To solve the uncertainty of initial fields in the traditional numerical forecast, medium-range ensemble forecast experiments using the model T106L19 were made.
The forecasts by T63 model are better than that by T42 for the westerly system and subtropical high. It provides useful information for the mediumrangeforecast.
T63对西风带天气系统及副热带高压的预报也比T42好，为中期天气预报提供了信息。

An objective analogue model for mediumrange weather forecast considered synthetic evaluation by multi criterion is developed.
