Climate Risk Early Warning Systems Annual Report 2022
The 2022 Annual Report of the Climate Risk Early Warning Systems (CREWS) Initiative highlights that an estimated 111 million people are better protected against climate-related hazards thanks to the early warning systems that it has put into place in 2022. An additional 282 million people in least Developed Countries and Small Island Developing States should be covered by better weather and climate services in the next few years, according to the Report,” which maps how the initiative helps saves lives, livelihoods and assets in the world’s most vulnerable countries by building resilience against hazards like drought, floods, sand and dust storms and coastal flooding.

Guidelines on High-resolution Numerical Weather Prediction (WMO-No. 1311)
The WMO Unified Policy for the International Exchange of Earth System Data (Resolution 1 (Cg-Ext(2021))) recognizes that all WMO Members require access to high-quality Numerical Weather Prediction (NWP) data. The newly released Guidelines on High-resolution Numerical Weather Prediction (WMO-No. 1311) aim to support all National Meteorological and Hydrological Services (NMHSs), regardless of resourcing levels, in gaining access to high-resolution NWP data, and to enable them to then use these to improve forecast and warning services.
The guidelines, based on well-established practices, propose a framework for NMHSs to access each of six increasingly refined levels of NWP, starting with the use of NWP data from World Meteorological Centres. The superior quality data and products generated by the global NWP models provide the best basis for the provision of forecasts and warnings services. These high-resolution global NWP are a core resource for achieving the United Nations Secretary-General’s target to ensure early warning services for weather hazards for all. Where effective basic services are already in place and additional resources are available, the higher levels of the framework may provide access to more refined high-resolution detail, including from advanced regional NWP systems, which may further enhance the services provided by an NMHS.
This publication will be very useful to the NMHSs in developing strategies for accessing and using high-resolution NWP as well as for implementing operational NWP services. Seamless data access remains a priority area as the Global Data-processing and Forecasting System (GDPFS) evolves into the WMO Integrated Processing and Prediction System (WIPPS).
