# Cold Wave Probability Cold wave duration hazard refers to the length of days where the daily minimum temperature is less than 5℃ from a centered six day average. The hazard has 3 severity levels (Low, Moderate, High). Low cold wave hazard intensity corresponds to 5 and 6 days, moderate to 7 and 8 days, while high to more than 9 days. For each of the severity levels, cold wave duration hazard is calculated for each of the 12 calendar months. The returned values of the cold wave duration hazard are probabilities of exceeding the above duration thresholds per severity class per calendar month. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.answr.space/api-data-layers/natural-disasters/cold-wave-probability.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
