DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

Over the past decade, Arctic Oscillation (AO) has been concerned as an important issue of climate variability during the Northern Hemisphere (NH) winter. It refers to the zonally symmetric seesaw between sea level pressure in polar and mid-latitude, and the character is usually clear in winter. However, there are few researches about the impact of AO in Asia due to the active centers of AO are mainly located near America and Europe region. And its formation mechanism is still not clear.
We use stream function budget and wave activity flux method to investigate the wave character and formation mechanism of AO. The results are shown in the following. (1)According to stream function budget analysis result, the major dynamical process in changing general circulation structure is vorticity stretching effect, and we find a new active center at mid-latitude eastern Pacific region (150oW ~ 120oW, 30oN ~ 50oN), which hasn’t been mentioned yet. (2)After analyzing wave activity flux, we noticed that the mid-latitude eastern Pacific is exactly where the wave energy enhanced at first, the energy signal of AO is originated from this region, not come from North Atlantic. The convergence anomaly in lower troposphere is enhanced due to the positive sea surface temperature anomaly on eastern Pacific, and is coordinated with the divergence anomaly in upper troposphere. It induces strong convection, then brings potential heat to upper troposphere to excite wave energy. The general circulation structure changes during the east propagation of wave energy, therefore the energy signal of AO is the response of thermal forcing. The wave energy provides a suitable environment for disturbance development, and interacts with local weather systems, so the weather system could enhance to stimulate more energy.
