1964 North Indian Ocean cyclone season

The 1964 North Indian Ocean cyclone season had no bounds, but cyclones tend to form between April and December, with peaks in May and November. The season has no official bounds but cyclones tend to form between April and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. There are two main seas in the North Indian Ocean—the Bay of Bengal to the east of the Indian subcontinent and the Arabian Sea to the west of India. The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center releases unofficial advisories. An average of four to six storms form in the North Indian Ocean every season with peaks in May and November.[1] Cyclones occurring between the meridians 45°E and 100°E are included in the season by the IMD.[2]

Systems

Cyclonic Storm One
Cyclonic storm (IMD)
 
DurationMay 6 – May 9
Peak intensity75 km/h (45 mph) (3-min)  992 hPa (mbar)

Cyclonic Storm One developed in the Bay of Bengal on May 6. It moved east-northeastward and eventually curved northeastward. The system made landfall in Burma before dissipating on May 9.[3]

Very Severe Cyclonic Storm Two

DurationJune 9 – June 13
Peak intensity140 km/h (85 mph) (3-min)  969 hPa (mbar)

Under the influence of the ongoing onset of the southwest monsoon, a trough of low pressure developed over the Arabian Sea off the coast of Karnataka on June 6. It slowly moved northwards, and consolidated into a depression by the morning of June 9. The next morning, while the storm was moving northwestwards, the India Meteorological Department upgraded it to a Cyclonic Storm. Over the following days the storm intensified further into a very severe cyclonic storm, recurved northeastwards and crossed the coast of Gujarat near Naliya at a peak intensity of 969 hPa (28.61 inHg). The system rapidly degenerated inland and dissipated into a low pressure area on June 13. 27 deaths were reported due to the cyclone in India.[4] Prolonged rains associated with the system triggered severe flooding in Pakistan that killed 450 people. Approximately 400,000 were affected by the floods and damage amounted to $4.1 million.[5]

Deep Depression Three

DurationJuly 3 – July 6
Peak intensity55 km/h (35 mph) (3-min)  987 hPa (mbar)

A deep depression developed in the northern Bay of Bengal on July 3. It headed northwestward and soon struck the state of West Bengal in India. The storm persisted for a few days inland, before dissipating on July 6.[6]

Deep Depression Four

DurationAugust 5 – August 6
Peak intensity65 km/h (40 mph) (3-min)  990 hPa (mbar)

Deep Depression Four developed in the northern Bay of Bengal on August 5. It moved westward and struck India before dissipating on August 6.[7]

Cyclonic Storm Five
Cyclonic storm (IMD)
 
DurationAugust 6 – August 7

Deep Depression Six developed in the northern Bay of Bengal on August 10. It later struck eastern India. The deep depression dissipated by August 12.[9]

Depression Seven
Depression (IMD)
 
DurationAugust 15 – August 16
Peak intensity55 km/h (35 mph) (3-min)  995 hPa (mbar)

Depression Seven developed in the Bay of Bengal on August 15 and soon made landfall in India. The depression dissipated on the following day.[10]

Main article: 1964 Rameswaram cyclone

On December 15, an area of low pressure was identified over the southern Andaman Sea. Remaining nearly stationary,[20] it gradually developed into a depression two days later.[21] Despite being at a low latitude of 5°N, favorable conditions allowed the system to steadily strengthen, attaining hurricane-force winds by December 19.[20] Spanning approximately 965 km (600 mi), the cyclone reached its peak intensity on December 21 as it approached Ceylon.[21] Based on satellite imagery, it was estimated that the storm had peak winds of 240 km/h (150 mph), with gusts as high as 280 km/h (175 mph).[21] This ranked the system as a modern-day super cyclonic storm.[22] Weakening somewhat, the system continued westward, moving over Tamil Nadu, before rapidly weakening. The system degenerated into a remnant low after emerging over the Arabian Sea on December 24 and dissipated two days later.[20]

Striking Ceylon as a super cyclonic storm, the storm wrought tremendous damage. Winds well in excess of hurricane-force battered the region for over six hours, destroying more than 5,000 homes.[20][23] In eastern Rameswaram, a passenger train carrying 115 people was swept away by a 4.6 m (15 ft) surge, killing all on board.[23] Nearly every structure in Dhanushkodi was destroyed.[20] Press reports indicated that as many as 2,000 people died on Ceylon, including 350 fishermen offshore. In Tamil Nadu, an estimated 500 people were killed. Damage from the storm amounted to $150 million.[23]
