Conventional weather forecasts miss localised convective events. Marine Weather Intelligence is developing a satellite-based nowcasting system to provide a 30–90 minute alert window for offshore teams operating in storm-prone regions.
The Core Challenge
At sea, thunderstorms demand rapid decision-making and precise forecasting. This is particularly critical in storm-prone regions like the Gulf of Guinea, where the Intertropical Convergence Zone and warm ocean waters create conditions for sudden, high-intensity convective storms. For offshore heavy lift operations, accurate storm prediction is essential for safety and timing.
Technology Approach
The proof of concept leverages satellite-based infrared imagery to detect convective zones as they form. The system applies optical flow techniques to track cloud-top temperature changes, which indicate thunderstorm growth and movement.
Rather than relying on broad numerical weather prediction models, the system focuses on the fine-scale storm activity that directly impacts offshore operations.
The solution delivers short-range forecasts tailored to clients’ operational areas, providing critical lead time for risk mitigation.
Operational Benefits
The nowcasting system is designed to empower offshore teams to:
- Adjust or postpone sensitive marine operations ahead of storm arrival
- Reroute vessels to safer waters with sufficient lead time
- Implement safety protocols with greater confidence and less uncertainty
Why Conventional Forecasts Fall Short
Most global weather models operate at resolutions too coarse to capture localised convective events. A squall cell can develop, intensify, and dissipate within a few hours, often within the gaps of model update cycles.
“Instead of relying on broad forecasts, we focus on the fine-scale storm activity that directly impacts offshore operations.”
Satellite imagery provides continuous, wide-area monitoring that bridges this gap, particularly in oceanic regions with limited ground-based observational infrastructure.
