We recently had an unusual phenomenon, when a cold front dropped the temperature by 9° C in a matter of about two minutes. This was confirmed by both my Davis and Oregon stations. In both cases, Weather Display showed the drop over about five minutes, with a slight delay due to the thermal inertia of the sensors.
WeatherFlow took over an hour to respond to the change of temperature. I believe this to be due to the thermal inertia of AIR with the mass of the batteries.
The question is whether this slow response time to changes of temperature is significant. My guess is that it probably isn’t under most circumstances. How often do weather fronts proceed as rapidly as in the case that I’m citing?
For the anecdote, the sudden change of temperature created a significant mist as it was accompanied by an increase of relative humidity from about 50 percent to over 95 percent in the same timeframe, as shown on both legacy weather stations.
