Tropical Cyclone Freddy breaks records as the longest-lasting cyclone on record. Spanning 36 days, it traveled from the Australia to Africa, nearly 33% of the Earth’s circumference.
With an active hurricane season on the horizon, the need for reliable hurricane forecasting is at the forefront of our minds. Heightened sea surface temperatures, weakened vertical wind shear, and an enhanced West African monsoon are expected to contribute to the development of tropical cyclones in the Atlantic. To predict these developing storms, meteorologists employ models that rely on current observations and mathematical calculations to predict a storm’s behavior and track. These models are complex and utilize inputs from a variety of sources including historic, numeric, oceanic, and atmospheric data to generate their predictions.
Improvements in the operational Hurricane Weather Research and Forecasting Model paved the way for tropical cyclone prediction and modeling by lowering intensity forecast errors by 45-50%.
November 30th marked the official end to the 2022 Atlantic hurricane season. Scientists and forecasters from across NOAA worked tirelessly throughout the season to conduct critical tropical cyclone research. This year, NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) coordinated the longest series of missions into a single tropical system, arranged multiple observing assets for simultaneous data collection, deployed new sUAS technology, and included a novel “moving nest” to our next-generation hurricane model.
This summer during the 2022 Atlantic hurricane season, scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) will once again be on the frontlines helping NOAA prepare the public for severe weather. They will also conduct new research on the complex processes of how tropical cyclones form, develop, and dissipate.
Scientists at AOML are preparing for the active anticipated 2021 Atlantic hurricane season with the introduction of new observation tools, modeling techniques, and field campaigns to improve hurricane intensity and track forecasts.
Scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory are now focusing on what happens where the sea meets the atmosphere to help solve the hurricane intensity problem. The place right above where the air meets the sea is called the planetary boundary layer. The ocean drives global weather. By building on past research, scientists have determined that factors in the boundary layer and underlying ocean such as salinity, temperature, currents, wave and wind patterns, precipitation, are crucial to understanding the energy that fuels a hurricane.
NOAA Hurricane Hunters continue reconnaissance for Tropical Storm Eta, which threatens to bring tropical cyclone hazards to south Florida as it restrengthens over water.
Tasked by the Environmental Modeling Center (EMC) and the National Hurricane Center (NHC), NOAA’s P-3 and G-IV aircraft have conducted reconnaissance for Tropical Storm Eta. Missions are scheduled to proceed through the weekend.
