Tropical Storm Amanda Gets Bisected and Animated by NASA's CloudSat

30.05.2014

Tropical Storm Amanda continues to weaken in the eastern Pacific from dry air and wind shear. NASA's CloudSat satellite captured a view of the storm from the side revealing heavy precipitation when the storm was the most powerful May Eastern Pacific on record.

NASA's CloudSat satellite flew over Hurricane Amanda in the east Pacific on May 25, 2014 at 2100 UTC (5 p.m. EDT) and was about 40 km (24.8 miles) outside of the center of the storm.

Hurricane Amanda contained estimated maximum winds of 130 knots (150 mph/240 kph) and minimum pressure of 935 millibars at the time of this overpass. CloudSat passed over the eastern section of the storm, after it reached peak intensity earlier in the day. On May 25 Hurricane Amanda had become the strongest May hurricane on record for the Eastern Pacific basin.

CloudSat data showed a deep area of moderate to heavy-moderate precipitation below the freezing level (where precipitation changes from frozen to liquid). Cloudsat also showed a deep anvil cloud deck that extended northward with smaller cumulus clouds detectable beneath.

Four days later, Amanda quickly weakened as a result of dry air moving into the system and wind shear.

National Hurricane Center (NHC) forecaster Brennan noted at 5 a.m. EDT on May 29 in the NHC Discussion that "Amanda has come unglued during the past few hours, with the remaining deep convection now located more than 2 degrees to the northeast of the low-level center. This weakening appears to be due to the usually potent combination of vertical wind shear and mid/upper-level dry air advecting (moving) over the cyclone."

By 11 a.m. EDT (8 a.m. PDT) on May 29, the National Hurricane Center (NHC) reported that Amanda weakened to a depression. The center of Tropical Depression Amanda was located near latitude 16.3 north and longitude 110.0 west, about 455 miles (735 km) south of the southern tip of Baja California, Mexico. Because Amanda was so far from land, there were no warnings or watches in effect.

Amanda's maximum sustained winds have decreased to near 35 mph (55Kph) with higher gusts. The NHC discussion at 11 a.m. EDT noted that Amanda's center had become increasingly elongated and diffuse. The estimated minimum central pressure is 1006 millibars.

The depression was moving toward the east near 7 mph (11 kph) and NHC expects a slower eastward or east-northeastward motion during the next day or so. The NHC expects Amanda to become a remnant low in about a day.

Im Focus: Computational high-throughput screening finds hard magnets containing less rare earth elements

Permanent magnets are very important for technologies of the future like electromobility and renewable energy, and rare earth elements (REE) are necessary for their manufacture. The Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, has now succeeded in identifying promising approaches and materials for new permanent magnets through use of an in-house simulation process based on high-throughput screening (HTS). The team was able to improve magnetic properties this way and at the same time replaced REE with elements that are less expensive and readily available. The results were published in the online technical journal “Scientific Reports”.

The starting point for IWM researchers Wolfgang Körner, Georg Krugel, and Christian Elsässer was a neodymium-iron-nitrogen compound based on a type of...

Im Focus: Atomic precision: technologies for the next-but-one generation of microchips

In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.

In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...

The trend-forward world of display technology relies on innovative materials and novel approaches to steadily advance the visual experience, for example through higher pixel densities, better contrast, larger formats or user-friendler design. Fraunhofer ISC’s newly developed materials for optics and electronics now broaden the application potential of next generation displays. Learn about lower cost-effective wet-chemical printing procedures and the new materials at the Fraunhofer ISC booth # 1021 in North Hall D during the SID International Symposium on Information Display held from 22 to 27 May 2016 at San Francisco’s Moscone Center.
