Abstract

The invention discloses a method and system for simulating an ice cloud growth process, and the method comprises the steps: constructing an ice cloud particle spectrum distribution database and a non-spherical ice cloud particle scattering database, wherein the ice cloud particle spectrum distribution database comprises ice cloud particle observation data, and the non-spherical ice cloud particlescattering database comprises ice cloud particle scattering characteristic parameters; and according to the ice cloud particle spectrum distribution database and the non-spherical ice cloud particle scattering database, calculating a fitting relationship between the ice cloud optical characteristic parameters and the ice cloud macroscopic physical quantities, and determining a fitting coefficient,wherein the ice cloud optical characteristic parameters comprise the ice cloud extinction efficiency, ice cloud asymmetry factors and the ice cloud single scattering albedo, and the ice cloud macroscopic physical quantities comprise the ice cloud ice water content and the ice cloud average effective radius; and applying the fitting coefficient to a radiation transmission model, and simulating theice cloud growth process. According to the method, the accuracy of ice cloud optical characteristic expression in an existing climate mode is improved, and global-scale ice cloud micro-physical parameters can be effectively inverted.

Description

technical field [0001] The present application relates to the field of climate models, in particular to a method and system for simulating the growth process of ice clouds. Background technique [0002] As an important medium for the transmission of heat and water vapor, ice clouds play an important role in the surface radiation balance and the earth's energy balance. Studying the growth process of ice clouds is of great significance to the simulation of global climate change and the early warning of meteorological disasters. At present, in climate models, the parameterization scheme of single-shape particles or multi-shape particles is often used to describe the optical and radiation characteristics of ice clouds. The parameterization scheme of single-shaped ice cloud particles usually uses regular-shaped ice cloud particles, which is difficult to represent most of the optical characteristics of ice clouds; the idea of ​​multi-shaped particle parameterization scheme is to ...
