The Ganges Delta has been shrouded in a thick layer of fog this winter, its normally vibrant waters and lush green landscape obscured by low-hanging clouds.
On January 6, 2026, NASA's Terra satellite captured an image of the delta, showing a T-shaped area of low white clouds that stretched across the delta. The clouds were part of a larger band that extended over the Bay of Bengal in parallel rows, known as cloud streets. These cloud formations are caused by cold air passing over warmer open water, gaining heat and moisture as it rises.
While the scene may appear scenic from above, foggy conditions can be hazardous on the ground. In Dhaka, the international airport was severely disrupted due to dense fog early in the month, with flights being diverted one after another. Travel delays on roads and railways were also reported in parts of northern, central, and eastern India.
For NASA Earth Observatory, the image was captured using MODIS data from NASA's EOSDIS LANCE and GIBS/Worldview. The story behind the image was written by Kathryn Hansen.
