Abstract
After the eruptions of the volcanoes Sierra Negra (1979, Galapagos), Mount St. Helens (1980, USA), and Alaid (1981, USSR) had initiated a period of enhanced stratospheric aerosol loading, two eruptions in 1982 further increased this perturbation. The origin of the first of these two events has still not been determined but was probably in the tropics early in January 1982. The second event in 1982 was a series of eruptions of the Mexican volcano El Chichon, from March 28 through April 4. There is some evidence that the El Chichon stratospheric cloud was confined south of 30 degrees N for at least four months after the eruption. But mid-latitude observations of intense dawn and dusk coloration indicated that by the summer of 1982 part of the El Chichon cloud had moved northward to produce scattering at great heights. (IFU)
