Saharan and Asian dust, biological particles end global journey in California

UCSD, NOAA study is the first to show that dust and other aerosols from one side of the world influence rainfall in another

A field study of aerosol impacts on clouds and precipitation in the Sierra Nevada mountains shows that dust and microorganisms transported from as far away as the Sahara desert help to spur the precipitation that California counts on for its water supply.

Study: Reducing human-caused air pollution in North America & Europe brings surprise result: more hurricanes Read more

A new NOAA study published today in the journal Science Advances about four decades of tropical cyclones reveals the surprising result that reducing particulate air pollution in Europe and North America has contributed to an increase in the number of tropical cyclones in the North Atlantic basin and a decrease in the number of these storms in the Southern Hemisphere. The study also found that the growth of particulate pollution in Asia has contributed to fewer tropical cyclones in the western North Pacific basin.
