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

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

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

Heat waves of the past decade in Chinese mega-cities: a quick review

By Ting Sun Although cities are often already warmer than their rural surroundings (the well-known “urban heat island” effect), heat waves (HWs), excessively hot periods, will not only enhance the urban and rural temperatures but also exacerbate the contrast between … Continue reading
