How well do the 00 UTC NWP analyses agree with the observational data? Select the correct option.
The correct answer is B.
The initial conditions, represented by the 00 UTC forecast, capture the stable conditions in the surface pressure chart, the moisture conditions in the cross-section, and the low-level calm winds in the wind profile. Since the analysis does a good job of representing conditions at 00 UTC, we can have good confidence in the model forecasts.
