摘要

利用NCEP/NCAR月平均高度场再分析资料,分别提取季节内和年际以上振荡的基本特征和形式,运用信息传输理论分析这两种振荡信号的信息在低纬度与中高纬度间的传输.发现季节内振荡信号信息损失率较年际以上的偏大,且在特定地区这两种振荡信号的信息具有反向传输的特征;空间传输的水平分布上,两种振荡信号均表现为纬向上低纬度信息损失率大且海陆分布差异显著;空间传输的垂直分布上,年际以上振荡信号的低纬度高空信息损失率较大,中高纬度从对流层至平流层底信息损失率都较小,而季节内振荡信号则是低空信息损失率大,高空信息损失率小.

Abstract

Basic characteristics and form of intra-seasonal and over inter-annual variations were extracted through filtering using the reanalysis data of monthly geopotential height from NCEP/NCAR. Then information theory was applied to the filtered data to analyze the communication among the intra-systems between the low and mid-high latitudes. The results were found that the information loss rate of intra-seasonal oscillation signal is higher than that of over inter-annual signal, and the directions of two signals’ communication are opposite in particular regions. The information loss rate at low latitudes is higher than that at mid-high latitudes for both time scale signals, and it is distinct between the lands and the oceans in meridional average. With respect to the altitudes, the information loss rate of over inter-annual oscillation signal at low latitudes is rather high, but it is low at mid-high latitudes over all troposphere and bottom of stratosphere. For the intra-seasonal oscillation signal, the information loss rate is high at low altitude but low at high altitude. The study of communication between the low latitude and mid-high latitude of the circulation system on the two time scales provides a new way to understand the predictability and interaction of different parts in the climate system.
