We use tree-ring based hydroclimate reconstructions in Asia and North America (NA) to investigate the spatiotemporal evolution of the interdecadal teleconnections over the past 600years and their associations with coupled ocean-atmosphere patterns. The most dominant interdecadal covarying patterns are the anti-phase hydroclimate change between central Asia and central NA, i.e. the "central Asia-central NA teleconnection”, and the covarying pattern over southwestern (SW) and northeastern (NE) Asia, SW and central NA, i.e. the "SW and NE Asia-SW and central NA teleconnection”. The teleconnections are generally robust except for the cold periods during the Maunder Minimum from the fifteenth century to the end of the sixteenth century and towards the end of the Little Ice Age near the middle nineteenth century. The Asian-Pacific Oscillation (APO) related atmospheric circulations and the westerlies are found to bridge these interdecadal hydroclimate teleconnections. The coupled ocean-atmosphere patterns in the Southern Ocean can modulate the strength of APO related circulations by modulating the Asian summer monsoon and the westerlies via meridional teleconnections. In addition, the wave train from Southern Ocean to Asia may also play an important role on modulating the interdecadal teleconnections.
