Introduction

Artificial Intelligence (AI) is increasingly transforming weather forecasting by leveraging machine learning algorithms and large datasets to generate faster and more efficient predictions. AI-based models such as GraphCast (Google DeepMind) and Pangu-Weather (Huawei) have shown remarkable accuracy in routine forecasting. However, their ability to predict record-breaking extreme weather events remains limited, highlighting the challenges of applying AI to complex atmospheric systems.

Opportunities of AI in Weather Forecasting

1. Faster and Cost-Effective Forecasting

  • AI models can generate forecasts in minutes compared to computationally intensive Numerical Weather Prediction (NWP) models.
  • Reduces computational costs and energy consumption.

2. Improved Routine Forecast Accuracy

  • AI excels in short- to medium-range forecasting by identifying patterns in historical data.
  • Enhances predictions of temperature, rainfall, wind, and cyclone tracks.

3. Better Early Warning Systems

  • AI can integrate data from satellites, radars, and sensors for real-time monitoring.
  • Strengthens disaster preparedness and climate adaptation.

4. Support for Sectoral Applications

  • Benefits agriculture, aviation, shipping, water management, and urban planning.
  • Enables location-specific advisories.

5. Data Assimilation and Downscaling

  • AI helps improve spatial resolution and local-scale forecasting.

Value Addition

WMO: Artificial Intelligence can complement, rather than replace, traditional meteorological models.


Limitations of AI in Weather Forecasting

1. Dependence on Historical Data

  • AI models learn from past datasets and may struggle with unprecedented conditions outside their training range.
  • Climate change is altering historical weather patterns.

2. Black-Box Nature

  • Many AI models lack interpretability, making it difficult to understand forecast errors.
  • Limits scientific validation and trust.

3. Data Quality Constraints

  • Forecast accuracy depends on the quality and representativeness of input data.
  • Sparse observations in oceans and developing regions affect performance.

4. Limited Physical Understanding

  • AI identifies correlations but does not inherently incorporate atmospheric physics.
  • May fail to capture complex interactions among climate systems.

Why AI Underperforms in Predicting Record-Breaking Extreme Events

1. Rarity of Extreme Events

  • Record-breaking heatwaves, cloudbursts, and cyclones occur infrequently.
  • AI models have limited examples to learn from.

2. Non-Stationarity Due to Climate Change

  • Rising temperatures and changing atmospheric dynamics create conditions not represented in historical data.
  • This weakens the predictive ability of data-driven models.

3. Extreme Events Involve Non-Linear Dynamics

  • Small changes in initial conditions can lead to disproportionately large impacts.
  • Atmospheric systems exhibit chaotic behaviour, limiting predictability.

4. Inadequate Representation of Tail Risks

  • AI models often optimize for average performance rather than rare, high-impact events.
  • Consequently, they may underestimate extremes.

Example: AI models may accurately predict regular monsoon rainfall but struggle to anticipate unprecedented events such as extreme cloudbursts or marine heatwaves.

Conclusion

AI has immense potential to revolutionize weather forecasting through faster computation, improved routine predictions, and enhanced early warning systems. However, record-breaking extreme events remain difficult to predict due to their rarity, non-linearity, and the changing climate. The future lies in hybrid models that combine AI's data-processing strengths with the physical foundations of traditional meteorological models.
