[1] In spring 2002, the ALADIN cycles have experienced a tremendous jump in their numbering: cycle 15 was phased directly to 25T1, meaning 10 ALADIN cycles created in only 2 months !.. More seriously, this jump is simply due to the new rule, which states that the ALADIN cycles should have the same numbering than their ARPEGE counterpart.
