In this case, a large part of Europe has been subjected to a harsh winter, due to an Eastern flow of Siberian origin associated with a blocking anticyclone
in high latitudes on the North Atlantic that has displaced the westerly winds, the jet stream of tropospheric high levels and associated storms and fronts towards lower latitudes.
In such situation, errors might occur when predicting the weather in Europe upon the cyclone moving eastward or a blocking anticyclone appears in front of it, which blocks the way.

Previous studies of blocking anticyclone lifecycles have shown that boundary layer friction was one of the primary forcing mechanisms in the decay process.

The blocking anticyclone

The influx of latent heat in the block area could contribute to the energy supply of the blocking anticyclone
and prolong its existence.
However, in the absence of a clear theory explaining this, most modelers would not feel especially confident in such a result, especially as the CMIP models do not simulate long-lived blocking anticyclones
with any degree of realism (Masato et al 2013), and even models with higher atmospheric resolution still suffer large biases in Euro-Atlantic blocking (Schiemann et al.
