FORECAST LEAD TIME [2 records]

Record 1 2022-10-17

English

Subject field(s)
  • Meteorological Forecasting, Data Measurement and Analysis

Ensemble forecasting is useful for improving average forecast accuracy, suggesting a range of possibilities and their probability, estimating the decay of forecast skill as a function of forecast lead time, and even suggesting where extra observations could be targeted.

Domaine(s)
  • Prévisions météorologiques et mesure et analyse des données
CONT

La prévision d'ensemble est une méthode de prévision numérique qui vise à appréhender et quantifier l'incertitude inhérente à toute prévision météorologique. La prévision d'ensemble ne cherche pas à fournir une unique prévision déterministe, mais un ensemble de scénarios dont les variations sont représentatives de l'incertitude liée à la prévision de l'état de l'écoulement atmosphérique.

OBS

The Center for Ocean-Land-Atmosphere Studies(COLA), located in Calverton, Maryland, is a unique institution which allows earth scientists from several disciplines to work closely together on interdisciplinary research related to variability and predictability of Earth's climate on seasonal to decadal time scales. The scientific premise for research at COLA is that there is a predictable element of Earth's current climate that makes it possible to accurately forecast climate variations. While the chaotic nature of the global atmosphere is known to impose a limit on the predictability of the state of the climate at a given instant, the hypothesis behind COLA's research suggests that there is predictability in the midst of chaos, and that accurate climate forecasts with lead times longer than the inherent limit of deterministic predictability are possible.
