A typhoon is a tropical cyclone that occurs in the Northwest Pacific Ocean, explains the National Ocean Service. Typhoons, cyclones and hurricanes are all the same type of weather disturbance, but different names are used depending on the storm's location. Hurricanes occur in the Atlantic and Northeast Pacific Oceans, while cyclones occur in the South Pacific and Indian Oceans.Know More
A typhoon begins when warm, moist air rises from the ocean's surface while surrounding air rushes into the low-pressure area it leaves behind. The new air in the low pressure area also becomes warm and moist, explains NASA. This pattern of rising warm air and low pressure continues, creating the distinctive swirling wind characteristic of tropical cyclones. The rising warm air cools as it reaches higher elevations, and its evaporated water vapor condenses to form clouds. This combined system of clouds and cyclical winds continues to spin and grow.
NASA describes tropical cyclones as giant engines that use the ocean's warm air as fuel. An eye of low air pressure forms at the center of the storm system as it rotates faster. When the swirling winds reach a speed of 39 miles per hour, the storm is called a "tropical storm." At 74 miles per hour, the storm is officially a typhoon.Learn more in Storms
The term for a hurricane in Australia is tropical cyclone or just cyclone. Cyclones that form in the southern hemisphere by Australia rotate clockwise, while those that form north of the equator rotate counter-clockwise.Full Answer >
According to Geoscience Australia, the main source for the generation of a tropical cyclone is the abundance of warm water and favorable wind patterns that can persist for several days as the cyclone develops. Encyclopedia Britannica explains that warm, moisture-saturated air continues to rise through the center of the circulation as long as the air surrounding the core is cooler and heavier. The continuous vertical movement allows clouds to develop.Full Answer >
A hurricane is a tropical cyclone with sustained winds reaching speeds of at least 74 miles per hour, according to The Weather Channel. Hurricanes are classified on a scale of 1 to 5 using the scale Saffir-Simpson hurricane wind scale.Full Answer >
Damage from typhoons includes landslides and mudslides; heavy flooding; destruction of vehicles, buildings, roads and bridges; shipwrecks; power outages and human injury and death. Many people sustain injuries or die due to flying debris, collapsed buildings, flooding, mudslides and landslides, and storm surges.Full Answer >
