Säänilmiö

Säänilmiö is a Finnish term that translates to "weather phenomenon." It broadly refers to any observable event or process that occurs in the Earth's atmosphere. This encompasses a vast range of occurrences, from the familiar to the extreme.

Common säänilmiöt include precipitation in its various forms such as rain, snow, sleet, and hail. Wind, which is the movement of air, is another fundamental säänilmiö. Temperature variations, including heatwaves and cold spells, are also considered säänilmiöt. Cloud formation, fog, and mist are visual manifestations of atmospheric moisture.

More dramatic säänilmiöt include thunderstorms, characterized by lightning and thunder, and severe weather events like tornadoes, hurricanes (or typhoons), and blizzards. Optical phenomena such as rainbows, halos, and aurora borealis (northern lights) are also categorized as säänilmiöt. The study and classification of these phenomena are central to meteorology, the science of weather. Understanding säänilmiöt is crucial for predicting weather patterns, assessing risks, and developing strategies for adaptation and mitigation in relation to climate.
