November 30th marks the official end of the 2024 Atlantic hurricane season. Throughout this active season, NOAA scientists set new records in tropical cyclone research that will improve forecasting accuracy, enhance our understanding of storm behavior, and strengthen preparedness efforts for communities in hurricane-prone regions. Their dedication and innovation contribute to a safer and more […]
In recent years, meteorologists have made strides in predicting the trajectory of tropical cyclones as models and forecasts have become more accurate. However, forecasting intensity remains a much larger challenge; small changes in atmospheric conditions can have a large impact on forecasts. To better understand why some forecasts are more accurate, scientists at NOAA’s Atlantic […]
As Hurricane Helene developed in the Gulf of Mexico, NOAA researchers gathered critical data from the sea and sky to better understand tropical cyclones and support the National Hurricane Center forecasters. This real time data gives meteorologists a clearer picture of the storm environment and structure, reducing forecast uncertainty. Researchers from NOAA’s Atlantic Oceanographic & […]
One of the largest challenges in hurricane research is studying the inner dynamics of a storm. The regions within the hurricane that provide the most valuable data are often the most inaccessible and dangerous to reach, creating an opportunity for researchers to utilize emerging technology to enter the storm. Small uncrewed aircraft systems (sUAS), commonly […]
A 12-year collaboration between NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) and the Indian Ministry of Earth Sciences (MoES) has culminated in a renewal of an Implementing Arrangement (IA) on Technical Cooperation in Development of Tropical Cyclone Numerical Weather Prediction System for the Indian Seas, which paves the way for advances in severe weather modeling. […]
In early July, the Caribbean experienced 165 mph winds as Category 5 Hurricane Beryl swept through the region. Beryl was unprecedented, becoming the Atlantic’s earliest forming Category 5 tropical cyclone on record. The storm developed and rapidly intensified to maximum wind speed in less than four days – a behavior uncommon this early in the season. Despite the unprecedented intensification, hurricane scientists with NOAA’s Atlantic Oceanographic and Meteorological Laboratory were prepared.
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.
Con una activa temporada de huracanes en el horizonte, la necesidad de una previsión fiable de huracanes está en el primer plano de nuestras mentes. Se espera que el aumento de la temperatura de la superficie del mar, el debilitamiento de la cizalladura vertical del viento y el aumento del monzón de África Occidental contribuyan al desarrollo de ciclones tropicales en el Atlántico. Para predecir estas tormentas en desarrollo, los meteorólogos emplean modelos que se basan en observaciones actuales y cálculos matemáticos para predecir el comportamiento y la trayectoria de una tormenta. Estos modelos son complejos y utilizan datos procedentes de diversas fuentes, como datos históricos, numéricos, oceánicos y atmosféricos, para generar sus predicciones.
Las mejoras en el modelo operativo de investigación y previsión meteorológica de huracanes allanaron el camino para la predicción y modelización de ciclones tropicales al reducir los errores de previsión de intensidad en un 45-50%.
En un nuevo e innovador estudio, los científicos de la Administración Nacional Oceánica y Atmosférica (NOAA, por sus siglas en inglés) dieron a conocer un avance significativo en el seguimiento y pronóstico de huracanes. El estudio, titulado "The G-IV Inner Circumnavigation: A Story of Successful Organic Interactions Between Research and Operations at NOAA", analiza cómo los científicos de la NOAA están mejorando los pronósticos de huracanes mediante el uso efectivo de NOAA [...]
