Enigma of the summer monsoons

Here's an enigma of the swamp:

Why aren't our summer rains called monsoons?


F
lorida's summer has diurnally shifting
daytime (sea) and nighttime (land) breezes

After all, the American Southwest and Himalayan-hugging Indian peninsula have similarly distinct cycle of rainy summer and a dry winter spans.

Why then the humdrumly named “wet season” for south Florida while the other two other get provocatively dubbed as a “monsoon season” instead?


T
he summer wind on the Indian Peninsula
blows doesn't shift day and night but rather
blows continually inland

Answer: A low-level sea breeze feeds our summer downpours. It switches back and forth on a diurnal basis from a low-lying inland-blowing seas breeze by day to a coastward-blowing land breeze by night. Once the upper atmospheric low sets in place over the Indian peninsula it rules the sky all summer long. Or in other words – both day and night ...

The Indian sea breeze blows uninterrupted inland all summer long.
