Rainfall dynamics has been being one of the least understood topics and has been affecting human civilization since time immemorial. Because of its all-pervading effect on all aspects of the society, starting from the day-to-day living of mankind to agriculture, industry, aviation, weather monitoring, and weather forecast, etc., probably it stands out to be the most significant factor that needs attention. Moreover, change in rainfall pattern all over the world necessitates an investigation of this parameter in-depth.
The tropics play an essential role in regulating the atmospheric heat engine. So, the cloud characteristics in this region demand careful attention and understanding.
In the paper titled “TRMM-retrieved rainfall mechanism over a few tropical locations” presented at the SPIE remote Sensing conference, Strasbourg, France, during 9-12 September 2019, the authors have investigated rainfall and upper air meteorological elements, viz. the cloud liquid water (CLW), the precipitation water (PW) and the latent heat (LH) derived from the data product 2A12 of the Tropical Microwave Imager (TMI) onboard the Tropical Rainfall Measuring Mission (TRMM) satellite over four tropical locations in India, namely Bangalore (12.97N, 77.59E), Bhubaneswar (20.29N, 85.82E), Calcutta (22.57N, 88.36E), and Gadanki (13.45N, 9.16E). The study shows that the rainfall can be predicted with excellent accuracy based on the cloud liquid water (CLW), the precipitation water (PW), and the latent heat (LH). It is further found out from the investigation that though all these parameters can predict rainfall independently, all the elements put together can predict rainfall with greater accuracy. The paper presents functional relationships between rainfall and these parameters. These relationships can be used for quantitative estimation of rainfall in the data-sparse region. The article also highlights the vertical profile of these parameters starting from the Earth’s surface up to 18 km above. The paper describes the characterization technique for convective/stratiform dominance on surface rainfall.
Congratulations to Sharunkumar II-CSE who has been drafted by VB Kanchi Veerans of TNPL, Tamilnadu Premier Cricket League. Sona is proud to be a part of his success and wish him all the best in this tournament and all his future endeavours!
Sona college students from salem, Tamilnadu paraded along with Indian military, Navy, Air force and other Para-military forces at Rajpath New Delhi.
They selected Sona college students were selected in the among lakhs of student-volunteers with the competition for places being so tough.
Two of the NCC students of Sona college of technology ( Top Engineering College in Tamilnadu ), salem, Miss. S. Kavya and Miss.K. J.Sangeetha sri had participated in 71st National Republic Day celebration 2020 held at India Gate to Rajpath in New Delhi. They were selected keeping in view their overall performance for the parade, cultural activities, proficiency to participate in the debate on different social issues, and ability to depict the culture of their state.
They were a part of the prime minister’s rally on Jan 28th 2020,held at Cariappa Parade Ground. They stayed in DG NCC camp site for a month. They got a chance to meet General Manoj Mukund Naravane (COAS), Admiral Karambir Singh (CNS),Air Chief Marshal Rakesh Kumar Singh Bhadauria (CAS),Chief minister of Delhi Mr.Arvind Kejriwal and many more dignitaries there. They witnessed Army day parade on Jan 15 at Cariappa Parade Ground. It was an awesome experience being there for them, representing the state. It was a brand new experience withstanding the cold, having full rehearsals with other directores, bands and the horses. The camp made them feel the unity pervailent in our nation and the competitive nature they had to win. They witnessed the enthralling experience of national glory depiction, where a large crowd was treated to a spectacular parade featuring marching contingents, cultural tableaus, amazing precision flying sequences, dare-devil motorcycle riding by women constables of CRPF and more. It was added with marvellous display of India’s military might, cultural diversity, social and economic progress.
They also had chances to visit the President’s and Prime minister’s home. They were a part of the prime minister’s rally on Jan 28th 2020, held at Cariappa Parade Ground. They marched and saluted our Prime Minister Narendra Modi with dignity. They got chances to celebrate festivals with other directores which increased the level of bonding. Feeling proud on being selected and marched in 71st Republic Day.
