The Math / Science

The Richardson Number (related to Grashof and Reynolds) is the dimensionless number that expresses the ratio of the buoyancy term to the flow gradient term. It is of practical importance in weather forecasting and in investigating density and turbidity currents in oceans, lakes, and reservoirs. The Richardson number can be expressed as a combination of the Grashof and Reynolds numbers.  The formula for the Richardson Number is:

                  `Ri=(Ge)/(Re^2)`

where: 

• Ri is the Richardson Number
• Ge is the Grashof Number
• Re is the Reynolds Number
