Surprised at the current Mumbai Drizzles ?..there is a reason to be...This could happen more in winter, after a front...Vagaries of the Weather...not any trough, Low or Vortex !

Aside the normal conditions, we got surprise drizzles of various intensity in Mumbai,contrary to expectation, formed due to the extensive humidity contains in the regional atmosphere...

Drizzle is a light liquid precipitation consisting of liquid water drops smaller than those of rain – generally smaller than 0.5 mm (0.02 in) in diameter. Drizzle is normally produced by low stratiform clouds and stratocumulus clouds.

Stratiform cloud may form during a warm front passage due to the steady, continuous rain falling from nimbostratus cloud, adding substantial amounts of humidity to the air

Stratiform precipitation, in general, is relatively continuous and uniform in intensity (i.e., steady rain versus rain showers).

Shallow, stable, non-precipitating cloud. Differs from stratus in that it is broken. Stratocumulus often results from PBL(planetary boundary layer (PBL), also called atmospheric boundary layer, the region of the lower troposphere where Earth's surface strongly influences temperature, moisture, and wind through the turbulent transfer of air mass. The height of the PBL ranges from 100 to 3000 m and varies with time, location, and weather conditions-)based cumulus, that encounters a stable layer and is forced to spread laterally.

Thanks, Rajesh for the detailed explanation .. yes we were surprised at the lingering rain.

27th September Night: The UAC ( shown in 25th post Image), will on September 28,  be over parts of West Bengal, Odisha, and some parts of No...
