The interaction between the low-frequency atmospheric oscillation(Madden-Julian Oscillation,MJO) and the diabatic heating over the Qinghai-Xizang Plateau(QXP) from March to June is *** results show that there are respectively two and one wave trains around the QXP during the onset of the South China Sea monsoon in strong and weak monsoon *** locations and strength of the wave train propagation differ between the strong and weak monsoon *** diabatic heating of the QXP prevents the low-frequency oscillation,the wave train of interaction between the diabatic heating and the zonal wind MJO propagates along the west and east of the QXP in the strong monsoon *** distribution of the wave train interaction between the diabatic heating and the zonal wind MJO traverses the QXP and coincides with the location of the southern and northern upper-level jet streams,showing that they are remarkably *** interesting and notable phenomenon is that the interaction between diabatic heating and the zonal wind MJO over the QXP suddenly disappears during the monsoon onset in weak monsoon years.

Based on hourly precipitation from national surface stations,persistent heavy rainfall events(PHREs)over the Sichuan Basin(SCB)are explored during the warm season(May to September)from 2000 to 2015 to compare synoptic circulations and maintenance mechanisms between different PHRE *** are two main types of PHREs:one is characterized by a rain belt west of 106°E over the SCB(WSB-PHREs),and the other features a rain belt east of 106°E over the SCB(ESB-PHREs).In total,there are 18 ESB-PHREs and 10 WSB-PHREs during the study ***,the rain belts of WSB-PHREs are along the terrain distribution east of the Tibetan Plateau,while the precipitation intensity of ESB-PHREs is *** the two types of PHREs,the shortwave trough over the SCB and the western Pacific subtropical high act as their favorable background environments,particularly for *** water vapor of WSB-PHREs is mainly transported from the South China Sea,whereas for ESB-PHREs the South China Sea and Bay of Bengal are their main moisture *** composite vorticity budgets of southwest vortices during their mature stage indicate that the convergence effect is a dominant factor for maintaining the two types of PHREs,and the strong vertical vorticity advection is also favorable,but the relative contribution of vertical advection is larger for WSB-PHREs.

Based on CMORPH precipitation estimates and ERA5 reanalysis data,this study investigates the mechanisms accounting for the repeated occurrence of torrential rainfall over South Thailand in early January 2017,which induced the strongest floods over Ko Samui and Ko Phangan in the last almost 30 *** is found that the maintenance of a northeastward-moving mesoscale vortex that formed southwest of the Indochina Peninsula was the direct reason for the series of torrential rainfall *** of the vorticity budget illustrates that convergence-related horizontal shrinking was the most favorable factor for the maintenance of the *** was the second most favorable factor,whereas horizontal and vertical transport mainly caused a net export of cyclonic vorticity from the vortex’s three-dimensional range,which was detrimental for its *** analysis indicates that tilting and vertical vorticity transport were sensitive to the vortex’s displacement and the enhancement of cyclonic vorticity at lower levels around the vortex,respectively,as the two factors showed completely different effects on the persistence of the vortex during two different stages.

Different from other domestic and foreign research in which the optimum interpolation(OI) merging algorithm is commonly used,this paper constructs the non-Gaussian model for generalized variational precipitation data merging research based on the non-Gaussianity of precipitation data. For CMORPH data correction,the probability density function( PDF) matching method is adopted,during which the GAMMA function fitting is utilized,and the generalized variational merging based on non-Gaussian model is used to merge corrected CMORPH precipitation data and station ground observation precipitation data. Meanwhile,we carry out an experiment on CMORPH precipitation data correction and the merging of multisource precipitation data based on non-Gaussian model. By measuring the structural similarity between the merged field and the reference field,we get a merging method that can better retain useful " outliers" which represent weather phenomena. The experimental results accord with our expectations.

精准的风速预报是风电功率预测的基础,风场的预报评估是提升风电功率预测水平的有效途径之一。基于中尺度数值天气预报模式(weather research and forecast,WRF),采用风险评分、相关系数及均方根误差等定量分析指标,结合西北电网数值预报结果,开展6种大气边界层参数化方案的适用性研究。结果表明:YSU(Yonsei University)方案预报的地面纬向风平均相关系数最高为0.87、均方根误差最低仅1.0 m/s,且地面经向风、850 hPa和500 hPa高度场、以及500 hPa风速预报效果均最优,是提升西北电网风场预报的最优边界层方案。本研究为西北电网风场(以及其他气象要素)预报效果的提升指明了方向。
