Jalpaiguri, nestled in the foothills of the Himalayas in West Bengal, India, occupies a geographically complex and strategically important position. Located at approximately 22.78°N, 88.57°E, the city sits at an elevation of around 118 meters (387 feet), influencing local weather patterns and air circulation. The surrounding landscape is a vibrant tapestry of the Dooars region, characterized by lush tea plantations, dense forests, and the fertile plains fed by rivers like the Teesta and Mahananda. This proximity to agricultural zones, while economically vital, contributes to seasonal agricultural burning, a significant source of particulate matter. To the north, the Himalayan range acts as a barrier, sometimes trapping pollutants and exacerbating inversions, particularly during cooler months. The city’s location along National Highway 31, a major transportation artery, results in considerable vehicular emissions. Jalpaiguri’s urban character is a blend of traditional markets and modern infrastructure, with a growing industrial belt to the east focusing on tea processing and light manufacturing. The urban-rural gradient is relatively sharp, with agricultural land quickly giving way to urban sprawl. The Teesta River, flowing nearby, can sometimes offer a degree of localized air cleansing through precipitation, but its impact is limited by the scale of pollution sources. The region's subtropical climate, with distinct wet and dry seasons, further shapes the city’s air quality dynamics, influencing dispersion patterns and pollutant accumulation.

Jalpaiguri’s air quality follows a distinct seasonal cycle dictated by the region’s monsoon climate. The monsoon season, typically from June to September, brings relief from accumulated pollutants due to frequent rainfall and strong winds that effectively disperse emissions. However, the pre-monsoon period (March-May) often witnesses a significant deterioration in air quality. Rising temperatures and decreasing wind speeds create conditions conducive to temperature inversions, trapping pollutants close to the ground. Agricultural burning, prevalent during this period as farmers clear fields for the new planting season, adds substantially to particulate matter. The dry winter months (November-February) also present challenges. Cold, calm conditions and frequent fog episodes limit vertical mixing, leading to pollutant build-up, particularly from vehicular traffic and industrial sources. While the Himalayan barrier can sometimes block pollutants, it can also trap them under stable atmospheric conditions. October is generally a transitional month, with improving air quality as the monsoon recedes but before the winter inversion season fully sets in. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the pre-monsoon and winter months, limiting outdoor exertion and considering the use of air purifiers. During the monsoon, while generally cleaner, heavy rainfall can still lead to localized flooding and associated waterborne health risks. Maintaining awareness of local weather forecasts and air quality reports is crucial for informed decision-making regarding outdoor activities.
