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

High speed mathematics: reducing the computation time for weather forecasting

By Sarah Dance Several times a day, around 10 million observations of the atmosphere are processed by operational weather services, in order to produce the next weather forecast. At the University of Reading, we have been using mathematics to understand … Continue reading

Biomass burning in South America: Impacts on the regional climate

By Gillian Thornhill Deforestation in south America has many environmental impacts, including loss of habitat, soil erosion, changes to the water cycle and the reduced capacity of the CO2 sink the vegetation provides. Where the vegetation is burned, an additional … Continue reading

Bali volcanic eruption: Research to help reduce flight disruption caused by ash clouds

By Helen Dacre and Andrew Prata The volcanic ash clouds released into the atmosphere by Mount Agung in Indonesia late last year brought back memories of the 2010 eruption of Eyjafjallajökull in Iceland, which caused chaos for holidaymakers in Europe. … 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
