Through several comparing experiments, the initialization optimized by BDA scheme is found to be more reasonable than GFDL scheme and its typhoon track forecast is better.
通过试验对比发现，BDA方案优化的初始场更合理，其台风路径预报效果优于GFDL方案。
The results show that the optimal initial field produced by BDA scheme is closer to the observations and the forecast accuracy for both track and intensity is improved effectively.
结果表明，经过BDA方案优化的台风初始场更加接近实际台风的结构，有效地提高了台风路径和强度预报的准确率。
