ATMOSPHERIC WATER VAPOR MEASUREMENTS AND CLIMATE CHANGE

I am working on the broader aspects of precipitable water vapor measurements and its effect on climate change. As far as now we are working on the trends over indian region for precipitable water vapor in the tropospheric water vapor level and trying to figure out its effect on climate change over the whole indian region and also over its several regions.

We will also give our focus onto figuring out a solid understanding of the mechanism by which precipitable water vapor and its changes over time influences atmospheric processes. Then we will try to figure out about the precise knowledge of its concentration in the stratospheric region and also about the understanding of mechanisms by which it influences atmospheric processes. We will also try to figure out the solid reason behind the stratospheric water vapor change which is assumed to be caused by climate feedback or some internal variability and also see the long term trends of it.

Overall our point of purpose will be developing a solid understanding

OBJECTIVES

SOCIETAL IMPORTANCE

This will help to develop a certain level of understanding about the mechanism by which water vapor influences some atmospheric processes and also about some factors which controls the
water vapor amount in atmosphere. The long term trends over time of precipitable water vapor will help us to have depth of knowledge about those region’s particular climate change patterns and also its effects on socio-cultural processes.

• Derivation of climatology of rainfall based on 8-10 years Radar data at one or more location in India.

• Weather radars provide surface rainfall intensity estimates based on Marshal Palmer relation, these estimates have high spatial and temporal resolution in comparison to surface observation network. Hence, an attempt to derive climatology of rainfall based on weather radar past 8-10 yrs data is being made. This work serves two purposes: first namely derivation of climatology of rainfall based on Doppler weather radar 8-10 yrs data. Second is to prepare climatology for extreme weather events associated with Western Disturbance such as hailstorm, thunderstorm which impacts northern India during winter months mainly.

OBJECTIVES

• It would be useful for IMD (India Meteorological Department) to have a catalogue of climatology of rainfall events over a particular area.
• Climatology of radar rainfall could be utilised for climatological application such as estimation of probabilities of extreme rainfall which is used for design purposes in water management.
• Climatology of extreme weather events along with hydrometeor details could be utilised by forecasters and academics & designers associated with water management.

SOCIETAL IMPORTANCE

• The climatology results can be utilised by various departments working in disaster management related services.

Long-Term Changes in Winter Blooms in the Arabian Sea: Characteristics and Physical Forcing

The Winter bloom in the Arabian sea, which is in conjunction with the North Easterly winds had been subjected to spatio-temporal changes during the last decade. Our research interests are focused on the role of oceanic and atmospheric forcings in influencing the bloom characteristics. We use reanalysis, observation, and numerical models to understand the process that drives the bloom.

OBJECTIVES

• Long-term changes in winter bloom of Arabian Sea
• The drivers of winter bloom and its temporal changes

SOCIETAL IMPORTANCE

Phytoplanktons form the base of the marine food web and recent changes in the ocean condition and plankton composition in the Arabian Sea had adverse effect on the Net Primary Productivity, carbon budget and marine fisheries. Scholarly attention in plankton blooms especially HABs and hypoxia followed by it helps to lessen the harm done to the ocean ecosystem and to the human environment.

Tropospheric and Surface Ozone over the Tropics and the Extra tropics: Past, Present and Future.

Ozone is a gas made up of three oxygen atoms (O3). It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). Ozone protects life on Earth from the Sun’s ultraviolet (UV) radiation. In the lower atmosphere (the troposphere) near the Earth’s surface, ozone is created by chemical reactions between air pollutants from vehicle exhaust, gasoline vapors, and other emissions. At ground level, high concentrations of ozone are toxic to people and plants.

Although ozone in the stratosphere is beneficial as it shields life on Earth from harmful radiation, direct exposure to ozone at ground level can be detrimental to both plants and animals, including humans. Ground-level ozone, also known as "bad" ozone, is formed when nitrogen oxide gases, typically emitted by vehicles and industries, react with volatile organic compounds like paint thinners, which easily evaporate into the air. In the troposphere, which is close to the Earth's surface, the natural concentration of ozone is approximately 10 parts per billion (0.000001 percent).

According to the Environmental Protection Agency (EPA), exposure to ozone levels exceeding 70 parts per billion for more than 8 hours is considered unhealthy. Such concentrations are often found in or near urban areas during periods when the atmosphere is warm and stable. The harmful effects of high ozone levels can include irritation of the throat and lungs, as well as the exacerbation of respiratory conditions like asthma or emphysema.
