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: Abrupt motion sharpens x-ray pulses

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.

A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...

Im Focus: Physicists Design Ultrafocused Pulses

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.

Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...

Im Focus: Flexible proximity sensor creates smart surfaces

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.

At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
