    Notes: Abstract We studied the occurrence of ENSO (El Niño-Southern Oscillation) events in relation to solar activity conditions and we found that the events are distributed in two populations, one that could be associated with low latitude coronal holes which occur along the ascending phase of the cycle and the other one which could be related to polar holes present at the end of the descending phase. As highly anomalous solar activity, in terms of flares and coronal holes, occurred in March of this year, we propose that an ENSO event is likely to occur by the end of the year.

    Sound and thermal waves propagation in a hydrogen plasma heated by an external radiation field (1990)

    Notes: Abstract The thermal equilibrium of a hydrogen plasma heated and ionized by an external radiation field, diluted by a factorW * and defined by an effective temperatureT *, is studied. In addition, the problem of propagation of acoustic and thermal waves in the above plasma model is also analysed. It is found that an external radiation field has stabilizing effects against wave amplification. From the dispersion relation obtained, the phase velocity $$\tilde v$$ for sound and thermal waves and their respective scale-length of damping (or anti-damping) $$\tilde \omega $$ is calculated as a function of the frequency $$\tilde l$$ for representative values of the plasma temperature $$\tilde T$$ and the external radiation fieldT *.
