WEATHER RELATED DISASTERS

• 1992-2001 CRED Statistics

• 90% of all natural disasters are weather related

• 622,000 Lost their lives-2 billion affected

• $446 billion in losses

NMHS’s REQUIRE REAL TIME HYDROMET DATA

• Climate models need GCOS Data

• Mesoscale models are increasing

• Distributed hydrologic models need high resolution data

• Tsunami models require pressure data

The Challenge: Sustaining our present HYDROMET networks

33% of EXISTING GUAN AND GCOS SURFACE STATIONS DO NOT REPORT

GCOS Surface Network (GSN)989 Stations

150 Stations

GCOS Upper Air Network (GUAN)

How to Build a network

• Have a Disaster– Hurricane MITCH

• Build a case to include Data Network as part of Bank LOAN– Russia, Poland,Romania

• Seek Donors – -Mekong streamgage network-Australia

Building your Case

• Analyze existing network– Develop Data network scenarious (ideal vs

basic)

– Examine forecasting and warning requirements for climatology, hydrology, meteorology and coastal surge/tsunami

– Conduct GAP analysis

Some Major DATA Players

Global Earth Observing System GEOSS)

GCOS Program

European Union

United States Agency for International Development

World Bank

United Nations (such as WMO WWW)

NOAA

Develop a Strategy

• To acquire funds to modernize Data Networks -Look at what opportunities exist!

• Develop a “marketing plan”– What are existing network limitations and resultant

negative impacts ?

– Describe users and Data needs (the Gap)

– Describe Data Network benefits vs costs for network scenarious

Develop USER Partnerships

• User Requirements for Data are your requirements

• Develop USER partnerships

• USERS assist NMHS in developing plan

• USERS lobby government to execute plan

Partnerships

New Weather Stations in Central America

SUMMARY

• NMHS’s cooperate to develop VISION (how?)• Develop Partnerships with USERS

– (energy. Emergency services,agriculture,media,transportation

• Costs vs Benefits calculated for network enhancement (how?)

• Make sure maintenance plans and funds included to assure sustainability

• Sell plan at every opportunity• Have patience
