2002 to undertake a project on 'Climate: Its variability and
change over Trinidad and Tobago' as part of the Advance
Met. Course of IMD, Pune.
two people are working for their Ph.D. under my
supervision. These students are primarily working in the
areas of (1) Evaluating the simulation of low-frequency
(Madden-Julian and other) oscillations in the monsoon
rainfall over the Indian region in different atmospheric and
coupled ocean-atmospheric models and likely future changes
in different climate change scenarios and (2) Impacts of
interannual monsoon variability and Climate Change on the
water resources of major river basins in India, respectively.
Professional Experience:
I have been working at Indian Institute of Tropical Meteorology, Pune, India since 1982
in various capacities engaged in full time research in Meteorology and Atmospheric Sciences.
Needless to say, like most climate scientists in India, my focus of research has been to
understand the nature of monsoon variability and see how best one can predict the monsoon
rainfall on different spatial and temporal scales. In this pursuit, I have gained very useful
experience working with a large volume of observed meteorological data on various important
climatic factors for the Indian region in various analyses carried out during the initial stages of
my work which has given me a great insight into various aspects unique to monsoon climate
over this region. However, during the last 6 or 8 years, I have been carrying out diagnostic
studies involving simulation data from different atmospheric and coupled ocean-atmosphere
general circulation models (GCMs) and also conducted various sensitivity experiments using
GCMs to understand monsoon rainfall variability and the impact of sea surface patterns in the
Indian and the Pacific Oceans. During the course of my long research career in one of the
premier research centers on Atmospheric research in India, I have organized several national
and international conferences/symposia, besides conducting training programs on climate issues
to agricultural scientists engaged in disseminating climate information. Though the nature of
my job is a full-time researcher, I am a recognized research supervisor for M.Tech and Ph.D.
graduates in Atmospheric Science of Pune University and Andhra University in India. I am
working as one of the principal investigators/collaborators in various national/bilateral/
multinational research projects related to climate applications, development of climate change
scenarios using regional climate models and impact studies. The success of any climate
application study would primarily depend on the accuracy and reliability of monsoon forecasts
on different spatio-temporal scales. In this connection, my ongoing collaborations with
scientists working at some of the leading climate centers like the IRI (USA), Hadley Center
(UK), MPI (Germany), and MRI (Japan) have been proving to be very productive in improving
boss11CV of Dr.K. Krishna Kuamrboss11
our understanding of monsoon variability and the prediction. I strongly believe the possibilities
of collaboration with the scientists at CDC, NCAR, UC-Boulder, CIRES would advance our
understanding of the unusual behavior of monsoon and its global teleconnections in the recent
decades by way of conducting useful diagnostic studies and GCM experiments. Besides, the
Asian monsoon is known to influence the weather and climate else where in the world and
therefore, the successful and realistic simulation of monsoon in GCMs is very necessary for
improving the global climate forecasts in general.
Peer reviewed several research papers submitted to some of the prestigious journals like
Science, Journal of Climate, Geophysical Research Letters and many other Indian journals.
International Centers Visited
1.IRI, Columbia University, New York, University of Colorado, Boulder and Hadley Center for
Climate Prediction, UK during 18 November - 7 December, 2002 (Hosts: Drs. James Hansen
(IRI), Balaji Rajagopalan (CU) and Geoff Jenkins(UK Metoffice))
Recent visits to the above mentioned centers in connections with my ongoing bilateral and multinational collaborative research projects have proved to be very fruitful and useful in continuing the
proposed research tasks under these programs and more so in planning future collaborative works in
the areas of monsoon variability and prediction/impacts of global climate change on various facets of
monsoon variability and global teleconnections. This visit has also provided me an opportunity to
meet many scientists working with Univ. of Colorado, Boulder, CIRES and CDC-NOAA having
common research interests and plan some collaborative research themes/areas with a possibility to
pursue them under the CIRES visiting fellows program in the coming year.
2.Meteorological Research Institute (MRI), Tsukuba, Japan, 3 months (March-June, 2001;
Host: Dr. M. Sugi)
Visited MRI, Japan on a STA fellowship program. During this visit a six member ensemble
Atmospheric General Circulation Model (AGCM) runs made with observed global sea surface
temperatures (SSTs) during 1949-1997 have been analyzed to examine the model's ability to simulate
various global climatic features such as the Indian summer monsoon, North Atlantic Oscillation
(NAO) etc. and their interannual variability. These runs were made at the Meteorological Research
Institute (MRI) of the Japan Meteorological Agency (JMA), Tsukuba, Japan. Apart from the general
climatological features, emphasis was given to examine in detail the Indian monsoon rainfall
simulation in the model and its tele-connections with El Nino-Southern Oscillation (ENSO). The
analyses show several encouraging positive aspects of the model simulations while the inherent
deficiencies brought out suggest the need for further improvements in the model physics and
parameterizations. These highly computationally expensive 6 member ensemble runs were also
utilized to study the predictability (internal vs SST forced variability) aspects of various global
meteorological variables such as the precipitation, surface temperature, sea level pressure etc. A
research paper based on the above work is being prepared.
3.Max-Planck Institute for Meteorologie (MPI), Hamburg, Germany, 2 months (May-June,
2000; Host: Dr. M. Latif)
Though short, this 2-month visit to MPI has given me an opportunity to design and perform a set of
atmospheric general circulation model (AGCM) experiments by forcing ECHAM3 (T21) model with
different sea surface temperature (SST) patterns in the Indian and the Pacific Oceans to understand
various issues concerning the secular changes in monsoon-ENSO relationships. The possible impact
of recent continental warming on the connection between the Indian monsoon activity and the SSTs in
the Indo-Pacific region has also been assessed with additional sensitivity experiments by doubling the
CO2 concentration with fixed SST patterns in the ocean. These sensitivity experiments suggest
significant differences in the response of the Indian monsoon to the differences in the SST patterns
associated with different El Nino events. Building on these preliminary efforts, more extensive
additional experiments could be designed and performed in close collaboration with scientists at
CDC and/or NCAR during the proposed fellowship tenure to understand the possible impact of recent
tropical basin-wide sea surface temperature warming on the well-known monsoon and global
boss11CV of Dr.K. Krishna Kuamrboss11
4.International Research Institute for Climate Prediction (IRI), LDEO, Palisades, NY, USA, 2
years (July 97 - June 99; Collaborated with Prof. Mark Cane)
This two year visiting post-doctoral research scientist assignment at IRI has provided me ample
opportunities to address various issues concerning monsoon variability and predictability in general
and the inter-decadal variations in the strength of monsoon-ENSO linkages in particular. Also, this
visit has helped me to steer my research efforts towards possible applications in agriculture, water
resources, human health etc. having direct societal benefits. My involvement, of late, in various
national and multi-national projects with the primary focus on climate applications in various fields
bears testimony to this new pursuit.
5.International Research Institute for Climate Prediction, Palisades, NY, USA, 9 months
(March-December, 1994; Project done with Dr. S.E. Zebiak)
This carefully designed and well organized 9-month long international training program was very
useful in many ways. Excellent course program and numerous invited guest lectures by leading
personalities in the fields of seasonal prediction and ENSO forecasting besides climate
applications formed a formidable foundation and basis for my research during the last 8 years
after that. Working together with colleagues with varied backgrounds from different parts of the
globe gave an unique experience to learn from each others strengths and establish global links
necessary for further collaborative programs. Overall, the program was a very fruitful and
gratifying academic experience.List of Publications of Dr. K. Krishna Kumar
