2005年6月宁夏石嘴山地区高温天气及异常分析

为了提高对高温天气的预报能力和水平，对宁夏石嘴山市2005年6月出现的持续性晴热高温天气，从环流形势，大气环流异常，全球气候变暖，副热带高压位置、强度，极涡位置，台风活动情况和数值预报产品等方面进行了综合分析，总结出了该次高温天气的环流特点和成因．结果表明，大气环流异常导致大陆暖高压带停滞不动且长时间稳定控制石嘴山地区是该次高温天气出现的重要因素；结合该地区情况提出了其预报思路．

Analysis of high temperature and abnormal weather in June 2005 Shizuishan of Ningxia

In order to improve the forecast of high temperature effectively,it was analyzed the weather with circumfluence position,anomaly circulation,the global climate warming,variation in intensity and location of subtropical high pressure band and location of polar vortex and typhoon,the numerical weather prediction that on June 2005,a lasting clear and rare high temperature occurred in Shizuishan of Ningxia,and then,the paper summarizes the character and causation of high temperature weather.It plays an important role in high temperature weather of Shizuishan that the warm high pressure band of stagnation abnormal circulation which controls Shizuishan area steadily for a long time.Finally,the thought of high temperature forecast is given.
