NASA measuring Tropical Storm Yasi's inland rainfall from space

04.02.2011
Tropical Cyclone Yasi has continued moving through inland Queensland, Australia and has weakened to a tropical depression today. NASA and JAXA's TRMM satellite passed over Yasi as it continued to drop moderate to heavy rainfall.

On February 3 at 0300 UTC (Feb. 2 at 10 p.m. EST/1 p.m. Australia local time) Tropical cyclone Yasi continued over land as a tropical storm. Yasi's maximum sustained winds were near 60 knots (69 mph/111 kmh). It was moving west-southwest near 20 knots/23 mph/37 kmh). It was located about 200 miles (321 km) southwest of Cairns, Australia near 19.3 South and 143.4 East.


The TRMM satellite flew above the cyclone at 0339 UTC (Feb. 2 at 10:39 p.m. EST/1:39 p.m. Australia local time) collecting data on rainfall rates. Yasi was still dropping moderate to heavy rain over Australia in an area southeast of the Gulf of Carpentaria. The yellow and green areas indicate moderate rainfall between .78 to 1.57 inches per hour. Red areas are heavy rainfall at almost 2 inches per hour. Credit: NASA/SSAI, Hal Pierce

Just 39 minutes after the position of Yasi's center was determined, the Tropical Rainfall Measuring Mission (TRMM) satellite flew above the cyclone at 0339 UTC (Feb. 2 at 10:39 p.m. EST/1:39 p.m. Australia local time) collecting data on rainfall rates. Yasi had weakened to tropical storm strength but TRMM Microwave Imager (TMI) and Precipitation Radar (PR) data reveal that the storm was still dropping moderate to heavy rain over Australia in an area southeast of the Gulf of Carpentaria.

Just about an hour later, another NASA satellite passed over Yasi capturing the massive size of the strom in a visible image. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies onboard NASA's Aqua satellite captured data on Yasi at 04:15 UTC (Feb. 2 at 11:15 p.m. EST/2:15 p.m. Australia local time. The center of Yasi had already moved inland and the eye of the storm had become obscured by clouds.

The Australia Bureau of Meteorology (ABoM) website has been updating residents of Yasi's movement and affects. To see the ABoM's radar, visit: http://www.bom.gov.au/products/national_radar_sat.loop.shtml.

At 9:30 a.m. EST (14:30 UTC) on Feb. 3 (or 12:30 a.m. Australia local time on Feb. 4) Yasi was approaching the border of the Northern Territory and had weakened into a tropical depression. The ABoM noted that isolated thunderstorms, heavy rains, flash flooding and damaging winds with gusts greater than 48 knots (55 mph/90 kmh) are possible in the western interior of Queensland.

Im Focus: The fastest light-driven current source

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.

Graphene is up to the job

Im Focus: LaserTAB: More efficient and precise contacts thanks to human-robot collaboration

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.

Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...
