摘要
利用ARPS模式对南京周围地区的一次大气波导过程进行了数值模拟,通过对南京站初始时刻、6 h和14 h的模拟结果分析表明:同化探空资料的初始场较NCEP资料更接近实况,初始场对预报结果的影响具有一定的持续性,且同化了探空资料的初始场的模拟结果比未同化探空资料的初始场的模拟结果较接近于真实大气状况;同化多个测站探空资料的数值模拟表明ARPS模式对大气波导具有一定的预报能力。
ARPS are used to simulate the atmospheric duct of Nanjing in this paper. After analyzing the initial fields as well as the 6 h and 14 h simulation results, we found these results：at the beginning time, the initial fields which assimilated the sounding data are closer to the atmospheric environment than the ones which only used the NCEP data. The influence induced by initial fields on forecasting results can persist for a definite time. In short, the simulation results show that the initial fields which assimilated the soundings data are closer to the environment.
