In an era of increasing climate volatility, understanding the patterns and impacts of extreme weather events is more critical than ever. As an Information Systems Officer based in Juba, I recently developed an ArcGIS Dashboard that visualizes Extreme Weather Events using authoritative data from the World Meteorological Organization (WMO).
🔍 Why This Dashboard?
Extreme weather—ranging from floods and droughts to heatwaves and tropical cyclones—has become more frequent and intense due to climate change. The goal of this dashboard is to:
- Visualize global and regional trends in extreme weather events.
- Highlight vulnerable regions and populations.
- Support decision-makers with real-time, data-driven insights.
📊 What the Dashboard Shows
The dashboard integrates WMO datasets and presents them through interactive maps, charts, and filters. Key features include:
- Global Map of Events: A dynamic map showing the geographic distribution of extreme weather events over time.
- Event Type Filters: Users can filter by event type (e.g., floods, droughts, storms, heatwaves).
- Temporal Trends: Line graphs and bar charts show how the frequency and severity of events have changed over the years.
- Impact Metrics: Where available, the dashboard includes data on casualties, economic losses, and affected populations.
🌐 Data Source: WMO
The World Meteorological Organization provides high-quality, standardized data on weather and climate. By leveraging this data, the dashboard ensures accuracy and global comparability.
💡 Use Cases
This dashboard can be a valuable tool for:
- Humanitarian agencies planning disaster response.
- Policy makers crafting climate adaptation strategies.
- Researchers and journalists seeking reliable visualizations.
- General public interested in understanding climate risks.
🛠️ Tools & Technologies
- ArcGIS Online for dashboard creation and spatial analysis.
- WMO APIs and datasets for data sourcing.
- Python and Excel for data preprocessing and cleaning.
