Foundations and Evolution
Established in 1875 under the auspices of the Ministry of Earth Sciences, the IMD emerged in response to the devastation wrought by two cyclones in Kolkata and the Andhra coast. The absence of a robust system to monitor atmospheric parameters necessitated the formation of an institution dedicated to meteorological research and forecasting.
From its nascent beginnings with HF Blanford as the Imperial Meteorological Reporter, the IMD has undergone remarkable transformation. Under the leadership of Gilbert Walker in 1903, the IMD made significant strides in understanding monsoons, laying the groundwork for modern meteorological science. Walker's identification of atmospheric oscillations paved the way for elucidating phenomena like the El Niño effect, expanding the frontiers of meteorological knowledge.
Over the ensuing 150 years, the IMD has burgeoned into a behemoth of meteorological expertise, boasting a network of observatories and automatic weather stations spanning the length and breadth of the nation. Its pivotal role in mitigating the impact of natural disasters, particularly exemplified during the Odisha super cyclone of 1999, underscores its indispensable contribution to public safety and welfare.
Pioneering Initiatives and Technological Advancements
The IMD's commitment to innovation is evident in its pioneering initiatives and technological advancements. From the National Monsoon Mission (NMM) to the Mausam App and Doppler Weather Radars, the IMD has leveraged cutting-edge technology in accordance with the Digital India scheme to enhance forecasting accuracy and accessibility. The Weather Analysis and Forecast Enabling System (WAFES), a web-based decision support system inspired by the elements, empowers stakeholders across diverse sectors with real-time meteorological insights.
The launch of the Panchayat Mausam Seva Portal exemplifies the IMD's commitment to India’s scientific achievements, providing weather forecasts in multiple languages to rural communities. Likewise, the IMD's mobile app, Mausamgram, epitomizes its vision of ubiquitous weather services, empowering citizens with personalized forecasts and warnings.
Organization and Structure
The Indian Meteorological Department (IMD) is overseen by the Director General of Meteorology, currently Mrutyunjay Mohapatra. Under his leadership, the IMD is organized into six Regional Meteorological Centres, each headed by a Deputy Director General, strategically located in Chennai, Guwahati, Kolkata, Mumbai, Nagpur, and New Delhi. Additionally, every state capital hosts a Meteorological Centre. Various specialized units within the IMD, such as Forecasting Offices, Agrometeorological Advisory Service Centers, Hydro-meteorological Offices, Flood Meteorological Offices, Area Cyclone Warning Centers, and Cyclone Warning Centers, are typically situated alongside observatories or meteorological centers.
The IMD manages an extensive network of surface and glacial observatories, Upper Air (high altitude) stations, ozone and radiation observatories, and meteorological radar stations. Complementing these ground-based observations, the IMD utilizes data from India's satellite constellation, including Kalpana-1, Megha-Tropiques, and instruments aboard the IRS series and INSAT series satellites. Data contributed by meteorological instruments installed on Indian merchant navy and Indian Navy vessels further enriches the IMD's network. Notably, the IMD has been a pioneer in implementing a message switching computer system in India, facilitating seamless global data exchange.
Global Recognition and Collaborations
IMD's stature as a regional climate center for South Asia and its collaboration with the United Nations' 'Early Warning for All' program underscore its global relevance and impact. The IMD's contributions extend beyond national borders, with its cyclone forecasts benefiting neighboring countries and fostering regional resilience against natural disasters.
IMD also collaborates with esteemed institutions such as the Indian Institute of Tropical Meteorology, National Centre for Medium Range Weather Forecasting, and the National Institute of Ocean Technology, the IMD continually enhances its capabilities. Moreover, the IMD operates seismic monitoring centers strategically positioned for earthquake monitoring and measurements, underscoring its commitment to comprehensive disaster preparedness and response.
Serving Society: Impact and Outreach
Beyond its core functions of weather forecasting and disaster mitigation, the IMD plays a pivotal role in enhancing agricultural productivity, supporting infrastructure development, and fostering economic growth. By providing tailored weather advisories to farmers and enabling safe aviation through aviation weather monitoring, the IMD enriches lives and livelihoods across diverse sectors. The IMD's contributions to GDP growth and farmers' income underscore its pivotal role in driving sustainable development and fostering resilience in the face of climate variability.
Conclusion
As the India Meteorological Department embarks on its 150th year of service, it stands as a beacon of scientific excellence, innovation, and public service. From humble beginnings to global recognition, the IMD's journey exemplifies the transformative power of meteorological science in safeguarding lives, enhancing resilience, and shaping the future of our planet.
As the nation prepares to celebrate this historic milestone, it pays tribute to the visionaries, scientists, and personnel who have dedicated themselves to the noble cause of meteorological research and forecasting. In an era defined by uncertainty and volatility, the IMD's steadfast commitment to excellence remains a testament to the enduring power of science in advancing the common good. Through its unwavering dedication, the IMD has not only shaped the trajectory of meteorological science but also enriched the lives of millions across the globe.
