The phenomenon describes objects or substances unexpectedly descending from the atmosphere. Instances range from precipitation, such as rain and snow, to more unusual occurrences like the deposition of debris or even biological matter. For example, reports have detailed cases of fish or frogs appearing to drop from above, despite the absence of immediate bodies of water.
Understanding these events is important for various reasons. Meteorologists can analyze unusual precipitation to study atmospheric conditions. Investigating the appearance of debris from above aids in identifying potential hazards like aircraft malfunctions or space junk reentry. Documenting these events also offers insight into rare atmospheric phenomena and their potential impact on the environment.
