Aim of talk
WMO OMM
To provide some examples of WMO co-ordinated activities,
which aim at sustained
global and regional climate information
generation and provision
in support of national climate services

WMO OMM
Global Framework for Climate Services
WCC3 decided to
establish a Global
Framework for Climate
Services (GFCS) to
strengthen the
production, availability,
delivery and application
of science-based climate
prediction and services.

WMO OMM
Global Framework for Climate Services
The Climate Services Information System (CSIS) is the component of the Framework that is
designed to routinely generate climate information
which users need for the decisions they have to make.
Relevant WMO current strengths as of now include:
-GDPFS including 12 GPCs and 2 Lead Centers as well as 2 RCCs
-Regional institutions, such as DMCs, ACMAD, ICPAC, CIIFEN
-Standards and best practices for operations (-> CCl, CBS)
-WMO El Niño/ La Niña Update, etc.
Examples of relevant WMO contributions to GFCS implementation include:
-Promote national mechanisms to strengthen capacities of members to provide climate services
-Extension of GPC and RCC networks and RCOFs to cover all climatic regions
-Expansion of RCC operations to cover regional climate change scenarios
-Development of additional global climate updates (-> GSCU), etc.

WMO Global Producing Centres
WMO OMM
Function of WMO GPCs: Provision of global-scale long-range (seasonal) prediction
information to Regional Climate Centres, Regional Climate Outlook Forums and National
Meteorological and Hydrological Services
Note: Other centres produce equivalent products (e.g. IRI, APCC)
Variables:
2m temp, precip and SST
Format:
probabilities for tercile categories
Temporal resolution:
1 month or longer (seasons)
Spatial resolution:
2.5°x2.5°
Coverage:
global
Lead time:
between 0 and 4 months;
Issue frequency: monthly or at least quarterly
Many GPCs provide additional variables (e.g. pmsl, T 850hPa); products (e.g.
ensemble mean anomaly); and longer range products.

WMO Regional Climate Centres
WMO OMM
• RCCs are Centres of Excellence, which
perform mandatory operational regionalscale climate functions in the domains of
long-range forecasting, climate
monitoring, data services and training
Mandatory product list (examples):
Assessment of GPC products
Regional/sub-regional seasonal outlooks
Consensus outlook statements
Verification datasets
• Highly recommended functions comprise
the domains of climate projections, coordination, capacity building and R&D
• RCCs are complementary to and
supportive of NMHSs, which deliver all
warnings and national-scale products
Climate diagnostics bulletins
Reference climatologies
Implementation of climate watches
Regional climate datasets
Training, feedback mechanisms,
information portals

WMO Climate Watch Systems
WMO OMM
WMO Climate Watch systems…
… enable delivery of national climate advisories
on occurring and expected climate anomalies to users as a climate service
… are part of the mandatory RCC functions
and will receive guidance information from
regional entities and mechanisms, such as
RCCs and RCOFs,
… might be fed by global guidance products, such as
WMO’s El Niño/La Niña Update and the upcoming
GSCU

Regional Climate Outlook Forums
WMO OMM
RCOFs bring together national, regional and international climate experts,
on a regular basis, to produce regional climate outlooks based on
input from global and regional producers of climate information as well as
from NMHSs of the region concerned.
The RCOF mechanism:
---> addresses regions of common climate characteristics
---> ensures consistency in access to, and interpretation of, climate
information
---> facilitates close user interaction to jointly assess the likely implications
of the outlooks
---> provides training on long-range forecasting, communication etc.

WMO El Niño/La Niña Updates and GSCU
WMO OMM
WMO has been issuing consensus based
El Niño/La Niña Updates on a quasi-regular
basis over the past more than a decade, providing
useful information on these events of significant
importance to regional climate impacts.
From 12-14 Oct 2010, an Expert Meeting
on Scoping Global Seasonal Climate
Updates (GSCU) took place at WMO
Headquarters, expanding the idea of El
Niño/La Niña Updates to a quarterly
publication on the observed status and
potential evolution of the global climate
(ENSO, SST, TT, RR, significant events).

Annual WMO Statement
WMO OMM
Each year WMO produces its Statement on the Status of
the Global Climate
The activity consists of a press release mid December
and the publication of a 12-page brochure in March of
the following year
The brochure provides information mainly about global
temperature, regional temperature and precipitation
patterns, hazards, droughts and floods, tropical cyclones,
ENSO, Arctic Sea Ice. A feature article informs on a
subject of interest attached to the content of the brochure.
16
Global Climate Datasets
WMO OMM
Amongst a huge variety of different existing global data sets and relevant
initiatives, including Data Rescue, are two ‘famous’ examples of data sets
compiled in international collaboration under WMO co-ordination:
World Weather Records (WWR) have been published since 1927, and include
monthly mean values of pressure, temperature and precipitation, as well as
station metadata; data are collected for periods of 10 years (e.g. 1991-2000)
Climatological Normals (CLINO): 30-year means for standard reference periods
(current period: 1961-1990) incl. relevant statistics (percentiles, number of days,
frequencies, etc.) for a variety of parameters from over 4000 stations worldwide
17
Climate Projections
WMO OMM
WCRP Coupled Model Intercomparison Project (CMIP)
and
WCRP Co-ordinated Regional Climate Downscaling
Experiment (CORDEX)
provide frameworks for climate
change scenario development on global and regional level
including data access.
