Meeting goals


Understanding interdecadal variability of the climate system is a prerequisite for attribution of present and future changes under anthropogenic forcing.  The global monsoon systems (Asian-Australian; West African; American Monsoons) exhibit important decadal variations with potential large socio-economic impacts, but there is little consensus on the character of this variability.  Recent studies have highlighted interdecadal variability in:

  • The various regional monsoons;
  • Features embedded in the monsoon, such as tropical cyclones and monsoon depressions;
  • The strength of monsoon teleconnections, impacting the prospect for seasonal prediction.

Major objectives are (a) review evidence of monsoon interdecadal variability collectively and regionally; (b) discuss how these variations are linked to each other and other major modes of interdecadal variability in the global oceans such as the PDO, IPO, or AMO, and to climate change; (c) examine possible mechanisms underlying these interdecadal variations, including in simulations and numerical experiments that address driving physical processes with the goal of assessing the predictability of monsoon interdecadal variations.

Sessions will last around half a day each, consisting of invited speaker(s) and a period of discussion.  The majority of scientific presentations will be made via interactive poster sessions:

  • Session 1: Monsoon decadal variability in the modern observational era (19th/20th centuries).
  • Session 2: What do palaeo-modelling and proxy data tell us about monsoon interdecadal variability?
  • Session 3: Interconnections between the regional monsoons and other modes of climate variability.
  • Session 4: Mechanisms for decadal modulation of the monsoon.
  • Session 5: Using our knowledge of decadal variability to further monsoon prediction and projection.


The workshop will provide an overview of the state of knowledge and emerging issues in monsoon interdecadal variability and promote coordinated experimental designs to test possible causes and explore predictability.  The workshop will be of potential interest to climate scientists of the tropical monsoon regions, as well as those with expertise in ENSO and multi-decadal ocean variability, the seasonal forecasting, climate impacts and PAGES communities. We hope to promote current/palaeo-climate collaborations.

We expect attendance of around 80 international scientists including graduate students and early career researchers.  Some limited funding may be available for attendees from some countries.  Please send a short (max 2 page) CV and statement explaining your interest if you wish to be considered for funding.

The call for abstracts is now open until 1 May 2012.  Please specify the main session of interest. 

For further information, to be added to the list of interested participants or send an abstract please contact Dr Andy Turner, cc Prof Bin Wang

After-conference Tour Arrangement (Optional


Yangzhou Tour (Sept. 15-16, 2012)

1. Hotel information

  Yangzhou Slender West Lake Hot Spring Resort is a four star hotel located by the picturesque Slender West Lake. The resort is equipped with elaborately designed diverse guest rooms, the Chinese-western cafeteria that can hold over 800 people, 68 shaped hot spring pools with different functions, various kinds of SPA that can relax your mind and the health management plan specially made for the gusts. Around the resort, there are abundant tourism resources---Slender West Lake, Million Flowers Garden, Daming Temple, Guanyin Mountain, Han Tomb Garden, The Window of World animals, Ge Garden and many other famous scenic spots.


2. Attractions introduction

Slender West Lake: Slender West Lake, like an ink painting unrolled in right order, wanders on the territory of Yangzhou city. The boat travels in the water and visitors travels in the picture. The drizzle is like silk. The smoke and the water combine to produce a kind of mist. The shine of the wave is very clear like the slender waist of a beauty, delicate and attractive. It is suitable to travel on water when appreciating the slender west lake. The boat is floating with the wave and the visitor can appreciate the scenery carefully, the smoke and wave, red balustrade and small bridge, shadow and scent. The dreamy and brocade-like green and blossom extends to the water of the lake, creating a lifelike picture with the sound of oaring.

He Garden: when you visit the He garden, you need to visit the both the upstairs and downstairs with a zigzag route at the low and high elevation. The 1500-meter double-way corridor is hailed as the rudiment of overpass. The window with flowers as decoration is foiled by the scenery. With the foil of the false mountain, the water and the pond complements with each other. A small town takes the sky light, cloud, bird’s chips, and flower fragrance in its arms. The romantic time flows out during the finger on the wooden corridor.

Ge Garden: the bamboo in the garden is very green. The strong branches extend the vicissitudes of 190 years and form the wandering and green scenery for you. “The mountain is very quiet in spring, and is very green in summer, and is very clear in autumn and is very dim and sleepy in winder”. The four seasons are experienced in the way. We can hardly sigh with the short life and see the “Land of Idyllic Beauty” when lifting our head. Out of the wall made of blue brick and red tile is a different world.

Mount Huangshan: Huangshan, known as 'the loveliest mountain of China', was acclaimed through art and literature during a good part of Chinese history (e.g. the Shanshui 'mountain and water' style of the mid-16th century). Today it holds the same fascination for visitors, poets, painters and photographers who come on pilgrimage to the site, which is renowned for its magnificent scenery made up of many granite peaks and rocks emerging out of a sea of clouds.


Dunxi Old Street: Lying in the center of Tunxi district, Huangshan city, Tunxi Old Street is 832 meters long and 5-8 meters wide. With hundreds of years of history contained here, the street boasts some of the best-preserved buildings in the architectural styles of the Song, Ming and Qing dynasties. A commercial street for pedestrians only, there row upon row of shops, the buildings simple but elegant. Tunxi Old Street dates since the Song Dynasty. It gradually became a distribution center for goods and materials bound for Huizhou during the Ming and Qing dynasties.
