NASA's TRMM Satellite Provides a Rainfall Map of Mirinae's Flooding Rains

05.11.2009
Typhoon Mirinae drenched the Philippines and Vietnam over the last two weeks.

Typhoon Mirinae dropped heavy rain over the central Philippines after hitting as a category two typhoon with wind speeds of 85 knots (~98 mph). Mirinae weakened to a tropical storm as it moved into the South China Sea but briefly increased to typhoon strength just before hitting Vietnam on Monday, November 2 in the southern coastal province of Phu Yen.

The Tropical Rainfall Measuring Mission (TRMM) satellite is managed by NASA and the Japanese Space Agency, JAXA. From its vantage point in space, TRMM flew over Typhoon Mirinae during its lifetime and catalogued its rainfall.

TRMM-based, near-real time Multi-satellite Precipitation Analysis (TMPA) at the NASA Goddard Space Flight Center, Greenbelt, Md. was used to monitor rainfall with Mirinae. Rainfall totals were calculated for the period from October 26 to November 2, 2009. Tropical storm, typhoon and tropical depression symbols were overlaid to show the locations of Mirinae from when it came ashore in the eastern Philippines until being downgraded to a tropical depression over Vietnam.

The TRMM rainfall analysis indicated that Mirinae dropped heavy rainfall with totals over 200 mm (~7.8 inches) in an area southeast of Manila in the Philippines. Typhoon Mirinae dropped heavy rainfall over a much larger area of Vietnam with a small area having rainfall totals over 275 mm (~10.8 inches). As with typhoon Ketsana in late September, Mirinae pulled moist air from the South China Sea and forced it up over terrain causing the heaviest rainfall to occur north of the typhoon.

Typhoon Ketsana took a similar path to Mirinae when it caused disasters in the Philippines and Vietnam in late September 2009. Tropical storm Ketsana took a more northern track, also making a final landfall in Vietnam.

Heavy rain amounts (from satellites) and flood potential calculations (from a hydrological model) are updated every three hours globally with the results shown on the "Global Flood and Landslide Monitoring" TRMM web site pages (http://trmm.gsfc.nasa.gov).

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
