NASA-NOAA’s Finnish nuclear power plant analyzes record-breaking hurricane Lorenzo
Over the weekend of September 28 and 29, Hurricane Lorenzo reached a short Class 5 intensity and became the strongest hurricane ever on the east side of the Atlantic Ocean. Lorenzo has also achieved and participated in some other significant statistics. NASA-NOAA’s Finland nuclear power plant satellite provided infrared data over two days, providing forecasters with changes in the eye of the storm, strong thunderstorms and the resulting gravitational waves.
Recording setting
On Saturday, Sept. 28, when Lorenzo reached Class 5 (Class 5) power with Hurricane Wind Power of Saffir-Simpson, it was at a location more than 600 miles east-northeast of the previous record-breaking Cat 5 storm. It also had the lowest atmospheric pressure east of 50 degrees west longitude when the pressure dropped to 925 millibars.
Since 1960, there have been 26 class 5 storms. Hurricane Camille was the first and Lorenzo the last. In the last 3 years, six storms reached this level of intensity. Others are Dorian, Michael, Maria, Irma and Matthew). Earlier this year, Dorian reached Class 5 strength, so this year is only associated with six other years that included more than one Cat 5 storm since the start of the record. Other years that have had more than one Cat 5 storm include 1932, 1933, 1961, 2005, 2007, and 2017.

The Finnish nuclear power plant satellite crossed the Eastern Atlantic on September 29 after the Lorenzo peak and weakened back to a Class 4 hurricane. The Visible Infrared Imaging Radiometer Suite (VIIRS) of the Finnish nuclear power plant provided infrared data from Lorenzo.
Tropical cyclones are made up of hundreds of thunderstorms, and infrared data can indicate where the strongest storms are located. They can do it because infrared data provides temperature data, and the strongest thunderstorms that reach the highest atmosphere have the coldest peak cloud temperature.
“As with other powerful hurricanes, the eye was well defined along with the mesovorts,” said William Straka III, a researcher who created some images of Finland’s nuclear power plant at the University of Wisconsin – Madison, Space Science and Engineering Center (SSEC), Cooperative Institute for Meteorological Satellite Surveys (CIMSS) for. The intensity of the storm also produced gravitational waves in the mesosphere. Straka said: “Something interesting is to note that the gravitational waves of the Lorenzo mesosphere can be seen up to 1,180 km (733 miles) away. This is not unheard of, but still worth noting.”
Mesovortexes are small-scale rotational properties that occur in convective storms, such as the eye wall of tropical cyclones. They can be tens of kilometers or miles in diameter or less, and can be very powerful.
NOAA defines a gravity wave as a wave that results from the effect of gravity on density variations in a layered atmosphere. A general classification for a protective wave, a mountain wave, and many other waves formed in the atmosphere.
At 0300Z on Sept. 30 (23:00 EDT on Sept. 29), the National Hurricane Center or NHC Public Advisory Authority found that Hurricane Lorenzo’s winds were 110 mph, making it barely a Class 3 hurricane. Three hours later at 2.00 EDT (0600 UTC) on September 30, Lorenzo had weakened into a Class 2 hurricane when the wind had dropped to 105 mph. As NASA-NOAA’s Finland nuclear power plant satellite passed over Lorenzo, it re-analyzed the storm in infrared light. There were mesospheric gravity waves in the nuclear images, probably due to the energy released as the storm weakened. The nuclear power plant also showed an eye filled with a cloud and the clouds expanded to the northern quarter. Both observations support the NHC Forecast debate at 5.00 EDT (0900 UTC).
Hurricane Lorenzo on September 30th
On September 30, 2019, at 8:00 a.m. EDT (1200 UTC), NOAA’s National Hurricane Center released clocks for the Azores. The Azores are an autonomous region of Portugal. The Azores consist of nine inhabited islands. Everyone is under Lorenzo’s watch. The NHC released a hurricane watch for Flores, Corvo, Faial, Pico, Sao Jorge, Graciosa, Terceira and the Tropical Storm Watch is in force in Sao Miguel, Santa Maria.
At that time, the center of Hurricane Lorenzo was located near 29.4 degrees north latitude and 42.9 degrees west. Lorenzo is moving northeast from north to near 20 km / h. The maximum sustained wind is close to 105 km / h (165 km / h) and gusts more. Hurricane winds extend outward up to 150 kilometers from downtown and tropical storm winds extend outwardly up to 405 kilometers. The estimated minimum pressure is 957 millibars.
Lorenzon track
On the forecast track, downtown Lorenzo is expected to run near the western Azores on Wednesday, October 2nd. Deterioration is forecast for the next two days, but Lorenzon is forecast to remain a major and severe hurricane as it passes the Azores.
In addition to threatening the Azores, Lorenzo has quite an impact in the North Atlantic despite being in the North Atlantic. The NHC said: “Major swellings are spreading over much of the North Atlantic basin. These swellings are likely to cause life-threatening surfing and tear up current conditions.”
Hurricanes are the strongest weather event in the country. NASA’s expertise in space and scientific research contributes to essential services provided to Americans by other federal agencies, such as hurricane weather forecasts.
