Aside from the name, not much. Both are severe tropical systems that have wind speeds greater than 74 mph. \n\nThey are called "hurricanes" in the Atlantic Ocean, Caribbean and eastern Pacific Ocean. But once your go west across the International Dateline and into the western Pacific Ocean, they're called typhoons. And of course, the Australians, who have colorful names for just about everything, have their own term for hurricanes: "willy-willys." \n\nTyphoons generally tend to be stronger than hurricanes, but only because there's warmer water in the western Pacific and are better conditions for storm development. And they've been known to affect Seattle: Some of our strongest windstorms ever recorded were remnants of a typhoon in the western Pacific.

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)

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.

Actually this is true.  The Hurricane Hunters, an air wing of the National Oceanographic and Atmospheric Administration routinely flies P-3 Orion and C-130 Hercules Aircraft into the eyes of hurricanes to do weather observations.  They also commonly report seeing birds in the eyes of hurricanes.

Well some obvious differences are:\n\nTornadoes form over land. Hurricanes form over water.\n\nHurricanes are huge, tens to hundreds of miles across.\nTornadoes are rarely more than a hundred yards in diameter.\n\nHurricanes linger in the ocean for days or even weeks.\nTornadoes are usually gone in under an hour.\n\nHurricanes are rated by their wind speed: Category 1 70 mph winds to category 5 180 mph winds.\n\nTornadoes are rated by size (I think), F1 through F5.\n\nTry any web site having to do with weather or meteorology for lots more info.\n\nThe National Weather Service, The Weather Channel, etc.

National Geografic website has a lot of information about it. \nIf you go to the linlk provided and then to the section of Natural Forces, you will find a lot of material to support your research. \n\nSecond link is about simulate and understand these events, explaning how it works at all their levels. You can find it to Earthquake, Hurricane, etc. I've putted the link to Vulcanoes\n\nGood luck

Hurricanes are intense low pressure  areas that form over warm ocean waters in the summer and early fall. Their source of energy is water vapor  which is evaporated from the ocean surface. Water vapor is the "fuel" for the hurricanes because it releases the "latent heat of condensation" when it condenses to form clouds and rain, warming the surrounding air. (This heat energy was absorbed by the water vapor when it was evaporated from the warm ocean surface, cooling the ocean in the process.) Usually, the heat released in this way in tropical thunderstorms is carried away by wind shear, which blows the top off the thunderstorms. But when there is little wind shear, this heat can build up, causing low pressure to form. The low pressure causes wind to begin to spiral inward toward the center of the low. These winds help to evaporate even more water vapor from the ocean, spiraling inward toward the center, feeding more showers and thunderstorms, and warming the upper atmosphere still more. The showers and thunderstorms where all of this energy is released are usually organized into bands (sometimes called "rainbands" or "feeder bands"), as well as into an "eyewall" encircling the center of the storm. The eyewall is where the strongest winds occur, which encircle the warmest air, in the eye of the hurricane. This warmth in the eye is produced by sinking air, which sinks in response to rising air in the thunderstorms. The winds diminish rapidly moving from the eyewall to the inside of the relatively cloud-free eye, where calm winds can exist.\nhurricane eyes seen from the Space Shuttle and from aircraft\nHurricane intensity is based upon the highest sustained (1 minute average) wind speed the hurricane is producing. The "Saffir-Simpson" scale rates hurricane strength in this way from Category 1 to Category 5. These categories were chosen based upon the amount of damage that each category can produce.\nIntensity Wind Speed Damage\nCategory 1 74- 95 mph MINIMAL: tree branches, shrubs, unanchored mobile homes\nCategory 2 96-110 mph MODERATE: mobile homes, poorly constructed buildings, some trees down\nCategory 3 111-130 mph EXTENSIVE: small buildings damaged, large trees down, mobile homes destroyed\nCategory 4 131-155 mph EXTREME: outer walls damaged, roof failure on small buildings, extensive damage to doors and windows, mobile homes destroyed\nCategory 5 >155 mph CATASTROPHIC: complete roof failure on many buildings, some buildings destroyed, severe window and door damage, mobile homes destroyed\nIn low-lying areas, much of the damage from hurricanes can be from the "storm surge", in which water being blown onshore by the high winds rises rapidly. The storm surge can destroy the lower floors of some buildings, or even destroy the foundations of residences causing the homes to wash away. The storm surge can also trap residents from evacuating along low-lying escape routes.\n\nHurricanes almost always travel poleward at the end of their life cycle, helping to transport excess heat out of the tropics toward higher latitudes. They gradually die as they move over cooler waters, which do not have the heat energy necessary to evaporate sufficent water vapor into the atmosphere to fuel the hurricane. If the hurricane crosses over to land, the heat source is removed entirely. With the removal of the energy source, and the greater surface friction of the land's terrain and vegetation, the hurricane's winds rapidly decrease.

For speed of a hurricane they use the Saffir-Simpson Scale. See link one for more information on hurricane speeds. For picture of damage for each level, see link two. I found no information on the height of a hurricane.

This short-term increase is more so associated with ocean temperatures and their affects on hurricane formation. The tropical Atlantic has been warm, and ocean temperatures there and in the equatorial Pacific have provided a favorable environment for them - wind shear in the tropics tending to be weak.\n\nGlobal warming most likely is contributing to the longer-term increase (e.g., many more storms than normal the past decade).

Typhoons and hurricanes are the same type of storm - a tropical cyclone - just in different parts of the world.\n\nHowever... typhoons - which affect the western Pacific ocean - tend to be stronger than Atlantic hurricanes because the waters are warmer.

In all reality, Hurricanes are thunderstorms that have gotten out of hand. The following website explains in further detail. It may be slow to load, but it's a great informative site!
