Buddhism has its roots in a hot country where sunshine was seen as much a problem as a blessing, and so Buddhist metaphors tend to focus more on rain. In the Flower Ornament Scripture (the Avatamsaka) we’re told:

The supreme water spirit Ocean covers the earth with clouds; the rain in each place is different, but the spirit has no thought of distinction. Likewise, Buddha, sovereign of truth, extends clouds of great compassion in all directions, raining differently for each practitioner, yet without discriminating among them. Source: Wildmind
