Study reveals ways to improve systems using new weather technology

17.10.2006
Human factors/ergonomics researchers at three universities are working to ensure that improved weather radar data gathered through the Collaborative Adaptive Sensing of the Atmosphere (CASA) project will help emergency managers make faster, more accurate, and more confident decisions about approaching severe weather.

The researchers will present the findings of their study at the Hilton San Francisco Hotel on Thursday, October 19, 2006, during the HFES 50th Annual Meeting, October 16–20.

Since the 1990s, the weather community has used a network of 158 nationwide Doppler radars to observe the atmosphere. Emergency managers are usually glued to these screens so they can predict approaching major weather systems. There are limitations to the Doppler radar, however; low-altitude areas where severe weather strikes the hardest--the Gulf Coast, for example – are extremely undersampled.

CASA radars can detect weather systems lower to the ground, more frequently, with shorter ranges, and with finer spatial and temporal resolution. Four CASA radars covering a 100 x 100-kilometer testing area in Oklahoma will be up and running in late 2006. To determine the impact of this improved data, the researchers first created a model of how emergency managers make decisions. Then they asked 11 experienced emergency managers to make decisions about two simulated severe weather scenarios and to complete questionnaires based on their techniques, experiences, and observations following the simulations.

This study helped the researchers refine the decision-making model by revealing difficulties that the emergency managers encountered. For example, many did not understand the relationship between radar location and storm velocity data, and some became distracted by the fine-grained details and lost the "big picture" perspective. These findings will aid in the design of improved training and better visualizations of the data.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
