LLJ：低空急流

“低空急流”在科技文献中常被缩写为“LLJ”，这一简称便于书写和使用，尤其在气象与海洋科学领域的研究中非常普遍。低空急流作为重要的中低层大气现象，对区域天气系统、降水分布及海洋环流具有显著影响，因此其缩写形式LLJ在相关学术交流与论文撰写中应用广泛。

The interaction between the southern low level jet and weaker cold air of ground layer from northern North China led to initiation and development of the cloud clusters.
该云团的形成和发展，是偏南风低空急流(LLJ)与华北北部南下的近地面层弱冷空气相互作用的结果。
