Layered cloud operation condition discrimination method based on ice water surface saturated water vapor density difference

The invention discloses a layered cloud operation condition discrimination method based on an ice water surface saturated water vapor density difference. The method comprises the following steps: collecting parameters of a particle image in cloud; calculating the saturated water vapor density difference of the ice water surface in the cloud through the parameters; and taking the conditions that the atmospheric environment temperature is lower than-4 DEG C, the relative humidity is lower than 100%, the saturated water vapor density difference value of the ice water surface is greater than 0.05 g m and the proportion of the supercooled liquid drops at the corresponding moment is lower than 10% as the judgment conditions of the potential area of the layered cloud artificial precipitation enhancement operation. The method is high in recognition precision and high in operability, can be used for real-time recognition of layered cloud artificial precipitation enhancement operation conditions by artificial inf
