To sum it up, a cyclone is cloud/storm system that spins, and a hurricane is a tropical storm in the Atlantic Ocean. Also, Cyclone is the name for Hurricane type storms that hit Australia. Confusing, I know.

Dust devils are smaller and weaker than tornadoes, and arise from significantly different atmospheric conditions. They are caused by convection on hot, calm summer days. Air near the surface (ground) becomes much warmer than the air above, creating an updraft. Dust devils may rotate clockwise or counterclockwise, and their movement is slow and sporadic as they travel from one patch of warm air to another.

Well, a ditch is below ground leve by a few inches or a few feet.  A tornado has a lot of debris going hundreds of miles per hour.  The ditch gets you below the line of fire, so to speek.

In meteorology, a cyclone is an area of low atmospheric pressure characterised by inward spiraling winds that spin clockwise in the northern hemisphere of the Earth, or counterclockwise in the southern hemisphere. It is a generic description covering a wide variety of different meteorological phenomena such as tropical cyclones, Extratropical cyclones and tornadoes, thus is rarely used by meteorologists without a qualifying term.\n\nThe terms hurricane and typhoon are regionally specific names for a strong tropical cyclone—a non-frontal, synoptic-scale, warm-core low-pressure system with cyclonic surface wind circulation (Holland 1993). Specifically, hurricanes generally refer to such storms in the Atlantic Basin and the Pacific Ocean east of the International Date Line. Typhoons refer to the storms in the north Pacific west of the International Date Line. The typhoon term has also been applied to tropical cyclones in the South Pacific or Indian Ocean, but this is not considered correct usage today\n\nare same

Wikipedia has a good answer: http://en.wikipedia.org/wiki/Tropical_cyclone\n\nin addition:\n\nhttp://www.britannica.com/eb/article-67118\n\nFormation of tropical cyclones\n\nTropical cyclones represent still another example of sea-air interactions. These storm systems are known as hurricanes in the North Atlantic and eastern North Pacific and as typhoons in the western North Pacific. The winds of such systems revolve around a centre of low pressure in an anticlockwise direction in the Northern Hemisphere and in a clockwise direction in the Southern Hemisphere. The winds attain velocities in excess of 115 kilometres per hour, or 65 knots, in most cases. Tropical cyclones may last from a few hours to as long as two weeks, the average lifetime being six days.\n\nThe oceans provide the source of energy for tropical cyclones both by direct heat transfer from their surface (known as sensible heat) and by the evaporation of water. This water is subsequently condensed within a storm system, thereby releasing latent heat energy. When a tropical cyclone moves over land, this energy is severely depleted and the circulation of the winds is consequently weakened.\n\nSuch storms are truly phenomena of the tropical oceans. They originate in two distinct latitude zones, between 4° and 22° S and between 4° and 35° N. They are absent in the equatorial zone between 4° S and 4° N. Most tropical cyclones are spawned on the poleward side of the region known as the intertropical convergence zone (ITCZ).\n\nMore than two-thirds of observed tropical cyclones originate in the Northern Hemisphere, and roughly the same proportion occur in the Eastern Hemisphere. The North Pacific has more than one-third of all such storms, while the southeast Pacific and South Atlantic are normally devoid of them. Most northern hemispheric tropical cyclones occur between May and November, with peak periods in August and September. The majority of southern hemispheric cyclones occur between December and April, with peaks in January and February.\n\n\n---------------------------------------------\n\nTyphoon is a tropical cyclone located in the western north Pacific basin (between 100E and 180E in the northern hemisphere). The category of a typhoon is decided by the maximum sustained winds, but please note that the typhoon in Japanese standard and the typhoon in international standard is not the same. Finally, among tropical cyclones in the world, the typhoon is the most frequent and the strongest tropical cyclone (http://agora.ex.nii.ac.jp/digital-typhoon/help/world.html.en)\n------------------------------------------------------\n\nhttp://www.taiwanho.com/modules.php?op=modload&name=News&file=article&sid=205\n\nTyphoons (called hurricanes in the Atlantic and East Pacific, and cyclones in the Indian Ocean and around Australia) are the worlds most violent and destructive storm systems. Around 17 typhoons form annually in the West Pacific, of which around one third make landfall. They are giant whirlwinds, with air circulating around an area of low pressure, and high winds extending about 100km from the centre.\n\nMost typhoons form between 5-30 degrees latitude, and 110-180 degrees longitude. Typhoons that form in the east of this region can travel for long distances without being affected by landmasses. This gives them plenty of time to build up their strength. Hence, the very strong and long lasting supertyphoons tend to form closer to the date line. Sea surface temperatures in the Nino 4 region (5S-5N, 160E-150W) affect the longitude at which typhoons tend to form. Warm sea surface temperatures in this region result in more typhoons forming closer to the date line.\n\nSome prerequisites for typhoon formation are listed below:\n\n1. Sea surface temperatures greater than 26C to a depth of 60m. This provides the moisture for the thunderstorm activity in the storm.\n\n2. A large enough drop in temperature with height so that the atmosphere is conditionally unstable to

yes hurricane winds are regulated by the Saffir-Simpson scale of hurricane intensity.  which has five levels of intensity ranging from category 1-5 \n\ncategory 1 75-95 sustained wind\ncategory 2 96-110 sustained wind\ncategory 3 111-130 sustained wind\ncategory 4 131-155 sustained wind\ncategory 5 156+ sustained wind\n\nGusts are also associated with huricanes and can reach about 215 mph in category 5 hurricanes.\n\nthe strength of a hurricane is dependant on the lowest barometric presure inside of the storm.  The strongest hurrican of record is hurricane wilma from the 2005 hurricane season, when it reached a barometric pressure of 882 mb.

Large scale flows depend on the Coriolis effect, which make the motion turn differently in each hemisphere. Therefore cyclones, hurricanes (though they are rare in southern hemisphere) and such events turn clockwise in the southern hemisphere and counterclockwise in the northern hemisphere. As the spatial scale diminishes, the Coriolis effect loses importance. For tornadoes, for instance, it is still sufficient to make 98% of them to turn clockwise in the southern hemisphere and counterclockwise in the northern hemisphere. But, in 2% of the cases they turn differently.\nDust devils are small enough so that they can turn either way, independently of hemisphere.\nOf course, the water flowing down your sink is a very small-scale process. Coriolis effect makes no difference in that case.\nTherefore, it can go either way, both in Australia and in North America, depending only on the sink geometry.

Tornado is the most violent of all storms. A tornado, sometimes called a twister, consists of a rapidly rotating column of air that forms under a thundercloud or a developing thundercloud. Tornado winds swirl at speeds that may exceed 300 miles (480 kilometers) per hour. A powerful tornado can lift cattle, automobiles, and even mobile homes into the air and destroy almost everything in its path. Fortunately, most tornadoes are relatively weak, and only a few are devastating. \nScientists use the word cyclone to refer to all spiral-shaped windstorms that circulate in a counterclockwise direction in the Northern Hemisphere or in a clockwise direction in the Southern Hemisphere. The term cyclone comes from the Greek word for circle. Cyclones come in many sizes. Among the largest such storms are hurricanes and typhoons, which may reach 250 miles (400 kilometers) across. \nMost tornadoes are small, intense cyclones. On rare occasions, the winds whirl in the direction opposite that of a cyclone--for example, clockwise in the Northern Hemisphere. \nMost tornadoes have damage paths less than 1,600 feet (500 meters) wide, move at less than 35 miles (55 kilometers) per hour, and last only a few minutes. Extremely destructive twisters may reach 1 mile (1.6 kilometers) in diameter, travel at 60 miles (100 kilometers) per hour, and blow for more than an hour. \nThe United States has the highest incidence of tornadoes in the world. Most of these storms occur in a belt known as Tornado Alley that stretches across the Midwestern and Southern states, especially Texas, Oklahoma, Kansas, Nebraska, and Iowa. However, tornadoes also strike many other parts of the world. Australia ranks second to the United States in number of twisters, and many damaging tornadoes strike Bangladesh. Tornadoes occur most often during the spring and early summer in the late afternoon and early evening. \nA tornado over a body of water is called a waterspout. Waterspouts occur frequently in summer over the Florida Keys. Waterspouts also form elsewhere in the Gulf, along the Atlantic and Pacific coasts, over the Great Lakes, and even over the Great Salt Lake in Utah. \nThe story of a tornado. The majority of tornadoes develop from severe thunderstorms. A hurricane, when it makes landfall, can also generate tornadoes. \nThe most damaging tornadoes form in large, powerful thunderstorms called supercells. For a supercell to form, and perhaps spawn a tornado, several conditions must exist. There must be an adequate supply of moisture to feed the storm. In Tornado Alley, air from the Gulf of Mexico provides the moisture. There must be a layer of warm, moist air near the ground and a layer of much cooler air above. Often, a front (the boundary between two air masses at different temperatures) powers an upward flow of warm air. As the warm air rises, it begins to cool, and the moisture it holds condenses into raindrops. The air stops rising at high levels and spreads sideways to form a characteristic anvil-shaped storm cloud. \nFor a supercell to develop, the winds at higher elevations must differ markedly from those at lower levels in speed, direction, or both. Such a large difference in wind speed or direction is called wind shear. Wind shear makes the column of rising air begin to rotate, forming a broad, horizontal tube of swirling air. As the storm continues, this tube turns on its end, producing a rotating column of air called a mesocyclone. Studies show that most supercells containing mesocyclones eventually produce tornadoes. \nA low, dark, heavy cloud called a wall cloud forms underneath the mesocyclone. Tornado funnels develop out of the wall cloud. \nThe first sign of an approaching tornado may be light rain, followed by heavier rain, then rain mixed with hail. The hailstones may grow to the size of golf balls or even baseballs. After the hail ends, a tornado may strike. In most tornadoes, a funnel-shaped cloud forms and descends from the wall cloud until it touche

Both Hurricanes and Typhoons are tropical cyclones, though Hurricanes are Atlantic Ocean events while Typhoons are found in the Pacific.
