Some of the tools hurricane centers use to track and forecast storms include satellites, reconnaissance aircraft, ships, buoys and radar systems. Satellites are used in remotely measuring the intensity and track of the hurricane as the tropical cyclone travels over the ocean.Continue Reading
Forecasters interpret satellite data to calculate the storm’s characteristics, such as the location of its center, its previous movement and its maximum wind speed or intensity. The forecasting procedure typically starts by gathering available observations. Satellites regularly monitor a hurricane from the formation of the storm until its dissipation.
In North America, the National Hurricane Center predicts the size, structure, intensity and track of tropical cyclones, storm surges, rainfall and tornadoes caused by tropical cyclones. Other forecast agencies conduct procedures similar to the process used by the NHC, but they tailor their procedures to their specific areas of responsibility.
The U.S. Air Force and National Oceanic and Atmospheric Administration hurricane aircraft, dropsondes and land stations directly keep track of any Atlantic hurricane that threatens to make landfall. The Chief, Aerial Reconnaissance Coordination, All Hurricanes, or CARCAH, is responsible for organizing tropical cyclone reconnaissance flights, which provide data to CARCAH, the NHC forecasters and the public. Land-based radars are used to obtain data on precipitation and wind velocity as the typhoon draws near the coast.Learn more about Storms
Hurricanes are extremely powerful storms that form above ocean water and can cause devastating damage in coastal areas as a result of powerful winds, heavy rains, high waves and water levels. In meteorological terms, hurricanes are low-pressure systems that form in tropical areas.Full Answer >
Hurricanes are unable to form along the equator because of the zero Coriolis Effect at 0 latitude, which is the force required for the spinning motion of these violent storms. One of the necessary environmental conditions for an atmospheric disturbance to become a full-blown hurricane is for the rough weather conditions to occur at least 300 miles away from the equator. The Coriolis Effect, which decreases the farther from the equator, is the apparent force that tends to move rotating objects to the right.Full Answer >
Since 1886, the first year that data is available, 41 storms classified as hurricanes have passed within 75 miles of the Houston/Galveston county warning area as of 2014. According to climatecentral.org, a hurricane strength storm is expected strike the Texas coast once every 9 to 16 years.Full Answer >
Tropical storms originating in the Atlantic Ocean are called hurricanes while the same storms originating in the Pacific are called typhoons. Both storms are associated with winds that move in a circular vortex pattern. In contrast, monsoons are heavy rains created by a seasonal increase in temperature. Monsoons move in a straight line pattern.Full Answer >
