Abstract: Weather, climate and atmospheric environment are closely related to public health. Considering the prediction of weather, climate and atmospheric pollution in the future, the meteorological-health forecast can be made on the basis of scientific facts that illuminate impacts of meteorology and atmospheric environment on health. It was proved that meteorological-health forecasts have effects to reduce the occurrence of diseases, and improve the public health. In recent years, Scientists at Shanghai Meteorological Service have developed a heatwave and health monitoring warning system, and have carried out researches on meteorological health prediction and warning of bacterial food poisoning, heatstroke, common cold, childhood asthma and chronic obstructive pulmonary disease (COPD). The meteorological-health forecast products were developed based on determination of sensitive factors and qualification of exposure-response relationships. the Shanghai meteorological and environmental animal exposure system has been developed, and the toxicology experimental studies have been carried out to provide theoretical support for health forecasting.Shanghai Meteorological Service issued those meteorological-health forecast and warning messages to some hospitals, schools, and catering companies by various media, such as short message service (SMS), E-mail, the internet, WeChat, etc., cooperating with the health departments and education departments. Evaluation of meteorological-health forecasts were investigated by cross-sectional and intervention studies, the feedback of service objects revealed that those forecasts have positive effect on public health.
