Tropical Depression Dokuri weaker, but still potent

29.06.2012
Tropical Storm Dokuri weakened into a tropical depression today, but NASA infrared satellite imagery is still showing some areas of strong convection and thunderstorms in the storm and they're being pushed away from the center.

NASA's Aqua satellite passed over Tropical Storm Dokuri on June 27 on 0435 UTC (12:35 a.m. EDT). Infrared data from the Atmospheric Infrared Sounder (AIRS) instrument onboard indicated there were still some strong showers and thunderstorms within the system. Those cloud top temperatures were colder than -63 Fahrenheit (-52 Celsius), indicating strong uplift in the atmopshere, and thunderstorms within Dokuri that have the capability for heavy rainfall.

Infrared data shows a fully-exposed low level-circulation center. The strongest convection (rising air that creates thunderstorms that make up the system)are being pushed to the southwest due to strong northeasterly vertical wind shear.

Warnings are up in the Philippines as Doksuri (known there as Dindo) continues to move north of Luzon today. Public storm warning signal #1 is in effect in Abra, Kalinga, Isabela, Ilocos Sur, Mt. Province, Ifugao, La Union, Benguet, Pangasinan, Nueva Vizcaya and Quirino. Public storm warning signal #2 is also in effect for Cagayan, Calayan Group of Islands, Babuyan Group of Islands, Batanes Group of Islands, Apayao, Ilocos Norte.

On June 28, 2012 at 1500 UTC (11 a.m. EDT), Tropical Storm Doksuri had maximum sustained winds near 35 knots. It was located approximately 335 nautical miles north of Manila, Philippines, near 20.4 North and 120.7 East. It was moving to the west-northwestward at 17 knots. The strongest convection and thunderstorms were located over northern Luzon at this time, and are moving off the northwestern coast of the Philippines.

Doksuri has weakened as it passes to the north of Luzon. Doksuri is expected to continue tracking west and make landfall near Hong Kong in two days.

Im Focus: Electron cryo-microscopy: Using inexpensive technology to produce high-resolution images

Biochemists at Martin Luther University Halle-Wittenberg (MLU) have used a standard electron cryo-microscope to achieve surprisingly good images that are on par with those taken by far more sophisticated equipment. They have succeeded in determining the structure of ferritin almost at the atomic level. Their results were published in the journal "PLOS ONE".

Electron cryo-microscopy has become increasingly important in recent years, especially in shedding light on protein structures. The developers of the new...

Im Focus: Electrons in the fast lane

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.

Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....

Im Focus: The lightest electromagnetic shielding material in the world

Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivalled in terms of weight.

Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic...
