皖东两次强对流风暴过程的动力学诊断

对１９９６年夏季发生在副高西北侧和副高内部的皖东沿江地区两次强对流风暴过程进行了热力参数和动力学对比诊断，结果表明：两次过程的动力、热力学机制存在显著的差异；引入Ｑ矢量分析后又发现：强雷暴及暴雨区与Ｑ矢量辐合区有较好的对应关系；最后概述了这两类强风暴过程的０－１２小时预报着眼点。     

我国飑线发生条件的研究

使用MICAPS地面气象观测资料和探空资料,对山东省2009—2016年4—9月产生的雷暴大风以500 hPa天气系统为主进行分型,并以低层（850 hPa）中尺度天气系统和地面天气系统为辅对各型雷暴大风进行分类。然后,采用百分位数法统计分析各型雷暴大风发生时的物理诊断量,并给出各物理诊断量的临界值。结果表明：（1）基于500 hPa天气影响系统配置,山东省雷暴大风分为槽前型、槽后型和副高边缘型,再根据雷暴大风落区与850 hPa天气系统的位置关系,又分为切变线辐合类、偏南气流辐合类和偏北气流辐合类3种类型,而根据海平面气压场中天气系统与雷暴大风的位置关系,则将产生雷暴大风的地面天气系统主要归纳为6种类型。（2）将山东省划分为内陆地区和半岛地区,4—6月内陆地区雷暴大风的适用物理诊断量为850 hPa与500 hPa温差（ΔT_850-500）、500 hPa与850 hPa风速差（ΔV_500-850）、风暴强度指数（SSI）和大风指数（WI）,半岛地区代表大气热力和动力综合特征的物理诊断量SSI和WI对雷暴大风的指示性较好。（3）7—8月山东全省,代表大气热力不稳定的物理诊断量即对流有效位能（CAPE）、K指数、抬升指数（LI）、700 hPa与850 hPa假相当位温差（Δθ_se700-850）、强天气威胁指数（SWEAT）,对雷暴大风有较好的指示性。（4）9月山东省雷暴大风主要发生在半岛地区,Δθ_se700-850、SSI、SWEAT和ΔV_500-850对雷暴大风具有较好的指示性。

     

The major research advances of mesoscale weather dynamics in China since 2003

This paper reviews the main theoretical progress of mesoscale weather dynamics since 2003, including： （1） The dynamic mechanisms of balanced and unbalanced flow are applied to study the genesis and development problems of mesoscale circulation. The symmetric instability and transverse-wave instability are analyzed in line and vortex atmosphere convection, and further research has been done on nonlinear convective symmetric instability. The interaction between forced convection and unstable convection and the wave characteristics of mesoscale motion are also discussed. （2） Intermediate atmosphere dynamic boundary layer models are developed. The complicated nonlinear interaction is analyzed theoretically between the atmospheric boundary layer and the free atmosphere. The structure of the topography boundary layer, atmospheric frontogenesis, the structure and circulation of the low-level front and other boundary layer dynamic problems are discussed. （3） The formation and development of meso-β-scale rainstorms under the background of the East-Asia atmosphere circulation are diagnosed with the variation of MPV （moist potential vorticity） anomalies. And some physical vectors are modified and applied in the moist atmosphere.     

泉州市部分石材矿山地质灾害调查分析

针对泉州市4个主要石材采矿带的矿山分布特征及矿山开采状况进行调查分析,认为各矿山采矿场地普遍偏小,以个体开采经营为主,机械化程度低,开采作业较零乱,开采边坡大多数形成高陡的采掘面,缺少安全台阶。各矿山综合治理相对滞后,废石、废碴随意堆放,均存在不同程度安全隐患和潜在的地质灾害,通过分析研究,提出预防建议和对策。

应用二层模式和阻力定律诊断海上20m高度的风和温度场。应用边界层模式和数值天气预报模式实现试报。运用热输送定律计算海上温度,计算结果与实测比较令人相当满意。本文对相似参数的敏感性也作了检验。并指出应用斜压边界层模式的计算大于应用正压模式的结果。     

A review of major progresses in mesoscale dynamic research in China since 1999

Mesoscale research conducted by Chinese meteorologists during the past four years is reviewed.Advances in theoretical studies include (a) mesoscale quasi-balanced and semi-balanced dynamics, derived through scale analysis and the perturbation method which are suitable for describing mesoscale vortices;(b) subcritical instability and vortex-sheet instability; (c) frontal adjustment mechanism and the effect of topography on frontgenesis; and (d) slantwise vorticity development theories, the slantwise vortex equation,and moist potential vorticity (MPV) anomalies with precipitation-related heat and mass sinks and MPV impermeability theorem. From the MPV conservation viewpoint, the transformation mechanism between different scale weather systems is analyzed. Based on the data analysis, a new dew-point front near the periphery of the West Pacific subtropical high is identified. In the light of MPV theory and Q-vector theory, some events associated with torrential rain systems and severe storms are analyzed and diagnosed.Progress in mesoscale numerical simulation has been made in the development of meso-α, meso-β vortices,meso-γ-scale downbursts and precipitation produced by deep convective systems with MM5 and other mesoscale models.

两类低空急流的流量学诊断

根据ＫＲ和ＫＤ方程的各项水平分布，着重讨论伴有暴雨和不伴有暴雨两类低空急流维持的动力过程，指出主要差异在于维持机理不同，尤其是能量转换方向相反，从ＫＤ和ＫＲ的正转换似乎是暴雨发生的必要但非充分条件，同时能量转换的强度和方向不仅决定于涡度场和散度场的相对配置，还与急流的垂直分布形式直接有关。
