NASA's Aqua satellite gathered infrared data on the Southern Indian Ocean's Tropical Cyclone Glenda that showed powerful thunderstorms circling the storm's center.
NASA's Aqua satellite passed over Glenda and the AIRS instrument aboard captured infrared data on the storm on Feb. 25 at 06:47 UTC (1:47 A.M. EST). At that time, Glenda's maximum sustained winds were near 55 knots (63.2 mph/102 kph).
The infrared data measured cloud top temperatures and found the thunderstorms surrounding the center, were high, and powerful, with cloud top temperatures near -63F/-52C.
NASA research has shown that storms with cloud tops that cold have the potential to drop heavy rain. The infrared image also showed a hint of an eye forming in the center of circulation.
On Feb. 26 at 0900 UTC (4 a.m. EST), Tropical Cyclone Glenda's maximum sustained winds remained near 55 knots (63.2 mph/102 kph), but it is expected to strengthen.
It was centered near 20.7 south latitude and 67.6 east longitude, about 586 nautical miles (674 miles/1,085 km) east of Port Louis, Mauritius, far from land. Glenda was moving to the south-southwest at 7 knots (8 mph/13 kph).
The Joint Typhoon Warning Center (JTWC) noted "Animated multispectral satellite imagery depicts thinning convection with tightly-curved banding wrapping into a partially-exposed low-level circulation center.
Although the sea surface temperatures and ocean heat content are marginal, favorable upper-level conditions are expected to persist, allowing moderate Intensification over the next 36 hours."
Glenda is expected to gradually intensify and then turn southeast and transition into an extra-tropical storm.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
