| 摘要: |
| 普查分析广西1961~2004年大范围高温天气有关气象资料,总结广西大范围高温天气的气候特征、主要影响系统及其物理机制和环流形势,并分析相关的典型高温天气过程。结合作者实践经验,得出利用副热带高压、热带气旋和西南暖低压这三个影响系统预报广西高温天气的关键指标为:(1)副热带高压:在20~30°N,105~120°E之间,共有12个点,至少有9个点H≥588,其余的则要H≥586;(2)热带气旋:H25130、H25125、H25120、H20120中至少有1站≤582;(3)西南暖低压:P25105、P25110、P30105有一站≤1000或两站≤1003;(4)850hPa有暖中心配合:T25105+T25110≥40或T25105+T25110+T30110≥57。 |

| Abstract: |
| The typical large-scale high temperature processes,climatic characteristics,main influential systems and circulation situation are discussed by using the temperature data of 89 meteorological stations in the period of 1961 to 2004 over Guangxi.Based on the data analysis and experience,the subtropical high,tropical cyclone and southwest warm low are chosen as indicators to forecast the high temperature processes in Guangxi.For the subtropical high,20~30°N,105~120°E,there are 12 points in which nine points are at H ≥ 588,the rest at H ≥ 586.For tropical cyclone,there are four points of H25130、H25125、H25120、H20120 in which at least one point is at ≤ 582.For southwest warm low,there are three points of P25105、P25110、P30105 in which there is one point at ≤ 1000 or two points at ≤ 1003.For 850hPa with warm centre,T25105+T25110 ≥ 40 or T25105+T25110+T30110 ≥ 57. |
