冷涡背景下MCS的统计分析 总被引：3，自引：2，他引：1
文章首先给出冷涡的定义,根据冷涡的定义识别出冷涡,2005—2011年4—9月7年共识别出60个冷涡,主要形成在蒙古和我国的东北地区。然后根据中尺度对流系统(MCS)的标准按尺度大小将MCS分类为α中尺度对流系统（MαCS）和β中尺度对流系统（MβCS）,又按MCS的形状将MαCS分类为中尺度对流复合体（MCC）和持续拉长状对流系统（PECS）,MβCS分类为β中尺度对流复合体（MβCC）和β中尺度持续拉长状对流系统（MβECS）。利用FY 2C(2005—2009年)和FY 2E（2010—2011年）的TBB资料对60个冷涡背景下的MCS进行识别并对其时空分布特征及其与冷涡的关系进行统计分析。结果表明：(1) 60个冷涡过程识别出61个MCS,MCS通常产生在我国东北和华北,MCC和PECS生成较分散;MβCC主要集中在华北和东北地区;MβECS主要集中在东北地区。(2) 6月生成的MCS最多,有16个,9月最少。MCS大多形成于当地的下午和晚上,此时对流发展旺盛,有利于中尺度对流系统的产生,到了夜间MCS发展成熟,至凌晨—日出时分消散。(3) 冷涡背景下的MCS的移动路径多数是从西向东偏北的,其生成后主要向东移动,这和我国中纬度西风带天气系统的移动路径基本一致,但由于受冷涡等天气系统的影响,会出现不同的移动方向。位于冷涡东侧且距离冷涡中心距离较近的MCS有向东偏北方向移动的趋势;位于冷涡南侧且距离中心较远的MCS有向东偏南方向移动的趋势。(4) 冷涡背景下的MCS主要产生在冷涡的发展阶段,成熟和消散阶段相对较少。(5) 冷涡背景下的MCS主要形成在冷涡的东南部,西南部也有一小部分。(6) MβCS系统发展较MαCS系统快,持续的时间也较MαCS短。 相似文献

目前较详细的中尺度对流系统(MCS)分类普查研究还较少.文章使用我国风云2号地球静止卫星红外数字图像资料分类普查了2008-2010年夏季(6-8月)我国中东部地区(27°～40°N、110°～124°E)中尺度对流系统时空特征.根据尺度大小将MCS分类为α中尺度对流系统(MαCS)和β中尺度对流系统(MβCS),又根据MCS形状将MαCS分类为中尺度对流复合体(MCC)和持续拉长状对流系统(PECS),MβCS分类为β中尺度对流复合体(MβCCS)和β尺度持续拉长状对流系统(MβECS).3年夏季共识别了208个MCS,其中68个MαCS和140个MβCS,拉长状系统居多,占MCS总数79.3％,这表明拉长状的MCS是该区域夏季的主要对流系统.从月际变化来看,7月最多,8月次之,6月最少.大部分MCS移动路径自西向东,少数为自南向北或自北向南的移动路径,自东向西的路径极少.MCS形成高峰时段为9-10 UTC(世界时),成熟高峰时段为10-11 UTC,消散高峰时段为12-13 UTC,生命史约为6.5h.MαCS从形成到成熟需3～4 h,成熟至消散需4～5 h;MβCS发展和减弱时间相当,为2～3 h. 相似文献

东北地区一次短时大暴雨β中尺度对流系统分析 总被引：10，自引：1，他引：9
为了探寻东北短历时暴雨的预报线索,利用自动站、卫星和常规气象观测资料相结合的方法,研究2006年8月10日最大1 h雨量达到90.8 mm(泰来,其中,后半小时降水82 mm)的东北中西部百年一遇短历时特大暴雨中尺度对流系统(MCS)发展过程,及其发生的天气尺度背景和中尺度环境与触发机制.通过红外卫星云图和高分辨率的可见光云图,分析MCS如何从一个γ中尺度发展为α中尺度对流复合体(MCC)的过程.分析表明,与6个市(县)半小时雨量超过33 mm相关联的MβCS分别发生在2个阶段,第1阶段在MCC形成之前,MβCS主要向东移动(最后合并成MCC),第2阶段,在MCC成熟阶段.MpCS出现在MCC的西南边缘,而且最强短历时暴雨就发生在这里.从分辨率更高的可见光云图上可以发现,有北、西两条积云线,它们交汇的地方MβCS强烈发展并产生暴雨.分析MCS加强和产生暴雨的原因表明:(1)暴雨发生前夕暴雨区域具有高温、高湿和对流性不稳定层结,并存在明显的对流有效位能增加、抬升凝结高度及自由对流高度降低的现象,有利于暴雨发生;(2)β中尺度云团之间的合并,使MCS迅速发展,产生暴雨;(3)北、西两条积云线分别与地面风场中的两条辐合线相对应,在它们交汇处的较强辐合导致β中尺度云团强烈发展产生暴雨.分析MCS在MCC西南方向传播的原因表明,两条辐合线的移动方向和速度决定了暴雨MCS的传播方向.另外,偏北气流的出现和新老云团的新陈代谢过程是触发暴雨的关键因素.上述分析结果也为短历时暴雨的预报提供了有用的线索. 相似文献

The spatial and temporal variations of daily maximum temperature(Tmax), daily minimum temperature(Tmin), daily maximum precipitation(Pmax) and daily maximum wind speed(WSmax) were examined in China using Mann-Kendall test and linear regression method. The results indicated that for China as a whole, Tmax, Tmin and Pmax had significant increasing trends at rates of 0.15℃ per decade, 0.45℃ per decade and 0.58 mm per decade,respectively, while WSmax had decreased significantly at 1.18 m·s~(-1) per decade during 1959—2014. In all regions of China, Tmin increased and WSmax decreased significantly. Spatially, Tmax increased significantly at most of the stations in South China(SC), northwestern North China(NC), northeastern Northeast China(NEC), eastern Northwest China(NWC) and eastern Southwest China(SWC), and the increasing trends were significant in NC, SC, NWC and SWC on the regional average. Tmin increased significantly at most of the stations in China, with notable increase in NEC, northern and southeastern NC and northwestern and eastern NWC. Pmax showed no significant trend at most of the stations in China, and on the regional average it decreased significantly in NC but increased in SC, NWC and the mid-lower Yangtze River valley(YR). WSmax decreased significantly at the vast majority of stations in China, with remarkable decrease in northern NC, northern and central YR, central and southern SC and in parts of central NEC and western NWC. With global climate change and rapidly economic development, China has become more vulnerable to climatic extremes and meteorological disasters, so more strategies of mitigation and/or adaptation of climatic extremes,such as environmentally-friendly and low-cost energy production systems and the enhancement of engineering defense measures are necessary for government and social publics. 相似文献

正While China’s Air Pollution Prevention and Control Action Plan on particulate matter since 2013 has reduced sulfate significantly, aerosol ammonium nitrate remains high in East China. As the high nitrate abundances are strongly linked with ammonia, reducing ammonia emissions is becoming increasingly important to improve the air quality of China. Although satellite data provide evidence of substantial increases in atmospheric ammonia concentrations over major agricultural regions, long-term surface observation of ammonia concentrations are sparse.

The moving-window correlation analysis was applied to investigate the relationship between autumn Indian Ocean Dipole (IOD) events and the synchronous autumn precipitation in Huaxi region, based on the daily precipitation, sea surface temperature (SST) and atmospheric circulation data from 1960 to 2012. The correlation curves of IOD and the early modulation of Huaxi region’s autumn precipitation indicated a mutational site appeared in the 1970s. During 1960 to 1979, when the IOD was in positive phase in autumn, the circulations changed from a “W” shape to an ”M” shape at 500 hPa in Asia middle-high latitude region. Cold flux got into the Sichuan province with Northwest flow, the positive anomaly of the water vapor flux transported from Western Pacific to Huaxi region strengthened, caused precipitation increase in east Huaxi region. During 1980 to 1999, when the IOD in autumn was positive phase, the atmospheric circulation presented a “W” shape at 500 hPa, the positive anomaly of the water vapor flux transported from Bay of Bengal to Huaxi region strengthened, caused precipitation ascend in west Huaxi region. In summary, the Indian Ocean changed from cold phase to warm phase since the 1970s, caused the instability of the inter-annual relationship between the IOD and the autumn rainfall in Huaxi region. 相似文献

Connections between the Eurasian teleconnection and concurrent variation of upper-level jets over East Asia 总被引：3，自引：0，他引：3
The variation of the East Asian jet stream(EAJS) associated with the Eurasian(EU) teleconnection pattern is investigated using 60-yr NCEP–NCAR daily reanalysis data over the period 1951–2010. The EAJS consists of three components: the polar front jet(PFJ); the plateau subtropical jet(PSJ); and the ocean subtropical jet(OSJ). Of these three jets over East Asia,the EU pattern exhibits a significant influence on the PFJ and OSJ. There is a simultaneous negative correlation between the EU pattern and the PFJ. A significant positive correlation is found between the EU pattern and the OSJ when the EU pattern leads the OSJ by about 5 days. There is no obvious correlation between the EU pattern and the PSJ. The positive EU phase is accompanied by a weakened and poleward-shifted PFJ, which coincides with an intensified OSJ. A possible mechanism for the variation of the EAJS during different EU phases is explored via analyzing the effects of 10-day high-and low-frequency eddy forcing. The zonal wind tendency due to high-frequency eddy forcing contributes to the simultaneous negative correlation between the EU pattern and the PFJ, as well as the northward/southward shift of the PFJ. High- and low-frequency eddy forcing are both responsible for the positive correlation between the EU pattern and the OSJ, but only high-frequency eddy forcing contributes to the lagged variation of the OSJ relative to the EU pattern. The negative correlation between the EU pattern and winter temperature and precipitation anomalies in China is maintained only when the PFJ and OSJ are out of phase with each other. Thus, the EAJS plays an important role in transmitting the EU signal to winter temperature and precipitation anomalies in China. 相似文献

<p>PARTITION OF SEASON BASED ON MULTIELEMENTS AND THE DECADAL CHANGE OF SEASON DURATION IN CHINA</p>
<p>Using the multielements similarity measurement method and 1950–C2017 NCEP/NCAR gridded daily reanalysis datasets, we analyzed season duration in China during 1950–C2016, and we defined the element with maximum absolute sensitivity as the key impact element at each point using the sensitivity analysis method. The decadal change of season duration and its key impact element before and after 1980 were studied. The results indicated obvious meridional and zonal differences in the distribution of season duration for the 67-year average, and that the key impact element has the same distribution characteristics as season duration. In addition, complementary relationships were found between the durations of spring and summer, autumn and winter, and the cold and warm seasons. Of those, the complementary relationship between the durations of spring and summer was strongest and the regions of complementarity were numerous. The complementary regions of autumn and winter durations were found mainly in western China. In the cold and warm seasons, the complementary regions were widespread and the complementary relationship was generally weak. Comparison of the periods before and after 1980 revealed an east–Cwest difference in the interdecadal variation of season duration. Interdecadal variation in spring and summer was found concentrated in northern and western regions, while that in autumn and winter was concentrated in the western region. Areas of significant interdecadal variation of the key elements were found concentrated in northern and western regions, corresponding well with the areas of significant interdecadal variation of season duration.</p> 相似文献

By using the gauged rainfall in 160 stations within mainland China and the NCEP/NCAR reanalysis data, the impacts of anomalous SST in Kuroshio and its extension on precipitation in Northeast China were investigated. The results show that a difference in the meridional circulation such as the East Asia/Pacific teleconnection pattern(EAP)may be responsible for the difference in rainfall between 1998 and 2010. In comparison with 1998, the anomalous meridional circulation pattern in 2010 shifted northeastward, and then the western subtropical high, the mid-latitudinal trough and the northeastern Asia blocking high also shifted northeastward, causing intensified convergence of the cold and warm air masses at the southern region and thus more rainfall in the southwestern region and less in the northwestern region. In 1998, the anomalous cyclone, one component of the meridional pattern, located at the Songhuajiang-Nengjiang River basin, resulted in more rainfall in the majority of the area. The results of observation and the model show that the difference in SSTA in Kuroshio and its extension under the background of different El Ni觡o events is the key point:(1) The anomalous warmth moved westward from the mid-Pacific to the east of the Philippine Sea during the central event, which led the heat resources shifting to the northeast in 2010; subsequently, a shift occurred to the north of the anomalous ascent and decent, followed by a warm SSTA in the region of Kuroshio's extension in 2010 and Kuroshio in 1998.(2) The warm SSTA in the Kuroshio extension causing the Rossby wave activity flux strengthened in 2010, and then the westerly jet shifted northward and extended eastward. A warm SSTA in Kuroshio and cold SSTA in its extension in 1998 caused the westerly jet to shift southward and weaken. As a result,the anomalous anticyclone and cyclone shifted northward in 2010, and the blocking high also shifted northward. 相似文献

Understanding potential future influence of environmental, economic, and social drivers on land-use and sustainability is critical for guiding strategic decisions that can help nations adapt to change, anticipate opportunities, and cope with surprises. Using the Land-Use Trade-Offs (LUTO) model, we undertook a comprehensive, detailed, integrated, and quantitative scenario analysis of land-use and sustainability for Australia’s agricultural land from 2013–2050, under interacting global change and domestic policies, and considering key uncertainties. We assessed land use competition between multiple land-uses and assessed the sustainability of economic returns and ecosystem services at high spatial (1.1 km grid cells) and temporal (annual) resolution. We found substantial potential for land-use transition from agriculture to carbon plantings, environmental plantings, and biofuels cropping under certain scenarios, with impacts on the sustainability of economic returns and ecosystem services including food/fibre production, emissions abatement, water resource use, biodiversity services, and energy production. However, the type, magnitude, timing, and location of land-use responses and their impacts were highly dependent on scenario parameter assumptions including global outlook and emissions abatement effort, domestic land-use policy settings, land-use change adoption behaviour, productivity growth, and capacity constraints. With strong global abatement incentives complemented by biodiversity-focussed domestic land-use policy, land-use responses can substantially increase and diversify economic returns to land and produce a much wider range of ecosystem services such as emissions abatement, biodiversity, and energy, without major impacts on agricultural production. However, better governance is needed for managing potentially significant water resource impacts. The results have wide-ranging implications for land-use and sustainability policy and governance at global and domestic scales and can inform strategic thinking and decision-making about land-use and sustainability in Australia. A comprehensive and freely available 26 GB data pack (http://doi.org/10.4225/08/5604A2E8A00CC) provides a unique resource for further research. As similarly nuanced transformational change is also possible elsewhere, our template for comprehensive, integrated, quantitative, and high resolution scenario analysis can support other nations in strategic thinking and decision-making to prepare for an uncertain future. 相似文献
