Development and
Application of Climate Extreme Indices and Indicators for Monitoring Trends in
Climate Extremes and their Socio-economic Impacts in South Asian Countries
(ARCP2007-19NMY-Sheikh)
This project will be of 2 years duration is a
continuation of the 1-year concluded APN project: APN2005-10-NSY. There was a
consensus at the concluding meeting of the previous project that the new APN
project will be very helpful in promoting new avenues for research in climate
change in the participating countries. The Team Leaders and the Resource Person
agreed in principle to be a part of a new 2-year proposal to APN by extending
the work of the present project based on a wider network of stations (as the
digitized metadata used in the 1-year APN2005-10-NSY project was less) and
explore the influences of natural variability and greenhouse warming etc. on
trends in extreme indices in South Asia.
The proposed project will build upon the work done in
the one-year APN Project: APN2005-10-NSY and use a list of 27 ETCCDMI core
climate indices (compared to 19 used earlier) and an expanded network of
stations to investigate trends in climate extremes. It will then endeavour to
establish meaningful linkages between these indices and Natural Forcing
Phenomena on the one hand and extreme climate events worldwide on the other
hand.

Objectives
The main objectives of the project were:
-
High quality time-series data of key climate variables (daily
rainfall totals and maximum and minimum temperatures) for as many additional
number of stations as possible in each country will be digitized using the
guidelines and criteria adopted for such data.
-
The data will then be passed through quality control and
homogeneity testing using the software RClimDex Ver. 1.3 and RHTest. Trends in
27 core ETCCDMI indices will then be developed and national and regional maps
will be prepared. These indices will then be linked to the natural climate
variations such as El-Nino Southern oscillation (ENSO), Pacific Decadal
Variability (PDV) and North Atlantic Oscillation/Northern Hemisphere Annular
Mode (NAO/NAM).
-
The two technical meetings (one in each year) of the country
team leaders and representatives (3 in case of India and 2 each from other
countries) will have the work carried out by each country discussed in length
and finalized for research publications by each country.
Studies related to this will be taken up separately by each participating country and will be developed to the level of
publications in international climate journals.
