Charging Thunderclouds Affect Ionospheric Conductivity

by David Shultz 6 September 20196 March 2023

As thunderstorm updrafts strengthen, electrification of clouds can heat the lower ionosphere, explaining prolonged disturbances to radio waves in the rarefied atmospheric layer.

A “Super” Solution for Modeling Clouds

Aaron Sidder, freelance science writer by Aaron Sidder 6 September 201920 July 2022

Climate models struggle to accurately portray clouds because the models cannot resolve the scales at which clouds form. A new study demonstrates a potential fix for the problem.
