Regime dependent instability as a transition mechanism in large-scale atmospheric flow
regimes instability baroclinic
2015/9/30
Two apparently distinct approaches to studying the observed low frequency variability in the atmosphere have evolved over the past few years. One approach invokes multiple, recurrent flow regimes to e...
Reuse of Recovered Waste Tail-Gas in a Full-Scale Furnace
Energy Recovery Carbon dioxide Furnace
