These
monsoons will be dealt with in the pages to follow, till then a drizzle of
explanation will suffice,
The term
Monsoon comes from the Arabic “Mausim”, which means seasonal weather or wind
shift.
During the Northern summer the continent of Asia gets
very warm resulting in low pressure over it. The lowest recorded so far, being
about 996 mb ( millibar)over the North West India. This low being considerably
lower than the equatorial low of 1012 mb and, hence the pressure gradient
exists from the equator towards North West India. The South East Trade winds
blowing from oceanic high of the 30 degrees South Latitude towards the equatorial low and cross over the
equator and blow as a strong South west wind called South West monsoon towards
the low over NW India.
The period
of the year of SW Monsoon the India Ocean – Arabian sea is
from about June to September.
