The Core-cloak Convection Model

By: Jian-Feng Gu Moist convection plays a fundamental role in large-scale circulations and climate, ranging from cumulus clouds smaller than 100m to organized weather systems of several thousands of kilometers. Limited by their grid spacing, numerical models are not able … Continue reading

Balloon measurements at Stromboli suggest radioactivity contributes charge in volcanic plumes

By: Martin Airey Volcanic lightning is an awe-inspiring and humbling display of nature‚Äôs power. It results from the breakdown of large electric fields that are generated within the volcanic plume. The processes that result in the accumulation of charge are … Continue reading

Multi-fluids Modelling of Convection

By: Hilary Weller Atmospheric convection – the dynamics behind clouds and precipitation – is one of the biggest challenges of weather and climate modelling. Convection is the driver of atmospheric circulation, but most clouds are smaller than the grid size … Continue reading
