中文摘要:本文先从理论上讨论低空急流的成因,通过能量方程说明水汽凝结潜热是暴雨过程中形成低空急流的一个主要因子,并提出了相应的物理机制。然后介绍了用三层原始方程模式模拟低空急流形成的过程,其结果与理论分析及实际情况都有很好的一致性。
 
MECHANISM OF DEVELOPMENT OF LOW-LEVEL JET STREAMS AND ITS NUMERICAL MODELLING
Abstract:A theoretical discussion based on the energy equations suggests that the latent heat of condensation during the rainstorm process is a main factor in the formation of low-level jet streams. A physical mechanism is proposed. Then a three-layer numerical model using the primitive equations is described,the result of which is found to be consistent with the theoretical analysis and observed facts.
