Cyclone Fani: A rare one to hit Indian shores

Cyclone Fani: A rare one to hit Indian shores

Cyclone Fani, one of the biggest storms in years to make landfall in India, slammed the city of Puri in Odisha with winds raging up to 200 kmph on Friday. Though, in terms of maximum windspeed, Fani is only the seventh highest among cyclones to have originated from the Northern Indian Ocean since the 2000s, very rarely do such cyclones which were formed in the month of April over the Bay of Bengal go on to make landfall in India. This makes Fani a unique case of a cyclone that originated in April.

The following image shows the path of all severe cyclones ( maximum wind speed of >47 knots) to have originated in the month of April over the Bay of Bengal between 1891 and 2017.

Cyclone Fani: a rare one to hit Indian shores

As can been seen from the image, only once before, April 1966 to be precise, did such a severe cyclone hit the Indian mainland.

A rarity

April is an unusual month for a cyclone in India. Of the 1,528 recorded depressions/cyclonic storms/severe cyclones over the North Indian Ocean since 1891, only 45 (3%) occurred in the month of April. Thats the fifth least among all months after July, February, March and January.

Table shows depressions (maximum wind speed between 17 and 33 knots) / cyclonic storms (between 34 and 47 knots) / severe cyclones (>47 knots) occurred between 1891 and 2019 over the North Indian Ocean.

cyclone tableObservations from the table

1. Depressions (those which does not get converted to bigger cyclones) are lowest at the start of a year and gradually increase and peak at August before dropping again in number terms.

2. But, cyclonic storms and severe cyclones follow a slightly different pattern. Their numbers first peak in May and then dip only to peak again in October-November.

Interestingly, the probability of a depression getting converted into a Cyclonic Storm/ Severe Cyclone is very high in April. 44% of all storms in April were Severe Cyclones, a number that is less only than the number for the month of May (48%).

Table shows the share of recorded depressions/cyclonic storms/severe cyclones in various months between 1891 and 2019

How big is Fani?

The Indian Meteorological Department had issued a warning that the Cyclone Fani will reach the Odisha coast on Friday afternoon with maximum speed of 170-180 kmph going up to 200 kmph or 108 knots. How does this maximum speed compares to other cyclones since 2000 in the North Indian Ocean?

In the 178 depressions/cyclonic storms/severe cyclones recorded since 2000, Fani’s Maximum Sustained Surface Wind of 108 knots was the seventh highest.

Image result for fani

When only the month of April is considered, Fani’s maximum speed is the highest recorded since the 2000s,  closely followed by Cyclone Mala which was formed over Bay of Bengal and proceeded to make landfall in Myanmar in 2006.  Table shows the top 25 cyclones in terms of maximum wind speeds recorded since 2000.

cyclone table 3

It does not necessarily mean that higher the wind speed, the damage would be higher. Some of the cyclones listed never made landfall in India or had weakened before the event.

India test fires exo-atmospheric ballistic missile

India tests exo-atmospheric ballistic missile interception

India on Saturday successfully test-fired its interceptor missile off the Odisha coast.The interceptor was launched from Abdul Kalam Island (Wheeler Island) of ITR at about 7.45 am.

India tests exo-atmospheric ballistic missile interception - Know all about it

India on Saturday successfully test-fired its interceptor missile off the Odisha coast.

The interceptor was launched from Abdul Kalam Island (Wheeler Island) of ITR at about 7.45 am.

With this, India has achieved a significant milestone in the direction of developing a two-layered Ballistic Missile Defence system.

This mission, termed as “PDV mission” is “for engaging the targets in the exo-atmosphere region at an altitude above 50 km of earth’s atmosphere”, said a Defence Research Development Organisation (DRDO) official.

“Both, the PDV interceptor and the two stage target missile, were successfully engaged,” he said.

The target was developed for mimicking a hostile Ballistic Missile approaching from more than 2,000 km away and was launched from a ship anchored in the Bay of Bengal.

In an automated operation, radar-based detection and tracking system detected and tracked the enemy’s ballistic missile.

The computer network with the help of data received from radars predicted the trajectory of the incoming Ballistic Missile.

PDV, that was kept fully ready, took off once the computer system gave the necessary command for lift-off. The Interceptor guided by high accuracy Inertial Navigation System (INS) supported by a Redundant Micro Navigation System moved towards the estimated point of the interception.

Once the missile crossed the atmosphere, the Heat Shield ejected and the IR Seeker dome opened to look at the Target location as designated by the Mission Computer.

The interceptor is based on the nuclear-capable Prithvi Missile.

With the help of Inertial Guidance and IR Seeker the missile moved for the interception. All events were monitored in real-time by the Telemetry/Range Stations, at various other locations.

Parrikar undertakes an aerial survey to trace IAF AN-32

No trace of missing IAF AN-32 plane as yet; Defence Minister Parrikar undertakes aerial survey

No trace of missing IAF AN-32 plane as yet; Defence Minister undertakes aerial survey

Search operations continued on Saturday for an Indian Air Force plane that went missing in the Bay of Bengal on Friday.

The IAF AN-32 “courier flight” with 29 people on board was flying from the Tambaram air base near Chennai to Port Blair in the Andaman and Nicobar Islands when it vanished from radar at 9.12 am.

The plane was 280 kilometres east of Chennai when it fell off the radar.

As per reports, more than 12 Navy and Coast Guard ships carried on the search operation through the night in their respective search areas.

A P8I, one CGDO and a C130 have also been deployed in the area for the search operations, ANI reported.

Defence Minister Manohar Parrikar also arrived in Chennai today to monitor the search operations for the missing aircraft.

Upon his arrival, he boarded an aircraft from Tambaram for an aerial survey of the search operations.

“All efforts are being made to trace the missing plane and the service personnel on board,” Parrikar had said yesterday.

Among the 29 people on board the transport aircraft were six crew members and eight civilians (family members of IAF personnel). Others on board included 11 IAF personnel, one Navy and two Army soldiers and a coast guard member, NDTV reported.

It is suspected that the plane plunged rapidly from an altitude of 23,000 feet.

The last call from the pilots was received around 16 minutes after take-off. The pilots had then said, “everything is normal”.

A naval submarine, which is part of the search team, will be looking to track the signal from the emergency beacon locator on the aircraft which gets activated in case of a crash.

The Indian Air Force currently has more than 100 Russian-made AN-32s in service.

Indo-Myanmar Coordinated Patrol (IMCOR) and Signing of Standard Operating Procedure (SOP)

Indo-Myanmar Coordinated Patrol (IMCOR) and Signing of Standard Operating Procedure (SOP)

               As part of the ongoing India-Myanmar defence relations, Navies of the two countries have conducted Coordinated Patrols along the Maritime boundary since 2013. Taking it forward, the Fourth Edition of the India-Myanmar Coordinated Patrol (IMCOR) was successfully undertaken from February 13 to 16, 2016 along the International Maritime Boundary Line (IMBL) in the Andaman Sea. Indian Navy Ships Saryu and Bitra along with Union of Myanmar Ships Aung Zeya and FAC 563 participated in the 4th IMCOR. Cmde Girish Garg, Naval Component Commander from the Tri-Service HQs in Port Blair was embarked onboard INS Saryu.

             During the Closing Ceremony of 4th IMCOR, the Standard Operating Procedure (SOP) for IMCOR was also signed between Indian Navy and Myanmar Navy. Cmde Atul Anand VSM from Indian Navy and Cmde Aung Zaw Hlaing from Myanmar Navy signed the document in the presence of H.E Gautam Mukhopadhaya, the Ambassador of India to Myanmar. This is only the third country with which India has signed a formal agreement for maritime coordinated patrols and reflects growing naval interaction between India and Myanmar. The signing of the SOP is a significant achievement and will facilitate smooth conduct of coordinated patrols between two friendly neighbours that share a long maritime boundary in the strategically significant Andaman Sea and Bay of Bengal.
