WMO Guidelines on Multi-hazard Impact-based Forecast and Warning Services (WMO-No. 1150), Part II: Putting Multi-Hazard IBFWS into Practice
This publication, 1150 Part II follows WMO-No. 1150, Part I which was published in 2015. In the intervening years, as many NMHSs and their partner agencies developed impact-based forecast and warning services (IBFWS), understanding, experience and knowledge in this area has developed and grown significantly. The material presented in this “1150 Part II” seeks to distil and summarise that knowledge and to provide examples of good practices in IBFWS, illustrating and augmenting the insights contained in the original guidelines.

The focus of this document is on observations at surface meteorological observing stations. However, many of the principles will also be valid for other forms of observations, including upper-air observations and datasets based on mobile or remotely sensed platforms (for example, satellites, radar or drifting buoys). In particular, as many key remotely sensed datasets begin in the 1970s, it is recommended that, where feasible, the current climatological standard normal period (1981–2010 at the time of writing) be used for these datasets to allow comparison among different data forms on a consi ...
