Question

Which of the following clouds are present at higher altitude?

• B. Cumulus
• C. Startus
• D. Nimbus

Answer 1

The correct option is A

Cirrus

High Clouds are mainly cirrus (Ci) of feathery form at 20- 40,000 feet above ground.

1. Cirrus (Ci) This looks fibrous and appears like wisps in the blue sky; it is often called 'mares tails'. It indicates fair weather, and often gives a brilliant sunset.

2. Cirrocumulus (Cc): This appears as white globular masses, forming ripples in a 'mackerel sky'.

3. Cirrostratus (Cs):- This resembles a thin white sheet or veil; the sky looks milky and the sun or moon shines through it with a characteristic 'halo'.
