  It is shown that the north-south teleconnections in the northern hemisphere:
North Atlantic (NAO), East Pacific (EPO), Western Pacific (WPO) dipole
oscillations and Pacific/North American quadrupole pattern (PNA), are dominated
by the Hamiltonian distributed chaos on the daily to intraseasonal time scales.
Differences of the chaotic properties of the dipole and quadrupole oscillations
as well as their relation to the surface air temperature have been briefly
discussed. A chaotic spectral affinity of the PNA quadrupole pattern to the
Arctic Oscillation and the Greenland blocking phenomenon have been considered
in this context.
