南海季风试验期间海面低层大气过程的初步数值模拟试验

采用一维高分辨率大气边界层模式(OSUPBL),模拟了南海海面低层大气,得到高分辨率的海面低层大气的各种气象要素及界面通量和能量平衡关系,并将模拟结果和南海季风试验(SCSMEX)观测结果和日本气象厅(JMA)再分析资料进行对比分析.结果指出,OSUPBL模式模拟得到的海面大气边界层的风速、温、湿垂直廓线,大气边界层高度以及海表面短波辐射、长波辐射、感热、潜热通量、净辐射和海面热收支等与实际观测结果基本一致.

Preliminary numerical simulations of marine lower atmospheric processes over South China Sea during the SCSMEX

In context of 1-D high resolution atmosphere boundary layer model,OSUPBL,this article numerically simulates the marine lower at mospheric processes over the South China Sea during the South China Sea monsoon experiment(SCSMEX) in 1998.The reanalysis data by the Meteorological Research Institute,Japan Meteorological A gency(JM A) is used to init ialize the model.The model out puts were compared against the in situ observation and the reanalysis data by the Meteorological Research Institute,JMA.The results show that,OSUP BL out puts of vertical profile of wind speed,temperature,humidity,and the simulation result of at mosphere boundary layer height,and the short-wave radiation,long-wave radiation,sensible heat flux,latent heat flux,net radiation flux,the netheat flux at sea surface are basically consistent with in situ measurements.
