In this sentence does thermal indices refer to the warming trends in the weather?

The ground snow load figure plus the flat roof snow load along with the exposure and thermal indices need to be figured in any formulas.

indices? means index , so a thermal index would be
oh never mind to much typing and make my head hurt.
sounds like they are talking about how fast snow would melt off of a roof and at given temp..

of course i will admit i could be wrong since i dont know what yoru reading

ok i thought i would look it up,
"About Thermal Index


A thermal index is a measure of atmospheric stability/instability. To determine for a given altitude, subtract the temperature of the lifted airmass from the measured air temperature. If the result is negative, actual air is warmer than standard and should continue to rise. If the result is positive, it indicates that the air aloft is warmer than the rising air would be at that altitude and a thermal would stop rising because it has encountered warmer, less dense air. Dry adiabatic rate of cooling is: 5.4 degress Fahrenheit per 1,000 feet. "

I know what thermal index is. The word indices is what is throwing me. Is that the same as index? I looked up thermal indices and it took me to a page about pasturizing milk-

Indices means more than one index. Meaning in this case the person doing this is checking more than one source.
