JCOMM Technical Report, 65. Stakeholders Workshop for JCOMM-CHy Coastal Inundation Forecasting Demonstration Project
The Stakeholders Workshop for JCOMM-CHy Coastal Inundation Forecasting Demonstration Project (CIFDP-BSW) was opened at 1000 hours in the conference room of the Bangladesh Meteorological Department (BMD), Dhaka, Bangladesh, at the kind invitation of BMD. Dr Arjumand Habib, Director of Bangladesh Meteorological Department (BMD) and the Permanent Representative of Bangladesh to WMO, welcomed all participants from national agencies and the Project Steering Group. In her opening remark, she emphasized the importance of this timely initiative of CIFDP to protect life and property in the coastal zon ...
JCOMM Technical Report, 64. Coastal inundation forecasting demonstration project - Implementation plan
Coastal disasters are a major threat to the people whose lives and livelihoods depend on safety and socio-economic development in low-lying, highly-populated coastal areas. They include storm surges and wind-induced waves associated with severe cyclones, and their combined effect with river flooding, leading to coastal inundation. Risk management for such coastal disasters represents a great challenge to scientists and policy makers in Meteorology, Hydrology, Oceanography, Emergency Management and Coastal Planning. In particular, recognizing this extreme vulnerability of coastal areas to storm ...
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.
JCOMM Technical Report, 58. Extreme value analysis: still water level
World Meteorological Organization (WMO) ; Intergovernmental Oceanographic Commission (IOC) - WMO, 2011In this report we begin by describing and discussing approaches based on extreme value theory that can be used to estimate return values of SWL in Chapter 2. We then present in Chapter 3 a worked example using a long-term time series of still water level measurements processed and quality-checked by the Dutch Ministry of Transport, Public Works and Water Management. They are the measurements of the gauge located at Hoek van Holland, The Netherlands (see Figure 3.1), available from 1887 onwards. In Chapter 4 we provide an inventory of software packages available to carry out extreme value analy ...
JCOMM Technical Report, 56. JCOMM Expert Team on Sea Ice (ETSI): 3rd Ice Analysts’ Workshop
Ice (ETSI), Dr. Vasily Smolyanitsky (Russian Federation), at 0900 hrs on Tuesday 18 June 2011 at the Danish Meteorological Institute, Copenhagen, Denmark. Dr. Smolyanitsky noted that the Ice Analysts’ Workshops are endorsed by both JCOMM and the International Ice Charting Working Group (IICWG) as being a valuable forum to share knowledge and coordinate ice information services throughout the world. Recognizing the increasing navigation that is taking place in the Arctic, five new METAREAs were created 3 years ago to ensure that Marine Safety Information (MSI) through the Global Global Maritime ...
JCOMM Technical Report, 59. Proceedings of the third International workshop on advances in the use of historical marine climate data
Marine surface observations—which represent a vital component of the Global Climate Observing System (GCOS)—are key to understanding global climate, including its variability on time scales ranging from sub-daily to weekly to centuries. Prior to 1970, ships were almost the only source of observations. In the modern era, sensors deployed on ships, moored and drifting buoys, aircraft, and Earth Observation (EO) satellites all provide surface measurements of many different variables. The Third International Workshop on Advances in the Use of Historical Marine Climate Data (MARCDAT-III) was hosted ...

JCOMM Technical Report, 04. The Voluntary Observing Ships Scheme, a Framework Document
World Meteorological Organization (WMO) ; Intergovernmental Oceanographic Commission (IOC) - WMO, 2010Ships of the World Meteorological Organization (WMO) Voluntary Observing Ship (VOS) scheme have always been an important component of the global observing system of the WMO, providing meteorological and oceanographic data essential to operational meteorology, maritime safety services, and a range of marine climatological applications. More recently, it has become clear that their observations can also be of critical importance to global climate studies.
JCOMM Technical Report, 23. SIGRID-3 :a vector archive format for sea ice charts
Intergovernmental Oceanographic Commission (IOC); World Meteorological Organization (WMO) ; International Ice Charting Working Group's Ad Hoc Format Team for the WMO Global Digital Sea Ice Data Bank Project - WMO, 2010 (revised edition; WMO/TD-No. 1214)This document describes the SIGRID-3 format so that it may be understood by a variety of users and implemented by chart-producing ice centers or services. SIGRID-3 evolved from earlier SIGRID formats and incorporates much of their content (see Appendix 1 for notes on earlier SIGRID formats and their application in SIGRID-3). For example, SIGRID variable identifiers such as “CT” for total concentration are used in SIGRID-3. While all SIGRID variable identifiers may be used in SIGRID-3, those that are commonly used are required, such as concentration, stage of development, and form. Users famili ...
