摘要

摘要: 利用非静力平衡中尺度数值模式MM5v3对发生在2001年3月7～8日的南岭山地浓雾进行数值研究,结合外场综合观测资料,分析浓雾的发生、发展和消散机制。结果表明,在大范围的主体层状云系到来之前,低层的偏南暖湿气流沿山坡爬升冷却凝结形成爬坡雾,提早了地面浓雾出现的时间;大范围层状云系在山头接地形成了地面的浓雾。随后锋面逆温促进了低云和浓雾的长期维持与发展。模拟雾的强度、出现时间、含水量和温度、湿度随时间的演变与实测基本吻合。表明了中尺度模式预报山地浓雾的潜在能力。

Abstract: Using the non-hydrostatic meso-scale model MM5v3,dense fog that occurred from March 7 to March 8,2001 over the Nanling Mts.area was studied.With integrated field experiments observations,the occurrence,development and lift mechanism of fog were analyzed.The results indicate that before the coming of stratiform clouds,southerly warm and wet air ascended along mountainside and cooling condensation formed mountain fog.Then fog was formed by the stratiform on cloud-contacting mountaintop.Front inversion layer accelerated the development and longer duration of the lower cloud and fog.The intensity,occurrence time,mass content and the variation of temperature and relative humidity of the fog were in accordance with those of the observation.It showed that the meso-scale model has the potential to forecast mountain fog.
