    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 scientists to study the physical processes in our atmosphere. By following the sea salt that is evaporated from the ocean, you can see the storms of the 2017 hurricane season. During the same time, large fires in the Pacific Northwest released smoke into the atmosphere. Large weather patterns can transport these particles long distances: in early September, you can see a line of smoke from Oregon and Washington, down the Great Plains, through the South, and across the Atlantic to England. Dust from the Sahara is also caught in storms sytems and moved from Africa to the Americas. Unlike the sea salt, however, the dust is removed from the center of the storm. The dust particles are absorbed by cloud droplets and then washed out as it rains.

    Advances in computing speed allow scientists to include more details of these physical processes in their simulations of how the aerosols interact with the storm systems.

    This may be of interest especially the dust storm around Ophelia

    Net Zero means we are paying for the destruction of our economy and society in pursuit of an unachievable and pointless policy.

    It's cool. look out for the smoke plumes from those giant west coast wildfires, on a few occasions they reach all the way across the Atlantic and cover Ireland and the UK.

    On those days the moon appeared orange as it was low in the sky on the west because of the amount of smoke in the air from those fires.

    I was drawing straw at the time when that happened this year and the whole of county wexford was covered in a smoke haze.
    I hadn't a clue where it was coming from but I knew it was a smoke haze.
    So the good oul internet. I looked up earth nullschool and I was able to track the smoke /aerosols on that back to the wildfires in the U.S.

    The age of instant information.:D
