WebMar 23, 2024 · An ensemble weather forecast is a set of forecasts that present the range of future weather possibilities. Multiple simulations are run, each with a slight variation of its initial conditions and with slightly perturbed weather models. These variations represent the inevitable uncertainty in the initial conditions and approximations in the models. WebApr 10, 2024 · Although the procedure developed by Linker et al. [14] originally considered deterministic weather forecasts, it was later extended to consider an ensemble of weather forecasts, leading to a stochastic model-based optimization scheme, which was illustrated via simulations with the model DSSAT-CROPGRO [18]. The objective of the present …
