Indian Navy unveils Integrated Automatic Aviation Meteorological System at Rajali Air Station

The Indian Navy has unveiled the Integrated Automatic Aviation Meteorological System (IAAMS) at Rajali Air Station in Tamil Nadu.

The aim of IAAMS is to modernise the meteorological infrastructure of the nine Naval Air Stations (NAS). It is expected to bring accuracy in weather monitoring mechanism in the Indian Navy.

Key Facts
  • IAAMS is equipped with the state-of-the-art meteorological sensors viz., Radar Vertical Wind Profiler, Ceilometer, Transmissometer and Automatic Weather Observation System.
  • It undertakes automatic and continuous recording of relevant weather parameters that are vital for accurate weather forecasting.
  • It has a special alarm feature that alerts the duty staff during abnormal change of weather parameters that may affect safe flying operations.
  • It can also provide automatic dissemination of routine weather reports as per standards of World Meteorological Organisation (WMO) to other air stations and Air Traffic Controller towers without human intervention.
Background

The IAAMS is an ambitious project of the Indian Navy to modernise the meteorological infrastructure of the nine Naval Air Stations (NAS). Installation of the system at remaining eight stations is expected to be completed by March 2019. After completion, the project will give a major fillip to aviation safety, through automation of weather monitoring process.

March 23: World Meteorological Day

The World Meteorological Day (WMD) is observed every year on 23rd March to mark establishment of World Meteorological Organization (WMO) on this day in 1950.

2017 Theme:Understanding Clouds”. It seeks to highlight the enormous importance of clouds for weather climate and water. They play a critical role in the water cycle and shaping the global distribution of water resources. Clouds are central to weather observations and forecasts. Clouds are one of the key uncertainties in the study of climate change.

On this occasion, World Meteorological Organisation (WMO) launched new edition of the International Cloud Atlas. It is a treasure trove of hundreds of images of clouds, including a few newly classified cloud types and is single authoritative and most comprehensive reference for identifying clouds. It also features other meteorological phenomena such as rainbows, halos, snow devils and hailstones.  This Atlas for the first time has been produced in a digital format and is accessible via both computers and mobile devices.

Background

On this day in 1950 the World Meteorological Organisation (WMO) Convention came into force that aimed at creating WMO. Later in 1951, WMO became United Nations specialized agency for meteorology, geophysical sciences and operational hydrology. 

About World Meteorological Organization (WMO)

  • WMO is an intergovernmental organization whose mandate covers weather, climate and water resources. It is UN specialized agency for meteorology, operational hydrology and related geophysical sciences
  • It is dedicated to international cooperation and coordination on state and behaviour of Earth’s atmosphere, its interaction with land and oceans, the weather and climate and distribution of water resources.
  • It has 191 Member States and Territories. It originated from the International Meteorological Organization (IMO), which was founded in 1873. It has its headquarters in Geneva, Switzerland.

Renowned Meteorologist Dev Raj Sikka passes away

Renowned Meteorologist and former director of the Indian Institute of Tropical Meteorology (Pune) Dev Raj Sikka passed away. He was 85.

He is famously known as Monsoon Man and the Father of Indian Meteorology. He was first proposed a link between the El Nino phenomenon and the Indian monsoon in 1982, but that time less importance was given to it.

About Dev Raj Sikka

  • He was born on March 1, 1932 in Jhang, Maghiana in Pre-partition India (now in Panjab, Pakistan) and later migrated to India after the partition.
  • He had completed his Masters in Science (MSc) in Physical Chemistry from Agra University and joined Indian Meteorological Department (IMP) in 1954.
  • He joined Indian Institute of Tropical Meteorology (IITM) in Pune in 1964 and retired from the same as the director of the institute.
  • He is credited with being among the pioneers of developing weather models and computer-modelling techniques to forecast the monsoon.
  • He had actively participated in research and development of Monsoon Dynamics, , Prediction of Weather and Climatology, Tropical Meteorology, Atmospheric Chemistry and Air-Sea interaction.
  • He had served as Chairman of the Ministry of Earth Sciences’ Monsoon Mission, a programme to improve monsoon-related forecasts.
  • He also had served as chairman of Council for Scientific and Industrial Research (CSIR) committee on Climate Change and also of Research and Advisory Council of National Centre for Medium Range Weather Forecast.
  • Awards and Honours: IMD’s Lifetime time achievement award and Sir Gilbert Walker Gold Medal (2010). 

About El Nino Southern Oscillation (ENSO)

It is complex climatic and weather phenomenon observed due see-sawing of temperatures in the equatorial Pacific. It is among the most significant factors that meteorologists scan to forecast the performance of the Indian monsoon. 6 out of 10 El Nino-years have been associated with below-normal rainfall over India.
