The Earth’s Problem Climates used the ideas of dynamic and synoptic climatology to attempt to explain why certain areas of the world failed to conform to the classical paradigm of regional climatology. Anomalous areas of temperature and precipitation were cataloged and explained in terms of local variations in the landscape or circulation. Over four printings, the book was never thoroughly revised and as such failed to keep up to date to changes in the atmospheric sciences. Despite this failing, The Earth’s Problem Climates is an important bridge between classical regional climatology texts and the process focused texts of today.
