Srungavarapukota, nestled in the Alluri Sitharama Raju district of Andhra Pradesh, India, occupies a geographically significant position within the Eastern Ghats region. Located at approximately 18.1167° N latitude and 83.1667° E longitude, the city’s terrain is characterized by undulating hills and valleys, typical of the Deccan Plateau. The elevation, though modest, contributes to localized microclimates and influences air circulation patterns. Srungavarapukota sits on the fringes of a predominantly rural landscape, transitioning from agricultural fields to denser forest cover as one moves eastward towards the hills. The surrounding area is primarily agricultural, with rice and maize cultivation being dominant, alongside smaller-scale horticulture. This proximity to agricultural zones introduces potential sources of particulate matter, particularly during harvest seasons when burning of crop residue can occur. While not directly adjacent to a major river, the region receives significant rainfall during the monsoon season, which can temporarily flush pollutants from the atmosphere. The city’s urban character is relatively small-scale, with a developing commercial center and residential areas. The lack of extensive heavy industry within Srungavarapukota itself mitigates some pollution risks, however, the potential for industrial activity in nearby regions, and the transport of goods through the area, can still impact air quality. The urban-rural gradient is gradual, with smaller villages and agricultural holdings interspersed throughout the landscape, influencing regional wind patterns and pollutant dispersal.

Srungavarapukota experiences a tropical wet-dry climate, significantly impacting its air quality throughout the year. The dry season, typically spanning from March to May, often sees a build-up of pollutants due to reduced rainfall and increased temperatures. Calm wind conditions during this period can lead to temperature inversions, trapping pollutants closer to the ground, particularly in the mornings. Dust from agricultural activities, including plowing and harvesting, also contributes to elevated particulate levels. The monsoon season, from June to September, brings relief as heavy rainfall washes away accumulated pollutants, leading to a noticeable improvement in air quality. However, the onset of the monsoon can initially be accompanied by increased humidity and localized fog, which can temporarily reduce visibility and trap pollutants. October and November represent a transitional period, with decreasing rainfall and gradually increasing temperatures. This period can see a resurgence of dust and agricultural emissions. December and January are generally cooler and drier, with occasional fog, which can again lead to localized pollutant accumulation. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season and periods of fog, limiting outdoor exertion and ensuring adequate ventilation. Agricultural workers should be mindful of dust exposure during peak farming activities. The interplay of wind patterns, temperature fluctuations, and agricultural practices dictates the seasonal air quality narrative in Srungavarapukota, demanding adaptive strategies for public health.
