Tropical cyclones are one of the most devastating storms. Though it is
disastrous, it also has some positive effects such as bringing rainfall, decreasing
pollutants etc. Our North Indian Ocean which has Bay of Bengal and Arabian
Sea is home to tropical cyclones and also it is warmest of all oceans. In the
context of climate of climate change, it is important to consider the impact of
tropical cyclones on it. In the recent years, there is an increase in the number of
tropical cyclones and 2019 being an anomalous year as far 2019 is concerned.
Therefore, the effects of tropical cyclones on climate change has to be
understood.

With severe impacts on human health and agricultural output (crop damage in India upto 3.5 million tonnes a year, tropospheric ozone is a prominent air pollutant and greenhouse gas in spite of being only 10% of total column amount.

However, Ozone is not only a greenhouse gas and biological irritant but also an atmospheric cleansing agent which rids the atmosphere off hazardous gases through production of hydroxyl radicals and is beneficial if it is present in the stratosphere in abundant amount as it prevents harmful sun rays from penetrating through the troposphere to the Earth’s surface. Ozone exerts considerable radiative forcing too with recent estimate being 360 mW/m2 which is 25% of the same exerted by CO2.

Climate variabilities ranging from interannual to decadal scales like El Niño and the Southern Oscillation (ENSO), Pacific–North American teleconnection (PNA), North Atlantic Oscillation (NAO), Antarctic Oscillation (AAO), Pacific Decadal Oscillation (PDO) etc. has been reported to influence the tropospheric ozone at remote locations.

Despite of having tremendous climatic, agricultural, compositional and health repercussions, variability of ozone (tropospheric in particular) vis-a-vis circulation changes (due to climate change and stratospheric ozone hole recovery) is still poorly understood.

Given this background, it is imperative to ask the following relevant questions:

o How is the ozone in the Antarctic distributed both vertically and spatially?

o Is the ozone hole in the stratosphere healing? If yes, how confident are we about our analysis showing the recovery trends?

o Is there any evidence of recovery in atmospheric layers which experience near complete destruction of ozone i.e. ozone loss saturation layers?

o How is the recovery affecting the tropospheric ozone trends?

o How do O3 profiles cluster for various regions, each of which are known to exhibit differing O 3 distributions?

o What are the links among the O3 profile clusters, meteorology, and chemistry, and how do they depend on latitude or region?

o How do the ozone recovery in the stratosphere and trends in tropospheric ozone affect the surface climate in the Antarctic and how is it correlated with the increasing greenhouse gases?

I’ll be using state of the art Physical models and Causal Discovery and Inference methods based on Artificial Intelligence to answer these questions.

I work on sustainability science (environmental sustainability) with an emphasis on food and nutritional security in climate change context. My current affiliation is with Centre for Oceans, River, Atmosphere and land Sciences (CORAL), Indian Institute of Technology, Kharagpur, India, as a doctoral candidate and working as a visiting scholar at ICRISAT Hyderabad. My research focuses on the comparative assessments of conventional and new flanged concepts to sequester carbon in soil and analysing its effect on soil carbon fractions, crop production, soil fertility and potential emissions arising from chemical fertilizer use in soil.

Soils are home to myriad micro-organisms that fix nitrogen and decompose organic matter, and armies of microscopic animals as well as earthworms and termites. My research integrates scientific principles from soil science, agronomy, biology, and chemistry to elucidate how soils provide essential ecosystem services. My research also provides an understanding of how soil properties relate to and can be managed for optimal agricultural production, and agro-waste disposal and management. I address nutrient management, sustainable agriculture, soil biogeochemical cycles and climate change.

We build on soil as well as with it and in it. Soil plays a vital role in the Earth's ecosystem. I also work on designing and production of biochar based on the need of soil. Being an agricultural systems researcher by training my focus is on agroecology and environmental footprints of agriculture. I have experience of working with crop simulation models on DSSAT platform and DNDC. Advances in watershed, natural resource, and environmental sciences have shown that soil is the foundation of basic ecosystem function. Soil filters our water, provides essential nutrients to our forests and crops, and helps regulate the Earth's temperature as well as many of the important greenhouse gases.

As our awareness of the value of natural and managed ecosystems services grows, new biodiversity, carbon, and water markets are emerging, such as the Chicago Climate Exchange, and the nutrient trading programs under the new executive order on the Protection and Restoration of the Chesapeake Bay. These markets place an economic value on management practices which increase those ecosystem services, producing goods that enhance human and environmental health.

My research area includes emissions studies from the agriculture sector. We work on quantifications of hotspots of different atmospheric gases such as NH3 and Greenhouse gases (GHG). A greenhouse gas (GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect on planets.

The primary greenhouse gases in Earth's atmosphere are water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O3). I am working on CO2 and CH4 as a part of my doctoral thesis. Over the last fifty years, the increase in agricultural production to meet the food demand of a growing population has resulted in a near doubling of GHG emissions from agriculture, forestry and fisheries. Globally, agriculture faces the triple challenge of increasing production to meet the growing food demand, adapting to changing climatic conditions and reducing agricultural emissions from the fields. Agricultural emissions basically constitute greenhouse gases (GHG) and non-greenhouse gases emissions coming from large land areas.

The changes in climate that can be expected as a result of the ongoing emissions of greenhouse gases could have large, harmful impacts on both plants and animals by making them more vulnerable to the attacks of insects/pests and diseases. Moreover, CO2 and CH4 are the topmost two gases that contribute to the greenhouse gases (GHG) emissions at a global level. This growth in agriculture and associated emissions will occur mostly in Asian and African countries, where a large percentage of the population depends on agriculture and allied sectors for their livelihoods. As per EDGAR v 4.3.2 database report of 2016, total global GHG continued to increase at the rate of 0.5% annually reaching up to 49.3 Gigatons of CO2 equivalent.

My study region is the whole of India. Since, India is the third-largest emitter of greenhouse gases (GHG) in the world after the USA and China, therefore, to reduce the emissions at the global level, India has a vital role to play. The agricultural sector is responsible for 18% of gross national GHG emissions in India too mainly through rice cultivation, livestock production, fertilizer use and burning of crop residues. Continued emissions of greenhouse gases will lead to further climate changes. Future changes are expected to include a warmer atmosphere, a warmer and more acidic ocean, higher sea levels, and larger changes in precipitation patterns. The extent of future climate change depends on what we do now to reduce greenhouse gas emissions. The more we emit, the larger future changes will be.

Greenhouse gas concentrations in the atmosphere will continue to increase unless the billions of tons of our annual emissions decrease substantially. Increased concentrations are expected to increase the earth’s average temperature, influence the patterns and amounts of precipitation, reduce ice and snow cover. It will raise the sea level, increase the acidity of the oceans, increase the frequency, intensity or duration of extreme events, shift ecosystem characteristics, and also increase threats to human health. These changes will impact our food supply, water resources, infrastructure, ecosystems, and even our own health.

Many greenhouse gases stay in the atmosphere for long periods of time. As a result, even if emissions stopped increasing, atmospheric greenhouse gas concentrations would continue to increase and remain elevated for hundreds of years. Moreover, if we stabilized concentrations and the composition of today's atmosphere remained steady (which would require a dramatic reduction in current greenhouse gas emissions), surface air temperatures would continue to warm.

Sudden Stratospheric Warming (SSW) is the phenomenon of rapid rise in temperature in the stratosphere for a few days time. The SSW is the result of the planetary wave interactions on the polar vortex that weakens the vortex and eventually giving rise to a vortex split or a displacement of the vortex to mid latitudes. There are two major types of SSW, a major warming and minor warming. Major warming events are distingushed by the reversal of the westerly winds. The weaker nature of the Arctic vortex in comparison to Antarctic makes Arctic more vulnerbale to SSW events.

The SSWs are studied from the changes in the meteorology of the winters and the changes in the potential vorticity (PV). The vortex splits and displacements are identified using the PV maps. Apart from these the SSW events became significant in the polar latitudes due to its direct impact on the changes in ozone depletion cycles. The ozone loss amount in the years corresponding to both major and minor warming were significantly lower than the cold winters.
