An international team of researchers has uncovered the reason that less lightning occurs over tropical oceans than over land. In their paper published in the journal Nature Communications, the group describes their multi-year ...
As the COVID-19 virus continues to spread around the globe, studying aerosol and droplet transport within different environments can help establish effective, physics-informed measures for virus mitigation. One of the most ...
