Abstract:
The three model fields of Atlantic-Europe circulation pattern W,C or E at 500hPa are obtained from historical data,and W,C or E circulation pattern for any day can be determined according to the minimum of Euc-distance between the given field and the model fields. Additionally,the points that minimum height value is located at are found for all parallels in the given region and smooth mean longitude and mean height for those points can be regarded as the position and intensity of the East Asia trough. This work will make the evaluation of physical parameter of the general circulation more objective and automatic.
