Chaotic Convection

Posted on 18 December, 2017 by Stephen Burt

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 →

How the Hadley Cells work

Posted on 15 October, 2018 by hjia

By Gui-Ying Yang The Hadley Cell, named after British meteorologist George Hadley who discovered this tropical atmospheric overturning circulation, is one of the basic concepts in weather and climate. Figure 1 shows the zonal mean overturning circulation in a latitude height … Continue reading →
