NASA satellites see Hurricane Celia strengthen and open an eye

24.06.2010
Hurricane Celia dropped to a Category One hurricane during the late afternoon hours on June 22, and today, June 23 by 11 a.m. EDT, it had powered back up to a Category Two hurricane in the Eastern Pacific Ocean. Satellite imagery confirmed the strengthening visibly with the emergence of an eye in the hurricane.

Celia's maximum sustained winds were up to 100 mph at 11 a.m. EDT on June 23. That's a jump from the 80 mph maximum sustained winds it had just six hours earlier. Celia's hurricane force winds extend outward up to 30 miles (45 km) from the center and tropical storm force winds extend outward up to 105 miles (165 km).

Imagery taken this morning at 8 a.m. EDT from the Geostationary Operational Environmental Satellite known as GOES-11 revealed that Celia has an eye. The image also showed the newly formed Tropical Storm Darby to the east of Celia. The satellite image was created by NASA's GOES Project, located at NASA's Goddard Space Flight Center, Greenbelt, Md. GOES-11 is operated by the National Oceanic and Atmospheric Administration.

Two days ago on Monday, June 21, NASA's Aqua satellite flew over Celia and the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument captured a true-color image of Celia that did not show an eye.

Currently, Celia is far from Mexico, some 740 miles south of the southern tip of Baja California, near 12.2 North latitude and 109.2 West longitude. Celia is moving west near 12 mph (19 km/hr) and has a minimum central pressure near 974 millibars. Celia is expected to turn toward the west-northwest in the next day or two and possibly strengthen.

Vertical wind shear is decreasing which has enabled Celia to strengthen. The National Hurricane Center in Miami, Fla. forecasts wind shear near Celia to continue weakening as low or lower than 6 mph (5 knots), which will enable Celia to strengthen a little more over the next 24 to 36 hours. However, Celia will also track into cooler waters, which will limit it's ability to power up, and as it continues west-northwest, it will begin weakening.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

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...

Im Focus: Climate satellite: Tracking methane with robust laser technology

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...

Im Focus: How protons move through a fuel cell

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...

Im Focus: A unique data centre for cosmological simulations

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...
