sciforum-076762 | Unraveling the Influence of the Atlantic Subpolar Gyre on the Thermohaline Circulation for the Past 20,000 Years. |
,

Show Abstract |
||||||||||||||||||||||||||||||||||||
Recent studies have widely implicated that the strength of the North Atlantic subpolar gyre (SPG) is dynamically linked with the North Atlantic thermohaline circulation, affecting the subpolar marine environment. Therefore, it is crucial to understand the past changes in the SPG strength with changes in arctic sea ice and Atlantic meridional overturning circulation (AMOC). This climate modeling study employs a fully coupled atmosphere-ocean-sea ice Earth system model to explore the dynamics in the North Atlantic subpolar for the past 20ka (ka is thousand years before the present). This study highlights a close relationship between the strength of the SPG, Atlantic sea ice coverage, and AMOC circulation in the centennial timescale resolution for the past 20ka. The simulation shows that the changes in SPG and AMOC are in phase. However, the Atlantic sea ice coverage varied inversely to SPG and AMOC strength. Particularly during the Heinrich 1 (≈19ka–14.6ka) and Younger Dryas (≈12.9ka–11.7ka) events, the SPG strength decreased in unison with AMOC strength which reduced the northward meridional heat transport and resulted in the increase in the Atlantic sea ice coverage. However, the dynamic linkage between Atlantic sea ice coverage and ocean circulation does not follow during the prescribed unnatural freshwater supply during the meltwater pulse 1A (mwp-1A) event at about 14.1ka, which caused the Allerød warm period (≈14ka–12.9ka). This finding demonstrates that an abrupt change in freshwater discharge into the North Atlantic subpolar may destabilize the polar ocean-sea ice dynamics. |

sciforum-076613 | Air Pollution Resulting From Biomass Combustion In Mozambique: Origins, Consequences, And Measures For Mitigation |

Show Abstract |
||||||||||||||||||||||||||||||||||||
Air pollution is a major environmental concern with far-reaching consequences for human health, ecosystems, and sustainable development. Air pollution resulting from biomass combustion is a significant environmental issue in Mozambique. This study provides an overview of the impact of biomass burning on air quality in the country, focusing on the sources of pollution, emitted pollutants, and the associated health and environmental implications. Mozambique heavily depends on biomass for cooking, heating, and energy production, leading to elevated levels of air pollution caused by burning biomass fuels like wood, agricultural residues, and charcoal. Particulate matter (PM), carbon monoxide (CO), nitrogen oxides (NOx), volatile organic compounds (VOCs), and hazardous air pollutants (HAPs) are all emitted into the atmosphere when biomass is burned. These contaminants harm human health, leading to respiratory and cardiovascular disorders. Furthermore, biomass combustion emits greenhouse gases, including carbon dioxide (CO2) and methane (CH4), contributing to climate change and global warming. Reducing air pollution caused by biomass in Mozambique is crucial for safeguarding public health and the environment. Initiatives promoting cleaner cooking technologies, such as improved cookstoves and biogas systems, aim to reduce dependence on traditional biomass burning. Additionally, raising awareness about the health risks associated with biomass combustion and ensuring access to alternative energy sources are essential steps in addressing this problem. However, challenges like limited access to clean energy options, financial constraints, and the need for sustainable biomass management techniques persist. To tackle biomass-related air pollution in Mozambique, comprehensive solutions require collaborative efforts involving the government, non-governmental organisations, and international partners. This paper offers an overview of biomass-related air pollution in Mozambique, concentrating on the sources, impacts, and potential solutions. Mozambique can considerably improve air quality, safeguard public health, and contribute to sustainable development by using cleaner cooking technology, supporting sustainable biomass management practices, and raising awareness. |

Atmospheric aerosols play a crucial role in the scattering and absorption of solar radiation, directly influencing the UV flux reaching the Earth's surface. This study investigates the impact of different atmospheric aerosol types on the ultraviolet (UV) flux at four stations over Indo-Gangetic plain (IGP). For this study, high-resolution 1°x1° UVA and UVB data was obtained from Clouds and the Earth's Radiant Energy System (CERES). Various aerosol types present in the atmosphere were categorized based upon their optical properties and their quantitative influence on UVA and UVB flux was examined. Ground-level aerosol products were obtained from the NASA-based Aerosol Robotic Network (AERONET) at four stations in the IGP. Based on the optical properties of aerosols (fine mode fraction, single scattering albedo, aerosol optical depth and angstrom exponent), four distinct atmospheric aerosol types were inferred, namely, dust dominant (DT), anthropogenic aerosols dominant (AAD), black carbon dominant (BCD), and organic carbon dominant (OCD). OCD and AAD showed the highest concentration at Kanpur and Lahore respectively whereas BCD showed lowest contribution at Karachi and Jaipur. The UVA and UVB fluxes were found to be highly influenced by DT at Jaipur, OCD at Kanpur, BCD and OCD at Karachi and DT at Lahore. As the UVA and UVB flux are affected by solar zenith angle and ozone column concentration, the effects of the same has also been studied on UVA and UVB for different aerosol types. |

Delhi is one of the most densely populated megacities of the world and is experiencing deteriorating air quality due to rapid industrialization and excessive use of transportation. The limited emission control measures in Delhi have led to worsening air quality problems, which have become a serious threat to human health and the environment. In the present study, we investigate the long-term (2011-2021) interrelationship between air pollutants and vegetation index using satellite datasets. Air pollutant data viz. nitrogen dioxide (NO2) and sulfur dioxide (SO2) obtained from NASA’S Aura satellite called Ozone Monitoring Instrument (OMI), and carbon monoxide (CO) and particulate matter 2.5 (PM2.5) from Modern-Era Retrospective analysis for Research and Applications version 2 (MERRA-2) model. The vegetation indices i.e. Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Oxide (EVI) collected from the Terra Moderate Resolution Imaging Spectroradiometer (MODIS) satellite. The analysis of both data revealed higher concentrations of air pollutants in the summer months when NDVI & EVI was minimum. Further, a higher pollution load was observed in October – January months when NDVI and EVI were lower. Furthermore, we also investigated the spatial patterns of PM2.5 and other gaseous pollutants (viz. CO, SO2, and NO2) and observed that they were less in the vegetated region in comparison to the sparsely vegetated area of Delhi. The present study indicates vegetation could ameliorate various air pollutants, however, it needs to validate with ground observed data. |

sciforum-076211 | THE SOLAR INFLUENCE ON TROPICAL CYCLONES OCCURES OVER BAN OF BENGAL AND ARABIAN SEA AREA | N/A | N/A |
Show Abstract |
|||||||||||||||||||||||||||||||||||||
During last few decades a prominent example of extreme weather event in Indian Ocean region is Cyclonic Storm. In this paper annual variation of different categories of tropical Cyclonic Storms like Tropical over Bay Of Bengal (BOB) and Arabian Sea (ARS) have been analyzed .The analysis revels that the total number of cyclone (TNC) has increased with high rate (gradient being +1.67 per year) and although C.S. is more over BOB than that over ARS. The rate of increase of C.S. over Arabian Sea is more than that over Bay of Bengal. Furthermore, two interesting features have been noted: (i) Monsoon tends to prohibit the formation of C.S (ii) Cyclonic Storm(C.S.) increases with the increase of Global Sea Surface Temperature (GSST) during said period. An attempt has also been made to find out the influence of solar activity on these extreme weather events. Keeping in mind that the Sun Spot Number (SSN) is an indicator of the strength of solar effects, it has been found that in most of the times the high value of SSN is associated with small number of total cyclone (C.S.). High SSN (> 90) and number of cyclones shows high Correlation coefficient (0.78) .Significance at 99.99% level while Correlation Coefficient (C.C.) of cyclones with time is 0.53 and with SSN < 60 it is0.095 . Thus it appears that although C.S. frequency is increasing with time, Sun’s Spot’s influence is such that it basically opposes the formation of cyclone provided SSN exceeds certain critical value (roughly 90). |
