NASA's TRMM Satellite Adds Up Tropical Cyclone Ita's Australian Soaking

16.04.2014

After coming ashore on April 11, Tropical Cyclone Ita dropped heavy rainfall over the weekend that caused flooding in many areas of northeastern Australia's state of Queensland. The Tropical Rainfall Measuring Mission satellite known as TRMM gathered data on rainfall that was used to create a rainfall map at NASA.

TRMM is a satellite managed by both NASA and JAXA, the Japan Aerospace Exploration Agency. At NASA's Goddard Space Flight Center in Greenbelt, Md. Hal Pierce created a TRMM-based near-real time Multi-satellite Precipitation Analysis (TMPA).


This TRMM satellite rainfall map covers Tropical Cyclone Ita's life from April 1-14. Highest isolated rainfall was estimated around 400 mm/15.7 inches west of both Ingham and Townsville, Queensland. Ita's locations at 0600 UTC are shown overlaid in white.

The TMPA precipitation data covered the period from April 1 to 14, 2014 which starts when Ita formed in the Coral Sea and moved along northeastern Australia's coast. This TRMM satellite rainfall map estimated that some of the largest isolated rainfall totals were near 400 mm/15.7 inches west of both Ingham and Townsville, Queensland. 

A 3-D image of Ita was made at NASA using data collected by the TRMM satellite on April 14, 2014 at 0416 UTC/12:16 a.m. EDT after the tropical storm moved back into the Coral Sea.

TRMM's Precipitation Radar (PR) instrument found that the weakening tropical cyclone was still dropping rainfall at a maximum rate of over 161 mm/6.3 inches per hour over the Coral Sea. The 3-D image, created using TRMM PR data, showed that some storms within Ita were still reaching heights of over 13 km/8 miles as it was becoming extra-tropical.

Another NASA-shared satellite captured a visible look at Ita's remnants on April 15. The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite captured a look at the dying extra-tropical storm. VIIRS collects visible and infrared imagery and global observations of land, atmosphere, cryosphere and oceans.

When Suomi flew over Extra-Tropical Storm Ita on April 15 at 3:53 UTC/April 14 at 11:53 p.m. EDT, VIIRS visible data revealed that Ita's structure had elongated more than the previous day. The VIIRS image showed that strong northwesterly wind shear continued to hammer the storm because the bulk of the storm's clouds were pushed southeast of the center. Ita's remnants have taken on more of a frontal appearance today as they continue to weaken at sea.

Im Focus: Hubble survey unlocks clues to star birth in neighboring galaxy

In a survey of NASA's Hubble Space Telescope images of 2,753 young, blue star clusters in the neighboring Andromeda galaxy (M31), astronomers have found that M31 and our own galaxy have a similar percentage of newborn stars based on mass.

By nailing down what percentage of stars have a particular mass within a cluster, or the Initial Mass Function (IMF), scientists can better interpret the light...

Im Focus: How wind sculpted Earth's largest dust deposit

China's Loess Plateau was formed by wind alternately depositing dust or removing dust over the last 2.6 million years, according to a new report from University of Arizona geoscientists. The study is the first to explain how the steep-fronted plateau formed.

Im Focus: An engineered surface unsticks sticky water droplets

The leaves of the lotus flower, and other natural surfaces that repel water and dirt, have been the model for many types of engineered liquid-repelling surfaces. As slippery as these surfaces are, however, tiny water droplets still stick to them. Now, Penn State researchers have developed nano/micro-textured, highly slippery surfaces able to outperform these naturally inspired coatings, particularly when the water is a vapor or tiny droplets.

Enhancing the mobility of liquid droplets on rough surfaces could improve condensation heat transfer for power-plant heat exchangers, create more efficient...

Im Focus: Increasingly severe disturbances weaken world's temperate forests

Longer, more severe, and hotter droughts and a myriad of other threats, including diseases and more extensive and severe wildfires, are threatening to transform some of the world's temperate forests, a new study published in Science has found. Without informed management, some forests could convert to shrublands or grasslands within the coming decades.

"While we have been trying to manage for resilience of 20th century conditions, we realize now that we must prepare for transformations and attempt to ease...
