One commonly used way to improve a numerical model forecast is to:
A) simplify the model's assumptions.
B) eliminate portions of the model that aren't contributing to the forecast.
C) statistically assess errors that the model makes repeatedly and adjust the forecast accordingly.
D) reformulate the model after every forecast to correct errors.

Question

Statistically assessing errors that the model makes repeatedly and adjusting the forecast accordingly is a commonly used way to improve a numerical model forecast. This allows for the model to learn and adjust its predictions based on past mistakes, resulting in more accurate forecasts over time. Simplifying the model's assumptions or eliminating portions of the model may lead to oversimplification and inaccurate forecasts, while reformulating the model after every forecast may be inefficient and time-consuming.
