NASA research indicates that whenever a hot tower is spotted, a tropical cyclone will likely intensify. Less than 14 hours after the TRMM satellite captured an image of Ileana's rainfall and cloud heights, Ileana strengthened into a hurricane on Aug. 29.
NASA's TRMM satellite captured a view of Ileana's rainfall rates on Aug. 29 at 2:17 a.m. EDT. The purple areas indicated the heaviest rainfall rates, near 70 mm (2.7 inches) per hour. Some hot towering clouds around the center of circulation (also in purple) were higher than 9.3 miles (15 km). Credit: NASA/SSAI, Hal Pierce
NASA's Tropical Rainfall Measuring Mission (TRMM) satellite captured a view of Ileana's rainfall rates on Aug. 29 at 2:17 a.m. EDT and saw the heaviest rainfall rates, near 50 mm (2.0 inches) per hour in a band of thunderstorms southeast of the center of circulation. TRMM identified some hot towering clouds around the center of circulation that were higher than 9.3 miles (15 km).
On Aug. 30, satellite data showed a ragged double eyewall in the center of circulation. On Aug. 30 at 11 a.m. EDT, Hurricane Ileana's maximum sustained winds had increased to near 80 mph (130 kmh). Hurricane force winds extend outward up to 25 miles (35 km) from the center, which makes Ileana's hurricane-force wind area about 15 miles larger than Hurricane Kirk's in the Atlantic Ocean today. Ileana's tropical storm force winds extend outward up to 90 miles (150 km).The National Hurricane Center expects that Ileana won't strengthen much more before weakening on Aug. 31.
Ileana's center was about 305 miles (495 km) southwest of the southern tip of Baja California, Mexico, near latitude 20.2 north and longitude 113.7 west. Ileana is moving toward the northwest near 8 mph (13 kmh) and into cooler waters that will sap her strength.
The National Hurricane Center expects Ileana to weaken to a remnant low pressure area over the weekend of Sept. 1-2, while drifting west, and away from land.Text credit: Rob Gutro

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
