The fundamental problem with numerical weather prediction include the uncertainty with the initial data and resulting initial conditions, the forecast methods used to produce the forecast, and the resulting forecast. The smaller oval about the initial conditions reflects inexact knowledge and the larger ellipse about the forecast shows the error growth. Thus we know more about the .
