细菌气溶胶在大气冰核核化过程中作用的研究进展

Progress of research on ice nucleation active bacterial aerosols' role in atmospheric ice nucleation

介绍了大气中细菌气溶胶的种类和浓度分布的变化特征,对冰核细菌促进冰核核化的分子生物学机制,影响成冰活性的因素以及冰核在大气冰核核化过程中作用的研究进展等做了重点介绍,对冰核细菌的生物学、分子生物学和形态学及其实际应用等方面的研究进展也做了讨论,同时也指出了今后需要进一步研究的问题,尤其是生物冰核在云和降水中作用方面的问题.

It was well known that ice nucleation is one of the most basic processes that lead to precipitation.This mini-review paper focused on respects of INA bacterial aerosols： concentration and dynamic macroscopically in atmosphere;molecular mechanic progresses,properties and factors of heterogeneous ice nucleation in lab and role on precipitation.However,there is no systemic and confirmed nucleation theory basing on characteristics of micro-physiology and/or physical chemistry of INA bacteria.Moreover it had been remained to research how deeply INA bacteria nucleating works on meteorologic process.
