Guide to Wave Analysis and Forecasting
This publication is the outcome of the revision, expansion, and up-dating of the 1998 Guide to Wave Analysis and Forecasting. It is designed to enhance the provision of up-to-date information and guidance material on all aspects of the ocean-related activities of National Meteorological Services.
This 2018 (3rd edition) represents the latest updates, taking into account the dramatic improvements in wave modelling and observational capability over the last two decades. It also contains a web-based Dynamic part, describing operational wave models, also available on the WMO website ...

The comparison of SWH from ocean wave spectra and nadir beam of SWIM
The surface wave investigation and monitoring (SWIM) will be one of the two payload instruments carried by China France Oceanography Satellite (CFOSAT) with a planned launch date in mid-2018. SWIM has six beams rotating around the vertical axis at incidence angles 0,2,4,6,8,10 degree. With nadir-beam, the SWH and wind speed can be detected as the same principle as an altimeter. At the same time, the ocean wave spectrum beams can also Catch the significant wave height (SWH). To find which SWH is more stable and accurate, first, the thesis presents an overview of SWH detection from a satellite. ...
Extreme High Swell Events on the Moroccan Atlantic Coast
High swell events can develop far from the coast under cyclonic conditions, and take several days to travel to land. If early warnings are not issued, they can take an area by surprise and have a devastating impact. This lesson aims to improve the ability of marine forecasters to forecast extreme marine events related to high swells. It does so by providing background information on winds and waves, and presenting a process for monitoring and forecasting high swell events using a variety of data. These include ASCAT scatterometer wind data and the ECMWF Extreme Forecast Index (EFI) product, wh ...

Changing wave heights projected as the atmosphere warms: In Australasian Science
2013Climate scientists studying the impact of changing wave behaviour on the world's coastlines are reporting a likely decrease in average wave heights across 25 per cent of the global ocean.

JCOMM Technical Report, 62. Proceedings: 7th TCP-JCOMM Workshop on Storm Surge and Wave Forecasting (SSW-7)
The Seventh TCP/JCOMM Workshop on Storm Surge and Wave Forecasting was held at Macao Meteorological and Geophysical Bureau (SMG), Macao, China, from 10 to 14 October 2011.
This series of workshop is co-organized by the Tropical Cyclone Programme (TCP) of the World Meteorological Organization (WMO) and the Technical Commission for Oceanography and Marine Meteorology (JCOMM) that is jointly supported by WMO and the Intergovernmental Oceanographic Commission (IOC), with a view to enhancing capacities of National Meteorological and Hydrological Services (NMHSs) for reduction of mari ...
Arctic Meteorology and Oceanography
Diminishing sea ice has opened the Arctic to navigation and operations like never before. Forecasters are increasingly predicting weather in support of those operations. This module is intended to provide forecasters with a brief introduction to the Arctic, including its geography, climatology, and the forecast problems they are likely to encounter. The module follows a U.S. Coast Guard Cutter on a voyage from Dutch Harbor, in the Aleutian Islands, to Barrow, on the north coast of Alaska. Various topics are addressed along the way in a series of short, stand-alone lessons.

JCOMM Technical Report, 68. 8th JCOMM-TCP Workshop on Storm Surge and Wave Forecasting (SSW-8): proceedings
The Eighth JCOMM-TCP Workshop on Storm Surge and Wave Forecasting (SSW-8) was held at the Institute for Meteorological Training and Research (IMTR), Nairobi, Kenya, from 19 to 23 November 2012.
This series of workshop is co-organized by the Joint WMO-IOC Technical Commission for Oceanography and Marine Meteorology (JCOMM) and the WMO Tropical Cyclone Programme (TCP), with a view to enhancing capacities of the National Hydrological and Meteorological Services (NMHSs) in providing necessary forecasting and warning services against natural marine hazards that complement b ...
Flow, waves and water exchange in the Suur Strait, Gulf of Riga, in 2008
Wind, flow and wave measurements were performed in November-December in 2008 in the relatively narrow and shallow Suur Strait connecting the waters of the Väinameri and the Gulf of Riga. During the measurement period wind conditions were extremely variable, including a severe storm on 23 November. The flow speed along the strait varied between ±0.2 m s-1, except for the 0.4 m s-1 that occurred after the storm as a result of the sea level gradient. The mean and maximum significant wave heights were 0.53 m and 1.6 m respectively. Because of their longer fetch, southerly winds generated higher wa ...
JCOMM Technical Report, 57. Extreme value analysis: wave data
World Meteorological Organization (WMO) ; Intergovernmental Oceanographic Commission (IOC) - WMO, 2011In this report we begin by describing and discussing approaches that can be used to estimate such return values in Chapter 2. Approaches based on extreme value theory as well as ad hoc methods are considered. We then present in Chapter 3 some worked examples using two time series of significant wave height measurements, one in deep and the other in shallow waters. In Chapter 4 we provide an inventory of software packages available to carry out extreme value analyses. We finish in Chapter 5 with some guidelines / recommendations.
Community Tsunami Preparedness, 2nd Edition
This lesson is designed to help emergency managers prepare their communities for tsunamis. Topics include basic tsunami science, hazards produced by tsunamis, the tsunami warning system, the importance of public education activities, and how to craft good emergency messages and develop tsunami response plans. The lesson also contains links to extensive Reference and Resources sections.
JCOMM Technical Report, 55. WCRP-JCOMM Workshop on Coordinated Global Wave Climate Projections (COWCLIP)
World Meteorological Organization (WMO) ; Wang Xiaolan L.; Weisse Ralf; et al. - WMO, 2011 (WMO/TD-No. 1518)The Coordinated Ocean Wave Climate Projections (COWCLIP) workshop was held on April 11-13, 2011, at the World Meteorological Organization (WMO) in Geneva, Switzerland, with the support of the World Climate Research Programme and the Joint Technical Commission for Oceanography and Marine Meteorology of WMO and Intergovernmental Oceanographic Commission (IOC) of UNESCO. The workshop aimed to bring together international researchers with interest in wind wave climate variability and change, to discuss the potential path forward for a collaborative working group to address challenges in this field ...
