1963年,爱德华`洛伦茨开发了一个简化的大气对流数学模型: x' = σ(y-x) y' = x(ρ-z)-y z' = xy-βz 程描述了三个量随时间的变化率:x'流体流速率变化,y'流体密度变化,z'流体垂直温度变化。普朗特数σ(动量传输及热量传输速率的比),瑞利数ρ(自然对流和扩散热量、质量传递之比),热膨胀系数β。pic.twitter.com/YjOOxZ5iBI

Old friend of yours, @sTeamTraen?
I can feel my positivity improving by the minute.
Lorenz’s model is a reduction of Saltzman’s equations, resulting in a three-variable ODEs model from a high-dimensional one !
3 point equilibria
Lorenz ... not to be confused with ... Lorentz (https://en.wikipedia.org/wiki/Hendrik_Lorentz …)
