| 1 | 一次引发南亚大暴雨的季风低压结构、涡度与水汽收支分析显示文摘对2003年夏季风期间,7月24~28日印度季风槽内季风低压发展西移与阿拉伯海中尺度低压合并引发南亚的一次大暴雨过程进行了诊断分析,探讨了印度季风槽、季风低压的三维结构以及低压区域的涡度、水汽收支.揭示和确认了一些事实:1)印度季风槽区对流层中下层存在明显的风场切变,槽区高温高湿,为单一性质的热带气团,低层为对流不稳定,槽区对应正涡度区;2)季风低压是一较深厚系统.动力结构为低层正涡度,高层负涡度,低层辐合,高层辐散.其西移速度约500 km·d.季风低压北侧整层为深厚的东风,南侧在对流层中低层为西风,在高层为东风.热力结构在低层(700~800 hPa)间存在弱冷区,而中高层几乎为暖心结构.低压对应高湿区,低压中心西侧整层为相对湿度大值区;3)季风低压的发展过程中,低层的辐合场制造正涡度,促进低压的发展;4)低压区水汽强烈辐合,西边界输入量最大.在此研究工作的基础上,作者还比较了夏季风期间南亚印度季风槽和东亚梅雨锋系统的异同. | 孔期 Ghulam Rasul 赵思雄 | 2005 | 气候与环境研究2005，10，3： | 19 |
| 2 | A Diagnostic Study of Heavy Rainfall in Karachi Due to Merging of a Mesoscale Low and a Diffused Tropical Depression during South Asian Summer Monsoon显示文摘This paper presents the results of a diagnostic study of a typical case of very heavy rainfall during the South Asian summer monsoon when a mesoscale low in a desert climate merged with a diffused tropical depression. The former low was located over Pakistan's desert region and the latter depression originated over the Bay of Bengal. Surface and NCEP reanalysis data supported by satellite and radar images were incorporated in the diagnosis. The relationship between the heavy precipitation process and large-scale circulations such as monsoon trough, subtropical high, westerly jet, low level jet and water vapor transport were investigated to further understand the mechanism of this peculiar interaction. It was found that: (1)the mesoscale low developed as a result of cold air advection aloft from northern latitudes and strong convection over the region of humidity convergence on 24 July 2003 over the Indian Rajistan area. (2) On the same day, a low that formed over the Bay of Bengal was transformed into a monsoon depression and moved westward to the mesoscale low which existed over southwest India and the adjoining southeastern parts of Pakistan. (3) Initially, the mesoscale low received moisture supply from both the Bay of Bengal as well as the Arabian Sea, whereas the Bay of Bengal maintained the continuous supply of moisture to the monsoon depression. (4) After the depression crossed central India, the Bay's moisture supply was cut off and the Arabian Sea became the only source of moisture to both the closely located systems. On 27July, both of the systems merged together and the merger resulted in a heavy downpour in the Karachi metropolitan and in its surroundings. (5) With the intensification as well as the southeastward extension of the subtropical high and the shift of the monsoon trough axis from southwest-west to northeast-east,the monsoon depression moved southwestward. In this situation, there existed a very favourable condition for a merger of the two systems in the presence of cross-latitude influence. (6) A number of convective cloud clusters were developed and organized in the mesoscale low. Probably, interactions existed among the multi-scale systems. | Ghulam RASUL Qamar-uz-Zaman CHAUDHRY 赵思雄 曾庆存 齐琳琳 张高英 | 2005 | Advances in Atmospheric Sciences2005，22，3： | 8 |
| 3 | Risk assessment of maize drought disaster in southwest China using the Environmental Policy Integrated Climate model显示文摘The East Asian monsoon has a tremendous impact on agricultural production in China. An assessment of the risk of drought disaster in maize-producing regions is therefore important in ensuring a reduction in such disasters and an increase in food security. A risk assessment model, EPIC(Environmental Policy Integrated Climate) model, for maize drought disasters based on the Erosion Productivity Impact Calculator crop model is proposed for areas with the topographic characteristics of the mountainous karst region in southwest China. This region has one of the highest levels of environmental degradation in China. The results showed that the hazard risk level for the maize zone of southwest China is generally high. Most hazard index values were between 0.4 and 0.5,accounting for 47.32% of total study area. However,the risk level for drought loss was low. Most of the loss rate was <0.1, accounting for 96.24% of the total study area. The three high-risk areas were mainlydistributed in the parallel ridge–valley areas in the east of Sichuan Province, the West Mountain area of Guizhou Province, and the south of Yunnan Province.These results provide a scientific basis and support for the reduction of agricultural drought disasters and an increase in food security in the southwest China maize zone. | JIA Hui-cong PAN Dong-hua LI Jing ZHANG Wan-chang Ghulam RASUL | 2016 | Journal of Mountain Science2016，13，3： | 4 |

| 7 | A Diagnostic Study of Record Heavy Rain in Twin Cities Islāmābad-Rāwalpindi显示文摘Using surface and NCEP reanalysis data along with radar and satellite images, diagnosis has been carried out to probe the reasons for the very heavy rainfall that occurred in Islˉamˉabad-Rˉawalpindi on 23 July 2001. It has been revealed that the sudden evolution of this meso-scale severe weather system was the direct result of strong surface convection in moist and unstable lower layers of the atmosphere. The subsequent rapid development was the combined e?ect of the presence of the mid latitude westerly’s trough in the north and moisture feeding through monsoon ?ow along the Himalayas and also the direct south- westerly current from the Arabian Sea. After the westward shifting of the Sub-Tropical High (STH) from the north of India, the strong divergence zone on its eastern edge contributed positively to the develop- ment of upward motion. Initially the convective systems moved towards the south and then southeastward following the steering current in the middle troposphere. Based on these analyses, the physical model of the sudden record heavy rainfall has been proposed and a comparison between the heavy rainfall in this case and one in China has been conducted. | Ghulam RASUL Qamar-uz-Zaman CHAUDHRY 赵思雄 曾庆存 | 2004 | Advances in Atmospheric Sciences2004，21，6： | 0 |
