Description
Return temperature minus each threshold, classify equality at the cold limit as snow-side and equality at the warm limit as rain-side, otherwise transition.
Degree-time indices accumulate temperature differences above or below a supplied threshold. Multiplying by a model coefficient creates a conditional estimate whose units depend on the time basis and coefficient.
Return temperature minus each threshold, classify equality at the cold limit as snow-side and equality at the warm limit as rain-side, otherwise transition.
When to use this tool
Use Precipitation Phase Explicit Threshold Gap when you need one explicit temperature-index or threshold component.
How to use the tool and how it works
- Enter temperature, snowThreshold, rainThreshold. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read coldMargin, warmMargin, category. Use the output convention below.
Require rainThreshold above snowThreshold. Return temperature minus each threshold, classify equality at the cold limit as snow-side and equality at the warm limit as rain-side, otherwise transition.1

}Limitations and assumptions
- Temperatures share one scale; labels only apply supplied thresholds and do not predict actual precipitation phase, icing, or road safety.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Check the threshold, coefficient calibration, and complete energy or environmental model separately.
