Lasers can Trigger Rain formation...?

Scientists made a breakthrough! In their paper published in Nature Communications, they describe a method whereby a laser is used to create nitric acid particles in the air to which moisture will gravitate forming droplets.
Thereby triggering the formation of Rain.

 Field measurements suggest the mechanism of laser-assisted water condensation, Nature Communications 2, Article number: 456doi:10.1038/ncomms1462

Lunar Eclipse (Real fotos & Simulation)

Image
My colleague Mr.Sobhan Kumar Kompalli, Scientist in Space Physics Laboratory has clicked more than 100 snaps of the beautiful 'Lunar Eclipse' that entertained earthlings on 10-Dec-2011. Here is a matrix of few selected snaps by the  amateur  photographer. Also have a view of the Simulated Lunar Eclipse ( animation)  which I generated using the open source software 'Stellarium'. You are welcome to watch  the drama unfold......! Photograph by Mr.Sobhan Kumar Kompalli (sobhan1urs@gmail.com)

Descending Cirrus clouds characteristics over Gadanki (Tirupati, Andhra Pradesh). Our research published

Image
Our long awaited publication exploring the Descending Cirrus clouds over Gadanki. Int'l. Journal of Remote Sensing It is the story of Cirrus clouds which descends / ascends altitude ..... their characteristic properties ....using NARL's long term Lidar data. Nellore Manoj Kumar, Kannan Venkatramanan, Anish Kumar M. Nair & Shekatam Satheesh Kumar   (2020)   On the characterization of descending nature of cirrus clouds over a tropical site, Gadanki,   International Journal of Remote Sensing,   41:17,   6550-6569,   DOI:  10.1080/01431161.2020.1742942 https://t.co/vpReYZZZsY https://t.co/3zJDq2KNjM https://www.tandfonline.com/doi/abs/10.1080/01431161.2020.1742942 The interesting feature of Cirrus cloud's descending & ascending are well characterized using ~6 years of lidar observations. The study roots back to the inspiration from my earlier work published in J.Geophysicsl Research in 2012 Nair,  A. K. M.   ,  K. Rajeev ,  M. K. Mishra ,  B. V. Tham

Solar Eclipse over Tirupati 09 Mar 2016 (simulated)

Image
Solar Eclipse (09 Mar 2016) is hardly visible over Tirupati. Here is an animated version (Figure (a)) of the simulation I have prepared using the free open source "Stellarium" software. The Sun rises over Tirupati by 06:23 IST. Meanwhile eclipse has already begun and being in penumbra region, it's partial eclipse over here. Click here to see the eclipse For reference, the figure (b) of eclipse locations are shown in the figure below (scroll down) which also shows time in Tirupati during the events.  (courtesy: timeanddate.com ) Figure (a): Animation of the solar eclipse (simulated) over Tirupati. 'E' indicates East Figure (b): How eclipse happens world wide (courtesy: timeanddate.com)
