The formation of clouds in this region is primarily influenced by factors such as altitude, topography, and prevailing winds. Located at a relatively low altitude, Dera Ismail Khan has a hot and dry climate throughout most of the year.

Types of Clouds in Dera Ismail Khan, Pakistan
Various types of clouds can be observed in the skies of Dera Ismail Khan, each with distinct characteristics and altitudes. Cirrus clouds, composed of ice crystals, often appear as thin wispy streaks in the upper atmosphere. Cumulus clouds, on the other hand, are puffy and cotton-like formations that usually indicate fair weather.

Additionally, during the winter months, stratus clouds, which can appear as a uniform gray layer covering the sky, may also be observed.
Seasonal Distribution
Precipitation in Dera Ismail Khan exhibits a pronounced seasonal pattern, with distinct wet and dry periods. The wet season, extending from July to September, coincides with the southwest monsoon winds bringing moisture-laden air from the Arabian Sea.

The annual precipitation in Dera Ismail Khan is approximately 300 mm, with considerable interannual variability.
Factors Influencing Precipitation
The primary factor influencing precipitation in Dera Ismail Khan is the seasonal movement of the Intertropical Convergence Zone (ITCZ). During the monsoon season, the ITCZ shifts northward, bringing moist air to the city. The presence of the Sulaiman Mountains to the west also contributes to orographic precipitation, where moist air rises over the mountains and condenses, leading to rainfall on the leeward side. Additionally, Dera Ismail Khan is located in a rain-shadow zone of the Western Ghats, which blocks moisture from reaching the city during the winter months, resulting in the distinct dry season.
Historical Rainfall Patterns
Rainfall in Dera Ismail Khan, Pakistan, has been consistently low throughout history. The city lies in the semi-arid zone of the country, characterized by a dry climate with limited precipitation.

The city experiences occasional heavy rainfall events, but these are rare and usually localized.
Impact on Agriculture and Water Resources
The lack of rainfall in Dera Ismail Khan has significant implications for agriculture, the city’s primary economic activity. The limited water availability restricts crop production and livestock farming, making the region vulnerable to droughts. The city also faces challenges in accessing clean water, with groundwater sources often being depleted. Limited rainfall also affects the replenishment of dams and reservoirs, further exacerbating the water crisis. As a result, the city heavily relies on irrigation systems and water conservation measures to meet its water needs.

Photos and videos of the snowy city went viral on social media, showcasing the rare spectacle.
