Inception of Winterline: Mussoorie, Uttarakhand!!

We are already halfway through the month of September and one can observe the formation of winterline in the skies enveloping Landour and Mussoorie. The formation of the Winterline indicates that winter is slowly paving it’s way into the hillside of Landour, Mussoorie.

Winterline is a rare phenomena where a pseudo horizon is formed at dusk. A strikingly straight transition or buffer zone is created in the atmosphere due to intermixing of hot and cold air causing temperature inversion.

During sunset the sunrays refract through the moisture, dust particles and other particulates in the atmosphere and create a mesmerizing meteorological phenomena known as Winterline. It is visible from Mussoorie in India between October and February. Besides Mussoorie, India this winterline also occurs in the Swiss Alps, Europe. However, during recent years, high air pollution levels have affected the prominence of Winterline.
