sulphurous

There was a terrible, sulphurous smell, like rotten eggs, and a tremendous pressure against my chest.

On the superheated surface white streaks ran like lightning in a sulphurous cloud.

A distant but threatening thunder murmur broke from the heart of a bank of sulphurous clouds beating closely over the south.
