NASA sees rainfall in Tropical Storm Francisco

25.10.2013
NASA's TRMM satellite flew above the center of Tropical Storm Francisco in the western North Pacific Ocean early on Oct. 24 and data was used to create a 3-D image of the storm's structure.

Tropical Storm Francisco came into the view of the Tropical Rainfall Measuring Mission or TRMM satellite at 0919 UTC/5:19 a.m. EDT. Francisco is somewhat close to Super-typhoon Lekima, also in the northwestern Pacific Ocean. Lekima was located southeast of Tropical Storm Francisco over the open waters of the Pacific.

At NASA's Goddard Space Flight Center in Greenbelt, Md. the data TRMM gathered was used to create imagery of the storm. Precipitation data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments were overlaid on infrared images from TRMM's Visible and InfraRed Scanner (VIRS).

TRMM data showed a difference between Lekima and Francisco. TRMM's PR data revealed that Lekima had a small well defined eye at the center of the super typhoon with another concentric outer replacement eye wall. Rain was falling at a rate of over 130mm/~5.2 inches per hour in the powerful storms in Lekima's outer eye wall. Francisco was also a super typhoon on Oct. 20, 2013 but had greatly weakened by the time of the latest TRMM pass. Francisco now had a very large area in the center of the storm that was rain free. Lekima was the fourth super typhoon in the western Pacific this year with wind speeds estimated to be over 130 knots/~150 mph.

Radar reflectivity data from TRMM's PR instrument were used to create 3-D images that showed differences between super typhoon Lekima and tropical storm Francisco. TRMM is managed by both NASA and the Japan Aerospace Exploration Agency.

On Oct. 24 at 1500 UTC/11 a.m. EDT, Francisco's maximum sustained winds were near 60 knots/69 mph/111 kph. Francisco was centered near 26.9 north and 130.8 east, about 134 nautical miles east of Kadena Air Base, Okinawa, Japan. Francisco was moving to the northeast at 7 knots/8 mph/12.9 kph and away from the island.

Francisco is being pushed to the northeast by mid-latitude westerly winds, which are also affect Super-typhoon Lekima behind it. The tropical storm appears elongated on satellite imagery today showing the effect that the westerlies are having on it. Francisco is expected to continue on a northeast track paralleling eastern Japan, but staying out to sea.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
