Scientists use many tools to track hurricanes. First, they watch carefully for storms forming off the coast of Africa. Scientists use instruments mounted on satellites to look at the weather around a storm.
How do scientist accurately predict a hurricane?
Scientists predict hurricanes by gathering statistics to predict them on a seasonal basis, and by tracking it three to five days in advance once its path begins. It is possible to predict hurricanes up to a week in advance but, because of technical limitations, these predictions are sometimes incorrect.
Do scientists know how to stop Hurricanes?
Theoretically, science can reduce the strength of tornadoes and hurricanes. The basic concept is sound resonance. The basic concept of the mechanism can be explained as follows: It is assumed that a cluster of warm air over the ocean or land is an object just like a glass. As an object, it has natural frequency of vibration.

Why is NASA important to the study of hurricanes?
As NASA launches more sophisticated Earth-observing instruments, teams produce models with higher and higher resolutions, the ability to ingest such data, or the data assimilation procedure, increases. Each new instrument provides scientists and modelers a closer and more varied look at tropical cyclones. The higher the resolution of models and the capability of data assimilation systems, the easier it is to exploit data from satellite-borne instruments and to determine a hurricane’s intensity and size in terms of things such as the wind field and cloud extent.

The most recent NASA field mission to study hurricanes was the Hurricane and Severe Storm Sentinel or HS3. For three consecutive years, the HS3 mission investigated the processes that underlie hurricane formation and intensity change in the Atlantic Ocean basin. The mission used the Global Hawk, a high-altitude long-endurance aircraft capable of flights of 26 hours at altitudes above 55,000 ft. Flying from the Wallops Flight Facility in Virginia, the uninhabited Global Hawks could cover the entire Atlantic Ocean, enabling measurements of storms at early stages in the central or eastern Atlantic or spending 12-18 hours over storms in the western Atlantic.

How do hurricanes survive?
Hurricanes thrive in very specific conditions and need humid air and warm water to sustain their circulation. Williams says, “They need to be over warm water at least 79 degrees or more, and to a decent depth so when they spin up it can allow warmer water to replace it and still give fuel to the hurricane. Hurricanes also need humid air around them. Too much dry air getting into the system will cause it to weaken.”
How warm does water need to be for a hurricane?
Williams says, “They need to be over warm water at least 79 degrees or more, and to a decent depth so when they spin up it can allow warmer water to replace it and still give fuel to the hurricane. Hurricanes also need humid air around them. Too much dry air getting into the system will cause it to weaken.”.

But one of the most useful satellites for monitoring hurricanes wasn't meant for storm-watching at all. The TRMM satellite, or Tropical Rainfall Measuring Mission, launched in 1997. Intended to measure rainfall in the tropics, the satellite quickly proved invaluable for providing "CT scans" inside hurricanes.
What are the two sets of satellites that NOAA uses to track storms?
NOAA tracks developing storms and makes long-term forecasts with two sets of satellites: geostationary operational environmental satellites (GOES) and polar-orbiting operational environmental satellites (POES). The GOES satellites hover above the same spot for their life spans, and the POES satellites circle the planet in above the poles 14 times a day. [ Time-Lapse Video: 10 Years of GOES Weather Monitoring]

The weather models improved with new understanding of global ocean and atmospheric patterns that influence budding storms. But when researchers offer a tweak, such as computer algorithms that analyze satellite images for hot towers in hurricanes, NOAA wants reliability. So new algorithms are tested in real time at a computer complex in Boulder, Colo. The tests run side-by-side with current forecast models, taking on incoming feeds from weather satellites, ocean sensors and the hurricane hunters, said Frank Marks, director of NOAA's Hurricane Research Division. The computer-model newbies also have to prove their mettle against 1,000 past storms.

How does NOAA track hurricanes?
NOAA also utilizes a series of eight microsatellites known as the Cyclone Global Navigation Satellite System, or CYGNSS, to track different aspects of a hurricane. These eight satellites work together to image and gather data about hurricanes from their formation to their ultimate landfall. Everything from the outer wall of the hurricane and its spinoff winds to the very center of the storm is seen by these satellites; with more information coming in, scientists are able to better understand the formation and pattern of hurricanes to more accurately understand what could happen when they come into contact with land and humans.
What is the eye of a hurricane?
The eye of the hurricane is of particular interests to scientists who study hurricanes. The winds and behavior of this part of the storm are wildly unpredictable, which makes advances like the GOES-16 satellite that much more important. New algorithms put into place by the NOAA have been tested this year as well, improving the science of analyzing hurricanes. A new algorithm, nicknamed FV3 (Finite-Volume Cubed-Sphere Dynamical Core), allows scientists to create individual 3D cubes of data about a hurricane. This allows for a model that not only tracks speed and wind direction, but also updrafts and precipitation information to get a more accurate, big-picture look at the intensity of a hurricane. FV3 is the United States’ best attempt so far at more accurate hurricane modelling, and with more data comes the ability to create better systems for tracking these massive storms.

What is the NOAA hurricane hunter?
Air Force Reserve hurricane hunter fleet fly around and directly into the storm’s center, measuring weather data to determine the storm’s location, structure and intensity.
What is the NOAA flood map?
To better prepare communities for storm surge, NOAA’s National Hurricane Center has developed a potential storm surge flooding map, which is released when there is a hurricane watch or warning along the U.S. East or Gulf Coast. The map shows where storm surge flooding could occur in a near worst case scenario and gives the height in three feet intervals that water could reach above normal dry ground.
What does NHC do on social media?
NHC also posts the same information on social media to ensure a wide distribution. When watches or warnings are posted for the U.S. coastline, NHC opens a television media pool to give live interviews to national news outlets and the local TV stations in the path of the storm. Page 2 of 5. Hurricane impacts.
