Abstract:
Of all the natural conditions, rainfall should be regarded as fundamental
as far as progress of the society is concerned. In met, it is has always been treated as a
fundamental sector for the total development of the society. India is a tropical country
and its agricultural planning and utilization of water depends on monsoon rainfall, with
more than 75% of rainfall accruing during the monsoon season. The monsoon rainfall is
unevenly distributed both in time and space, so it is an important factor in evolving
rainfall analysis. Cuddalore District situated south of Palar River, and one of the
northern districts of Tamil Nadu, covers an area of 3,564 km2. This district lies between
11°5' and 12°30' N latitudes, and 78° and 80° E longitudes and is bounded by the Bay
of Bengal to its east, by Nagapattinam District to its south, and by Perambalur District
to its west The present study endeavours to clearly comprehend the rainfall variability
in both coastal and interior parts of Cuddalore District, and examine the impact of
variability on life.
