Research Institute for Global Change

The First Planning Workshop of -Eastern Indian Ocean Upwelling Research Initiative-

1. Date
1 November 2013
2. Venue
Miyoshi Memorial Hall, Yokohama Institute for Earth Sciences, JAMSTEC
3. Background

Abnormal weathers such as extreme heat wave, floods, heavy snows and intense typhoons/cyclones are increasingly affecting the socio-economic conditions all over the world. These abnormal weathers are thought to be caused by frequent occurrences of climate phenomena such as ENSO, ENSO Modoki and the Indian Ocean Dipole (IOD) under the global warming stress. New research studies have shown promises in understanding and predicting those climate phenomena. However, the scale interactions among various processes and the teleconnections need further investigations. Therefore, further research studies and information exchanges on these climate processes are important for developing early warning system and to prevent natural disasters related to climate variations.

The International Workshop "Scale Interactions in Climate Variability" is organized to discuss recent progresses in tropical and mid-latitude climate studies. The workshop will address the issues of tropical and midlatitude climate interactions and interactions among different climate scales besides addressing conventional topics related to the known climatic modes such as IOD, ENSO, ENSO Modoki, monsoon and midlatitude systems. The tropical teleconnection is a topic of interest for understanding and rectifying model errors and will be a major part of the discussions.

Several eminent international researchers are invited to speak and participate in the workshop besides the researchers from JAMSTEC. The workshop will provide a platform for JAMSTEC and other international researchers to widely introduce their new research results and to develop better understanding of our climate system.

This workshop is organized in conjunction with another climate related symposium "NEW FACES OF CLIMATE VARIABILITY" hosted by Application Laboratory, JAMSTEC to form "INTERNATIONAL SYMPOSIA ON RECENT PROGRESSES IN CLIMATE VARIABILITY STUDY".
