| Participating countries |
Participants from the following countries were funded: Australia, Fiji,
French Polynesia, Indonesia, Japan, Malaysia, New Caledonia, New Zealand,
Papua New Guinea, P. R. China, Philippines, Republic of Korea, Thailand,
Viet Nam.

A participant from each of the listed countries (except Australia) was
funded by APN. Owing to travel problems, the invited participant
from Samoa was unable to attend at the last minute. A further ten
participants from BMRC, the National Climate Centre (NCC), and CSIRO Atmospheric
Research in Australia were self-funded. There were two participants from
New Zealand, and one of them was also self-funded. Malcolm Haylock, the
consultant who has managed the data issues for the previous workshops,
is now working in UK. He was funded to return to Melbourne to support
this workshop. Lisa Alexander, a scientist with the UK Hadley Centre
and closely involved with climate extremes research, was on holiday in
Australia in December, and she agreed to participate in the workshop.
Brief introduction and background
The importance of monitoring and analysing climate extremes has been
highlighted by the last three assessment reports of the IPCC. Over the
last few years, there has been increased research in developed countries
aimed at improving the analysis of climate extremes. However, the
national and regional trends in climate extremes are of interest to all
countries, and this APN project aims first to enhance the capacity of participating
countries to monitor and analyse their own data and secondly to enable
national trends to be put into a regional context. The current phase
of the project included the fourth in a series of Workshops on Climate
Extremes in Southeast Asia and the South Pacific which was held at the
Bureau of Meteorology, Melbourne, Australia, 11-13 December 2002.
Outline of activities conducted
The main activity in the first year was a three-day workshop in Melbourne
in April 2001, involving representatives of seventeen countries.
Following the workshop, a web page for the APN Network for Climate Extremes
was established <http://www.bom.gov.au/bmrc/csr/apn>
containing documents and software from the first three workshops, as well
as some results of the analyses.
The key activity for the current year was a workshop in Melbourne in
December 2002. The focus of the meeting was on the collection and
archiving of meta-data for climate extremes and on data rescue and rehabilitation.
Meta-data, or "data about the data," are vital to the process of rehabilitating
climate records, where instrumentation has changed, sites moved, or objects
(like trees or buildings) near the observing sites have changed.
Many countries have only paper records of their climate data, and so these
data and the accompanying meta-data must be transferred to computer storage
systems. Following the workshop, it is planned to update the APN
Network for Climate Extremes web page to include the results of the workshop.
Outcomes and products
The products from the project at the end of the second year are as
follows:
- Each participant received a CD-ROM containing new or updated software
for quality control, the calculation of climate extreme indices, and meta-data
entry. The CD-ROM also contained all presentations from participants,
including lectures and country reports. Thus the CD-ROM updates and
extends the material provided at the previous workshop, and so provides
a basis for further improvement of data analysis in each participating
country;
- Each participant has commenced the process of establishing a meta-data
archive, and documenting data they have yet to digitise;
- Updated analysis of national data on climate extremes, carried out
by individual participants;
- Updated regional analysis of climate extremes, providing a regional
context for national analyses;
- A report on the workshop will be prepared for the APN Newsletter;
- The web site will be updated to include the results of the current
workshop; and
- A journal paper, co-authored by all participants, will be finalised
and submitted for publication.
The outcomes of the project include:
- Maintenance of the APN profile in the international science community;
- Strengthened regional links through collaborative work across many
countries;
- Enhanced understanding of climate in the Asia Pacific region; and
- Enhanced understanding of the requirements for collection and archiving
of climate data and associated meta-data by participants.
Future directions and follow-up work
It is proposed that a workshop will be held in about March 2004 to
maintain the network of scientists focussed on the analysis of climate
extremes, to provide updated software for the analysis of climate extremes,
and to update the regional analyses of climate extremes. The highest priority
activity for the future continues to be seen by the participants as enhanced
work on the digitisation and analysis of historical pressure, rainfall
and temperature data.
