AB: Thunderclouds commonly produce intracloud lightning as a result of the balanced content of the main cloud charges, and cloud-to-ground lightning as a result of charge imbalances developing in the storm. Thunderclouds also produce upward lightning discharges in the form of blue jets and gigantic jets. The present study is based on a combination of recent observations of upward discharges and computational studies of storm electrodynamics, supported by numerical simulations of the discharges using a stochastic lightning model. The results indicate that the mechanisms by which blue and gigantic jet discharges escape from clouds are similar to those of cloud-to-ground lightning.
