The time when water vapor is no longer a constraint on cloud formation, the Monsoon provides for some spectacular visuals. The clouds are mainly formed due to convection over the Indian Ocean, which is why all the normal signatures of cloud formation like thunder and lightning are not very common. It simply pours. The time when thunder and lightning are common is when clouds form locally, during the months of April and May.
This monstrosity is probably many kilometers long. An interesting thing to notice is the base of clouds, which is always nearly flat. The base is probably around 2.5 to 3 kilometers above the earths surface. This marks the top of the atmospheric boundary layer. Clouds this big are always bad news and seem to be cumulus congestus in the picture. This will eventually grow and bear rain. The formless sheets in front seem to be altostratus and normally dont bear rain. It is probably only in this season that you can see cumuli and stratus clouds together.
Some really high clouds were also visible, indicating strong convection somewhere else. Cirrus clouds are normally found at a height of 5-6 kilometers and look very peaceful.
And another shot of cumulus clouds, the smaller variety.
Compare these with the clouds normally seen a few months before. The sky is way busier than in the months preceding the monsoon. Blame it on the winds.
