    La Niña to bring more rain and cool weather


    Swings that defy prediction

    About two La Niña and two El Niño events happen each decade, on average.

    However, the events are not cyclical — a La Niña does not necessarily follow an El Niño, nor vice-versa.

    Forecasts of a La Niña or El Niño's arrival, intensity and duration would be extremely valuable to many industries, especially agriculture.

    But despite cutting-edge modelling and more than 140 years of data, meteorologists cannot yet make accurate, long-term predictions.biggrin.png

    Dr Trewin said modern forecasts focus on sea temperature rather than air pressure (though the two are linked), and are improving.
