Brunt-Vaisala frequency of planets d 2 ( z z 0 )= 0 An air parcel moves according to the spring equation: dt ( z z 0 )+ N 2 = g N is called the Brunt-Vaisala frequency, given by: N T ( a ) Temperature is assumed to be a linear

An air parcel moves according to the spring equation: N is called the Brunt-Vaisala frequency, given by: Temperature is assumed to be a linear function: Gamma_a is the adiabatic lapse rate: So we use MATLAB to solve the spring equation for three planets: Earth, Mars, and Jupiter, using Runge-Kutta. The slope Gamma is called the lapse rate, measured in K/m
