TCP, 30. Regional Association IV – Hurricane Operational Plan for North America, Central America and the Caribbean (WMO-No. 1163), TCP-30
The regional activities under the WMO Tropical Cyclone Programme consist mainly of the programmes pursued by groups of countries acting in concert to improve their warning systems. In Region IV (North America, Central America and the Caribbean) there is a long history of collective action specifically designed to protect people and property from the severe tropical cyclones which are called hurricanes in the Region. A working group, known as the RA IV Hurricane Committee, was established by the seventh session of Regional Association IV (Mexico City, April May 1977) to promote such activities ...
Integrated Weather and Climate Services in Support of Net Zero Energy Transition (WMO-No. 1312)
The document is an update of the Global Framework for Climate Services (GFCS) “Energy Exemplar” and was compiled under the aegis of the WMO Study Group for Integrated Energy Services (SG-ENE ), part of the Commission for weather, climate, water and related environmental services and applications (SERCOM), with contributions from some of the leading experts in the field. The document provides the background and guidelines required to strengthen the development, and enable a widespread uptake, of integrated Weather & Climate Services (W&CSs) for the Energy sector needed to accelerate the transit ...
Guidance on Measuring, Modelling and Monitoring the Canopy Layer Urban Heat Island (CL‑UHI) (WMO-No. 1292)
The guidance provides an overview of and recommendations for measuring, modelling and monitoring the Canopy Layer urban heat island, which is based on temperature information at about 1.5 m above ground. Canopy Layer urban heat island information is one component of the integrated urban hydro-meteorological, climate and environmental services for citizens. These services may be provided directly by National Meteorological and Hydrometeorological Service (NMHS) operations, in cooperation with stakeholders or partners, or indirectly through stakeholders or partners in cities, public and private ...
Guidelines on the Definition and Characterization of Extreme Weather and Climate Events (WMO-No. 1310)
The guidance in this publication consists of generic definitions and methodologies for the characterization of extreme weather and climate events. This publication contribute to ensuring consistent exchange of information that underpins the WMO State of the Climate Reports, Climate Watches, climate change studies and other emerging applications.
Survey on the Status of Human Resources in National Meteorological and Hydrological Services: Staff, Competencies and Qualifications (WMO-No. 1305)
The WMO’s seventh survey on the status of human resources in National Meteorological and Hydrological Services (NMHSs), conducted from 2021 to 2022, reiterated the previous survey’s investigation of staffing patterns, and added inquiry concerning qualifications and competencies. The report’s introduction elucidates survey administration and major survey findings. The main body of the report presents detailed survey results in two parts: Staffing (numbers of staff by gender, professional category, attainment of university degree, age category, and staffing trends); and Capacity Development (num ...
حالة الموارد المائیة العالمیة في 2021 (مطبوع المنظمة رقم 1308)
As a first edition of the annual State of Global Water Resources, this report shows how maps and a graphical summary of streamflow and TWS in river basins worldwide could look in regular reports on global water resources. These maps are based on modelled data (and validated with observed data to the extent possible) and remotely sensed information from the NASA GRACE mission for TWS. Modelled data was used to achieve maximum geographical coverage. The 2021 report also includes chapters on major hydrological events in 2021 and a brief overview of cryosphere changes as they related to water reso ...
