利用NCAR/NCEP、NCEP/NOE再分析资料和国家卫星气象中心下发的0.1°×0.1°的FY-2卫星资料对广汉机场一次雷暴天气过程进行分析。结果表明此次过程是由冷锋和副高共同影响产生;卫星产品如云导风(AWV)、由云分析出的湿度廓线(HPF)和云顶亮温(TBB)在雷暴发生的短时和临近预报中有较好的指导作用。
Based on the NCAR / NCEP, NCEP / NOE reanalysis data and the 0.1 ° × 0.1 ° FY-2 satellite data released by the National Satellite Meteorological Center, a thunderstorm weather course at Guanghan Airport was analyzed. The results show that this process is caused by both the cold front and the subtropical high. The satellite products such as AWV, HPF and TBB, Near the forecast has a good guiding role.
