According to the Weather Channel, the primary methods of tracking hurricanes include satellite imaging, Doppler radar and aircraft overflights. In addition, weather stations that measure wind speed and direction as well as rainfall, and report that data wirelessly, can prove extremely useful for determining a hurricane's effects. Most of these stations are placed on land, but buoys throughout the hurricane-producing regions of the ocean provide an early warning system.Know More
Often, the first warning of a hurricane comes from satellite data. Satellites can measure water and air temperature as well as cloud density and movement, and give the first real sign of the rotation that signifies a newly born tropical storm. Once a storm begins to approach land, Air Force and NOAA pilots make reconnaissance flights into and above the developing storm. These planes often drop sensor gear into the storm to measure wind speeds at various altitudes, providing a three-dimensional picture of the storm's power.
When the storm approaches the coast, land-based radar and weather stations can begin providing more comprehensive data about the storm's movement and its effects, allowing forecasters to warn those in the hurricane's path to evacuate if necessary. Computer models are also invaluable tools for determining the probable movement of a storm 24 to 48 hours ahead of time, providing as much warning as possible.Learn more about Storms
According to the US Department of Energy, the main equipment used to predict tornadoes is the Doppler radar system. Doppler radar can measure wind velocity, direction of the wind inside the storm and the predicted rainfall.Full Answer >
Hurricanes are made when tropical storms form over sections of the ocean with warm, moist air and enough wind to begin a spiral. The primary cause is the latent heat from water evaporating off the surface of the ocean, which causes atmospheric imbalances that can increase wind speeds to hurricane levels. These can be higher than 150 miles an hour around the hurricane's eye.Full Answer >
Hurricanes occur mostly along the few degrees of latitude that surround the equator. They happen most often in the Pacific and Atlantic Oceans, but they are also common in a few other areas as well. The Indian Ocean also has regular hurricanes.Full Answer >
According to NASA, approximately 85 hurricanes occur worldwide each year. Not all of these hurricanes are devastating; some of them appear to be ordinary storms for the most part and only develop into official hurricanes for a few short hours, whereas others can be considered full-force hurricanes for several weeks. In order to be considered an official hurricane, in addition to having an eye with low atmospheric pressure, the circulating wind speeds should exceed 74 miles per hour.Full Answer >
