Rainstreaked

Rainstreaked is an adjective used to describe surfaces that have been marked by the passage of rainwater, typically appearing as lines or streaks. This effect is commonly observed on windows, walls, and pavements after a rain shower. The streaks are formed as rainwater, containing dissolved minerals, dust, or pollutants, runs down a surface and evaporates, leaving behind these distinct markings. The appearance of rainstreaks can vary depending on the cleanliness of the surface and the composition of the rainwater. In some contexts, rainstreaked can be used metaphorically to evoke a sense of melancholy or the passage of time, as the marks suggest exposure to the elements and weathering. For instance, a rainstreaked landscape might imply a place that has endured many storms. The term is descriptive and focuses on the visual evidence left by rain.
