Hydrometeorological Disasters

Hydro-meteorological disasters are natural phenomena that arise from the interaction between the water cycle and meteorological processes between the atmosphere and the Earth’s surface. These events significantly disrupt societal socio-economic and socio-cultural activities and cause loss of life and property that cannot be managed with local resources alone. All natural disasters directly or indirectly linked to meteorological conditions are classified as hydro-meteorological disasters.

Main Types of Hydro-Meteorological Disasters

The most common hydro-meteorological events include:

• Floods and inundations: Water surges caused by sudden or prolonged rainfall increasing surface water levels.
• Storms hail and heavy snow events: Short duration high intensity events resulting from the accumulation of meteorological energy and increased atmospheric water vapor.
• Drought: The emergence of water scarcity due to prolonged lack of precipitation.
• Forest fires: Fires triggered in association with meteorological and climatic conditions.

Frequency and Impacts of Hydro-Meteorological Disasters

Hydro-meteorological disasters cause significant loss of life and property and disrupt socio-economic activities. The increasing frequency of these events cannot be explained by climate change alone; human-induced factors also amplify their impacts. Events such as floods storms hail heavy snow drought and forest fires occur frequently and result in severe losses.

Factors Amplifying Disaster Impacts

• Unplanned and inappropriate urbanization unregulated construction
• Weak infrastructure and poorly maintained older buildings
• Low quality building stock
• Administrative and political pressures
• Lack of early warning systems
• Low preparedness capacity (failure to take preventive measures or negligence leading to increased consequences)

These factors intensify the impacts of hydro-meteorological disasters originating from natural processes and increase societal risk.

Relationship with Climate Change

Global climate change affects the frequency intensity and scale of hydro-meteorological disasters. Increased atmospheric water vapor can alter precipitation patterns and lead to more frequent extreme weather events. The likelihood and impacts of droughts excessive rainfall storms and tornadoes are being reshaped as a consequence of climate change.

Disaster Management and Early Warning Systems

To reduce the negative impacts of hydro-meteorological disasters disaster management and early warning systems are developed. Meteorological observations numerical weather prediction models and alert mechanisms serve as primary tools for forecasting disasters mitigating risks and implementing necessary precautions. Institutions such as the General Directorate of Meteorology contribute to the risk reduction chain by sharing forecast and early warning information with the public and relevant organizations.
