Light Scattering Characteristics of Ice Crystal Particle Clouds
To predict complex weather changes accurately and within a reasonable timeframe in practical applications, ice crystal particle cloud models were constructed using a combination of ellipsoidal hexagonal plates, ellipsoidal tetrahedra, hexagonal tetrahedral plate, and ellipsoidal hexagonal tetrahedra plate. An analytical function of the standard gamma distribution was used to approximate the spectral distribution of the ice crystal particle clouds. The extinction coefficient, absorption coefficient, and a single scattering albedo of the newly constructed cloud model were analyzed, and the effects of incident wavelength and cloud model on the function of the scattering phase were studied. We built a cold chamber to grow ice crystal particles and conducted experiments on their generation at different temperatures. We used a three-band atmospheric integral turbidity meter to measure the extinction coefficient and scattering coefficient of the newly constructed ice crystal model. Our results showed that the scattering phase functions of the four newly established models for ice crystal particle clouds exhibited peaks within the ranges of 22o‒46o and 140o‒160o, which were results similar to those of the classical MODIS6 ice crystal particle cloud scattering model. As the experimental time changes, the extinction and absorption coefficients show multiple extreme values and exhibit randomness. However, the experimental and simulation values of the four newly established models are in good agreement, which verifies the rationality of the proposed cloud model. The results also further supplement and improve the ice crystal particle cloud model, select appropriate ice crystal particles for cloud modeling, and provide support for the accurate prediction of weather changes.
