| 1. | Intensity of extreme precipitation is decreased very obvious in central area of north - east china and biejing area 极端降水强度减少非常显著的地区是东北中部地区和北京地区。 |
| 2. | The heaviest hourly rainfall orients to the density ice cloud portion where ice cloud become turn to be water cloud 降水强度最大的区域位于多层云附近,密实的冰云向水云过渡的冰云一侧。 |
| 3. | During the period of 4 - 5 july 2003 , a heavy rain occurred in nanjing , resulting in severe flood catastrophe “雅安天漏”是川西的一个特殊降水现象,降水强度大、尺度小,多为局地性降水。 |
| 4. | And the minimum tbb fluctuation matches well to the precipitation trend ( the lower tbb the heavier rainfall ) 强降水还与对流有关,降水强度总体上跟t _ ( bb )强度成正相关, t _ ( bb )越低降水越强。 |
| 5. | More attention is paid to using satellite passive microwave remote sensing data in estimating precipitation and many algorithms for the retrieval of rainfall have been developed 卫星被动微波遥感资料在降水估计中的应用日益受到重视,多年来已经发展了多种算法反演地面降水强度。 |
| 6. | The intensity and the anomaly of the seasonal variation of rainfall often bring flood or drought , which can do great damages to local people ' s living and the development of economy 降水强度和季节变化异常会给当地带来洪涝或者是干旱,给当地的人民生活和经济发展带来严重的损失。 |
| 7. | The brightness temperature is highly related to the density of ice hydrometeor . since the convective cloud system is tilted , and the viewing angle is oblique , the area displacement between ice hydrometeor and the surface rainfall rate makes the relation between tb and surface rainfall rate is relatively small 但亮温和地面降水强度之间的相关性较弱,这是由于该对流系统为倾斜的,冰相粒子和地面降水强度之间存在着位置上的不一致,并且观测角为倾斜的。 |
| 8. | Analyzing the physics structure of vorticity , divergence , vertical velocity , frontogenesis " function , apparent heat source and apparent moist sink etc . indicated the physics fields are favorable for the occurance of the heavy rain over changjiang - huaihe river basin where the physics values are well according to the heavy rainstorm positions ; the low level jet is closely subject to the moisture and the coupled system of the low and the upper level jetstreams induced the strongly " ascending motion ; the intensity of the frontogenesis varies with the development of the rainfall system and reacts the rainfall intensity 主要分析了这次过程中的多种物理量,包括涡度、散度、垂直速度、锋生函数、视热源、视水汽汇等,对这一暴雨过程有了比较系统的认识。结果表明:在江淮流域存在着有利于发生暴雨的物理量场配置,涡度、散度、垂直速度等物理量,与暴雨的落区都很吻合的;低空急流的产生不仅有利于水汽的输送,而且高低空急流的耦合造成了有利于强上升运动的配置;锋生强度随着降水系统的发展变化,并影响降水强度。 |
| 9. | Using the daily rainfall data of 740 stations over china and ncep daily up - ai data from 1971 to 2000 , we analyzed the average mei - yu climate field . based on the climate field and mei - yu intensity index , we confirm that the year of 1999 is a typical mei - yu . besides , the intensity of mei - yu rainfall in 1999 is the highest since we had record , so the analysis of mei - yu in 1999 can present the common characteristics of mei - yu 本文利用1971 - 2000年中国740站的日平均降水资料和ncep的日平均高空资料分析了梅雨气候场,利用梅雨的气候场及中国气象局气候诊断预测室的梅雨强度综合指数,确定了1999年是一个非常典型的梅雨年,并且1999年梅雨期间的降水强度是历史以来的最高值,因此我们对1999年梅雨进行的分析有很大的代表性。 |
| 10. | Rainfall and vertical profile of hydrometers are retrieved for land and ocean using tmi 1b11 data . the comparison of retrievals of gprof v6 . 1 and v6 . 2 with ground - based radar and gauge data on land and pr data on ocean show that the gprof - v6 algorithm can retrieve rain intensity much well and indicate vertical distribution of hydrometers mainly . as far as retrieved precipitation area , it is better for convective precipitation type than stratified precipitation type 将陆地的反演结果与地基雷达资料和地面雨量计资料进行比较,海洋的反演结果结合trmmpr的降水产品进行比较,结果表明: gprof - v6算法反演的降水产品可以较好地反映降水强度并反映降水的主要垂直结构;在落区方面,对流降水反映较好,层云降水则较差;云-辐射数据集的扩充与改进可提高反演精度。 |
