For Critical Marine Low Clouds, a Research and Observation Plan
Nov 28, 2016       
Marine low clouds hover in the lowest couple of kilometers above the world’s oceans. They produce little but drizzle, and could never match their deeper mid-continent cousin clouds for dramatic weather and severe storms. But marine low clouds are vastly important to the world’s climate and energy balance. They are a major determinant of the [...]

Amazon Study: Rainstorms Carry Particles Needed to Make Clouds
Oct 24, 2016       
Understanding how tiny particles emitted by cars and factories affect Earth's climate requires accurate climate modeling. Scientists also need to quantify the effects of these pollutant particles compared to particles naturally present in the atmosphere. One large uncertainty remains: What Earth was like before industrial-era emissions began? In a paper published today in Nature, scientists in [...]

To Tighten Climate Models, a Livermore Team Investigates the Land-Cloud Interface
Aug 22, 2016       
You might say that Yunyan Zhang, a climate scientist at Lawrence Livermore National Laboratory, was born to her work. In her native China, the first syllable of “Yunyan” means “cloud,” and the second “Canadian geese,” the migratory birds that take to the sky in V-shaped formations. In a scientific way, Zhang took to the sky early. [...]

Atmospheric System Research Sponsored Workshop on Absorbing Aerosols
May 26, 2016       
Light-absorbing aerosol particles contribute substantially to the net uncertainty in aerosol forcing of climate, despite their small abundance compared to non-absorbing aerosol particles.  Their importance and influence on climate is directly linked to their ability to absorb solar energy, subsequently heating the atmosphere and, depending upon their vertical distribution, affecting atmospheric dynamics and cloud formation [...]

Atmospheric Convection Workshop Held
May 20, 2016       
Atmospheric moist convection is a primary process through which much of the heat from the surface of the Earth is transported to the upper troposphere. This process starts out with the formation of small shallow clouds that rise from the boundary layer, which under the right environmental conditions grow into deep thunderstorms that produce rain. These [...]
