Study: Interactions between smoke and clouds have unexpected cooling effect

Atomspheric physicists have found that the way wildfire smoke from Africa interacts with clouds over the Atlantic Ocean results in a net cooling effect, which is contrary to previous understanding and has implications for global climate models. CREDIT NASA/Kirk Knobelspiesse Clouds play a prominent role in moderating Earth’s climate, but their role is still poorly…

Study: A barrage of viruses and bacteria is falling from the sky

New research may explain why genetically identical viruses are often found in very different environments around the globe. An astonishing number of viruses are circulating around the Earth’s atmosphere – and falling from it – according to new research from scientists in Canada, Spain and the U.S. The study marks the first time scientists have…

Even the Tiniest Aerosol Particles Can Kick Up a Storm

From the AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE A new study suggests that tiny aerosol particles from pollution plumes have a greater influence on stormy weather over pristine regions of the world, such as oceans and large forests, than previously believed. Because water cycling in these areas contributes substantially to global weather patterns, the human-made…

Another climate feedback found: ‘cooling effect of natural atmospheric particles is greater during warmer years’

  From the University of Leeds and the “settled science” department, comes this new idea that combines measurements with a model. Understanding the climate impact of natural atmospheric particles An international team of scientists, led by the University of Leeds, has quantified the relationship between natural sources of particles in the atmosphere and climate change.…

Fantastic visualization of Earth’s atmosphere in 2017

How can you see the atmosphere? By tracking what is carried on the wind. Tiny aerosol particles such as smoke, dust, and sea salt are transported across the globe, making visible weather patterns and other normally invisible physical processes. This visualization uses data from NASA satellites, combined with mathematical models in a computer simulation allow…

Aerosols strengthen storm clouds, according to new study

From the UNIVERSITY OF TEXAS AT AUSTIN An abundance of aerosol particles in the atmosphere can increase the lifespans of large storm clouds by delaying rainfall, making the clouds grow larger and live longer, and producing more extreme storms when the rain finally does come, according to new research from The University of Texas at…
