A new study refines hurricane intensity prediction models by incorporating the impact of large eddies on wind speed and air humidity. The research suggests that large eddies contribute significantly to energy, heat, and moisture transfer between the ocean and atmosphere.
The TRMM satellite has provided new insights into rainfall patterns in tropical cyclones, revealing that heaviest rains fall within 50km of a storm's center. This study improves forecast accuracy and can help with the development of better weather forecasts.
A study by NASA researchers found that tropical cyclones with 'hot towers' in their eyewall are twice as likely to intensify within six hours. The researchers used TRMM satellite data to compile global statistics on hot tower occurrence and define a nine-mile high threshold for classification.
Since 1992's Category 5 Hurricane Andrew, NASA satellites have provided critical data to improve hurricane forecasts. The Tropical Rainfall Measuring Mission (TRMM), QuikSCAT, and Aqua satellites offer insights into rainfall intensity, wind patterns, and ocean temperatures.
Researchers have developed a new method to detect potential tropical cyclones using satellite data, allowing for earlier warning times of up to 40 hours. This technique uses wind speed data from the SeaWinds scatterometer on NASA's QuikSCAT satellite to identify areas of rotating winds.
Researchers have used Empirical Mode Decomposition to analyze patterns in tropical storm occurrences along the East Coast. The technique reveals four distinct cycles, or modes, that determine the number of hurricanes making landfall each year.
The new satellite-based tools provide unprecedented insights into tropical cyclones, allowing scientists to break them down into their component parts. This 'data fusion' technique enables the development of advanced hurricane forecasting methods, such as Wavetrak, which sheds light on the origin and intensity of these storms.
