A better understanding of key partners and users – and the type of information they need to prepare for and react to weather events – will increase the likelihood of success of the hydrometeorological enterprise as it works collectively to achieve its mission of saving lives and property.

Just over a month after launch, Jason-3, a U.S.-European oceanography satellite mission with NASA participation, has produced its first complete science map of global sea surface height, capturing the current signal of the 2015-16 El Niño. The map was generated from the first 10 days of data collected once Jason-3 reached its operational orbit of 1,336 kilometers on Feb. 12. It shows the continuing evolution of the ongoing El Niño event that began early last year.

Governments, private companies and individuals are demanding ever more sophisticated climate services, as manifested by the Global Framework for Climate Services (GFCS). But parts of the ocean observation network – paramount to the delivery of climate services – are at risk, and the evolution of climate prediction systems is not keeping pace in terms of accuracy and reliability. We are at a critical stage in observing and predicting the El Niño-Southern Oscillation (ENSO).

Global temperature records were broken yet again in April for the 12th consecutive month, the longest such streak in the 137-year record of the U.S. National Oceanic and Atmospheric Administration (NOAA ). Overall, 13 out of the 15 highest monthly temperature departures in the record have all occurred since February 2015. NOAA said the combined average temperature over global land and ocean surfaces for April 2016 was 1.10°C (1.98°F) above the 20th century average of 13.7°C (56.7°F) - the highest temperature departure for April since global records began in 1880. This value surpassed the...

Activities involving transportation are inherently more sensitive to weather events than activities that are located in a single place. Consider an individual contemplating a ten minute walk to his favourite coffee shop: indoors, he is not particularly weather-sensitive but once outdoors, the situation changes substantially.

The theme of World Meteorological Day this year is “Weather, climate and the air we breathe”. This issue of the Bulletin is conceived around the same theme, with articles on air quality and its manifestation in urban and surrounding regions, couplings with weather and climate change and the impact of pollutant deposition, including nitrogen, on the upper ocean. It opens with a message from the Secretary-General on the occasion of World Meteorological Day, as is customary in the January Bulletin.

Water managers and engineers sometimes make use of climate information and predictions at a range of temporal and spatial scales, and at other times use their own techniques to account for climate variability. In the longer term, the impacts of global warming will become of greater interest to water managers, as will improved short- and medium-term climate and hydrological predictions.

“Health Oceans, Healthy Planet” is the theme of World Oceans Day on 8 June, reflecting the vital role of oceans in sustaining life on earth. “We don’t need to be reminded of the challenges we currently face with a changing climate: the impacts on the ocean are clear: sea level rise, eroding coastlines, warmer waters and ocean acidification,” said World Meteorological Organization Secretary-General Petteri Taalas. “We are currently witnessing unprecedented coral bleaching, which may be endangering some of the world’s best-known coral reefs. The powerful El Niño event and long-term global...
