The Richardson Number is a dimensionless quantity used in fluid mechanics and meteorology to determine the stability of a flow in the atmosphere, particularly in the context of buoyancy and shear forces. It helps to assess whether turbulence will occur in the atmospheric boundary layer by comparing the relative strength of buoyancy forces to the inertial forces caused by wind shear. A high Richardson Number indicates stable conditions, while a low number suggests instability, often leading to turbulent mixing.
congrats on reading the definition of Richardson Number. now let's actually learn it.
