• For its unusual wedge-shaped structure, Arcus Cloud is well-known.
• It often occurs on the front edge of a storm and extends horizontally beneath the primary cloud base.
• When a mass of cold, dense air is driven by the wind into a warmer air mass, shelf clouds are formed.
• This occurrence occurs when cold air swiftly descends and dissipates during a thunderstorm’s downdraft, producing a powerful gust front.

What are the different types of cloud?

   • Formation: Large quantities of warm, humid air ascend, forcing water vapour to condense, resulting in the formation of altostratus clouds.
   • Warm fronts are typically predicted by altostratus clouds.
2. Altocumulus
   • Clouds having globe shaped masses or can be viewed as rolls in layers.
   • Globes found to be darker than the the layer in a greyish sheet. 

C. Low Clouds

• Altitude: 2500 metres
• Also called as Stratus Clouds.
• Formation: Dense, dark, and rainy (or snowy)
• It is viewed as hump on a blue sky.

1. Strato Cumulus
   • Formation: Large dark, rounded or globular masses, usually in groups, lines, or waves.
2. Stratus
   • Low-level stratus clouds have a largely uniform grey or white tint.
   • Near the coast, stratus clouds form dense cloud cover.
3. Nimbostratus
   • Formation: Dark, Thick 
   • They forms precipitations, continous rain or snow.
