Flood Management Tool Series, Technical Document, 09. Flood Management in a Changing Climate
This tool is an initiator and starting point on how flood management can be an autonomous part of an adaptation strategy to climate change. Flood managers have vast experience in managing floods under current climate variability. Floods are among the most widely cited expected impacts of global warming, either with an increased frequency or with increased magnitude in particular regions. As such climate change poses an additional challenge that needs a conscious strategic reorientation of flood management practices towards applying risk management techniques and involving a far broader set of ...
WCDMP, 70. Guidelines for Plant Phenological Observations
The technical document on the guidelines for plant phenological observations raises the benefits of these types of observations in monitoring the impact of the changing climate on an important biosphere element of the climate system which is vegetation. The content of the document was elaborated by experts in climatology and biometeorology in a multidisciplinary team work approach. The guidelines included in the document are based on scientifically recognized principles and good practices undertaken by several institutions having long experience in carrying out plant phonological observations ...
SP, 05. The potential role of WMO in Space Weather : a report on the potential scope, cost and benefit of a wmo activity in support of International coordination of space weather services, prepared for the sixtieth executive council
The present report addresses the possible scope, cost and benefit of initiating a WMO activity in the area of Space Weather. The expression Space Weather is used to designate processes occurring on the Sun, in the magnetosphere, ionosphere and thermosphere, which have the potential to affect the near-Earth environment. These processes occurring mainly outside of the atmosphere are not meteorological phenomena, and thus haven’t so far been considered within the mandate of WMO. However, because of their importance and possible synergy with activities under WMO’s responsibility, the issue o ...

Climate Variability and Predictability (CLIVAR), 1496. Challenges and opportunities in research on climate, weather, water and environment : research aspects of an Enhanced Climate; Weather, Water and Environmental Prediction Framework
Advances in the geophysical sciences and computing have led to a number of opportunities for WMO. First, the distinction across timescales from weather to climate prediction is becoming more blurred; second the incorporation of chemical, hydrological and biological processes into weather and climate models will allow a much broader range of environmental parameters to be forecast, including air quality, flooding, sand and dust storms, changes in vegetation etc. Third, many of the applications and impacts of weather and climate share a common underlying scientific basis.
Integrated Flood Management : concept paper
World Meteorological Organization (WMO) ; Associated Programme on Flood Management (APFM); Global Water Partnership (GWP) - WMO, 2009 (WMO-No. 1047)Integrated Water Resources Management (IWRM), as defined by the Global Water Partnership, is “a process which promotes the coordinated management and development of water, land and related resources, in order to maximize the resultant economic and social welfare in an equitable manner without compromising the sustainability of vital ecosystems”. This approach recognizes that a single intervention has implications for the system as a whole, and that the integration of development and flood
management can yield multiple benefits from a single intervention.

WCDMP, 76. Proceedings of the sixth seminar for homogenization and quality control in climatological databases
The aim of the homogenization procedures is to detect the inhomogeneities and to correct the series. In practice there are absolute and relative methods applied for this purpose. However the application of absolute methods is very problematic and hazardous since the separation of climate change signal and the inhomogeneity signal is essentially impossible. Relative methods can be applied if there are more station series given, which can be compared mutually. The methodology of comparison is related to the following questions: reference series creation, difference series constitution, multiple ...
