Weather, Climate and the Air We Breathe
Bulletin nº Vol 58 (1) - 2009
1
Publish Date: 1 January 2009
This theme is particularly appropriate at a time when communities around the globe are struggling to attain the United Nations Millennium Development Goals, especially in terms of health, food, water security and poverty alleviation, as well as to increase their effectiveness in preventing and mitigating natural disasters, of which 90 per cent are directly related to weather, climate and water hazards ...
The Impacts of Atmospheric Deposition to the Ocean on Marine Ecosystems and Climate
Bulletin nº Vol 58 (1) - 2009
1
Publish Date: 1 January 2009
https://www.uea.ac.uk/environmental-sciences The transfer of chemicals from the atmosphere to the ocean has long had an impact on the ocean (e.g. nutrient source; pH influence). With the advent of the Anthropocene, the transfer of some chemicals has increased over natural levels and the transfer of new chemicals has commenced. This brief review examines the impact of the increased transfer of certain nutrients (nitrogen, iron and phosphorus), toxins (lead and mercury) and pH regulators (carbon dioxide) on ocean ecosystems and climate.
Implications of Climate Change for Air Quality
Bulletin nº Vol 58 (1) - 2009
1
Publish Date: 1 January 2009
Changes in the chemical composition of the atmosphere, which have resulted from massive industrialization, intensive agriculture and urbanization, as well as road, maritime and air traffic, have led directly and indirectly to enhanced radiative forcing with, as a result, future changes in the Earth’s temperatures and hydrological cycles.
60 Years of Service for Your Safety and Well-Being
Bulletin nº Vol 59 (1) - 2010

Publish Date: 1 January 2010
Every year on 23 March, the World Meteorological Organization (WMO) and the international meteorological community join in celebrating World Meteorological Day, to commemorate the coming into force of the WMO Convention on 23 March 1950, precisely 30 days after the day when the thirtieth instrument of ratification of the Convention was deposited by countries wishing to join the new Organization.
The Global Satellite Observing System: a Success Story
Bulletin nº Vol 59 (1) - 2010
1
Publish Date: 1 January 2010
The first launches of artificial satellites beginning with Sputnik on 4 October 1957 by the Soviet Union and with Explorer I by the United States of America on 2 January 1958 heralded a new era of Earth observation.
Pioneering the Collection and Exchange of Meteorological Data
Bulletin nº Vol 59 (1) - 2010
1
Publish Date: 1 January 2010
Over the past 60 years, WMO and its Members have created and evolved observing and information systems to meet the ever-growing challenges of an increasingly complex society.
Public Weather Services for Disaster Risk Reduction
Bulletin nº Vol 59 (1) - 2010
1
Publish Date: 1 January 2010
National Meteorological and Hydrological Services all over the world have an essential role to play in bringing about disaster reduction through delivery of quality public weather services, including the provision of weather forecasts, early warnings on hazardous weather, outreach activities to enhance public awareness of weather hazards, interpretation and use of the weather information, as well as collaboration with disaster relief organizations to minimize loss of life and property.
WCC-3 High-Level Segment: in Their Own Words
Bulletin nº Vol 59 (1) - 2010
1
Publish Date: 1 January 2010
During the High-level Segment of WCC-3, from 3 to 4 September 2009, high-level policy-makers from 160 countries agreed to establish a Global Framework for Climate Services to “strengthen production, availability, delivery and application of science-based climate prediction and services”.
The Carbonaceous Aerosol—a Remaining Challenge
Bulletin nº Vol 58 (1) - 2009
1
Publish Date: 1 January 2009
The ambient aerosol level remains a major challenge in atmospheric science due to its ability to cause negative health effects and its ability to influence the radiative balance and, thus, the Earth’s surface temperature. Our knowledge of the mechanisms by which the effects can be explained, however, is still a matter of ongoing research.
Working to Standardize Instruments and Methods of Observation
Bulletin nº Vol 59 (1) - 2010
1
Publish Date: 1 January 2010
Requirements for high-quality observational data and their worldwide compatibility were a governing principle when the International Meteorological Organization was established in 1873.
