摘要

摘要: 利用我国第6～9次北极科学考察期间获取的大气探空资料，分析了北极季节冰区边界层逆温的时空变化特征及其成因。分析发现：(1)边界层逆温具有较强的年际变化和空间变化，高纬度密集冰区观测到更多的强逆温现象，逆温厚度与逆温层温差呈显著的对数关系；(2)不同年份边界层逆温的主要成因有所差别：海冰分布的差异导致不同年份的边界层逆温特征不同；表面融化、辐射冷却、多层云的结构和暖平流对不同冰情年份边界层逆温的贡献程度不同；(3)开阔水域和冰区边界层逆温的成因不同。表面融化和空气平流对冰区边界层逆温的形成起着非常重要的作用，而辐射冷却是开阔水域边界层逆温的主要成因之一。

Abstract: The GPS radiosonde data obtained during the 6th to 9th Chinese National Arctic Research Expedition was used to analyze the spatial and temporal variation characteristics of boundary layer temperature inversions over the seasonal ice zone in Arctic. The results show that: (1) There were strong interannual and spatial changes in the temperature inversions. There were more strong inversions over the pack ice zone at high latitude. And the thickness of inversions and the temperature change through the inversions had a significant logarithmic relationship. (2) The main factors controlling inversion properties were various in different years. The differences in sea ice cover leaded to different characteristics of inversions. Surface melt, radiative cooling, multi-layer cloud and warm-air advection provided different degrees of contribution to inversions in different years. (3) There were different reasons over the open water and sea ice zone. Both surface melt and warm-air advection played a very important role in the formation of inversions in sea ice zone. However, radiative cooling was one of the main factors in the generation of inversions over the open water.
