Which of the following statements about 'Cavum clouds' recently seen in news is not true?
1
They are exclusively formed by natural weather phenomena and do not require any external interference to occur.
2
The formation involves aircraft flying through a layer of supercooled water droplets, causing the droplets to freeze into ice crystals and precipitate, which creates a large, clear gap.
3
Cavum clouds typically form at altitudes above 20,000 feet where temperatures are below freezing, and water droplets can exist in a supercooled state.
4
Factors such as the cloud layer’s thickness, air temperature, and the degree of horizontal wind shear also play roles in creating these cloud holes.
