There was no significant heat wave spell observed during the month over any parts of India, the IMD said.

Rainfall over the country as a whole for the month of May 2021 shows that it has recorded 107.9 millimetres which is 74 per cent more than its Long Period Average (LPA) of 62 mm.

“Rainfall over India during the month of May was second highest since 1901. The ever highest rainfall occurred in the year 1990 (110.7mm),” the IMD said in its monthly report for May.

May saw formation of a cyclone each in the Arabian Sea and the Bay of Bengal.

Tauktae formed over the Arabian Sea and developed into an ‘extremely severe cyclonic storm’. It hit the Gujarat coast on May 17 after battering states along the western coast.

Cyclone ‘Yaas’ developed over the Bay of Bengal and intensified into a ‘very severe cyclonic storm’. It hit the Odisha coast on May 26 and also affected West Bengal.

These two systems brought rainfall not only over the states along the western and eastern coasts but also to other parts of the country. For instance, as Cyclone ‘Tauktae’ weakened, it headed towards north India and brought rains over several parts of north India.

Similarly, Yaas’ brought rains over east India including Jharkhand, Bihar as it weakened.

The IMD said that in all three months of the summer of 2021, frequencies of western disturbance activities over north India were higher than normal.

In March, April and May 2021, it was seven, nine and eight respectively against normal of 4-6 WDs, the IMD added.

Western disturbances are cyclonic storms that originate in the Mediterranean, traverse across Central Asia and hit the north India. They are critical to northwest India as they are a major source of snow and rainfall during the winters.

Like in March and April 2021, heat wave conditions in May 2021 was occasional and also for shorter periods over very small region.

“No significant heat wave occurred during the month over the country except northwest Rajasthan where it was observed for two days on May 29 and 30, the IMD said.
