Final answer:
The correct method not used by forecasters to predict the weather is using intuition or gut feelings. Forecasting relies on scientific methods such as computer models and historical data analysis.
Step-by-step explanation:
Predicting the weather involves a variety of scientific methods and tools. The method NOT used by forecasters to predict the weather is C) Using intuition or gut feeling. Instead, forecasters employ techniques such as reviewing historical weather patterns, observing the most recent 24-hour weather conditions, and using computer forecasting models. Methods like analyzing tree rings or ice cores are used to predict long-term climate changes rather than daily weather patterns. Scientific forecasting relies on systematically collected data and advanced computational techniques, not on subjective intuition.
