The analysis of the SPECTRUM(Special Experiment Concerning Typhoon Recurvature and Unusual Movement) data indicates that the structure of recurving target typhoons 9015(Abe),9019(Flo) and 9020(Gene) at different stages of moving processes showed different motion features.On different time scales,temporal variations of typhoon structure and motion speed displayed different features. 相似文献

A Study on Typhoon-Induced Rainfalls over Beijing: Statistics and Case Analysis 总被引：1，自引：0，他引：1

下载免费PDF全文 Based on the Shanghai Typhoon Institute (STI) Typhoon Year Book and typhoon precipitation data,
Japan Meteorological Agency satellite TBB data, and National Centers for Environmental Prediction (NCEP)
reanalysis data, the climatic characteristics of rainfalls in Beijing associated with typhoons were analyzed
for the period 1949–2006, and two typhoon cases with remarkable differences in rainfall intensity over Beijing
were compared and diagnosed. The 58-yr statistical results show that rainfall events associated with
typhoons occurred in Beijing about once every three years during June–September. These typhoons were
mainly active in the region 20?–50?N, 109?–128?E and most of them moved northwestward while the others
turned to the northeast. The typhoon rainfall over Beijing in general sustained for 2–5 days. Typhoon
centers were usually located in the areas from Jiangxi to Anhui, the Yellow Sea, or near Beijing, when rainstorms
occurred over Beijing. Case study indicates that the 2-day torrential rainfall event that happened in
Beijing in 1984 was due to the interaction between Typhoon Freda (8407) and a westerly trough, while only
a medium-strength rainfall event occurred in Beijing in 2005 in spite of the dominating cyclonic circulation
of Typhoon Matsa (0509) directly over Beijing. It is found that both Freda and Matsa underwent extratropical
transition and possessed an asymmetric structure. The rainfall difference was caused by the fact
that Beijing was located in different convective development areas of the two typhoons. On the other hand,
the lifting conditions were different although plentiful atmospheric moisture and convective unstable energy
existed over Beijing during both events. The ascending motion of warm southerly in Beijing was stronger
and deeper and a larger vertical wind shear was associated with Typhoon Freda. However, the lifting of
water vapor was restrained by the descending motion of northerly cold airflow in Beijing under the impact of
Typhoon Matsa. Besides, it is also found that topography played an important role in the typhoon rainfall
over Beijing. 相似文献

北京地区的台风降水特征研究 总被引：7，自引：2，他引：5
采用上海台风研究所1949-2006年台风降水和台风年鉴资料、中国FY-2卫星和日本气象厅TBB资料以及NCEP再分析资料,首先分析58年台风影响北京降水的气候特征,然后对8407号台风Freda和0509号台风Matsa影响下北京两次强度差异显著的降水过程进行对比研究.结果表明:(1)台风影响北京降水年均0.33次,出现在6-9月.降水过程多为大雨以上天气过程,持续时间一般2 d,最长可达5 d.(2)影响台风的活动范围大致为(20°-50°N,109°-128°E).路径主要包括西北行和转向东北行两类,并以前者居多.北京发生暴雨时,台风中心主要出现在江西-安徽-带、黄海或北京附近.(3)Freda对北京的影响发生在台风与西风槽相互作用过程中,而Matsa的影响表现为台风低压环流直接控制北京.两个台风均受冷空气影响而变性,具有明显的非对称结构,两次过程中北京位于台风不同的对流运动发展区域是造成降水强度差异的原因之一.(4)两次台风过程中北京均具有较好的水汽条件和对流不稳定层结,但动力抬升条件差异明显.Freda影响下北京具有较强的水平风垂直切变,偏南暖湿气流上升运动深厚.而Matsa影响下北京盛行偏北气流,中低层下沉运动显著,水汽抬升受到抑制.另外,北京西北高东南低的地形也是其台风降水产生差异的原因之一.在台风东侧,地形作为偏南气流的迎风坡可加强上升运动,而在台风西侧则作为偏北气流的背风坡增强下沉运动. 相似文献

利用常规观测资料和NCEP/NCAR FNL资料对“狮子山”（1006）和“天兔”（1319）两个台风造成山东半岛秋季远距离大暴雨的特征进行了诊断分析。结果表明：1）造成两次大暴雨的天气形势和物理量特征有相似,也有差异。2）两个台风的生成源地、移动路径以及强度差别均很大,大暴雨发生在台风登陆后从广东移到广西的过程中,高空北支冷槽、台风倒槽和850 hPa切变线是造成山东半岛大暴雨的主要天气系统。3）台风东侧和副热带高压之间850 hPa偏强东南气流将东海、黄海的水汽源源不断输送到山东半岛并在此辐合;低层辐合、高层辐散和垂直上升运动均利于大暴雨的发生;大暴雨发生前大气处于不稳定大气层结;台风和中纬度系统相互作用形成两层或三层锋区的斜压性特殊结构及高空急流的增强是山东半岛秋季台风远距离大暴雨的重要特征。4）两次大暴雨过程中低空急流特征、锋区斜压性结构特征、不稳定大气层结特征存在较大差异。 相似文献

文章介绍了国家气象中心的台风路径数值预报模式（以下简称台风模式）,在不同物理过程参数化下的数值试验及其结果的诊断分析。对1992年第10号热带气旋和1996年第8号热带气旋个例的数值试验结果表明,该模式能较好地预报热带气旋移动路径和登陆地点,且考虑复杂物理过程的台风模式较简单过程的模式能更好地描述热带气旋中心附近高低层的热力状况。研究还发现,500或700 hPa湿位涡第一项MPV1负值中心的绝对值大小的变化可反映热带气旋的强弱;且850 hPa上升运动最大中心的位置对未来6～12 h热带气旋的移向有较好 相似文献
