Names that mean natural occurring phenomenon?

I am writing a script in which I derive a lot of elements from Final Fantasy. In Final Fantasy The main characters are named after natural occurring phenomenon, or their names mean natural occurring phenomenon i.e Terra, Cloud, Squall, Laguna, Raina, Tidus, Yuna... Please help I need names! some examples are luna means moon, alan means rock stuff like that, or cool sounding phenomenon's like cloud or squall.
