World Meteorological Organization and World Health Organization. (2015). Heatwaves and Health: Guidance on Warning-System Development.

These guidelines provide an overview of general heat–health problem and describe how an understanding of the biometeorology, epidemiology, public-health and risk-communication aspects of heat as a hazard can be used to inform the development of a heat-health warning system (HHWS) as part of a wider heat-health action plan (HHAP).
