Abstract A new procedure to obtain a longitudinally varying and slowly evolving atmospheric background state for the analysis of Rossby waveguides is described and discussed. The procedure is a rolling zonalization scheme, redistributing Ertel potent

Recently, Nakamura and Huang proposed a theory of blocking onset based on the budget of finite-amplitude local wave activity on the mid-latitude waveguide. Blocks form in their idealized model due to a mechanism that also describes the emergence of t

Weather regimes govern an important part of the sub-seasonal variability of the mid-latitude circulation. Due to their role in weather extremes and atmospheric predictability, regimes that feature a blocking anticyclone are of particular interest. Th

The waveguidability of an upper-tropospheric zonal jet quantifies its propensity to duct Rossby waves in the zonal direction. This property has played a central role in previous attempts to explain large wave amplitudes and the subsequent occurrence

Atmospheric blocking events are high-pressure weather events which block the mid-latitude westerly flow and can last from days to weeks. Owing to their persistence they can lead to extreme surface weather in the affected regions. Until now the larges

Recently, Nakamura and Huang proposed a simplified model of blocking onset in which blocks form due to an obstruction of the zonal propagation of wave activity on the mid-latitude waveguide analogous to how traffic jams emerge on a highway. The theor
