ABSTRACT
Although this book is concerned with the weather and climates which are a vital part of the human environment at the ground, it is necessary to pay some attention to the stratosphere. This is partly because of the likelihood of (a) some interaction between the independently generated circulations of the stratosphere and troposphere, and (b) variable damping effects upon the circulation in the lower atmosphere (troposphere) due to some (probably slight) variation of long-term mean tropopause height associated with variations in the direct heating of the stratosphere. But also there is reason to suppose that some grand-scale effects of the circulation and patterns of vertical motion in the troposphere may reveal themselves in simpler shape in the lowest layers of the stratosphere that are affected by that vertical motion.
