An excellent dialogue system needs to not only generate rich and diverse logical responses but also meet the needs of users for emotional communication. However, despite much work, these two problems have not been solved. In this paper, we propose a model based on conditional variational autoencoder and dual emotion framework (CVAE‐DE) to generate ...

利用NCEP、fnl再分析资料和常规探测资料分析1981~2010年台州市局地暴雨的时空分布,并进行天气分型,对平均形势和典型个例进行了对比分析.结果表明:(1)台州局地暴雨日约占总暴雨日数的1/3,月际变化显著;局地暴雨总体上呈北多南少分布;(2)5~6月暴雨主要由西风带类造成,8~9月主要由东风带造成,7月各类暴雨均有发生.热带系统、移动低槽、南海台风是引发台州局地暴雨最多的系统.局地暴雨对于水汽输送和动力条件的要求比大暴雨要低得多.各型范围暴雨和局地暴雨在850 hPa形势场上有较明显的差异;(3)

应用自动站和NCEP 1°×1°再分析资料,对2010年7月24日发生在东南沿海的一次大暴雨过程的湿位涡场进行了诊断分析.结果表明:鞍形场低层东南风低空急流输送的暖湿气流和对流层中低层来自东北方向的冷空气相互交汇是此次大暴雨发生的触发因子,大暴雨期间暴雨区上空对流层中低层等θse线较稀疏且陡立,大气对流稳定度较低,有利于湿斜压涡度发展,大暴雨发生在600 hPa上MPV、MPV1和MPV2正负过渡带附近,MPV1下负上正垂直叠加配置是暴雨发生发展的有利形势,湿位涡在900 hPa以下具有MPV1为负 ...

为有效防治流域土壤侵蚀、维护生态安全,基于九曲水流域1982—2019年逐日降雨数据,运用小波分析、交叉小波变换等方法分析了中雨、大雨、暴雨及年降雨侵蚀力的年际变化规律,并探讨了太阳黑子、厄尔尼诺—南方涛动(ENSO)、北极涛动(AO)及太平洋年代际涛动(PDO)对它们的影响。结果表明:(1)中雨、大雨、暴雨及年降雨侵蚀力的年际变化趋势均不显著(p>0.05),其变异系数(CV)分别为0.24,0.31,0.64,0.26,均属于中等变异。(2)不同量级降雨侵蚀力的周期变化差异明显 ...

Analysis of heavy rain caused by typhoon "Fitow" in Huzhou(台风“菲特”引发湖州大暴雨的成因分析)
利用MICAPS资料和中小尺度地面自动站资料,对2013年10月6~8日台风“菲特”影响湖州地区时的大暴雨过程进行分析发现,大暴雨降水分3个阶段:台风“菲特”外围云带中的强降雨、台风本体范围及边缘的暴雨和台风“菲特”减弱后的倒槽和北上近海转向的台风“丹娜丝”外围东北气流的叠加暴雨.分析可知,东北急流带来的充沛水汽、高能高湿的能量输送、强烈的上升运动和高层辐散低层辐合等为大暴雨的发生发展提供了十分有利的环境场.天荒坪山区朝东北开口并由东北向西南多级收缩抬升的地形为暴雨的增幅创造了有利条件 ...

基于Micaps常规资料、NCEP再分析资料和中尺度自动站雨量资料,结合WRF高精度数值模拟输出的诊断物理量,研究了 2013年10月7日20:00至8日08:00发生于浙江东北部的短时大暴雨天气过程的成因.结果表明:这次大暴雨过程主要由台风“菲特”残留云系、超强台风“丹娜丝”和北方的弱冷空气共同影响产生;假相当位温及地面风场的分布很好地反映了此次大暴雨过程中的不稳定强对流及冷暖空气交汇的形势.垂直螺旋度、湿位涡的分布及演变情况与强降水的移动及强度变化有很好的对应关系 ...
