The differences between the initialized and the uninitialized analyses from the European Centre for Medium Range Weather Forecasts for the December to February and the June to August seasons are examined to determine the extent to which analysed fields are changed by the initialization procedure and to determine if such changes significantly affect diagnostic calculations. The results indicate that, with the exception of the divergent wind and the vertical motion, changes made to the analyses during initialization are small, and are generally only a small fraction of the differences between the objective analyses of independent data producers.

    Over the last years, probability weather forecasts have become increasingly popular due in part to the development of ensemble forecast systems. Despite its widespread use in atmospheric sciences, probability forecasting remains a subtle and ambiguous way of representing the uncertainty related...

    In a weather prediction, information flows from the initial conditions to a later prediction. The uncertainty in the initial conditions implies that such a flow should be quantified with tools from probability theory. Using several recent developments in information theory, this flow is explored...

Theoretical understanding of the inverse error cascade is limited mostly to homogeneous, isotropic turbulence, whereas numerical simulations have focused on highly complex...

Relative humidity seems to play a smaller role than thought before. Atmospheric stability forecasts, projecting...
