According to the National Oceanographic and Atmospheric Administration, a hurricane is a cyclonic storm that forms over tropical or subtropical waters and has sustained wind speeds of at least 74 mph, while a tsunami is a tidal wave created by an earthquake or underwater volcano. Hurricanes and tidal waves both can be extremely dangerous to those living near the coastline.Know More
Hurricanes occur when warm, calm ocean waters create convection air currents. As warm air rises, it creates a zone of low pressure, drawing in more air from outside areas. This motion carries moisture into the atmosphere, creating high level clouds and causing them to rotate. If the storm remains over warm water long enough, its winds may reach 74 miles per hour, at which point it becomes a hurricane. Hurricanes can push ocean water ahead of them, creating storm surges and dangerous waves, but these are markedly different from tsunamis.
A tsunami occurs when an earthquake or volcanic eruption creates a shockwave on the ocean's surface. This wave may only be a few feet high in the deep ocean, but its energy and height can increase as the storm travels into shallower water. Depending on the waveform, water may actually retreat from the shoreline before the tsunami strikes land for the first time.Learn more about Storms
According to the National Oceanic and Atmospheric Administration, a hurricane is an organized thunderstorm that occurs over water and has sustained winds that reach maximum speeds over 74 miles per hour. These storms originate over the Atlantic Basin, which includes the Atlantic Ocean, Gulf of Mexico and Caribbean Sea. When they reach land, they often cause structural damage and flooding.Full Answer >
The main difference between a hurricane and a tornado is that hurricanes form over warm water while tornados form over land. As of 2014, the largest tornado ever recorded was 2.5 miles wide, while hurricanes can measure over 1,000 miles wide.Full Answer >
Signs of a hurricane begin about 36 hours before landfall and include changes in wind patterns, cloud cover and precipitation. As the storm approaches, the intensity of these changes increases. Meteorologists are aware of these occurrences and emit public warnings when they begin.Full Answer >
The word "hurricane" comes from the Spanish "huracán," which in turn probably derived from the Native American Taino language of the Carib people. In Taino, Hurican is variously the god of evil or the god of the storm, and was imported himself from the Mayan god Hurakan.Full Answer >
