NASA sees Cyclone Giovanna enter the Mozambique Channel

16.02.2012
Cyclone Giovanna crossed over the island of Madagascar leaving flooding and damages in its wake and has now entered the Mozambique Channel. NASA's Aqua satellite captured an image that showed a ragged eye still exists, and the storm is regaining strength in the warm Channel waters.

Once Giovanna traversed the island nation of Madagascar and entered the Mozambique Channel, the body of water between Madagascar and Mozambique on the African mainland, NASA's Aqua satellite passed overhead and captured a visible image with the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument.

MODIS captured the image at 10:45 UTC (5:45 a.m. EST) on February 15. The image showed that convection (rising air that forms the thunderstorms that make up the storm) had diminished greatly in the northwestern quadrant of the storm,. The MODIS image also showed that thunderstorms were now building around the rest of the tropical storm as a result ove moving into the warm waters of the Mozambique Channel. Sea surface temperatures of at least 80 Fahrenheit (26.6 Celsius) are needed to maintain a tropical cyclone, and temperatures in the Channel are as warm as ~88 Fahrenheit (31 Celsius).

On February 15, 2012 at 0300 UTC (Feb. 14 at 10 p.m. EST), Tropical Storm Giovanna's maximum sustained winds were near 40 knots (46 mph/74 kph). Tropical Cyclone Giovanna's center was located approximately 250 nautical miles west-southwest of Antananarivo, Madagascar, near 20.8 South and 42.4 East. It is moving to the west-southwest at 13 knots (15 mph/24 kph).

BBC News reports that at least two people died from storm related incidents, and the town Vatomandry, south of where Giovanna made landfall in east-central Madagascar, has experienced a lot of damage. BBC News reports that at least 60 percent of homes in the town were damaged or destroyed. Trees, phone and power lines have been downed, especially in eastern areas, as recovery efforts continue.

The Joint Typhoon Warning Center uses satellite data and forecast computer models to create forecasts. The current forecast for Giovanna now takes it on a westerly track toward Mozambique by the week's end. The forecast also indicates that wind shear will increase, which will prevent the storm from strengthening further. Residents along the southeastern coast of Mozambique should monitor the path of this tropical storm.

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.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
