What's your new view on the weather forecast?

Long-term prediction of space-time scale often emphasizes the adjustment process of large-scale long-term circulation, such as ultra-long waves, while ignoring the role of short-term circulation jump and mutation in sub-scale. When choosing circulation correlation, we often emphasize "seasonal correlation" and "semi-annual effect" and pay less attention to the special effect of circulation adjustment transition period; Only the size of correlation coefficient is considered, while the special functions of some special related fields are ignored. When calculating the circulation correlation zone, only the independence of factors is emphasized, which often destroys the combinatorial correlation of the whole circulation structure.
