Although all weather is driven by large scale weather patterns, the characteristics of urban settings—such as buildings of varying heights and large areas of paved streets and parking lots—can generate a unique urban weather environment. Given that three out of five people worldwide are expected to live in an urban environment by 2030, accurately forecasting urban weather is becoming increasingly important to protect these densely-populated areas from the impacts of adverse weather events. Currently, the diverse needs of users of meteorological data in the urban setting, such as emergency managers and urban planners, are not being well met by the scientific community, mainly because of limited communication between the two communities. A clear mechanism to help the urban meteorological community better identify user groups, reach out to them, and maintain an ongoing dialogue would lead to better urban weather forecasting and planning in the future.
