Weather Patterns

The influence of moisture-laden winds, such as those brought by weather systems like western disturbances, plays a significant role. These disturbances are common in winter and can bring precipitation in the form of snow at higher elevations. These winds can carry moisture from lower altitudes to the higher elevations of Shimla, facilitating the formation of snow.

Local Climate

Shimla's local climate is characterized by a specific set of conditions that favor snow formation. Its geographical location and climatic conditions make it more susceptible to snowfall. For instance, the slope and orientation of Shimla's terrain can also contribute to the accumulation of snow, as the air cools and rises, leading to condensation and snowfall.

Conclusion

In summary, the combination of altitude, temperature variations with height, moisture availability, and local weather patterns contribute to Shimla experiencing snowfall while Delhi does not, even with seemingly comparable temperatures. Understanding these factors helps in explaining the weather phenomena observed in different parts of India.

Additional Considerations

Low Temperature and Moisture: Snowfall is a result of low temperature and moisture in the atmosphere. While Delhi's low altitude and higher surface temperature make snow formation less likely, the moisture from surrounding areas can lead to snowfall in Shimla, showcasing the importance of both temperature and moisture in this phenomenon.

By examining these factors, we can better understand why Shimla receives snowfall while Delhi remains warm, despite having seemingly comparable surface temperatures.
