Time scales of atmospheric circulation response to CO2 forcing

Posted on 17 July, 2017 by Stephen Burt

By Paulo Ceppi An important question in current climate change research is, how will atmospheric circulation change as the climate warms? When simulating future climate scenarios, models commonly predict a shift of the midlatitude circulation to higher latitudes in both … Continue reading →
