The model, called the Nonhydrostatic ICosahedral Atmospheric Model (NICAM), was developed for the supercomputer Earth Simulator at JAMSTEC. Given the atmospheric conditions that were present 1-2 weeks before the observed cyclones formed, the model successfully reproduced the birth of two real tropical cyclones that formed in the Indian Ocean in December 2006 and January 2007.
The model captured the timing and location of the formation of the observed cyclones as well as their paths and overall evolution. "We attribute the successful simulation to the realistic representation of both the large-scale circulation and the embedded convective vortices and their merging," says Hironori Fudeyasu, lead author of the study and IPRC postdoctoral fellow.
Atmospheric computer models with sufficient detail to represent clouds have greatly added to an understanding of local and regional climate, but huge computational needs in the past have allowed these models to be run only for small areas.
"The high temporal and spatial resolution datasets provided by NICAM in this and future simulations will allow detailed studies of tropical cyclone genesis and evolution, as well as other weather and climate-related phenomena," says co-author Yuqing Wang, UH meteorology professor and IPRC research team leader. He believes the results will usher in a new era in weather and climate prediction.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
