Exhale Condensation Calculator

If the temperature is low enough or the humidity high, you can observe condensation (i.e., "fog") forming in your exhaled breath. This calculator estimates whether your exhaled breath will condense, and if so, the range of mixing ratios for which the "fog" will form and the maximum condensed water content (the higher it is, the "thicker" the condensation).

If you're interested, there is a much more detailed explanations of the condensation process.

Exhaled Condensation Calculator
Using the above equations, we can calculate whether the exhaled air will condense. Enter the conditions of the outside air (and modify the exhaled air parameters if you wish), to see whether your breath will condense, or not.

Snow probability calculator

Based on the analysis of whether falling snow will melt as it descends, it is possible to estimate the probability with which falling precipitation will be snow.
