Description
Return rainfall rate in millimetres per hour.
Atmospheric state formulas depend on absolute temperature, pressure reference, water mass/volume bases and layer assumptions. Local adiabatic, hydrostatic or precipitation terms can illustrate a supplied model without reconstructing an actual profile, validating an instrument or predicting weather hazards.
Return rainfall rate in millimetres per hour.
When to use this tool
Use Precipitation Rate Depth Interval Factor when checking the stated atmospheric pressure, temperature, humidity or water-basis term.
How to use the tool and how it works
- Enter depthMillimetres, elapsedMinutes. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read millimetresPerHour. Use the output convention below.
Return rainfall rate in millimetres per hour. Require depthMillimetres >= 0 and elapsedMinutes > 0; rate = 60*depth/elapsed.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| depthMillimetres | Depth Millimetres | Required. Finite number; minimum 0. |
| elapsedMinutes | Elapsed Minutes | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| millimetresPerHour | Millimetres Per Hour | Required. Finite number. |

}Limitations and assumptions
- This is an interval-average rate, not an intensity time series, forecast or flood-risk assessment.
- 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
Use verified observations and an appropriate complete thermodynamic/profile analysis with explicit units, references and moisture assumptions for meteorological conclusions.
