I wonder how 2013/2014 and 2014/2015 were able to keep the same general pattern throughout 80% of the winter.
Was the MJO in the COD the entire time? I don't think it could have been completely static.
Seems that some METS believe we warm up big time after mid month. Is this completely based on the MJO progression?
Trying to decipher the reason why this year cannot parallel those years and stay with the current pattern.
