Atmospheric scientists fires resolve ice question climate models
2020/9/4
When fossil fuel or biomass burns, soot -- also known as black carbon -- fills the air. Black carbon is an important short-term climate driver because it absorbs solar energy and can affect the format...
Six million years ago, atmospheric shifts led to increased diversity of grassland mammals（图）
Six million years ago atmospheric shifts grassland mammals
2019/10/30
Six million years ago, grass-eating mammals became more diverse in South America. Shifts in tropical atmospheric circulation known as Hadley circulation led to changes in climate and vegetation, espec...

Sea-spray aerosols are the predominant absorbers and scatterers in the oceanic and unpolluted coastal environment and thereby greatly determine the visibility. Over the last decades, a multitude of fi...
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...
