尺度相互作用对飑线区域功能平衡的影响
EFFECT OF SCALE INTERACTIONS ON THE KINETIC ENERGY BUDGET OVER THE REGION OF SQUALL LINES
-
摘要: 本文利用一组反映尺度相互作用的动能平衡方程,着重分析了1983年3月14日珠江三角洲地区飑线发生时,尺度相互作用对飑线所在区域动能平衡的影响。并通过对动能平衡的时间演变分析,讨论了飑线的前期、发生期及后期能量过程的差异以及飑线区和邻近的无对流活动区动能平衡过程。Abstract: This paper applies a set of kinetic energy budget equations accounting for meso-synoptic scale interactions, which are similar to those developed by Carney et al. (1986) , to a case study for a squall line occurred in March of 1981, over the Pearl River Delta in South China.The meso-synoptic scale interactions are discussed in conjunction with the kinetic energy balance during the process of the severe storm.
