weathersuch

Weathersuch is a term used in meteorology and climate communication to denote a weather scenario that closely resembles a previously observed situation. The concept is not an official forecast category but a descriptive label applied in analytical discussions, forecasting dashboards, and educational materials to highlight analogs between current atmospheric conditions and past events.

Origin and usage: The coinage combines weather with the demonstrative "such" to indicate similarity to known events. It emerged in informal discussions among researchers and educators as a way to convey forecast confidence without relying solely on numerical probabilities.

Applications: In practice, a meteorologist might say that the current synoptic setup is "weathersuch" for a heavy rain event, meaning the present pattern matches past heavy rainfall episodes. It supports narrative communication, but it is complemented by quantitative methods such as ensemble forecasts, analog modeling, and machine learning.

Limitations: Because "weathersuch" depends on historical analogs, its reliability is limited by the representativeness of the past record and the non-stationary nature of climate systems. It should not replace probabilistic forecasts.

Relationship to related concepts: Weathersuch is akin to historical analog forecasting and pattern recognition, but is less formalized than formal analog indices. It can be used as a mnemonic or education tool to illustrate potential outcomes.
