Climate Teleconnection between Low and High Latitudes
Nansen-Zhu International Summer School 2008 2
The Nansen-Zhu Centre International Summer School was dedicated to the
cuttingedge scientific area of climate and climate change with a specific emphasis on
climate teleconnection between the low and high latitudes. The major thrust of the
summer school course was to present the modern concepts of climate teleconnection
and its possible mechanisms as well as to highlight the lacunas in knowledge and
topics for further research and understanding.
The school provided an opportunity for 70 M.Sc. and Ph.D. students from China,
Norway, Russia, India, France and Germany as well as young scientists aspiring to
enhance both their basic knowledge and awareness of the current developments in this
area through attending plenary lectures and participating in dedicated workshops and
poster session serving as a forum, at which all participants gave oral or poster
presentations, and participated in scientific discussions moderated by the invited
plenary session lecturers. The latter are both well acknowledged scholars from the
countries located at high and low latitudes and are capable of presenting a well
balanced vision of the current state of the art in the area in general but also in its some
specific sections. Totally more than 100 people from six countries attended the school.

The 2008 NZC International Summer School lectures and discussions covered a broad
range of climate change research issues in Arctic, sub-Arctic and the East Asia/Pacific
Ocean and the climate teleconnections between the high and the low latitudes.
At practical seminars, the participants were given the opportunity to learn about the
Earth System Model and the advanced data assimilation and the methods for
observing the Earth from the spaceborne satellite sensors.
More important, the poster sessions were organized in an interactive way between the
participated lectures and the students, raising questions from the students to the
lectures and vice versa.
Prof. Huijun Wang, director of Nansen-Zhu International Research Centre and
director-general of the Institute of Atmospheric Physics formally opened the summer
school. He welcomed the international and Chinese participants of the summer
school and addressed that the summer school received much more participants than
the two earlier Nansen-Zhu summer schools respectively in Beijing in 2004 and
Finse/Bergen (Norway) in 2006.
The first lecture was given by Prof. Huijun Wang. His talk focused on the Seasonal Climate Prediction in China with examples for predicting the precipitation and typhoon activities in China.

Nansen-Zhu International Summer School 2008 7
Prof. Tore Furevik from the University of Bergen gave the second lecture with the title of Climate Couplings between Low and High Latitudes: The Role of the Ocean Circulation on Decadal to Multidecadal Time Scales. Specifically, Prof. Furevik presented the heat transport carried by the atmosphere and the ocean.
Prof. Bingyi Wu from Chinese Academy of Meteorological Sciences, China Meteorological Administration, Beijing, China presented the lecture: Distinct Modes of the East Asian Summer Monsoon.
The lecture “Numerical simulations on the East Asian climate” was given by Prof. Tianjun Zhou from the Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing, China. He presented the multi-model simulations on the East Asian Climate including the precipitation and surface air temperature et al..
Prof. Ola M. Johannessen from the Nansen Environmental and Remote Sensing
Center, Bergen, Norway chaired the afternoon session.
Prof. Xiuqun Yang from department of atmospheric sciences, Nanjing University, Nanjing, China started the session with the talk “Northern Hemisphere Circumpolar Vortex variations during winter”.

Nansen-Zhu International Summer School 2008 8
Prof. Ola M. Johannessen gave a talk on Arctic Climate Change started with the brief introduction on the Arctic climate system and ended with the great climate challenge in the future
Dr. Kirill Khvorostovskiy from Nansen Environmental and Remote Sensing Center, Bergen, Norway gave a talk “Greenland Ice Sheet mass balance: Methods and results” and presented a nice overview on how to estimate the Greenland Ice Sheet mass balance.
An exciting part of the summer school is the self-introductions from the participated
PhD students. Each student is given two minutes to introduce himself/herself and
explain his/her PhD project including the motivation, data, method and progress or
preliminary results. The students also prepared their scientific posters presentations.

In the afternoon of Day 5, the summer school started with the brief summary by Prof.
Helge Drange from University of Bergen, Norway. He summarized the lectures
presented during the summer school as follows:
Global warming can potentially lead to
• Excessive warming of Indian Ocean and North West Pacific
• Perturbed South Asian Jet (wave train perturbation)
• Intensified NAO
• Collapse of the North Atlantic Sub-Polar Gyre
• Rapid warming in northern North Atlantic Ocean
• Weakened Atlantic THC
• Negative phase of the North Atlantic dipole SST-pattern

Nansen-Zhu International Summer School 2008 21
After the summary of the summer school, a discussion among all participants took
place, raising the following issues:
1. climate natural variability vs. anthropogenic forcing,
2. climate teleconnection, between the high and the low latitudes, is one-way
(tropical influences the high latitude region) or two-way (tropical influences
the high latitudes and vice versa)
3. possible linkage for the climate teleconnection between the high and the low
latitudes—atmosphere bridge and ocean tunnel?
4. possible climate impact of increased hydraulic cycle

Finally, the summer school was closed by Prof. Yongqi Gao representing the Prof.
Huijun Wang, director of Nansen-Zhu International Research Centre/director-general
of Institute of Atmospheric Physics. Sincere thanks to the sponsoring institutions –
Institute of Atmospheric Physics of the Chinese Academy of Sciences, Nansen
Scientific Society, University of Bergen, UNIFOB AS and National Natural Science
Foundation of China.
1. the interactive poster sessions were highly welcomed
2. the students wish the invited speakers can give long time series-lecture (for
example, three 45 minute lectures for a topic starting with basic scientific
background and gradually guiding the students into more advanced knowledge)
3. one hour lunch break is short, making Chinese students hard to concentrate on
the lectures in the afternoon.
