NASA saw Tropical Storm Haruna come together

20.02.2013
Tropical Storm Haruna came together on Feb. 19 in the Southern Indian Ocean and two NASA satellites provided visible and infrared imagery that helped forecasters see the system's organization.

A low pressure area called System 94S developed on Friday, Feb. 15 in the northern Mozambique Channel. Over the course of four days System 94S became more organized and by Feb. 19 it became Tropical Storm Haruna.


The sixteenth tropical cyclone of the Southern Indian Ocean season formed in the Mozambique Channel, and the MODIS instrument aboard NASA's Terra satellite captured this visible image of Tropical Storm Haruna on Feb. 19 at 0745 UTC.

On Tuesday, Feb. 19, Tropical Storm Haruna had maximum sustained winds near 35 knots (40.2 mph/64.8 kph). Haruna was located in the Mozambique Channel, near 21.4 south latitude and 40.9 east longitude, about 375 nautical miles (431.5 miles/694.5 km) west-southwest of Antananarivo, Madagascar. Microwave satellite imagery from the AMSU-B instrument confirmed the location of Haruna's low-level center. Haruna is moving south at 5 knots (5.7 mph/9.2 kph).

Infrared imagery from NASA's Atmospheric Infrared Sounder (AIRS) instrument taken on Feb. 18 and Feb. 19 showed the development of Haruna from a depression into a tropical storm. AIRS imagery on Feb. 19 indicated that the low-level circulation center was well-defined and symmetrical. The area of strongest thunderstorms appeared around the center of circulation and in a band of thunderstorms around the south and east of the center where cloud top temperatures were colder than -63F (-52C). The AIRS data on Feb. 19 also showed that the band of thunderstorms east of the center became fragmented over eastern Madagascar.

An instrument aboard NASA's Terra satellite called the Moderate Resolution Imaging Spectroradiometer, also known as "MODIS" captured a visible image of Tropical Storm Haruna on Feb. 19 at 0745 UTC (2:45 a.m. EST). The image showed the center of Haruna over the southern Mozambique Channel, between Mozambique on the African mainland to the west, and the island nation of Madagascar east. Haruna's eastern bands of thunderstorms were draped over Madagascar bringing showers, thunderstorms and gusty winds to the island.

The MODIS image was created by the MODIS Rapid Response Team at NASA's Goddard Space Flight Center in Greenbelt, Md.

According to forecasters at the Joint Typhoon Warning Center (JTWC), the organization that forecasts tropical cyclones in the Indian Ocean, Haruna is being guided by a low-to-mid-level subtropical ridge (elongated area) of high pressure and is expected to continue moving south until a low pressure area turns the tropical storm southeast.

Forecasters at the JTWC expect that Haruna will intensify over the next day or two and make a brief landfall over southern Madagascar. Haruna is expected to re-emerge into open ocean and vertical wind shear is forecast to increase with the low pressure area, weakening the storm.

Im Focus: It’s All in the Mix: Jülich Researchers are Developing Fast-Charging Solid-State Batteries

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.

The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
