NASA's Aqua satellite provided an image of Imelda that showed wind shear that has been hammering the storm, had pushed the bulk of the storm's precipitation southeast of the center.
NASA's Aqua satellite passed over Tropical Cyclone Imelda on April 16 at 0943 UTC (5:43 a.m. EDT). Aqua captured this visible image that clearly showed the center of circulation, and most of the precipitation southeast of the center.
Wind shear at higher levels has increased to as high as 30 knots (34.5 mph/55.5 kph), according to upper level analysis of the atmosphere that was conducted by the Joint Typhoon Warning Center. That stronger wind shear is weakening Imelda quickly.
NASA's Aqua satellite passed over Tropical Cyclone Imelda on April 16 at 0943 UTC (5:43 a.m. EDT) and the Moderate Resolution Imaging Spectroradiometer instrument captured a visible image of the storm that clearly showed most of the precipitation had been pushed southeast of the center from wind shear. Animated multispectral satellite imagery showed that the low level circulation center was fully exposed and there was no deep convection or strong thunderstorms developing over the previous 12 hours.
The last official warning on Imelda was issued on April 16 at 0900 UTC (5 a.m. EDT), when Imelda's maximum sustained winds had fallen to 35 knots (40 mph/65 kph). The weakening tropical storm was located near 21.2 south and 62.9 east, about 410 nautical miles (471.8 miles/ 759.3 km) east of La Reunion island and moving to the southeast at 5 knots (5.7 mph/9.2 kph).
Imelda is expected to continue weakening and should dissipate in the next day or two.

World first experiments on sensor that may revolutionise everything from medical devices to unmanned vehicles
The new sensor - capable of detecting vibrations of living cells - may revolutionise everything from medical devices to unmanned vehicles.
Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
