The correct answer is 1, 2, and 3.
Important Point
- Western Disturbances
- The western cyclonic disturbances are weather phenomena of the winter months brought in by the westerly flow from the Mediterranean region. Hence, statement 1 is correct.
- Western Disturbances develop in the mid-latitude region (north of the Tropic of Cancer), not in the tropical region; therefore, they are called mid-latitude storms or extra-tropical storms. Hence, statement 2 is correct.
- Extra-Tropical Cyclones are also called winter storms and blizzards.
- A high-pressure area over Ukraine and neighborhood consolidates, causing the intrusion of cold air from Polar Regions towards an area of relatively warmer air with high moisture.
- This generates favorable conditions for cyclogenesis in the upper atmosphere, which promotes the formation of an eastward-moving extratropical depression.
- They gradually travel across the middle-east from Iran, Afghanistan, and Pakistan to enter the Indian sub-continent.
Key-Points
- Impact of Western disturbance
- Western disturbances play an important role in bringing moderate to heavy rain in low-lying areas and heavy snow to mountainous areas of the Indian Subcontinent.
- This disturbance is usually associated with a cloudy sky, higher night temperatures, and unusual rain. Hence, statement 3 is correct.
- Precipitation during the winter season has great importance in agriculture, particularly for rabi crops, including wheat, which is one of the most important Indian crops.
- During the monsoon season, western disturbances may occasionally cause dense clouding and heavy precipitation.
- Strong western disturbances can help residents, farmers, and governments avoid many of the problems associated with water scarcity.
- Weak western disturbances are associated with crop failure and water problems across north India.

Western Disturbance
The Western Disturbance is a weather phenomenon that affects the Indian subcontinent during the winter months. It is brought in by the westerly flow from the Mediterranean region and is characterized by the presence of cyclonic disturbances. Let's examine each statement in detail to determine their correctness.
Statement 1: The western cyclonic disturbances are weather phenomena of the winter months brought in by the westerly flow from the Mediterranean region.
This statement is correct. Western Disturbances are weather systems that originate in the Mediterranean region and move eastwards towards the Indian subcontinent. They are most active during the winter months, particularly from December to February.
Statement 2: These storms are extra-tropic cyclones.
This statement is correct. Western Disturbances are extra-tropical cyclones that form outside the tropics, usually around 30-60 degrees latitude. They are associated with the polar front jet stream which helps in their formation and movement.
Statement 3: This disturbance is usually associated with a cloudy sky, higher night temperatures, and unusual rain.
This statement is correct. Western Disturbances are typically associated with changes in weather patterns such as cloudy skies, higher night temperatures, and precipitation in the form of rain or snow. As these disturbances move across the Indian subcontinent, they bring moisture and instability, leading to cloudy conditions and precipitation.
Conclusion:
All three statements are correct. The Western Disturbance is a weather phenomenon of the winter months, originating from the Mediterranean region and characterized by extra-tropical cyclones. It is associated with cloudy skies, higher night temperatures, and unusual rain in the affected regions. Understanding the behavior and impact of Western Disturbances is important for weather forecasting and planning in the affected areas.
