- Heavy Rainfall and Flooding: ML models are being used to predict the likelihood of heavy rainfall and subsequent flooding. These models take into account a wide range of variables, including soil moisture, river levels, and atmospheric conditions, to provide more accurate flood warnings.
- Heatwaves and Cold Snaps: AI models can forecast prolonged periods of extreme heat or cold by analyzing atmospheric pressure patterns, sea surface temperatures, and other climatic factors.
By providing more accurate predictions of these events, AI and ML can help communities prepare better, reducing the risk to lives and property.
AI and ML for Long-Term Climate Predictions
While traditional weather models focus on short-term forecasts, AI and ML are also proving valuable for long-term climate predictions. These models analyze historical climate data and use it to predict future trends and anomalies. This is particularly important for understanding the long-term impacts of climate change.
For example, ML models have shown promise in predicting the El Niño Southern Oscillation (ENSO) up to three years in advance. ENSO is a major climate driver that affects weather patterns across the globe. Accurate predictions of ENSO can help farmers plan their crops, water resource managers prepare for droughts, and governments plan for potential disaster response.
Case Studies and Real-World Applications:
There are numerous real-world examples of AI and ML in Meteorology improving weather forecasting and climate predictions. One notable case is the “Mission Mausam” initiative in India.
