About this Research Topic
With the advance of the observational and numerical modeling, multiple facets of high spatial-temporal frequency and its interaction with low-frequency climate variability have been revealed. For example, eddy-resolving (about 10-km horizontal resolution or finer) and subseasonal-frequency satellite observations and simulations provide great insight, including the physical understanding between fine- and large-scale interaction and the regional applicational studies and services. In addition, the recent accumulation of long-term observational studies has enabled us to detect the decadal or longer atmospheric and oceanic variability. Some examples are the long-term repeated ship observations, maintenance of TAO/TRITON arrays in the tropics and the extension of the Argo buoy network since the 2000s.
The Indo-Pacific regions are the “key regions” for climate variability of El Nino, Southern Oscillation (ENSO), Indian Ocean Dipole (IOD), and Ningaloo Nino. In these climate modes, relationships with Asian monsoon variability and oceanic response or feedback are important to understand and predict the regional climate and oceanic variation. The regional climate and oceanic prediction and its application are highly expected by social demands. Through the atmospheric and oceanic bridges (teleconnections), such tropical climate variability affects not only the tropics but also mid-latitude. For example, atmospheric Rossby wave responses (such as PNA, PJ patterns) to tropical SST anomalies cause anomalous weather (including modulation of synoptic and subseasonal variations) in the mid-latitude area. In addition, inter-basin coupling by the Indonesian throughflow (ITF) affects the heat and salinity transport between Pacific and Indian Ocean, which is important for the climate variability in the tropics. Also, recent studies have revealed inter-basin coupling between Pacific ENSO variability and Atlantic climate variability.
In this Research Topic, we would like to focus on the recent advances in the multi-scale (synoptic, subseasonal to interannual, decadal, long-trend) atmospheric and oceanic variability in the Indo-Pacific regions and their application to the environmental studies in Asia-Oceania region.
We welcome not only original research articles, but also reviews and research projects.
