Synergistic Activities

      Because of his broad background in Physics, Mathematics, Computer Science and Management, Prof. Avinash C Pandey has always been interested in using his formal training in fields outside Physics. This has led to identification of a project proposal “Application of Mathematical Methods in Archaeology” for which DST has decided to extend the financial support.

      Application of Mathematical Methods in Archaeology: for answering archaeological questions objectively, with the help of emerging tools along with the standard mathematical techniques shall be identified and a compendium shall be compiled for the benefit of Indian Archaeologists. 

Impact of the contributions in the field concerned:

Simulation studies of Atmosphere & Ocean: The area of work of Prof Pandey focused mainly on Southern Ocean, which was less explored by Indian Scientists. He explored the importance of Southern Indian Ocean in influencing the Indian summer monsoon and vice versa by employing state-of-the art statistical techniques. His work shows the exclusive impact of extreme high latitude SST on Indian Monsoon Rainfall variability and if these findings are used in conjunction with other empirical predictive schemes, the early prediction of the Indian monsoon could be improvised. The behavior of air-sea interaction in extreme Southern Ocean has also been studied by designing different modeling experiments from coupled general circulation models. The variability of sea ice concentration on temporal and spatial scale, prediction of sea-ice concentration and its connectivity between the polar to extra-tropical region has been explored by him.

He also investigated the Indonesian throughflow (ITF), which is responsible for exchange of water and heat between the Indian and Pacific Ocean basins, and its impact on the Southern Indian Ocean (SIO) dynamics. His work shows that the blockage of throughflow channels and surface wind forcing has significant impact on the SIO.

Non Linear techniques:

Forced Lorenz model as a conceptual model for predictability studies has been explored in a greater detail by Prof Pandey. He has shown that these low dimensional models (forced Lorenz model) can be directly used for the study of monsoon predictability and in the process he has demonstrated the influence of slowly varying SST forcing on the Indian summer monsoon rainfall. It has also been shown that these conceptual models may be helpful in better understanding of the dynamics and occurrence of active and break spells of the Indian summer monsoon.

Errors in prediction by Farmer–Sidorowich (locally linear prediction technique) and Artificial Neural Network (global technique) for the regions of error growth and error decay in the Lorenz model are explored and compared with each other. In his leadership the group has shown that the intra-seasonal and inter-annual structure of the Indian Summer Monsoon Rainfall has undergone important structural changes in the last three decades.

Some paths to explore

For weather research:

Through seasonal prediction he is sensing the need for a strong Weather Research Programme with a scientific vision or plan which would include a strong socio-economic component. This would assist the efforts to establish a dialogue between the traditional meteorological community and end users of their research or products. In this endeavor he will focus on particular sectors such as health, security, energy, agriculture or ecosystems.

For atmospheric chemistry research:

Some centres are already developing real-time chemical data assimilation systems using space based remote sensing for some chemical species and some are running coupled chemical-weather prediction systems. Furthermore, the extension to climate modeling systems is already happening presenting further proof that the concept of unified Earth system modeling systems should be pursued. One of his students has developed a module of simulation of bio geo chemical tracers for MIT GCM from this aspect and he would like to extend this work further.

For research infrastructure.

He would explore ways to increase the visibility of our programmes to the academic community. He has worked out several exchange programmes with US Universities including John Hopkins, George Mason and COLA. He shall develop a state-of-art laboratory for the department for practical demonstration of some of the concepts taught in the course.

Maintaining Interdisciplinarity:

He has employed his training in physics and nanotechnology for understanding the self assembly and self organization by closely looking some of the photoplankton viz. Diatoms collected from Southern Indian Ocean.

For modeling studies:

Modelling (and data assimilation) is the integrator of measurements. It allows one to estimate observation and representativeness errors, help in the monitoring of observations and calibration of instruments, provide value-added products by merging different data types, validate data, and provide scientific interpretation of data. In this respect, ground-based data is very important for bias correction. At the same time, comparison with (and assimilation of) measurements improves the models, which leads to improved understanding of the atmosphere and an improved predictive capability.

Prof. Avinash Chandra Pandey, MSc(Physics, Mathematics), MTech(Computer Science), DPhil, Associate (ICTP), Professor & Head, Department of Atmospheric & Ocean Sciences, University of Allahabad and Principal Investigator in more than ten externally funded projects worth multi crore at K Banerjee Centre of Atmospheric & Ocean Studies, M N Saha Centre of Space Studies and Nanophosphor Application Centre has built up at University of Allahabad two distinct groups dealing with various aspects of mathematical modeling of atmosphere and ocean with special reference to oceanic system memory and non-linear chaotic system.

In this process, Dr Pandey has introduced widely recognized innovations in experimental techniques in order to understand the effect of oceanic system memory on regional climate by “modeling, observational and data diagnostic” study on entire Southern Indian Ocean to simulate large scale ocean circulation using Ocean General Circulation Models and by employing state-of-art statistical techniques and multi-model ensemble is another significant contribution.

From the very inception Prof Pandey is associated with the K Banerjee Centre of Atmospheric & Ocean Studies University of Allahabad as Principal Investigator of externally funded time bound projects from the last 10 years and has guided 10 D.Phil. students out of which 4 have been awarded doctorate degree. Among them three have joined as faculty member and remaining are working with International & National Laboratories as Scientist. He led several groups of his PhD students for Targetted Training Activity at ICTP, Trieste. Being Centres of Mathematical Modelling for Atmospheric and Oceanic Sciences, these centres are equipped with high performance computing facilities. As Principal Investigator to these twins Centres he has implemented various research projects funded by funding agencies.

He has been contributing to Seasonal Prediction science by Multi Model Ensembles and thus have been identified as key partner to promote scientific co-operation among India, Brazil and South Africa and specifically to share and exchange the considerable expertise and knowledge in the fields of Ocean Science and Technology.

He has published number of research papers in peer reviewed international journals of repute in the areas of predictability from non linear dynamical perspectives, data diagnostics, oceanic system memory with special reference to cryo sphere and its role in climate change, simulation of oceanic phenomenon and transport mechanism.

He is also working in collaboration with COLA for the societal project on seasonal prediction for the end users of districts of Eastern UP(highest population density).

He has promoted the growth of user facility and capacity building in front ranking areas by developing state of art facility through project funding that includes High Performance Computing Facility for Simulation Experiments, Wet Laboratory with clean room, Sophisticated Instrumentation including 300 KV HR TEM, SEM, AFM, STM, MFM, NSOM, Micro RAMAN, TMA/TG-DTA, Nano Indenter, XRD /SAXS, PL/PLE/UV-Vis spectrometer, High Performance Computing Facility for Simulation Experiments. He is currently applying his expertise of nano science in understanding the self assembly in diatoms.

His innovative leadership has resulted in creation of two new disciplines in Physics department as its off-shoots in University of Allahabad. In another significant achievement Dr Pandey’s proposal to fill the gap in accelerator grid in India through High Fluence Ion Beam Facility (Ion Implanter) in University System is a trend reversal.
