Can I use NWP met data for dispersion modelling?
CERC has been commissioned to carry out an investigation into the use of Numerical Weather Prediction (NWP) met data in atmospheric dispersion modelling. CERC's consultancy and scientific research teams will focus on modelling carried out for planning and permitting under EPR, whilst the UK Health Security Agency (UKHSA) will target probabilistic accident consequence assessments. The project will ...

Decadal SST Variability in the Southeast Indian Ocean and Its Impact on Regional Climate
The southeast Indian Ocean (SEIO) exhibits decadal variability in sea surface temperature (SST) with amplitudes of ∼0.2-0.3 K and covaries with the central Pacific (r= -0.63 with Niño-4 index for 1975-2010). In this study, the generation mechanisms of decadal SST variability are explored using an ocean general circulation model (OGCM), and its impact on atmosphere is evaluated using an ...

Urban flooding caused by climate change: what will be the impacts?
Heavy rain and snow induced by climate change could cause significant damage in urban areas. A recent model study estimates the impact on a Swedish city and suggests there could be an increase in the number of surface floods by 25-45 per cent during this century. Since 1998, floods in Europe have caused some 700 deaths, the displacement of about half a million people and at least EUR 25 billion ...

Exploring air quality model evaluation techniques
Comparisons of modelled and measured data are a key part of evaluating model performance. CERC's latest project for the Atmospheric Dispersion Modelling Liaison Committee (ADMLC) is investigating approaches to air quality model evaluation. A literature review is identifying established and emerging model evaluation techniques and performance metrics for a variety of model types and ...

Geomagnetic storm analysis to improve chemistry climate models
Scientists from the British Antarctic Survey and the Space Weather Prediction Center in Boulder, Colorado, have shown that high energy charged particles that are usually trapped in the Earth’s magnetic field are released into the atmosphere at different locations during geomagnetic storms. The results will help to refine models of atmospheric chemistry and climate. A paper published this month ...

Improving local conditions can improve ecosystem resilience to global changes
Improving local water quality could mitigate the damaging effects of rising CO2 on marine ecosystems, new research suggests. Scientists in Australia found that nitrogen pollution in seawater, when acting in combination with heightened CO2 concentrations, had a significant effect on the growth of turfing algae, which displace kelp forest ecosystems. In today’s world, pressures on ecosystems ...

Study: Volkswagen’s excess emissions will lead to 1,200 premature deaths in Europe
In September 2015, the German Volkswagen Group, the world’s largest car producer, admitted to having installed “defeat devices” in 11 million diesel cars sold worldwide between 2008 and 2015. The devices were designed to detect and adapt to laboratory tests, making the cars appear to comply with environmental standards when, in fact, they emitted pollutants called nitric oxides, ...

Largest Antarctic ice sheet more sensitive to ocean warming than previously thought
The largest ice sheet in the world, the east Antarctic ice sheet, may succumb to climate change faster than thought, according to recent research. Warming ocean currents, triggered by shifting wind patterns, could accelerate melting of the ice sheet, leading to a rise in sea levels, say the researchers. The east Antarctic ice sheet has an average thickness of over 2 km and can reach more than 4 ...

How vulnerable to flooding is New York City?
A report just released in the most recent issue of the Bulletin of the American Meteorological Society offers hope that a new high-resolution storm surge modeling system developed by scientists at Stony Brook University will better be able to predict flood levels and when flooding will occur in the New York metropolitan area, information crucial to emergency managers when planning for impending ...

Advances in Sea-State Forecasting using Chelsea Sensor
Marine operations such as offshore oil and gas operations, renewable energy projects and shipping depend on high quality information on sea-state (wave height, period, direction, steepness) for economic and safety decision making. The information currently available is based on atmospheric/ocean models and lacks sufficient temporal and spatial resolution. “Wave conditions are always ...

Emission Control - Geoengineering to remove Carbon Dioxide from the Air
The notion of global warming was first mooted by French scientist and mathematician Joseph Fourier in 1824 and discovered by John Tyndall in 1860, he and later, Svante Arrhenius, pinned down the mechanisms. It is perhaps deceived wisdom that Arrhenius was the first to suggest that Sweden might once again be able to grow tropical fruit, such as bananas with a little geo-engineering, but Alexander ...

NASA data show some African drought linked to warmer Indian Ocean
A new study, co-funded by NASA, has identified a link between a warming Indian Ocean and less rainfall in eastern and southern Africa. Computer models and observations show a decline in rainfall, with implications for the region's food security. Rainfall in eastern Africa during the rainy season, which runs from March through May, has declined about 15 percent since the 1980s, according to ...

NASA Finds Sea Ice Decline Driving Rise in Arctic Air Pollutants
Drastic reductions in Arctic sea ice in the last decade may be intensifying the chemical release of bromine into the atmosphere, resulting in ground-level ozone depletion and the deposit of toxic mercury in the Arctic, according to a new NASA-led study. The connection between changes in the Arctic Ocean's ice cover and bromine chemical processes is determined by the interaction between the salt ...

Climate studies to benefit from 12 years of satellite aerosol data
Aerosols, very small particles suspended in the air, play an important role in the global climate balance and in regulating climate change. They are one of the greatest sources of uncertainty in climate change models. ESA's GlobAerosol project has been making the most of European satellite capabilities to monitor them. Using data from the Along Track Scanning Radiometer-2 on the ERS-2 satellite, ...
