利用2004—2012年《中国气象灾害年鉴》和CFSR再分析资料,研究中国龙卷的时空分布以及三个龙卷频发区的环流背景场和环境物理量特征,并比较他们之间的区域差异。结果表明:中国龙卷多发生于春夏季,午后傍晚较多,江苏和广东等平原地区出现龙卷概率最高。龙卷临近时,"江苏及其邻近地区"位于500 hPa槽前,850 h Pa上有西南急流,造成了较强的低层垂直风切变;"广东及其邻近地区"在龙卷发生前地面对流有效位能均值达997.3 J/kg,0~1 km螺旋度均值达91 m^2/s^2,层结不稳定,动力抬升强;"东北地区"受深厚东北冷涡控制,整层水汽含量低,中低层比湿均值小于10 g/kg。通过比较环境物理量平均场的分布特征发现:螺旋度、垂直风切变、能量螺旋度指数和强龙卷参数对分析龙卷发生有很好的指示意义。"东北地区"对流有效位能和比湿均值远低于"江苏及其邻近地区"和"广东及其邻近地区",但高低空的温度直减率大、中低层的垂直风切变强,该地区也会产生龙卷。

利用FNL资料和WRF模式进行数值试验,并在此基础上研究了1324号台风Danas对1323号台风Fitow的影响特征。分析结果表明,台风Fitow登陆前、后的强度变化及其东边界与台风Danas相连的水汽输送通道的变化直接相关。台风Fitow登陆前,其水汽输入主要是由副热带高压西南侧环境场的偏东气流带来,而上游台风Danas截取了环境场输送给台风Fitow的水汽,抑制了Fitow的发展。但在台风Fitow登陆后,台风Danas环境场的水汽反过来起到转运作用,增加了Fitow的水汽收入,加剧其北侧的强降水。台风Danas以水汽通道为纽带影响台风Fitow登陆前的强度和在陆上非对称降水的分布。此外,台风Danas的北上影响了副热带高压的强度,使其东退且改变台风Fitow的引导气流,影响了Fitow的登陆位置;并在Fitow登陆后施加了偏南引导气流,令其逆时针打转。

Gastric teratoma (GT) is a seldom seen congenital abnormality. GT always occurs in children. The greater curvature and posterior wall of the stomach are the most common sites involving GT. We diagnosed a case of GT located on the inferior wall of the cardiac orifice in a 20-year-old man. To the best of our knowledge, this is the first case of GT located on the wall of the cardiac orifice in an adult in the English literature. We report this unusual case as an addition to this rare disease usually found in children. Computed tomography combined with endoscopic ultrasonography can be selected to diagnose GT.
