Ozone and UV bulletin
The stratosphere ozone layer is slowly recovering and the recovery will be complete in most parts of the atmosphere in the coming decades, according to the latest bulletin by the World Meteorological Organization

High concentrations of ozone in the troposphere are toxic and act as a greenhouse gas. Anthropogenic emissions of ozone precursors have caused widespread increases in ozone concentrations since the late 1800s, with the fastest-growing ozone precursor emissions currently coming out of east Asia.
Springtime ozone levels in the lower atmosphere over western North America are rising. The source of this pollution may be Asia, a finding that reaffirms the need for international air-quality control.
Vinson Kurian Japanese researchers have indicated the possibility of La Nina, the alter ego of monsoon-buster El Nino, to unfold over the equatorial Pacific later this year. La Nina, which represents shift of warmer sea-surface temperatures to the west equatorial Pacific, has generally coincided with a normal Indian monsoon, though there is no direct cause-effect relationship.
The Meteorological Department today installed a super-computing device, which will upgrade its short-range weather prediction to seven days.
For more than three hours today, scores of people watched in awe the annular solar eclipse
On the occasion of the 135th Foundation Day of the indian meteorological department (IMD), minister for science and technology and earth sciences Prithviraj Chavan inaugurated India's first mega computer (IBM P6) which will go long away in providing accurate weather predictions.
For Indian Space Research Organisation (ISRO) the rare and longest solar eclipse on Friday is going to be crucial to study the atmospheric changes and its consequences before, during and after the eclipse.
The elevation of the Tibetan plateau is thought to cause its surface to serve as a heat source that drives the South Asian summer monsoon, potentially coupling uplift of the plateau to climate changes on geologic timescales.
Received wisdom about the main driver of the South Asian monsoon comes into question with a report that tests the idea that the Himalayas, not the Tibetan plateau, are the essential topographic ingredient.
Ranchi, Jan. 10: Scientists of Birla Institute of Technology (BIT), Mesra, are getting ready to witness the solar eclipse that will occur on January 15, a day after Makar Sankranti.
