Adding atmospheric effects to your renders can be something of a challenge, both in terms of your workflow and speed. You can use volumetrics for creating fog and mist, or particles for rain and so on, but that might not always be the best solution.
You can of course add rain this way and there are benefits like true depth in the scene, although this comes at the expense of slower rendering times and a much longer workflow, as well as dealing with bigger file sizes. If the rain isan acceptable price, but in many cases it's a background element that's there to give a sense of the environment; subtle and less in need of total realism.
