Eastern Pacific Season Off with a Bang: Amanda is First Major Hurricane

28.05.2014

The first tropical cyclone of the Eastern Pacific hurricane season grew into a major hurricane as Hurricane Amanda reached Category 4 status on the Saffir-Simpson scale over the Memorial Day holiday weekend. NASA and NOAA satellites watched as Amanda developed an eye while strengthening.

Fortunately, Amanda is far enough away from coastal Mexico that no watches or warnings are in effect today, May 27. 


On May 25 at 2100 UTC/5 p.m. EDT the MODIS instrument aboard NASA's Aqua satellite captured this visible image that revealed an eye in Hurricane Amanda.

On Sunday, May 25, Amanda strengthened into the first Major Hurricane in the Eastern Pacific Ocean. Maximum sustained winds were near 155 mph (250 kph). Amanda was centered near 11.8 north and 111.1 west, about 770 miles (1,240 km) south of the southern tip of Baja California.

Amanda is a Category 4 on the Saffir-Simpson scale. Minimum central pressure was near 932 millibars, and Amanda was crawling to the north at 2 mph (4 kph). Visible imagery from MODIS (Moderate Resolution Imaging Spectroradiometer) instrument aboard NASA's Aqua satellite and NOAA's GOES-West satellite captured imagery that revealed an eye in Hurricane Amanda.

On Monday, May 26, Hurricane Amanda started to weaken from its peak at a Category 4 status on the Saffir-Simpson scale. An image from NOAA's GOES-West satellite at 1200 UTC/5:00 a.m. PDT showed that Amanda's eye had become cloud-filled.

Amanda's maximum sustained winds were near 140 mph (220 kph) and the hurricane was moving to the north-northwest at 7 mph/ (11 kph). Amanda was centered near 13.1 north and 111.6 west, about 685 miles (1,105 km) south of the southern tip of Baja California.

On Tuesday, May 26 at 1500 UTC (11 a.m. EDT/8 a.m. PDT), Amanda's maximum sustained winds were near 120 mph (195 kph). Amanda is a category three hurricane on the Saffir-Simpson Hurricane wind scale. 

Amanda was centered near 14.7 north latitude and 112.3 west longitude, about 585 miles (945 km) south-southwest of the southern tip of Baja California, Mexico. Amanda was moving to the north-northwest at 6 mph (9 kph) and had a minimum central pressure of 957 millibars.

The U.S. Naval Research Laboratory in Washington, D.C. created a composite image using rainfall rate data from NASA-JAXA's Tropical Rainfall Measuring Mission (TRMM) satellite and infrared imagery from NOAA's GOES-West satellite to create a comprehensive look at Amanda. The infrared data showed the cloud extent, and the TRMM data showed heavy rainfall around Amanda's center falling at 1.4 inches (35 mm) per hour.

The National Hurricane Center forecasts weakening during the next 48 hours. In fact, NHC forecasters expect Amanda to weaken to a tropical storm by Thursday.

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...
