NASA research indicates that whenever a hot tower is spotted, a tropical cyclone will likely intensify. Less than 14 hours after the TRMM satellite captured an image of Ileana's rainfall and cloud heights, Ileana strengthened into a hurricane on Aug. 29.
NASA's TRMM satellite captured a view of Ileana's rainfall rates on Aug. 29 at 2:17 a.m. EDT. The purple areas indicated the heaviest rainfall rates, near 70 mm (2.7 inches) per hour.

NASA's Tropical Rainfall Measuring Mission (TRMM) satellite captured a view of Ileana's rainfall rates on Aug. 29 at 2:17 a.m. EDT and saw the heaviest rainfall rates, near 50 mm (2.0 inches) per hour in a band of thunderstorms southeast of the center of circulation. TRMM identified some hot towering clouds around the center of circulation that were higher than 9.3 miles (15 km).
On Aug. 30, satellite data showed a ragged double eyewall in the center of circulation. On Aug. 30 at 11 a.m. EDT, Hurricane Ileana's maximum sustained winds had increased to near 80 mph (130 kmh). Hurricane force winds extend outward up to 25 miles (35 km) from the center, which makes Ileana's hurricane-force wind area about 15 miles larger than Hurricane Kirk's in the Atlantic Ocean today. Ileana's tropical storm force winds extend outward up to 90 miles (150 km).The National Hurricane Center expects that Ileana won't strengthen much more before weakening on Aug. 31.
Ileana's center was about 305 miles (495 km) southwest of the southern tip of Baja California, Mexico, near latitude 20.2 north and longitude 113.7 west. Ileana is moving toward the northwest near 8 mph (13 kmh) and into cooler waters that will sap her strength.
The National Hurricane Center expects Ileana to weaken to a remnant low pressure area over the weekend of Sept. 1-2, while drifting west, and away from land.Text credit: Rob Gutro

Diving robots find Antarctic winter seas exhale surprising amounts of carbon dioxide

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...
