The moody South-West monsoon that has threatened to hit the farming season could be attributed to inadequate number of cyclonic systems over the Bay of Bengal.

This monsoon, the State has received 613.1-mm rain between June 1 and August 8 recording a deficit of six per cent which is normal by meteorological standards. It was only in the last week that the State received copious showers, 31 pc excess rain.

The overall monsoon rains may appear normal for Odisha. It is not just Odisha which is at the receiving end of the monsoon, the country as a whole has been reeling under a patchy rainfall situation.

The Indian Meteorological Department has attributed the situation to a lower frequency of cyclonic weather systems, such as low pressures and depressions, over the Bay of Bengal as well as the Arabian Sea. The low pressures and depressions are the principal rain-bearing systems.

As against the average frequency of about six or seven such systems during the current season, only one low pressure has formed so far. The declining number of systems, the IMD said, is the culprit for the deficit rainfall over the country.
