After a brief mention of the distinct features of human biometeorology as compared with the other fields of biometeorology methods of approach are reviewed. The main aim of research is to establish a ranking order for the impact of the factors of the atmospheric environment within general biometeorology and within ecology as a whole. Both deductive and inductive methods reveal that all ranking is relative and dependent on the particular purpose served and the special limitations introduced through control of the ecosystem. The application of meteorology in the medical sciences requires a basic understanding of human biometeorology. It can only be fruitful if the various specialists define their purpose clearly so that meteorologists can arrange their recording scheme and data evaluation accordingly.
