There are a lot of good idiomatic phrases in English for rain:
The rain pitter-pattered on the roof top.
"Pitter-patter" means light sounds or beats, and often is used to describe the sound of small animals (like cats) as they gently move about. It has a fairly positive and easy-going connotation, and using "pitter-patter" to describe rain invokes a sense of melody and calm.
The rain sprinkled on the roof top.
"Sprinkle" means scattering or dispersing. It generally is applied to small objects, like dust or sugar coatings. When describing rain, it generally implies that the rain drops are small and gentle. It can imply a feeling of spreading in a haphazard or unguided way. For this reason, it has a fairly neutral connotation, generally meaning light rain.
The rain showered the roof top.
"Shower" means a lot of water, should evoke the feeling of being in a shower. It creates a sense of a large quantity of water, coming down in large drops. It's not necessarily aggressive or negative, but implies lots and lots of water. A "shower" of water on the roof wouldn't be resolvable in individual drop sounds, but would instead be a steady drone of noise.
The rain pelted the roof top.
"Pelt" means to attack with objects. Here, it should evoke a sense of anger or aggression, as if the water were throwing itself in attack at the roof. "Pelting rain" would be large, fast drops, coming down hard.
The rain battered the roof top.
"Batter" means to beat or attack. Generally, it always evokes a sense of aggression and violence. When used with rain, it often implies a type of windy rain, as the wind and the rain "work together" to attack the building. In the minds eye, you might see shutters banging about and hear the whistling of the wind when you imagine "battering rain".
There are a lot more phrases, but these should get you going. If you are looking for a more specific connotation, I'll see what I can come up with.
I found a surprising theme as I whittled down the edit to a few hundred photos, then to a few dozen, and finally to the 25 we have now. I expected rays of sunshine, bright colors, and puddle stomping. But the images that seemed to speak the loudest had something unexpected in common: They were so quiet.
After the rain, as people and animals gently step back out into the world, is an amazing time for quiet beauty. There are certainly exceptions in this story, but the overwhelming nature of these photos changed the way I thought about this theme. The winds die down, the song of raindrops fades away, and we are left in a world that seems calmer than before.
To the thousands of you who shared so many powerful scenes from our world after the rain, thank you. There were also some rule breakers out there, like Marc Jones’s photo that broke the rules in a beautiful way. For other photos, I could not confirm the time they were taken, the level of rain, or how long ago the storm had ended, but if the mood felt right, that was fine by me.
