When Will Ukrainian Ground Be Frozen Enough For Tanks To Attack?

According to engineering and environmental experts, probably by the end of December. JL

At Svatove, the average temperature for December is -3C. We get a frozen ground depth of about 40 cm by the end of the month. There needs to be to be about 15cm of frozen ground for a heavy truck, more so for a tank but less than 40cm. So in Svatove the ground will most definitely be hard enough by the end of the month. Other factors such as snow cover do affect the freezing depth but not very much as long as the air temperature stays below freezing. No snow means faster freezingI am not an expert on frozen soils but I happen to know two of them and they helped me figure this out. The calculations used in this thread are based on average monthly temperatures and not current conditions. Let's look at Svatove.

 

The average temperature for December is -3C.

 

Based off the formula provided by my cryogeologist friend, i.e. 0.23*sqr(3), we get a frozen ground depth of about 40 cm by the end of the month. According to him there needs to be to be about 15cm of frozen ground for a heavy truck, more so for a tank but less than 40cm.

 

So in Svatove the ground will most definitely be hard enough by the end of the month. Other factors such as snow cover do affect the freezing depth but not very much as long as the air temperature stays below freezing. No snow means faster freezing however.
