Periyakulam, nestled in the Theni district of Tamil Nadu, India, occupies a unique geographic position within the foothills of the Western Ghats. Located at coordinates 10.1239°N, 77.5475°E, the town’s terrain is characterized by gently sloping plains transitioning into steeper, forested hills. This proximity to the mountains significantly influences local weather patterns and air circulation. The town’s elevation, approximately 280 meters above sea level, contributes to temperature variations and potential for temperature inversions. Periyakulam is not directly adjacent to major bodies of water, though the Mullaiyar River flows nearby, providing irrigation for the surrounding agricultural lands. The region is predominantly agrarian, with significant cultivation of vegetables, flowers, and spices. This agricultural activity, while economically vital, contributes to seasonal biomass burning, impacting air quality. The urban-rural gradient is relatively sharp; Periyakulam serves as a market town for numerous smaller villages, leading to increased vehicular traffic and localized pollution concentrations. The surrounding landscape is a mosaic of agricultural fields, interspersed with patches of scrubland and forested slopes. The town’s location within a valley can also trap pollutants, exacerbating air quality issues during calm weather conditions. Industrial activity is limited, but small-scale brick kilns and processing units contribute to particulate matter emissions.
Periyakulam experiences a tropical climate with distinct wet and dry seasons, profoundly impacting air quality. The southwest monsoon, arriving in June and lasting through September, brings heavy rainfall which temporarily washes pollutants from the air, resulting in generally improved air quality during these months. However, increased humidity can also foster mold growth, impacting respiratory health. October to December sees a retreating monsoon with intermittent showers, and a gradual build-up of pollutants as agricultural residue burning increases post-harvest. January to March are the driest months, characterized by clear skies but also the highest pollution levels. Dry conditions and stagnant air allow particulate matter from construction, vehicular emissions, and agricultural sources to accumulate. Temperature inversions are common during these cooler months, trapping pollutants near ground level. April and May are intensely hot, with strong convective winds that can disperse pollutants, but also increase ozone formation. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during the dry season, particularly January to March. Wearing masks and avoiding peak traffic hours are recommended. Monitoring local conditions is crucial, as wind patterns can change rapidly.
