NASA sees former tropical storm bow out 'Grace-fully'

10.09.2015

NASA-NOAA's Suomi NPP satellite passed over former Tropical Storm Grace and saw the storm had weakened into an open wave of low pressure. Wind data from NASA's RapidScat was also used to confirm Grace's degeneration.

NASA-NOAA's Suomi satellite flew over Grace at 4:45 UTC (12:45 a.m. EDT) on Sept. 9 and the VIIRS instrument aboard captured an infrared image of the storm. Satellite data showed Grace no longer had a closed circulation and is now an open wave.

At 11 a.m. EDT (1500 UTC), on September 9, the remnants of Grace were located near latitude 14.5 North and longitude 49.0 West. That puts Grace's remnants about 825 miles (1,325 km) east of the Lesser Antilles.

The remnants were moving toward the west near 18 mph (30 kph) and this general motion is expected to continue over the next couple of days. Maximum sustained winds were near 30 mph (45 kph) with higher gusts. The National Hurricane Center said that "little change in strength is expected over the next day or two." The estimated minimum central pressure is 1008 millibars.

NHC Forecaster Pasch noted that "Data from the Rapidscat instrument onboard the International Space Station showed that there were no longer any westerly surface winds in Grace. This was confirmed by animation of high-resolution visible imagery that showed no westerly low-cloud motions." Since Grace had opened up into a wave, the National Hurricane Center issued its final advisory.

Grace's remnant wave is expected to continue moving quickly to the west. NHC noted that the remnants could produce some gusty winds and showers over portions of the Lesser Antilles within a couple of days.

Im Focus: Superconducting vortices quantize ordinary metal

Russian researchers together with their French colleagues discovered that a genuine feature of superconductors -- quantum Abrikosov vortices of supercurrent -- can also exist in an ordinary nonsuperconducting metal put into contact with a superconductor. The observation of these vortices provides direct evidence of induced quantum coherence. The pioneering experimental observation was supported by a first-ever numerical model that describes the induced vortices in finer detail.

These fundamental results, published in the journal Nature Communications, enable a better understanding and description of the processes occurring at the...

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
