“…One of the most important sources of variability in the stratosphere may be the injection of aerosols by volcanic eruptions. Considerable heating that occurred in the lower stratosphere after the volcanic eruptions of Agung (1963), E1 Chich6n (1982), and Pinatubo (1991) has been observed [Newell, 1970;Labitzke and McCormick, 1992;Fujita, 1985;Kawamata et al, 1992]. On the other hand, van Loon and Labitzke [1987] and Labitzke and van Loon [1989] (hereafter referred to as vL and Lv, respectively) noted the strengthening of the polar vortex after the eruptions.…”

It has been suggested that the zonal‐mean stratospheric zonal‐wind anomalies can propagate downward into the troposphere, producing considerable changes. On the other hand, volcanic aerosols are thought to produce a stronger polar vortex in the winter stratosphere. If these suggestions are correct, the influence of volcanic eruptions can be expected to produce changes in the northern hemisphere winter troposphere through stratospheric process. In the present study, this idea is examined by analyzing changes in the January circulation after three recent volcanic eruptions. Regional features of observed changes in tropospheric temperatures due to volcanic eruptions can be explained by the changes in the propagation of stationary waves associated with dipole‐type anomalies in the zonal‐mean zonal winds, which are similar to those observed in a previous work on the influence of polar night jet.

“…It is well known that aerosols injected into the low stratosphere by major volcanic eruptions result in a warming of this region of the atmosphere [Newell, 1970;McInturff et al, 1971;Pittock, 1974;Labitzke et al, 1983;Parker and Branscombe, 1983;Angell and Korshover, 1983b;Fujita, 1985;Labitzke and McCormick, 1992;Spencer and Christy, 1992] Angell and Korshover [1983a]. The analysis is extended into the middle stratosphere of the tropics using a 10-station radiosonde network [Angell and Korshover, 1983b] as well as a 6-station rocketsonde network [Angell, 1991].…”

Based on a 63-station radiosonde network and using 9-season-average temperatures to minimize the influence of the quasi-biennial oscillation, the 1ow-stratospheric (16-20 km) warming following Agung and El Chichon was greatest in the equatorial zone and least in polar zones. The warming was not symmetric with respect to the equator, however, with greater warming south than north of the equator. The warming following El Chichon was slightly greater than following Agung in all climatic zones except the south polar zone. Results for Pinatubo are preliminary because of the recency of the eruption, but in north extratropics and tropics the warming following this eruption is indicated to be comparable to the warming following Agung and El Chichon. However, in south temperate and polar zones the warming is considerably greater following Pinatubo, perhaps reflecting a contribution from the eruption of Cerro Hudson in Chile. Globally, therefore, the low-stratospheric warming following Pinatubo is greater than following Agung or El Chichon. Based on a 10-station tropical radiosonde network with data to greater heights, the warming following El Chichon exceeded the warming following Agung to a height of at least 31 km, the difference in warming increasing with height. The warming following Pinatubo is similar to that following Agung to a height of 24 km, but thereafter is indicated to become less, an unexpected result to be reexamined as more data become available. 5, 858-866, 1992.
