Improving Heat-Related Health Outcomes System in an Urban Environment

An urban heat island (UHI) is an urban area or metropolitan area that is significantly warmer than its surrounding rural areas due to human activities. The temperature difference usually is larger at night than during the day, and is most apparent when winds are weak. UHI is most noticeable during the summer and winter. The main cause of the urban heat island effect is from the modification of land surfaces.[1][2] Waste heat generated by energy usage is a secondary contributor.[3] As a population center grows, it tends to expand its area and increase its average temperature. The less-used term heat island refers to any area, populated or not, which is consistently hotter than the surrounding area.[
HHWS is operated in U.S, Canada, Italy, China Shanghai currently. Our country is operating a trial version in seven urban areas currently (2010).
Currently, high temperature health warning system and existing heat wave newsflash are operated, which is to be expanded to local organizations with residents over 50 million people ( currently 20 cities operating). NWS forecasters are utilizing HHWS as summer heat wave forecast guidance with the national weather service and disaster prevention center.
Urban High Temperature Health Rate is related to the threat that citizens face as global warming and climate change increase as well as city population growth and rapid civilization. Heat wave from city high density is revealed to danger as temperature increases drastically in urban areas in accordance with the heat wave. Korea is vulnerable to high temperature as Korea is not in the tropical area, so to minimize casualties, the city developed city high temperature health rate in accordance with Korea main cities.
∎SSC, Spatial Synoptic Classification
Meteorological data is classified in 6 different types. The saved data is then researched by the team to verify timely, statistical, geographical data in order to find temperature, dew point temperature, sea surface pressure, etc.
∎EDA, Excess Deaths Algorithm
Produce EDA estimation model of heat wave air mass through SSC. Eliminate non-meteorological factors and analyze statistical interrelationship with standardized death data in order to find meteorologic cause for increasing casualties. National Statistical Office casualty cause statistics data from 1991 to 2007 was used for death data for EDA.
∎NWP, Numerical Weather Prediction
Each regional weather prediction data is used to predict casualties of the day after. Prediction data used in NWP is the current 48-hour town forecasts (ver. 3.0 : temperature, relative humidity, wind components, sky status)
∎HHWS, Heat Health Warning System
HHWS decides heat wave causing air mass through weather forecast data to process excess death prediction. Warning is sent in accordance with the predicted outcome. This information is automatically displayed on the web site.
