Executive Summary
This thesis explores long-range atmosphere-ocean forecasting to support undersea warfare (USW) operations in the western North Pacific. It assesses the potential to predict sonic layer depth (SLD) at lead times of one to several months using sea surface temperature (SST) as a predictor. The study demonstrates that these probabilistic forecasts significantly improve upon existing climatology products, enhancing Navy meteorology and oceanography support for USW.
Why It Matters
This document is crucial for defense analysts as it details advanced environmental forecasting methods directly impacting undersea warfare operations, particularly anti-submarine warfare, in a strategically vital region. Understanding these predictive capabilities can inform naval strategy, resource allocation, and operational planning for future conflicts.
Key Takeaways
- Long-range forecasts of sonic layer depth (SLD) in the western North Pacific are achievable using sea surface temperature (SST) as a predictor.
- Probabilistic forecasts developed in this study offer a clear improvement over current long-term mean climatology products for undersea warfare (USW) planning.
- Integrating advanced climate data and forecasting methods can significantly enhance the Navy's meteorology and oceanography support for USW operations.
- The study focuses on the East China Sea and ANNUALEX regions, highlighting specific areas for improved operational planning.
- The methodology involves tercile matching and composite analysis forecast (CAF) methods for hindcasting and forecasting SLD.
Strategic Relevance
Accurate long-range atmosphere-ocean forecasting is tactically and strategically vital for undersea warfare, especially in contested maritime environments like the Western North Pacific. Predicting sonic layer depth allows for optimized anti-submarine warfare (ASW) operations, enhancing stealth, detection, and weapon effectiveness, thereby providing a significant operational advantage.
