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

Pune A B Mazumdar, deputy director general (weather forecasting) and Medha Khole, director (weather forecasting) of the India Meteorology Department (IMD), Pune, in a free-wheeling chat with the staff of The Indian Express and Loksatta, answered a range of questions relating to weather forecasting and unveiled the science behind it. What is the progress on the dedicated weather news channel
<p>A Southern Ocean Pilot cruise covering the latitudes from 10°N to 56°S in the open Indian Ocean was car-<br /> ried out during January–February 2004. Surface and upper air data collected during this cruise are re-<br /> ported here. It is shown that the broad features of the atmosphere, in particular that of temperature, follow
<p>Extensive measurements of columnar aerosol optical depth (AOD), composite (MT) and black carbon aero-<br /> sol mass (MB) concentrations were made over the tropical Indian and Southern Oceans as a part of the<br /> Pilot Expedition to the Southern Ocean during the boreal winter. The AOD, MT and MB show large lati-
Stable isotope (? 18O and ? D) and salinity measurements were made on the surface waters collected from the Southern Indian Ocean during the austral summer (25 January to 1 April 2006) onboard R/V Akademik Boris Petrov to study the relative dominance of various hydrological processes, viz. evaporation, precipitation, melting and freezing over different latitudes.
This study discusses the upwelling observed in Prydz Bay, coastal waters of East Antarctica. In February 2006, as a part of expedition to Larsemann Hills (East Antarctica) three hourly conductivity, temperature, depth (CTD) observations were carried out for three consecutive days in Prydz Bay coastal waters.
Iron fertilization of the Southern Ocean is believed to counter the increasing CO2 concentration in the atmosphere and the consequent global warming. Though a number of large scale iron enrichment experiments have been done in the recent past in different parts of the world ocean, little effort has been made to understand the effect of iron enrichment on nitrogen uptake rates and f-ratios.

Ground level ozone concentrations ([O3]) typically show a direct linear relationship with surface air temperature. Three decades of California measurements provide evidence of a statistically significant change in the ozone-temperature slope (?mO3-T) under extremely high temperatures (> 312 K).
It is a well-known fact that the frequency of cyclones is 3
