New research suggests that sea-salt aerosols seed large raindrops that starve clouds of water needed to make lightning. But not all scientists are convinced it’s simply about salt spray.
Recent advances in measurements and models are paving the way to transform fundamental understanding and simulation of ice-nucleating particles and their climate impacts.
New measurements show the macro- and microphysical characteristics of the clouds and precipitation over the data-space regions of the Southern Ocean.
International regulations have reduced aerosol pollutants released from ships. Now, researchers want to use ship tracks to better understand the ambiguous effects that cleaner air has on climate.
A new-generation weather radar and a massive supercomputing system enables forecasts of storms refreshed every 30 seconds, a significant development in severe weather prediction.
Insects that eat plant leaves could change the local atmosphere, but current climate models do not account for this impact.
Researchers present a new approach to modeling the stochastic mixing process of convection using a machine learning technique.
Rain and cloud droplets are treated as distinct categories in most models yet lie on a continuous droplet size spectrum in nature. Representing them as part of a continuous spectrum improves models.
Altitude-resolved S-band radar observations of graupel are used to decipher thunderstorm ground enhancements in surface electric field and gamma ray flux.
Models with smallest feedback errors are found to have moderate cloud feedbacks and equilibrium climate sensitivity of 3 to 4 degrees of warming when the concentration of carbon dioxide is doubled.
