Q1. Describe your experience with Numerical Weather Prediction (NWP) models. Which models have you used, and how do you evaluate their output for operational forecasting?
Why you'll be asked this: This question assesses your foundational technical skills, practical experience with industry-standard tools, and critical thinking in model interpretation. Interviewers want to know if you can apply theoretical knowledge to real-world forecasting.
Start by listing specific NWP models you're proficient with (e.g., WRF, GFS, ECMWF, GEM). Explain your experience in running, initializing, or post-processing these models. Detail your methodology for evaluating model output, including comparing different models, analyzing ensemble forecasts, identifying biases, and cross-referencing with observational data (radar, satellite, soundings). Mention how you use this evaluation to refine your forecast confidence and identify potential forecast busts.
- Vague answers without naming specific models or software.
- Inability to discuss model limitations or biases.
- Focusing only on theoretical knowledge without practical application.
- Not mentioning how you integrate model output with other data sources.
- How do you handle conflicting outputs from different NWP models?
- Can you describe a time a model significantly underperformed, and how you adjusted your forecast?
- What role does machine learning or AI play in your approach to NWP model interpretation?
