The report discusses the climate condition over Indian region during the year 2023. Notably, global temperatures soared to exceptionally high levels during this period (WMO.No.1347). The India Meteorological Department continuously monitors weather and climate over Indian region. The annual mean land surface air temperature averaged over India during 2023 was …
Over the course of six years (2006–2011), equivalent black carbon (eqBC), coarse aerosol mass (PM 1–10), and surface ozone (O 3), observed during the monsoon onset period at the Nepal Climate Observatory–Pyramid WMO/GAW Global Station (NCO-P, 5079 m a.s.l.), were analyzed to investigate events characterized by a significant increase in …
The objective of this study is to evaluate the ability of a European chemistry transport model, ‘CHIMERE’ driven by the US meteorological model MM5, in simulating aerosol concentrations [dust, PM10 and black carbon (BC)] over the Indian region. An evaluation of a meteorological event (dust storm); impact of change in …
This is an advisory note on the integration of disaster risk reduction and climate change adaptation into sustainable development, as part of the science and policy knowledge series. The advisory note 'El Niño 2014/2015: Policy implications for Asia and the Pacific' provides a 14 page overview of El Niño, its …
The urban heat island (UHI), a common phenomenon in which surface temperatures are higher in urban areas than in surrounding rural areas, represents one of the most significant human-induced changes to Earth’s surface climate. Even though they are localized hotspots in the landscape, UHIs have a profound impact on the …
Dissolved iron is an essential micronutrient for marine phytoplankton, and its availability controls patterns of primary productivity and carbon cycling throughout the oceans. The relative importance of different sources of iron to the oceans is not well known, however, and flux estimates from atmospheric dust, hydrothermal vents and oceanic sediments …
The study focuses on understanding the variations of precipitation during summer monsoon season and its impact on Kharif and Rabi foodgrain yield over India. Total foodgrain yield over India during Kharif (summer) season is directly affected by variations in the summer monsoon precipitation (June–September). An increase (decrease) in rainfall is …
The temporal and spatial variability of the various meteorological parameters over India and its different subregions is high. The Indian subcontinent is surrounded by the complex Himalayan topography in north and the vast oceans in the east, west and south. Such distributions have dominant influence over its climate and thus …
This report documents and analyses emerging trends in the delivery and exchange of climate information in institutionalized agricultural extension systems, as well as through information and communication technologies for development (ICT4D) efforts that have a rural–agricultural focus. Such an analysis aims to give a clearer indication of how to best …

The temporal and spatial dynamics of primary and secondary biomass/production in the Barents Sea since the late 1990s are examined using remote sensing data, observations and a coupled physical-biological model. Field observations of mesozooplankton biomass, and chlorophyll a data from transects (different seasons) and large-scale surveys (autumn) were used for …
Currently the ENSO conditions over equatorial Pacific are in the border line between warm ENSO neutral and weak El Nino conditions. Latest forecasts from almost all ENSO prediction models indicate a transition to sustained El Nino conditions during the southwest monsoon with probability of about 70%. The chance for El …
The fifth session of the SASCOF (SASCOF-5), convened to generate the climate outlook for the summer monsoon season of 2014, was held at Pune, India, from 22-23 April 2014 with the participation of eight South Asian countries. It was preceded by a capacity building training workshop on seasonal prediction for …
Sunday night’s showers and the prevailing overcast sky has left Surinder Doda of Nigdhu village worried, much like other farmers of the state. His wheat crop is ready for harvesting, but the bad weather conditions have become a threat for the crop. Dr Indu Sharma, director, Directorate of Wheat Research …
A 2013 scientific assessment of black carbon emissions and impacts found that black carbon is second to carbon dioxide in terms of its climate forcing. High concentrations of black carbon in the atmosphere can change precipitation patterns and reduce the amount of radiation that reaches the Earth's surface, which affects …
This State of the Climate is the third in a series of reports produced by CSIRO and the Australian Bureau of Meteorology. It provides a summary of observations of Australia’s climate and analysis of the factors that influence it.
The emergence of the El Nino weather phenomenon is likely to coincide with the monsoon season (June-September) this year, India Metrological Department’s (IMD) Regional Climate Centre in Pune said in its Seasonal Climate Outlook for South Asia (April-July) report. The weather bureau is likely to release its forecast for June-September …
A comparison among firewood, charcoal and LPG shows that each energy source has its own specific advantages, inconveniences and limitations. They should be considered jointly within a comprehensive, inter-sectoral energy strategy that provides an effective framework for governments. Fossil fuels are required in areas where the ecological limits of woodfuel …
The current El Niño/Southern Oscillation (ENSO) neutral conditions are most likely to continue in to the second quarter of 2014. However, there is an enhanced possibility of development of a weak El Niño during the middle of 2014. However, the probability for neutral ENSO is also as high as for …
