TRMM flew over Cyclone Gino on Thursday, Feb. 14 at 0806 UTC (3:06 a.m. EST) and measured the rainfall rates occurring throughout the storm. The bulk of the rainfall stretched from south to southeast of the center. The heaviest rain was falling at a rate of 2 inches (50 mm) per hour southeast of the center, and scattered throughout bands of thunderstorms. The bands of thunderstorms were wrapping from the east quadrant into the southwest quadrant of the storm.

As Gino continues in a southerly direction the vertical wind shear that is already affecting the storm's rainfall is expected to increase, according to the forecasters at the Joint Typhoon Warning Center (JTWC).
At 1500 UTC (10 a.m. EST), Cyclone Gino's maximum sustained winds had dropped to 70 knots (80 mph/129.6 kph). Tropical-storm-force winds extend out 110 nautical miles (126.6 miles/203.7 km) from the center of circulation.
Gino was located near 23.9 south latitude and 80.9 east longitude, about 1,110 nautical miles (1,277 miles/2,056 km) south-southeast of Diego Garcia and far from any land areas. Gino was moving to the south-southeast at 12 knots (13.8 mph/22.2 kph).
JTWC expects Gino to track southeastward along the southwestern edge of a subtropical ridge (elongated area) of high pressure where it will encounter strong vertical wind shear between 40 to 60 knots (46 to 69 mph/74 to lll kph) and sea surface temperatures as cool as 24 Celsius (75.2F). Sea surface temperatures of at least 26.6 C (80F) are needed for a tropical cyclone to maintain intensity. Any temperatures cooler than that, will limit thunderstorm development and weaken the storm.
According to JTWC forecasters, Gino should begin transitioning into an extra-tropical storm where the core of the storm changes from a warm core to a cold core, much like a typical mid-latitude low pressure area. Because of the increasing vertical wind shear and cooler sea surface temperatures, Gino may weaken quickly.

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...
