Long-term environmental patterns including humidity, wind, and daylight duration averages.
Review comprehensive climate metrics for a representative coordinate within Sundarbans National Park. These monthly normals cover average maximum and minimum temperatures, daily precipitation rates, relative humidity, wind speed, and total daylight hours recorded between 1991 and 2020. Analyze how these atmospheric variables fluctuate through the calendar year to understand the long-term climatology of this protected landscape.

Comparing twelve months of average temperature ranges and daily precipitation trends at low elevation.
Evaluating long term averages for temperature bounds, daily precipitation rates, and calculated daylight hours.
