Abstract
MOST maps hitherto constructed to show the mean annual distribution of rainfall are confined to the land areas and have no indication of rainfall over the oceans. Prof. W. Meinardus has published in Petermanns Mitteilungen (1934) a new rainfall map on a scale of 1: 100,000,000 which shows the distribution over the entire surface of the globe. On so small a scale it naturally does not differ materially so far as land areas are concerned from Supan's and other maps, although it shows effectively the low precipitation in north and south polar regions; but over the oceans, and in particular the Indian and Pacific Oceans, there is much of interest. These details have been taken chiefly from G. Schott's oceanic maps. The map is produced in tints of two colours showing six different grades of rainfall.
