Pioneering Measures of Low Marine Clouds
Jun 25, 2018 [ Program News ]       
An ASR science team is ‘poised to reinvent our sense of stratocumulus clouds’ Mark Miller is a Rutgers University professor of meteorology who studies the atmosphere’s boundary layer, the turbulent first kilometer of the atmosphere where most weather happens. In 1989, he was a student at Pennsylvania State University when he traveled to the Azores with his [...]

LASSO Helps Rope In the ‘Cloud Problem’
Jun 25, 2018 [ Program News ]       
Graham Feingold and other theoreticians use the new tool to test model parameterizations To some of us, “lasso” refers to a stiff loop of rope handy for throwing. To statisticians, it is a way of doing regression analysis. For atmospheric scientists who develop and test models, however, LASSO is a new way to throw a noose around [...]

‘One of the Most Fun Things’
Jun 11, 2018 [ Program News ]       
After a long and varied science career, ASR Program Manager Ashley Williamson is poised to move on North of Columbus, Georgia, the hill country of the Piedmont plateau slopes southward into flat coastal terrain along the Chattahoochee River. Not far away are a series of deep chasms known as the state’s “Little Grand Canyon.” It’s pretty country, [...]

Low Clouds Over Land and Sea
May 25, 2018 [ Program News ]       
For nearly a decade, one lab project has dug into the details of the hard-to-predict boundary layer We all experience weather—the rain, wind, and sliding temperatures that color our daily lives. Our weather happens in the boundary layer, the lowest few kilometers of Earth’s atmosphere. Since 2009, the boundary layer and its clouds, precipitation, and patterns of [...]

A Great Plains Divide
May 25, 2018 [ Program News ]       
Set of papers investigates temperature differences between models and observations A new group of four papers published in Journal of Geophysical Research: Atmospheres explores why earth system models simulate warmer surface temperatures than ground-based observations show in the central United States. The papers, led by authors from Lawrence Livermore National Laboratory and the U.K. Met Office, focus on results [...]

When a Maritime Continent Gets in the Way
May 25, 2018 [ Program News ]       
ASR scientists will gather data on Madden-Julian Oscillation events Oregon storms and Sri Lankan cyclones bear a common signature—a cyclical churning of clouds and rain the size of Alaska called the Madden-Julian Oscillation (MJO). This slow-moving weather pattern travels from the Indian Ocean to the Pacific every 30 to 60 days, but sometimes weakens over an [...]

Data Reveal Smoke Aerosol Presence Higher Than Previously Believed
May 25, 2018 [ Program News ]       
Particles causing atmospheric changes are common in mid-Atlantic boundary layer Southern Africa is among the world's largest emitters of biomass-burning aerosols (tiny particles in the air). Their westward transport over the remote southeast Atlantic Ocean colocates some of the largest atmospheric loadings of absorbing aerosols with the least examined of the Earth’s major subtropical stratocumulus decks. Now, [...]

On the Way: A Better Analysis of Ice in Clouds
Feb 26, 2018 [ Program News ]       
A project aims to improve how ice cloud microphysics is represented in models The clouds we see every day are composed of water and ice. Microphysical processes govern the many ways cloud-making water drops and ice particles grow, shrink, stick together, break up, and fall. In turn, cloud microphysics influence the atmospheric dynamics that create clouds [...]
