Blizzards are characteristic features of the Antarctic region. A blizzard is a severe snowstorm with strong winds and reduced visibility. Although blizzards can occur in other regions as well, they are most commonly associated with the Antarctic.

Option 1: The equatorial region is characterized by high temperatures and is not prone to blizzards.

Option 2: The tropical region also experiences high temperatures and typically does not encounter blizzards.

Option 3: The correct answer. The Antarctic region, with its extremely cold temperatures and strong winds, is known for its frequent occurrence of blizzards.

Option 4: The temperate region experiences a range of climates, but blizzards are less common in these areas compared to the Antarctic region.
