英文摘要 | Abstract. Ice particles play an important role in precipitation formation and radiation balance. Therefore, an accurate description of ice initiation in the atmosphere is of great importance for weather prediction models and climate simulations. Despite the abundance of ice crystals in the atmosphere, the mechanisms for their formation remain not well understood. There are two major sets of mechanisms of ice initiation in the atmosphere: primary nucleation and secondary ice production. Secondary ice production occurs in the presence of preexisting ice, which results in an enhancement of the concentration of ice particles. Until present, secondary ice production was mainly associated with the rime-splintering mechanism, known as the Hallett-Mossop process, which is active in a relatively narrow temperature range from -3 °C to -8 °C. The existence of the Hallett-Mossop process was well supported by in-situ observations. The present study provides the first in-situ observation of secondary ice production at temperatures as low as -27 °C, which is well outside the range of the Hallett-Mossop process. This observation expands our knowledge of the temperature range of initiation of secondary ice in clouds. The obtained results are intended to stimulate laboratory and theoretical studies to develop physically based parameterizations for weather prediction and climate models. |
