How Clouds Make Something Out of Nothing


 
Results from a study of clouds and aerosols conducted in the Azores revealed that new particles can seed the formation of clouds in the marine boundary layer the atmosphere up to about a kilometer above Earth s surface even over the open ocean, where the concentration of precursor gases was expected to be low.

New results from an atmospheric study over the Eastern North Atlantic reveal that tiny aerosol particles that seed the formation of clouds can form out of next to nothingness over the open ocean. This “new particle formation” occurs when sunlight reacts with molecules of trace gases in the marine boundary layer, the atmosphere within about the first kilometer above Earth’s surface. The findings, published in the journal Nature Communications, will improve how aerosols and clouds are represented in models that describe Earth’s climate so sci ....

Trace Gases Can Be Formed From Aerosol Particles That Seed Clouds


Close
A study conducted in the Azores on clouds and aerosols has found that new particles can seed the information from the marine boundary layer.
That is the atmosphere up to about one kilometer above the earth s surface. Even on the open ocean where precursor gas concentration was expected to be low.

The Study
Tiny aerosol particles that seed the information of clouds can form out of nothing over the open ocean, a new atmospheric study over the Eastern North Atlantic has revealed.
The formation of the new particles occurs when sunlight reacts with molecules of trace gases in the marine boundary layer. That is the atmosphere within the first kilometer above the earth s surface.  ....

New results from an atmospheric study over the eastern North Atlantic reveal that tiny aerosol particles that seed clouds can form out of next-to-nothingness over the open ocean.
This “new particle formation” occurs when sunlight reacts with molecules of trace gases in the marine boundary layer, the atmosphere within about the first mile above Earth’s surface. The findings will improve how aerosols and clouds are represented in models that describe Earth’s climate so scientists can understand how the particles ....
