Summertime in northern Australia means monsoon storms -- and plenty of them. Tall, turbulent clouds associated with these storm systems form rapidly, release their energy in the form of rain, then tail away, leaving in their wake a surplus of moisture to feed the next system. This lifecycle--the formation of tropical convective clouds, their outflow into cirrus clouds, and eventual dissipation into water vapor--is a key component of tropical climate. However, the cloud properties and the extent of their impact on the environment are not well understood or well represented in computer models that are used to simulate climate change.
This week, a team of more than 25 international cloud climate scientists are conducting a three-day operations and planning simulation at Sandia National Laboratories in Livermore, California, to prepare for a complex experiment that will result in the most detailed data sets ever collected for tropical convection. Led by scientists from the U.S. Department of Energy’s Atmospheric Radiation Measurement (ARM) Program and the Australian Bureau of Meteorology (BOM), the Tropical Warm Pool International Cloud Experiment will take place in the region around Darwin, Australia, between January and February 2006.
Darwin is home to one of the ARM Program’s permanent research sites, equipped with a sophisticated array of remote sensing instruments to collect the continuous measurements needed to improve computer models that simulate clouds and climate. The upcoming experiment will include an unprecedented network of ground-based instrumentation, a ship operating off the coast near Darwin, and a fleet of low-, middle- and high-altitude aircraft for in-situ and remote-sensing measurements. Aircraft measurements taken during the experiment will be valuable for validating and improving existing ground-based measurements from the ARM site in Darwin, as well as satellite observations obtained by the National Aeronautics and Space Administration (NASA).

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
