Following a series of relatively warm days, we had a sudden (over a period of a few hours) drop in temperature and things then stayed very cold for several days. This led me to wonder how fast the ground would cool under such circumstances.
For the purposes of getting a simple, quick feel for the effect of the air temperature change, we’ll look at a somewhat simplified version of the actual events. Of course this result won’t exactly match what happened in real life, but it will provide a reasonable estimate.
