| 文章着眼于海洋温带气旋爆发性发展热力结构的影响效应问题。通过数值试验的结果表明,温带气旋发展状况对于垂直加热廓线分布具有突出的敏感性,若将垂直加热廓线“形变”,则可能导致海洋气旋的爆发性发展,并构成类似观测到的“气象炸弹”动力,热力结构,即“上干下湿”,“上冷下暖”的不稳定层结或“抽吸”结构,急流轴“断裂”形成的非地转偏差特征。从而揭示了垂直加热廓线特征在海洋气旋发展诸影响因子中的关键作用以及潜热释放分布与海洋气旋动力、热力结构形成的机理。 |
| 英文摘要: |
| In this paper, the principal results are the following:the explosively deepening of marine cyclone is very sensitivity for the vertical heating profile, if the profile is adjusted to the suitable state, the explosive development of the cyclone appears and the thermodynamic struction of the cyclone or the state of upper jet stream in the model is similar to observational fact. This suggest that the state of the vertical heating profile plays an important role in explosively deepening of marine extratropical cyclone. |
