摘　　要：Large amounts of gases (e. g. sulphur dioxide and hydrogen sulphide) and silicate dust particles are injected into the lower stratosphere by a violent volcanic eruption and dispersed almost on the global scale by the upper wind. The enormous increase of stratospheric aerosol particulates concentration centred at an altitude of approximately 20 km after a violent volcanic explosion may last 3—4 years. The dense stratospheric aerosol layer is usually called volcanic clouds. Some researches show that stratospheric volcanic clouds result in a decrease of average temperature at the earth’s surface.
