I remember the word to be no English. I once have seen this word on a website which I don't recall the address.
maybe you're thinking of :
A sunshower or sun shower is a meteorological phenomenon in which rain falls while the sun is shining.1 A sunshower is usually the result of accompanying winds associated with a rain storm sometimes miles away, blowing the airborne raindrops into an area where there are no clouds. Hence, a sunshower. Sometimes a sunshower is created when a single rain cloud passes overhead, and the Sun's angle keeps the sunlight from being obstructed by overhead clouds.
