Activity ceased for approximately 2 months before Depression ARB 01 was designated and struggled against strong wind shear and dry air intrusions.
After Sitrang, Depression BOB 08 formed and struggled to consolidate a well-defined center before causing minor impacts to parts of southern India.
Despite moderate easterly mid-level wind shear, Mandous intensified to a Severe Cyclonic Storm as it neared Sri Lanka.
Additionally, sea surface temperatures (SST) of 27–28 °C (81–82 °F) were warm enough for tropical cyclogenesis to take place, along with moderate to high vertical wind shear.
[12] After maintaining its intensity for a day, the JTWC issued its last warning for the system, at 15:00 UTC (20:30 IST) as the increasing dry air had weakened its convective mass.
[14] On 6 March, the IMD issued its last advisory for the system and downgraded it to a well-marked low pressure area, as its convective mass got further disorganized by the wind shear.
[19] The system gradually intensified, into a deep depression by 00:00 UTC (05:30 IST) the next day,[20] as the convection had further organized favorable conditions such as moderate to high sea-surface temperatures.
At the same time, a Westerly wind burst occurred on the same day which resulted in formation of twin cyclones over the either side of the Indian Ocean.
[29] Subsequently, the JTWC issued its TCFA, as it had rapidly consolidated its convective structure for the past few hours, along with development of a well-defined low-level center.
[31] At 09:00 UTC (14:30 IST), the JTWC initiated advisories on the system and classified it as Tropical Cyclone 02B, while IMD followed the suit and upgraded it to Depression BOB 03.
[32][33] Three hours later, the system was further upgraded to a deep depression status by the IMD, after forming a defined central dense overcast cloud pattern.
[40][41] it began to make a sudden westward jog and mild decrease in wind shear made the JTWC to upgrade it again into a Category 1-equivalent tropical cyclone.
[42] Nine hours later, Asani was further downgraded into a tropical storm, it began to weaken rapidly due to higher wind shear as well as dry air intrusion.
[46] By 00:30 UTC (06:00 IST) the JTWC published its TCFA for the system after it had rapidly consolidated its convective structure for the past few hours, and also formed a well-defined low-level center.
[48] However, according to IMD, it rapidly consolidated into a well-marked low pressure area in the morning of the same day, and further into a depression at 11:30 IST (03:00 UTC), as it moved northeastwards, towards the south Burmese coast.
[56] It peaked as a depression, with maximum sustained wind speed of 25 kn (45 km/h; 30 mph) and a minimum barometric pressure of 992 hPa (29.29 inHg) after its initial stage of formation.
[61] It managed to maintain its intensity overland, until at 00:00 UTC (05:30 IST) of 10 August, it was downgraded to a remnant low over Chhattisgarh and adjoining east Madhya Pradesh.
[74] Brown ocean effect played a major role in the system's lifetime, as it managed to maintain its depression status over land for three days.
[76][77][78] On 17 August, the JTWC recognized a newly formed low level circulation near Myanmar and designated it Invest 99B, which showed disorganized convective structure and an obscure low-level center.
[87][88] The system persisted for another two days until 23 August, when it weakened into a well-marked low pressure area over eastern Rajasthan and adjoining northwestern Madhya Pradesh.
[90][91][92][93][94][95] The depression's influence brought extremely heavy rainfall across east and central India over a period of several days, dropping up to 23 cm (9.1 in) of precipitation over Bhograi on 20 August.
The low developed over the next several days under favourable conditions, eventually organizing into a depression over southern Odisha by 00:00 UTC on 11 September.
[99] Days later, warm waters and less wind shear contributed to favorable conditions for development, and the IMD classified the low pressure area as a depression, being called BOB 07, according to the third bulletin.
[103] Upon making landfall near Patuakhali, Bangladesh, in the early hours of 24 October, the cyclone began to lose strength and was downgraded to a deep depression.
[104] Afterwards, Sitrang continued to weaken, and in its thirteenth and final bulletin, the IMD declared that the cyclone was downgraded to a low pressure area by 06:00 UTC of 25 October.
[110] On 15 November, the IMD noted that a low-pressure area could form over the Bay of Bengal and develop into a depression over the next several days as it moved west-northwestwards.
[111] By 17 November, a low-pressure area developed over the southeastern Bay of Bengal under the influence of a mid-level cyclonic circulation situated over the southern Andaman Sea.
[118] The JTWC, released a TCFA on the system, stating that it could intensify further, because of very warm waters and low to moderate wind shear, designating it Invest 96B.
Although forecasted to quickly degenerate into a remnant low, ARB 03 intensified into a Deep Depression, according to the Indian Meteorological Department,[132] and the JTWC dubbed it as Cyclone 07A.
After reaching peak intensity, the Low-Level Circulation detached from the associated convection as dry air and wind shear increased, starting a weakening trend.
