2. How Does the Global Operational Network of WMO Operate? NMHSs deliver data and early warning services 3 World Meteorological Centres 40 Regional Specialized Centers NMHSs of 187 countries contribute to Global Observing System every day Global Telecommunication System- 32 Regional Tele-communication Hubs

3. WMO Global Telecommunication System (GTS), linking National Meteorological Services of 187 countries and territories, has been established as the backbone for exchange of natural hazards related information and warnings, including tsunami (e.g.Pacific, Indian Ocean).
