The position of the polar front jet stream over North America would be best predicted by
A)a numerical forecast model with a small domain.
B)a numerical forecast model with a large domain.
C)a parameterization within a numerical forecast model with a small domain.
D)a grid representation within a numerical forecast model with a small domain.

Question

Quizplus · Accepted Answer

The position of the polar front jet stream over North America is influenced by large-scale atmospheric features, such as the location of high and low-pressure systems and the position of the polar front itself. To accurately predict the position of the jet stream, a numerical forecast model with a large domain would be better as it can take into account the larger-scale features that influence the jet stream's movements. A small domain model may not capture these features, leading to less accurate predictions.
