weatheran

Weatheran is a term used in speculative meteorology and in some climate-themed literature to denote a defined profile of atmospheric conditions for a given location and period. It is not a standard term in official meteorology, but rather a coined concept used to describe how a location’s typical weather behaves over time.

Definition and scope: A weatheran describes the typical or expected weather characteristics—temperature range, precipitation probability, humidity, wind tendencies—represented as a composite or vector that characterizes the local climate regime. It serves as a shorthand for summarizing how a place commonly behaves weather-wise.

Computation and components: A weatheran can be summarized as an index or set of indicators derived from climate normals, seasonal anomalies, and variability. In practice, it is often divided into components such as a thermal weatheran (temperature-focused), a hydrological weatheran (precipitation and moisture), and a dynamic or wind weatheran (movement and atmospheric patterns).

Applications and limitations: Applications are mainly educational and fictional: it helps illustrate how different regions differ in their seasonal behavior and how climate change may shift a region’s typical profile. It is not an official meteorological term and has no standardized calculation or forecasting use in professional weather services.

History and usage: The term has appeared in a small corpus of writings since the early 2000s and remains largely informal, with definitions varying by author. It is most often encountered in speculative or pedagogical contexts rather than in practice.
