English abstract:
Since the 1980īs it is very well known that the El Ni ̃no Southern Oscillation (ENSO)event involves a large atmospheric excitation that induces changes of the Earth rotation rate at inter annual scales. In return, ENSO is the trigger of atmospheric teleconnections affecting the global atmospheric circulation. In this work we analyze the regional behavior of the anomalies in the motion terms of the axial component of the Atmospheric Angular Momentum (AAM) taking into account the teleconnections between the ENSO 2015-16 event and other expected regional phenomena. In this way we attempt to confirm previous results that classify this ENSO episode asmixed behavior (i.e. EP and CP type of El Nio).
