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)

Don't miss to watch the 'Transit of Venus'

Image
Be prepared to watch a heavenly drama on 6 June 2012. The Venus can be seen as a black dot travelling across the Solar Disk. Here is my Simulation: Yes, it is the "Transit of Venus across the Sun" Path-- L to R Credit: Michael Zeiler, eclipse-maps.com India comes under the visibility of the event after Sunrise. See the graphic below: Thiruvananthapuram can view it right from sunrise to 10:22 AM. The graphic was prepared using the tool provided in  http://transitofvenus.nl/wp/where-when/local-transit-times/   You can change the location and see about your visibility to the drama. Also read the following blog for wonderful information and graphics. http://blogs.esa.int/venustransit/        (nice and informative blog by ESA) http://eclipse-maps.com/Eclipse-Maps/Transits.html     (Transit maps) http://sunearthday.nasa.gov/transitofvenus/ You can also find how to watch the event.... Follow safe way.... take care ...

Modelling getting better .....

Clouds and aerosol particles have bedevilled climate modellers for decades. Now researchers are starting to gain the upper hand. Researchers say they are beginning to turn a corner in simulating clouds and aerosols. In recent months, climate scientists have started rolling out initial results from the newest generation of models, which represent atmospheric chemistry and microphysics in much more sophisticated ways than previous incarnations. These models allow clouds and aerosols to evolve as they interact with each other and respond to factors such as temperature, relative humidity and air currents.  Read more : http://www.nature.com/news/climate-forecasting-a-break-in-the-clouds-1.10593 Nature International weekly journal of science Go Advanced search
