Over 18 Feet Thick Cloud Layer

A Times report states that Kolkata has an over 18-feet thick cloud layer in the sky. These cumulonimbus towers are tall vertical clouds that stretch up to 18 km. The weather department's Doppler radar shows that these cloud peaks reach heights of 12 to 18 kilometres into the sky.

Why Does This Happen?

Kolkata pulls in a lot of moisture from the nearby Bay of Bengal. The morning heat mixes with this moisture, and the air rushes upwards. Meteorologists call this process CAPE (Convective Available Potential Energy), and it pushes the clouds up very fast.
