There has been little air frost, in which the minimum temperature falls below freezing.

There will be a minimum temperature, however, wherein the rate of deposition becomes faster than the rate at which unreacted silane arrives at the surface.

He further goes on to mention how the criterion for calm was changed while the global trend for minimum temperature remained unchanged.

The 10th percentile temperature corresponds to the minimum temperature that would be reached no more than 3 days out of 30 for the month (decile).

Since film boiling occurs after nucleate boiling, the minimum temperature for film boiling should have a proportional dependence on the surface tension.
