IMD’s report on depression over Arabian Sea during 29th May to 1st June
The Depression was monitored with the help of available satellite observations from INSAT 3D and 3DR, polar orbiting satellites including SCATSAT, ASCAT etc. and available ships & buoy observations in the region
The National Weather Forecasting Centre/Regional Meteorological Centre, New Delhi of the India Meteorological Department  has released a report on depression over Arabian Sea during 29th May to 1st June. Some of the salient features of the report are discussed below:
Brief Life History:
- A cyclonic circulation developed over westcentral and adjoining southwest Arabian Sea  on 27th May. Under it’s influence, a low pressure area formed over westcentral AS in the morning  of 28th May.
- It lay as a Well Marked Low pressure area  over westcentral AS off south Oman-east Yemen coasts in the morning  of 29th May.
- Under favourable environmental conditions, it concentrated into a depression  over south coastal Oman and adjoining Yemen in the afternoon  of 29th May.
- It moved slightly westwards till the morning  of 30th May over south coastal Oman and adjoining Yemen.
- Thereafter, it moved southwestwards and weakened into a WML over south coastal Oman and adjoining Yemen in the early morning  of 1st June 2020.
The IMD maintained round the clock watch over the north Indian Ocean and the system was monitored since 27th May with the development of cyclonic circulation over westcentral and adjoining southwest AS.
The Depression was monitored with the help of available satellite observations from INSAT 3D and 3DR, polar orbiting satellites including SCATSAT, ASCAT etc. and available ships & buoy observations in the region. Various numerical weather prediction models run by the Ministry of Earth Sciences  institutions, various global models and IMD’s dynamical-statistical models developed in-house were utilized to predict the genesis, track, landfall and intensity of the Depression. A digitized forecasting system of IMD was utilized for analysis and comparison of various Numerical models’ guidance, decision making process and warning product generation.
India Meteorological Department  and RSMC New Delhi duly acknowledge the contribution from WMO and all the stake holders and disaster management agencies who contributed to the successful monitoring, prediction and early warning service of depression over south coastal Oman and adjoining Yemen. We acknowledge the contribution of all sister organisations of Ministry of Earth Sciences including National Centre for Medium Range Weather Forecasting Centre , Indian National Centre for Ocean Information Services , National Institute of Ocean Technology , Indian Institute of Tropical Meteorology  Pune, research institutes including IIT Bhubaneswar, IIT Delhi and Space Application Centre, Indian Space Research Organisation  for their valuable support. The support from various Divisions/Sections of IMD including Area Cyclone Warning Centre  Chennai and Mumbai Cyclone Warning Centre  Thiruvananthapuram, Ahmedabad and Meteorological Centre  Goa. The contribution from Numerical Weather Prediction Division, Satellite and Radar Division, Surface & Upper air instruments Divisions, New Delhi and Information System and Services Division at IMD is also duly acknowledged.
