Infrared data from NASA's Terra satellite found the area of strongest storms in weakening Tropical Cyclone Sanba when it was over the island of Palawan.
Infrared light provides valuable temperature data to forecasters and cloud top temperatures give clues about highest, coldest, strongest storms within a hurricane.
On Feb.14 at 10:45 a.m. EDT (1435 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite analyzed Tropical Cyclone Sanba's cloud top temperatures in infrared light.
MODIS found a small area where cloud top temperatures of strongest thunderstorms, located in the Sargasso Sea, just southeast of Palawan. Those temperatures were as cold as or colder than minus 80 degrees Fahrenheit (minus 62.2 Celsius).
Cloud top temperatures that cold indicate strong storms that have the capability to create heavy rain.
The Joint Typhoon Warning Center noted at 10 a.m. EDT (1500 UTC) Sanba's maximum sustained winds had dropped to 28.7 mph (25 knots/46.3 kph). Sanba was moving into the South China Sea in a westerly direction at 5.7 mph (5 knots/9.6 kph).
Sanba was located about 480 nautical miles south-southwest of Manila, Philippines near 6.8 degrees north latitude and 119.2 degrees east longitude, about 480 nautical miles south-southwest of Manila, Philippines.
Sanba is crossing the southwestern part of the Sulu Sea, and will pass south of Palawan into the South China Sea. The system will not re-strengthen.

In two experiments performed at the free-electron laser FLASH in Hamburg a cooperation led by physicists from the Heidelberg Max Planck Institute for Nuclear physics (MPIK) demonstrated strongly-driven nonlinear interaction of ultrashort extreme-ultraviolet (XUV) laser pulses with atoms and ions. The powerful excitation of an electron pair in helium was found to compete with the ultrafast decay, which temporarily may even lead to population inversion. Resonant transitions in doubly charged neon ions were shifted in energy, and observed by XUV-XUV pump-probe transient absorption spectroscopy.
An international team led by physicists from the MPIK reports on new results for efficient two-electron excitations in helium driven by strong and ultrashort...
An international research group has observed new quantum properties on an artificial giant atom and has now published its results in the high-ranking journal Nature Physics. The quantum system under investigation apparently has a memory - a new finding that could be used to build a quantum computer.
