An intense hailstorm recently caused massive damage to the crops and fruits in south Kashmir’s Kulgam and Shopian districts.
About Hailstorm:
- Hail is a type of solid rain made up of balls or lumps of ice.
- Storms that produce hail that reaches the ground are known as hailstorms.
- They typically last for no more than 15 minutes but can cause injuries to people and damage buildings, vehicles, and crops.
- They are most common in the midlatitudes.
- Hailstorms can sometimes be accompanied by other severe weather events, such as cyclones and tornadoes.
- Size: The size of hailstones can vary widely, from small pellets less than 1/4 inch in diameter to larger stones measuring several inches in size.
- Conditions for Hailstorms to occur:
- Highly developed Cumulonimbus clouds need to be present. These are the massive anvil or mushroom-shaped clouds that are seen during thunderstorms, which can reach heights of up to 65,000 feet.
- There must be strong currents of air ascending through these clouds. These currents are commonly known as updrafts.
- The clouds will need to contain high concentrations of supercooled liquid water.
- How are Hails formed?
- It begins as a water droplet that is swept up by an updraft inside of a thundercloud.
- Other supercooled water droplets which are already present inside the cloud will adhere to the water droplet’s surface, forming layers of ice around it.
- As the water droplet reaches higher elevations within the cloud, it comes into contact with more and more supercooled particles.
- The hail embryo will grow larger and larger as it reaches higher altitudes in the updraft.
- Finally, it will reach a size and weight where gravity will begin to act on it and pull it down.
- Large hailstones are often characterized by alternating layers of clear and opaque ice, caused by irregular rates of freezing.
Hence only statement 1 is correct.

Hailstorms - Explanation of the Correct Answer
The correct answer is option 'A', which states that only statement 1 is correct. Let's analyze each statement individually to understand why.
Statement 1: Hail is a type of solid rain made up of balls or lumps of ice.
This statement is correct. Hail is a weather phenomenon that occurs during severe thunderstorms. It is formed when there are strong updrafts of air that carry raindrops to high altitudes where the temperature is below freezing. These supercooled water droplets freeze and accumulate layers of ice as they are carried up and down in the storm cloud. As a result, hailstones are formed, which are solid balls or lumps of ice. The size of hailstones can vary greatly, ranging from small pebbles to large golf balls or even tennis balls in extreme cases.
Statement 2: They are found only in the Equatorial regions.
This statement is incorrect. Hailstorms can occur in various regions around the world, not just in the Equatorial regions. Hail is more commonly observed in mid-latitude regions where there is a greater likelihood of strong thunderstorms. These regions include the middle latitudes of North America, Europe, and Asia, as well as parts of South America and Africa. In these areas, the atmospheric conditions are more favorable for the formation of hailstones during severe thunderstorms.
Therefore, based on the analysis of each statement, we can conclude that only statement 1 is correct. Hail is indeed a type of solid rain made up of balls or lumps of ice, but it is not limited to the Equatorial regions.
