【摘要】 对2005年7月27～29日黑龙江省低涡暴雨天气的影响系统、物理量场、云图和雷达回波进行了诊断分析。结果表明低涡暴雨对高、中、低纬度系统的配合要求很高;低涡暴雨有比较固定的降水落区;物理量、云图、雷达回波在暴雨开始前都能有效地用于预报暴雨降水时段。更多还原

【Abstract】 Synoptic systems,physical quantity fields,cloud images and radar echoes during July 27-29 in 2005 are analyzed.Some conclusions are drawn.In order to cause low eddy rainstorm,high and middle and low latitude systems should cooperate well.Low eddy rainstorm has fixed rain area.Physical quantity fields,cloud images and radar echoes can be used to forecast rainstorm period well.更多还原
