Outline

• Why Climate Monitoring is important• WMO’s Climate Monitoring activities• Strategies for developing and improving

Climate Monitoring capabilities• Discussion

3Climate Monitoring Technical Conference on Changing Climate and Demands for Climate Services, 16 February 2010, Antalya, Turkey 3

Consider a city running low on drinking water during a drought

• If you were in charge of the city’s long-term water planning, what would you do?

4Climate Monitoring Technical Conference on Changing Climate and Demands for Climate Services, 16 February 2010, Antalya, Turkey 4

The answer depends on climatic conditions

• Is this is a once in 200 years drought or a once in 20 years drought?

• Do long-term data (and model projections) indicate that droughts of this magnitude are tending to become more frequent or less frequent?

• How could you possibly make the right decision without climate monitoring information?

Climate Variability and Change • Impacts numerous societal, economic and

environmental aspects– Safety, health, food security, tourism, energy, etc.

• Therefore, coping and adapting to these changes requires understanding their causes, magnitudes and extent, and to predict their impacts.

Climate Monitoring • Provides information needed for effective

planning– As well as for operations to respond to extreme

events

WMO Climate Monitoring Activities

8Climate Monitoring Technical Conference on Changing Climate and Demands for Climate Services, 16 February 2010, Antalya, Turkey 8

WMO AnnualState of the Global Climate

• Since 1993• In collaboration with the

WMO Commission for Climatology

• Authoritative yet simple– E.g., 13 heavily illustrated

pages

9Climate Monitoring Technical Conference on Changing Climate and Demands for Climate Services, 16 February 2010, Antalya, Turkey 9

WMO also collaborates on the larger Bulletin of the

American Meteorological Society’s Annual

State of the Climate

• Identifying potential authors

• Encouraging interactions

10Climate Monitoring Technical Conference on Changing Climate and Demands for Climate Services, 16 February 2010, Antalya, Turkey 10

CCl Expert Team on Climate Monitoring

• Including the use of Satellite and marine data and products

• Focused on what a small international team of experts could provide any NMHS trying to improve their climate monitoring

11Climate Monitoring Technical Conference on Changing Climate and Demands for Climate Services, 16 February 2010, Antalya, Turkey 11

Expert Team Actions• Started out by providing information on Climate

Monitoring to WMO Member States.• Web site with climate monitoring relevant links• A pamphlet to provide outreach to the community• Coordinating translation of the BAMS State of the Climate into

Spanish, Chinese, Arabic, French and Russian so more people could read it

• Publicizing important information• Such as Guidelines for plant phonological observations

• Writing an article for the WMO Bulletin

WMO Bulletin April 2008

12Climate Monitoring Technical Conference on Changing Climate and Demands for Climate Services, 16 February 2010, Antalya, Turkey 12

By the time the 4 years ended

• Focus evolved towards building and formalizing interactions– Enhancing collaboration between major global

climate monitoring centers– Capacity building collaboration between a satellite

agency and an individual NMHS

• Lesson learned:– Interactions between scientists is the key first step

towards improving climate monitoring

Strategy for Improving and Developing Climate Monitoring

14Climate Monitoring Technical Conference on Changing Climate and Demands for Climate Services, 16 February 2010, Antalya, Turkey 14

The Key is Participation

• Until one attempts to monitor the climate it is difficult to appreciate the many different things that need to come together in Climate Monitoring

15Climate Monitoring Technical Conference on Changing Climate and Demands for Climate Services, 16 February 2010, Antalya, Turkey 15

The Importance of Historical Data

• It is the long-term data that allow one to put current conditions into perspective– Rescue and digitize old records

16Climate Monitoring Technical Conference on Changing Climate and Demands for Climate Services, 16 February 2010, Antalya, Turkey 16

The Importance of Homogeneity

• Artificial discontinuities in the data can paint an erroneous climate picture

• Rize, Turkey• Discontinuity

verified by metadata indicating that station relocated in 1995

17Climate Monitoring Technical Conference on Changing Climate and Demands for Climate Services, 16 February 2010, Antalya, Turkey 17

The Importance of Cross-Border Verification

• Verification by seeing how local conditions fit into global and regional patterns

• Highlights the importance of internationally sharing data and information

18Climate Monitoring Technical Conference on Changing Climate and Demands for Climate Services, 16 February 2010, Antalya, Turkey 18

The Importance of Daily Data

• Can’t globally monitoring daily temperature extremes– Yet extremes are more societal relevant than monthly

average• Heat wave related to increased mortality• Cold extremes related to agricultural damages

• The same is true for precipitation extremes– Long-term droughts can be monitored– But heavy flood producing precipitation events often

can not be monitored globally and put into accurate historical perspective

19Climate Monitoring Technical Conference on Changing Climate and Demands for Climate Services, 16 February 2010, Antalya, Turkey 19

The Importance of Information, not just Data

• Even where data are not shared, other information can be• Indices of extremes coordinated by the joint

CCl/CLIVAR/JCOMM Expert Team on Climate Change Detection and Indices

• A challenge to address in near real-time• Reporting climate conditions in the annual State

of the Climate report is enhancing cross-border exchange of information and collaboration on climate monitoring.

• RCCs could play an important role

20Climate Monitoring Technical Conference on Changing Climate and Demands for Climate Services, 16 February 2010, Antalya, Turkey 20

Hands-on Workshops are an Effective Strategy for Development

• Not just listening and talking but doing also– Photos from Caribbean Climate Extremes workshop

21Climate Monitoring Technical Conference on Changing Climate and Demands for Climate Services, 16 February 2010, Antalya, Turkey 21

Summary

• Real-time global, regional and local climate monitoring poses tremendous challenges• A complex and multifaceted problem

• Only by attempting climate monitoring can a full appreciation of all the processes come together• Regional workshops can jump start that process

• Society needs this information to help guide adaptation to climate change
