Purpose: The aim of the study was to assess the economic factors influencing the abolition of slavery in the British empire.
Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries.
Findings: The study revealed significant impacts on monsoon patterns and intensity. Anomalies in SST, particularly in key regions such as the Indian Ocean, the Pacific Ocean, and the Atlantic Ocean, can disrupt typical monsoon behavior, leading to variations in precipitation, wind patterns, and seasonal onset and retreat. For instance, warmer-than-average SSTs in the Indian Ocean can enhance monsoon rainfall by increasing moisture availability and convection. Conversely, cooler SSTs can lead to weaker monsoon activity. The El Niño-Southern Oscillation (ENSO) phenomenon, characterized by warm (El Niño) or cool (La Niña) phases in the Pacific Ocean, plays a pivotal role in modulating monsoon variability. El Niño events typically result in suppressed monsoon rainfall over the Indian subcontinent, while La Niña conditions generally enhance monsoon rains. These SST anomalies affect atmospheric circulation patterns, including the strength and position of the monsoon trough and the subtropical jet stream, further influencing monsoon dynamics. The complex interplay between SST anomalies and monsoon variability underscores the importance of monitoring oceanic conditions for accurate seasonal weather predictions and effective climate adaptation strategies.
Implications to Theory, Practice and Policy: Teleconnection theory, walker circulation theory and Indian ocean dipole theory may be used to anchor future studies on assessing the influence of sea surface temperature anomalies on monsoon variability in South Asia. To mitigate the adverse effects of monsoon variability on agriculture, it is crucial to promote the adoption of climate-resilient agricultural practices. Formulating and implementing integrated climate policies that address the impacts of SST anomalies on monsoon variability is essential.
