This chapter links cloud, discussed in the previous chapter, with rainfall, considered in the next. Some correlation between cloud and rainfall is shown by Figure 9.1, with a weaker association in southern latitudes than northern. One reason is that areas between 15-30°S are frequently covered by stratus clouds which produce no rain. But there is a fair connection between cloud and rain in Australia (Figure 9.2, Note 9.A).
