“…It now appears to be as much triennial as biennial, and perhaps the time has come to give it still another name. Moreover, around 1962, an increase in the phase difference between the temperature oscillations and wind oscillations appeared at 10 mb while at lower levels it remained approximately constant (McInturff et al 1971, fig. 4).…”

“…An average temperature increase of 2" C everywhere in the lower stratosphere over the equator was due to the Mt. Agung eruption in 1963(McInturff et al, 1971. Recently opinions have been veering strongly around the hypothesis, which is based on both observational (Sedlacek et al, 1983) and theoretical studies (see for example , Pollack et al, 1976), that the amount of sulphurous gases released from eruptions has the ability to modify the climate.…”

Low‐latitude volcanic Eruptions and their effects on Sri Lankan rainfall during the north‐east monsoon

1987

Recent studies have pointed out the modification of climate by aerosols released in the stratosphere by strong volcanic eruptions. The rainfall at 15 meteorological stations in Sri Lanka and the low latitude (20" N to 20" S) volcanoes, having volcanic explosivity index (VEI) 4 or more, for a period of 112 years (1869-1980), are investigated to examine the effects of the eruptions on the rainfall activity over Sri Lanka during the north-east monsoon season (November and December). The present study has suggested deficient rainfall in 14 out of 15 Sri Lankan stations during both the first and the first two successive north-east monsoon seasons, which followed 53 to 80 per cent of volcanic eruption years. Also 53 to 100 per cent of the stations received deficient rainfall during both the first and the first two successive north-east monsoon seasons following 12 out of 20 volcanic eruption years. Occurrence of deficient rainfall to the north of the inter tropical convergence zone (ITCZ) over Sri Lanka after the eruptions of the low-latitude volcanoes could be attributed to the southward shift of the ITCZ due to depletion of the solar radiation caused by the aerosols released in the stratosphere by the strong volcanic eruptions.

S U M M YThe existence. statistical significance, and possible causes of stratospheric temperature anomalies observed at the 100 mb level in the Australasian ngim in 1963 and 1% are discussed with r e f e m to the so-called quasi-biennial oscillation. volcanic dust, and the general circulation. This discussion is facilitated by the use of the observed correlation between stratospheric temperatures and the mean latitude of the surface high pressure belt, in order to increase the sensitivity of a statistical test for anomalous temperatures.
