The Seventeenth World Meteorological Congress in 2015 appointed Petteri Taalas as Secretary-General of the World Meteorological Organization (WMO) and gave him a strong mandate to reform the WMO governance structure. Climate change, an increasing number of disasters, population growth, urbanization, uneven development of countries and new technologies were the main drivers for the reform.

Coastal inundation occurs along vulnerable coastlines. The combination of storm surges – typically from tropical cyclones or extratropical storms – and waves, with riverine flooding at various tidal states regularly leads to major loss of life. At least 2.6 million people are estimated to have drowned due to coastal inundation caused by storm surges over the last 200 years (Dilley et al., 2005).

The WMO Community Platform launched at the Eighteenth World Meteorological Congress (Cg-18) in June. Its first module, the Experts Database (contacts.wmo.int), replaces the static Pub5 with an interactive self-service system that allows Members to review and update information about experts and organizations. In September, the Platform’s new revamped extranet − organized by activity area and integrating events and document sharing for working in teams − went live.

The adoption of Resolution 40, WMO Policy and Practice for the Exchange of Meteorological and Related Data and Products including Guidelines on Relationships in Commercial Meteorological Activities, by the Twelfth World Meteorological Congress in 1995 (Bautista Pérez, 1996) remains a watershed event in the history of WMO. In some respects, it marked the end of what has been called the golden age of international cooperation in meteorology.

An international expert task team on nowcasting has developed the WMO Guidelines for Nowcasting Techniques (WMO, 2017) to initiate a process for an enhanced integrated and seamless WMO Data-processing and Forecasting System (DPFS). Their purpose is to help National Meteorological and Hydrological Services (NMHSs) by providing them with information and knowledge on how to implement a nowcasting system with the resources available to them and an understanding of the current state of science and technology.

Operational weather forecasting has reached a turning point. It is possible that it could be reshaped by the “Triple-In” properties of “indispensability”, “inexactitude” and “incompleteness” of numerical models. The indispensability of numerical models is a salient feature of current operational weather forecasting. But inexactitude is rooted in almost all numerical schemes, and incompleteness of numerical models will always exist due to the extreme complexity of the Earth system.

Over the past decades, meteorological and hydrological services have seen a growing participation of the private sector in weather and climate services (WCS) 1 as a result of many interacting factors. Technical developments in observation technology, such as remote-sensing, and reductions in the unit cost of information and measurement equipment, have made observation capacity more affordable and accurate.

The effects of climate change are becoming more evident. Governments are addressing the challenge of climate change through international accords such as the Paris Agreement in 2015. To evaluate progress towards climate targets, governments have adopted a process of national greenhouse gas (GHG) emissions reporting following agreed protocols. These protocols were established by the Intergovernmental Panel on Climate Change (IPCC) and described in the 2006 IPCC Guidelines for National Greenhouse Gas Inventories (IPCC, 2006).

Air pollution is the greatest environmental risk to human health. Outdoor air pollution leads to more than 4 million deaths each year, mostly in developing countries (World Health Organization (WHO), 2019). While air quality has improved in many countries in response to effective emission control strategies, other parts of the world continue to experience severe or deteriorating air quality.
