What’s the secret of coarse dust?

By Claire Ryder Mineral dust aerosol particles are regularly lifted into the atmosphere in arid regions, such as deserts, and transported over thousands of kilometres by the wind, such as from the Sahara desert to the Caribbean Sea, as shown … Continue reading

On the predictability of European summer weather patterns

By Albert Ossό Forecasts of summer weather patterns months in advance would be of great value for a wide range of applications. However, the current seasonal dynamic model forecasts for European summers have very little skill (Arribas et al. 2011). … Continue reading

Climate change in the Mediterranean Sea

By Fanny Adloff The Mediterranean is the largest semi-enclosed sea on our planet. Acting as a miniature ocean, this basin is appropriate to study climate change impact on the ocean. The residence time of the Mediterranean waters – of about … Continue reading

Estimating the risks of climate change: what are the effects of climate policy?

By Nigel Arnell I am writing this from Beijing, where the 13th National People’s Congress has just reaffirmed the Chinese commitment to control future emissions of greenhouse gases and meet the aspirations of the Paris Agreement on Climate Change. This … Continue reading

Improving estimates of soil moisture over Ghana

By Ewan Pinnington This work aims to improve estimates of soil moisture over Ghana as part of the ERADACS project. In regions where the population relies on subsistence farming it is soil moisture, rather than precipitation per se, that is … Continue reading

A simple way to find out where the moisture for regional rainfall comes from

by Liang Guo Moisture tracing is an interesting scientific topic that has fascinated meteorologists and hydrologists for decades. Methods for tracing moisture are numerous, from observations to numerical modelling, from water isotopes to remote sensing, from online tracking to off-line … Continue reading

Stronger windstorms and higher wind risk in a warmer climate

By Oscar Martínez-Alvarado The most devastating type of winter storms to affect north-west Europe are characterised by a descending jet of air, known as a sting jet, that can result in strong, localised surface winds and wind gusts in a region … Continue reading

Chaotic Convection

By Todd Jones In the traditional global climate model (GCM) configuration, models simulate atmospheric motions explicitly on spatial grids with spacings on the order of 100 km. Motions on finer scales are not directly simulated. Instead, we use parameterizations, some … Continue reading

Impacts of climate variability and change on the energy sector: A case study for winter 2009/10

By Emma Suckling Secure and reliable energy supplies are an essential part of modern economic life. But the national and global infrastructures that deliver energy are changing rapidly in the face of new and unprecedented challenges, including the need to … Continue reading

Exploring the impact of the Atlantic Multidecadal Variability (AMV)

By Dan Hodson After 140 years of observations, we now know that the temperature of the surface of the Atlantic ocean slowly varied over time, cooling and warming over periods of decades (Figure 1). These slow variations in temperature sit … Continue reading
