Cosmological simulations are a cornerstone of our understanding of the Universe during its 13.7 billion year progression from small fluctuations that we see in the cosmic microwave background to today, where we are surrounded by galaxies and clusters of galaxies interconnected by a vast cosmic web.
Simulations of the formation of structure in the Universe typically simulate dark matter, a collisionless fluid, as a discretized set of particles that interact only gravitationally.
Atmospheric Dispersion of Radioactivity from Nuclear Power Plant Accidents: Case Study for the Eastern Mediterranean and Middle East.
We estimate the contamination risks from the atmospheric dispersion of radionuclides released by severe nuclear power plant accidents using the EMAC atmospheric chemistry–general circulation model at high resolution (50 km). We present an overview of global risks, and also a case study of nuclear power plants that are currently under construction, planned and proposed in the Eastern Mediterranean and Middle East, a region prone to earth quakes.
Modeling the global atmospheric dispersion and deposition of radionuclides released from the Fukushima Dai-ichi nuclear power plant accident.
The EMAC atmospheric chemistry – general circulation model was used, with circulation dynamics nudged towards ECMWF ERA-Interim reanalysis data. We applied a resolution of approximately 0.5 degrees in latitude and longitude. The model accounts for emissions and transport of the radioactive isotopes 131I and 137Cs, and removal processes through precipitation, particle sedimentation and dry deposition.
From local air pollution to global change in one century.
We modeled air pollution plumes from 35 major population centres during the past century. The animation produced shows the atmospheric emission and transport of a 10-day lifetime tracer, scaled to CO emissions and population growth.
It is meant to convey the rapid expansion of population living in cities during the 20th century and that megacity air pollution is not any more a local phenomenon but rather one which has global impact.
Atmospheric dispersion and fallout from the Mari ammunition explosion on 11 July 2011.
Research scientists at The Cyprus Institute have computed the atmospheric dispersion of debris from the Mari ammunition explosion on 11 July, 2011, using the Weather Research and Forecasting (WRF) model. A high-resolution computational model of the atmosphere (3x3 km resolution) was used together with meteorological observations, starting at 6am local time. The explosion cloud was computed by initializing the explosion aerosol plume up to a height of 5.
