1On the Spatio-Temporal Variations of the Tropopause Height over India and Indian Summer Monsoon Activity显示文摘The spatio-temporal variation of the tropopause height (TH) over the Indian region (5°N-35°N, 70°E-95°E) has been studied using monthly mean TH data, for 22-year period, 1965 to 1986. The study revealed that the stations south of 20° showed maximum TH in April / May and minimum in September. This variation in TH has been attributed to the corresponding variation of average sea surface temperature (SST) over ± 20° latitudinal belt over Indian Ocean, Arabian Sea and Bay of Bengal. Further the stations north of 20°N showed maximum in June and minimum in October/ November. This maximum in TH has primarily been attributed to the increased insolation and convection. Furthermore it is noticed that the anomaly of TH moved northwards during the period April to July.The interannual variability of the Indian Summer Monsoon Activity (ISMA) has been studied in relation to all India mean TH (at 12 GMT) for six months April through September. The composites of mean TH for good and bad monsoon years showedJ.R.Kulkarni R.K.Verma 1993Advances in Atmospheric Sciences1993,10,4:1
2Global Annual Mean Surface Air Temperature Anomalies and Their Link with Indian Summer Monsoon Failures显示文摘Analysis of the global mean annual temperature anomalies based on land and marine data for the last 88 years (1901-1988) of this century has been carried out with a view to find any relationship with failures in Indian summer monsoon rainfall. On the climatological scale (i.e. 30 years) it has been noticed that there is an abnormal increase in the frequency of drought years during epochs of global warming and cooling, while it is considerably less when global temperatures are near normal. Results are unchanged even when the data are filtered out for ENSO (El-Nino Southern Oscillation) effect.It has also been noticed that during warm and cold epochs in global temperatures the amount of summer monsoon rainfall decreases as compared to the rainfall during a normal temperature epoch.S.S.Dugam S.B.Kakade R.K.Verma 1990Advances in Atmospheric Sciences1990,7,2:0
3应用田口设计法探讨影响地毯压缩性能的因素显示文摘为满足客户对产品高品质与快速可靠的交付要求,新的加工制造技术正飞速发展,这也促进了新产品的开发与制造工艺的改进。地毯主要可分为机制地毯和手工地毯两类,机制地毯有时也称动力制造地毯。各种机制地毯通常可通过针刺与黏合技术制备。R.K.Verma A.Agarwal P.Srivastava S.K.Giri 刘书惠(译) 孟粉叶(校) 2018国际纺织导报2018,46,9:0
4聚酰胺地毯废料在聚合物复合材料开发中的应用:压缩行为研究显示文摘重点介绍了由聚酰胺(PA)地毯废料制成的聚合物复合材料的压缩行为。该复合材料是使用改进的真空辅助树脂传递模塑(VARTM)方法开发的。所制备的PA地毯废料复合材料样品的测试结果表明,该样品可承受约2 900 N的压缩载荷,证实了其在结构应用中的可行性和应用潜力。这项工作旨在最大限度地降低由传统的地毯废物处理法,如填埋、焚烧、分解等造成的环境危害。B.Jaiswal S.Mishra R.K.Verma 吴风帆(译) 孟粉叶(校) 2022国际纺织导报2022,50,11:0
