Ibn Abbas (ra) made this supplication when he heard a cloud burst:

“Glory be to him whom you glorified.” He said that the thunderclap is an angel who yells at the rainclouds as a shepherd yells at his sheep/goats.

حَدَّثَنَا بِشْرٌ، قَالَ‏:‏ حَدَّثَنَا مُوسَى بْنُ عَبْدِ الْعَزِيزِ قَالَ‏:‏ حَدَّثَنِي الْحَكَمُ قَالَ‏:‏ حَدَّثَنِي عِكْرِمَةُ، أَنَّ ابْنَ عَبَّاسٍ كَانَ إِذَا سَمِعَ صَوْتَ الرَّعْدِ قَالَ‏:‏ سُبْحَانَ الَّذِي سَبَّحْتَ لَهُ، قَالَ‏:‏ إِنَّ الرَّعْدَ مَلَكٌ يَنْعِقُ بِالْغَيْثِ، كَمَا يَنْعِقُ الرَّاعِي بِغَنَمِهِ‏.‏
