Main meteorological factors for disaster caused by landfalling tropical cyclones in China are analyzed based on samples formed during 1980-2004. It is shown that the degree of disaster has strong relation with precipitation, gale, and landfalling intensity and position point of typhoon, et al.
利用1980-2004年的台风基本资料,对我国台风(包括热带气旋、热带风暴、强热带风暴、台风、强台风和超强台风)灾害的成因进行了初步分析,结果表明:台风引起的大风和降水以及登陆台风的强度和登陆点位置等都是我国台风致灾的重要因素。

The result shows that the strong sandstorm mainly appeared in Feb. to Jun., the strong sandstorm was caused mainly by momentum downloading gale of strong northwest air current before the high-pressure ridge in Jan. to Mar., the strong sandstorm was caused mainly by frontal area wind of cold air moving to southeast with ground cold front transiting.
发现强沙尘暴主要出现在2~6月,1~3月出现的强沙尘暴主要为高压脊前强西北气流动量下传风所致;4~7月出现的强沙尘暴主要为冷空气东移南下伴随地面冷锋过境锋面大风所致。

The result showed that the strong storm followed by mesoscale squall line was primary cause of strong sandstorm producing, steps and ladders short wave trough of 500 hPa was great criterion triggering system for the mesoscale squall line producing, the essential dynamic condition was provided by distortion field and the mesoscale low pressure of 700 hPa for the strong sandstorm forming and maintaining in mid-west of Hexi Corridor, the deep vertical circulation development condition was basic power that urged squall line to occur and sand dust to curl up, which was provided for the deep convection development by superimposition of lifting movement before ground cold front and ascendant current of secondary circulation in upper air jet entrance region, temperature and the barometric gradient around the cold front was enlarged by enhancement of ground thermal low and temperature diurnalvariation of afternoon, by which essential thermal energy unstable condition was provided for the gale and strong sandstorm eruption, the strong sandstorm appeared in downstream of -200 m^2s^(-2) center of vertical helicity, the vertical helicity had good instruction significance for development of squall line and landing region of sandstorm, the mesoscale squall line occurred in unstable stratification, basic condition of potential energy transforming as kinetic energy was provided by strong unstable stratification for the strong sandstorm forming and developing.
结果表明:中尺度飑线所伴随的强风暴是产生强沙尘暴的主要原因;500 hPa阶梯短波槽是中尺度飑线产生的大尺度触发系统,河西走廊中西部700 hp变形场、中尺度低压为强沙尘暴形成和维持提供了必要的动力条件;地面冷锋前上升运动与高空急流入口区次级环流的上升气流的叠加,为深对流发展提供了深厚的垂直环流发展条件,是促使飑线发生和沙尘卷起的基本动力;地面热低压的加强和午后气温的日变化加大了冷锋前后的温度和气压梯度,为大风、强沙尘暴爆发提供了必要的热力不稳定条件;强沙尘暴出现在垂直螺旋度为-200平方公尺/s^2中心的下游,垂直螺旋度对飑线的发展和沙尘暴的落区具有较好的指示意义;中尺度飑线发生在不稳定层结内,较强的不稳定层结为强沙尘暴形成、发展提供了位能转化为动能的基本条件。

By using global reanalysis data from NCEP/NCAR,the durative of a floating dust over Beijing during 7-10 in April of 2006 was analyzed.It was found that the impact systems of the floating dust weather were West Siberia cold eddy,Okhotsk warm high and Tibetan Plateau high ridge at the level of 500 hPa;the dry-cold air at the level of 700 hPa transferred to Beijing ceaselessly,and the cold advection and baroclinic instability were strong,the gale and dust storm occurred in the strong cold advection area;the weak instability stratification in surface layer and mid-low level in the south of North China resulted in weak ascending air flow,then transported dust particles to Beijing depending on the easterly wind in front of the surface low pressure.
文章摘要:使用NCEP/NCAR再分析资料对2006年4月7-11日北京浮尘天气过程的持续性进行分析,指出此次浮尘天气过程主要受500 hPa西西伯利亚冷涡、鄂霍次克海暖高压以及青藏高原高压脊影响;700 hPa有干冷空气不断向北京地区输送,冷平流和斜压性都很强,大风和沙尘暴发生在强冷平流区域;由于华北南部地区近地面至中低层存在弱的不稳定层结,容易产生弱的上升运动。
