It is God who determines if the land is made fruitful by rain and dew or flooded and frozen by thunderstorms and frost.
Job 38:25-30 (KJV)
25 Who hath divided a watercourse for the overflowing of waters, or a way for the lightning of thunder;
26 To cause it to rain on the earth, where no man is; on the wilderness, wherein there is no man;
27 To satisfy the desolate and waste ground; and to cause the bud of the tender herb to spring forth?
28 Hath the rain a father? or who hath begotten the drops of dew?
29 Out of whose womb came the ice? and the hoary frost of heaven, who hath gendered it?
30 The waters are hid as with a stone, and the face of the deep is frozen.
