Säänlukua

Säänlukua is a Finnish term that translates directly to "weather number." It refers to a numerical system used in some Finnish weather forecasting and reporting contexts to represent specific weather conditions. This system is not a universally standardized meteorological code but rather a localized or sometimes historical method of simplifying complex weather descriptions into digestible figures.

The specific meaning of each "säänlukua" can vary depending on the context or the issuing authority. Typically, these numbers might correspond to a combination of factors such as temperature range, precipitation type and intensity, wind speed, and cloud cover. For instance, a low number might indicate clear and calm conditions, while a higher number could signify severe weather like heavy snow or strong winds. The precise definition of each number would usually be provided alongside the forecast or in a legend accompanying weather maps or reports.

While modern weather forecasting increasingly relies on detailed textual descriptions and graphical representations, "säänlukua" may still be encountered in older records, local traditions, or specific niche applications where a quick, categorical understanding of the weather is desired. Understanding the specific "säänlukua" system in use requires knowledge of its origin and the definitions associated with each number. It serves as a shorthand, allowing for rapid communication of general weather patterns.
