'Thunderings' in the Bible

Pray to Yahweh; for there has been enough of mighty thunderings and hail. I will let you go, and you shall stay no longer."

All the people perceived the thunderings, the lightnings, the sound of the trumpet, and the mountain smoking. When the people saw it, they trembled, and stayed at a distance.

Yes, can any understand the spreading of the clouds, and the thunderings of his pavilion?
