WebThe values of the constants C and n depend on the geometry of the surface and the flow regime, which is characterized by the range of the Rayleigh number. The value of n is usually n = 1/4 for laminar flow and n = 1/3 for turbulent flow. The Rayleigh number is defined as: where: g is the acceleration due to Earth’s gravity WebJun 4, 2024 · meaning that ∼ 84 % of the photons don't scatter. However, in the Rayleigh regime, the scattering cross section goes a σ ∝ λ − 4. That means that the cross section as seen by a red photon with λ = 700 n m is ( 700 / 420) 4 ≃ 7.7 times smaller, so now the probability is only.

"WebIn the new approach presented in this work, the aim was instead to identify signatures that particles in the vicinity of cloud top are small enough to scatter in the Rayleigh regime. For this, the key approach is searching for a Rayleigh plateau, i.e., a large enough region where the vertical gradient of DFR remains below a certain threshold. " - Rayleigh regime
