rtr_mixing: Relative Thermal Resistance to Mixing (RTRM)

Description Usage Arguments Value References See Also

View source: R/rtr_mixing.R

Description

This function estimate RTRM - Another important aspect of stratification in freshwater is that the change in density of water becomes greater as temperature increases. Thus, a few degrees difference between surface and bottom at high temperature will provide more stability (resistance to mixing) than the same degree change at low temperature. This is illustrated by the term relative thermal resistance to mixing (RTRM), which compares the density gradient against the density gradient between 4 and 5 degrees Celsius.
