air spirals toward the center of a cyclone, rises, and then diverges at upper levels.hus, a cyclone rotate … s clockwise in the Southern Hemisphere and counterclockwise in the Northern Hemisphere. In meteorology the term cyclone is reserved for circulation systems with horizontal dimensions of hundreds (tropical cyclones) or thousands (extratropical cyclones) of kilometers.

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. 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.

- Antarctica as a whole is the coldest continent on the Earth. The continent covers over 14 million sq km making it 1.5 times the size of the USA.Antartica occupies approximately 9% of the world's land surface.ntarctica has six months of daylight and six months of darkness. In mid-summer, near the south pole, there is 24 hours of sunlight every day. In winter, six months of darkness ensue, and the continent triples in size by converting the surrounding sea into ice.

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. 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.

upwelling Trade winds at the Equator blow surface water both north and south, allowing upwelling of deeper water. The wind patterns generated during slow-moving cyclones can also blow surface water aside, causing upwelling directly beneath the eye of the cyclone. The colder water eventually helps to weaken the cyclone.

- A cyclone is a storm or system of winds that rotates around a center of low atmospheric pressure. An anticyclone is a system of winds that rotates around a center of high atmospheric pressure. Distinctive weather patterns tend to be associated with both cyclones and anticyclones.

Low Pressure Systems Away from areas of high pressure and into areas of low pressure... The Coriolis Force also adds rotation to the movement of air. In the Northern Hemisphere, air moves clockwise around a High and counter-clockwise around a Low. Air moves into a Low pressure system. It pushes any air that was there up.

Tropical cyclone A hurricane or typhoon (sometimes simply referred to as a tropical cyclone, as opposed to a depression or storm) is a system with sustained winds of at least 34 m/s (66 kn; 76 mph; 120 km/h). A cyclone of this intensity tends to develop an eye, an area of relative calm (and lowest atmospheric pressure) at the center of circulation.

Cyclone There are a number of structural characteristics common to all cyclones. A cyclone is a low-pressure area. A cyclone's center (often known in a mature tropical cyclone as the eye), is the area of lowest atmospheric pressure in the region.ropical cyclones form due to latent heat driven by significant thunderstorm activity, and are warm core. Cyclones can transition between extratropical, subtropical, and tropical phases under the right conditions.

cyclone A large-scale system of winds that spiral in toward a region of low atmospheric pressure. A cyclone's rotational direction is opposite to that of an anticyclone. In the Northern hemisphere, a cyclone rotates counterclockwise; in the Southern hemisphere, clockwise. Because low-pressure systems generally produce clouds and precipitation, cyclones are often simply referred to as storms. An extratropical cyclone is one that forms outside the tropics at middle or high latitudes.

- Winds in the eye wall itself have the highest velocity and this zone can extend outward from the center to distances of 16 to 40 km. Hurricane force winds (winds with velocities greater than 119 km/hr) can extend out to 120 km from the center of the storm. The largest tropical cyclone recorded, Typhoon Tip, had tropical storm force winds (39 mph/62 km/hr) which extended out for 1100 km in radius in the Northwest Pacific in 1979. Hurricane Katrina, in 2005, was a large hurricane with tropical storm force winds extending outward from the eye about 320 km.

Does the rotation of the Earth affect toilets and baseball games? With a high-pressure system, air gets forced outward and the Earth's eastward spin creates a clockwise flow. In the Southern Hemisphere, the opposite takes place: Wind around low-pressure systems circles clockwise while wind around high-pressure systems circles counterclockwise.

About Tropical Cyclones 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.hese are referred to as hurricanes or typhoons in other countries. The circular eye or centre of a tropical cyclone is an area characterised by light winds and often by clear skies. Eye diameters are typically 40 km but can range from under 10 km to over 100 km.

High School Earth Science/Air Movement Wind is caused by air flowing from high pressure to low pressure. The Earth’s rotation prevents that flow from being direct, but deflects it side to side(right in the Northern Hemisphere and left in the Southern), so wind flows around the high and low pressure areas. This movement around is important for very large and long-lived pressure systems.

Play Whirlwind Disaster! Tropical cyclones are like engines that require warm, moist air as fuel. So the first ingredient needed for a tropical cyclone is warm ocean water. That is why tropical cyclones form only in tropical regions where the ocean is at least 80 degrees F for at least the top 50 meters (about 165 feet) below the surface.

Coriolis force 1 If a low-pressure area forms in the atmosphere, air flows towards this region, but will be. deflected perpendicular to its velocity by the Coriolis force (see next page). Instead of flowing. straight towards the low pressure area, the air ends up circulating around it. This pattern of air. flow is called a cyclone.

- Both are classed … as tropical cyclones wind winds of at least 74 mph. A cyclone is virtually any low pressure system, this includes hurricanes and typhoons, as well as other, much less severe weather systems. Cyclones are typically several hundred miles wide.he average tornado is 50 yards (150 feet) wide some tornadoes are under 10 yards (30 feet) wide. The wides tornado ever recorded was 2.5 miles wide. Hurricanes and typhoons are essentially the same thing, the only difference is where they occur.

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. The circular eye or centre of a tropical cyclone is an area characterised by light winds and often by clear skies. Eye diameters are typically 40 km but can range from under 10 km to over 100 km.

High and Low Pressure Wind Movement As I understand it, wind starts from air moving from high pressure areas to low pressure areas and air pressure is measured in millibars. Here's where I'm mixed up: I've been looking at charts of low pressure areas (smaller circles with lower millibar levels) moving under Africa towards Australia.he tendency for air to move from an area of high pressure to an area of low pressure is called the pressure gradient force (PGF). Now if the earth didn't rotate about its axis the wind would flow directly from high to low, such as the below.
