Seasonal Tropical Cyclone Forecasts
Bulletin nº Vol 56 (4) - 2007
1
Publish Date: 1 October 2007
Seasonal forecasts of tropical cyclone activity in various regions have been developed since the first attempts in the early 1980s by Neville Nicholls (1979) for the Australian region and William Gray (1984(a), (b)) for the North Atlantic region. Over time, forecasts for different regions, using differing methodologies, have been developed.
Observing the Polar Oceans during the International Polar Year and beyond
Bulletin nº Vol 56 (4) - 2007

Publish Date: 1 October 2007
Leaving behind a legacy is a key aim of the International Polar Year (IPY) 2007-2008. One of the key legacies from the International Geophysical Year (IGY) of 1957-1958 was the establishment of a network of bases in the Antarctic that would provide springboards for a greatly enhanced programme of exploration of the interior of the continent.
Match Campaigns to Measure Stratospheric Ozone Loss—a Key Contribution to International Polar Year 2007-2008
Bulletin nº Vol 56 (4) - 2007

Publish Date: 1 October 2007
The year 2007 marks an important event in geosciences—the 125th anniversary of the first International Polar Year (IPY) 1882-1883. The activities started during the first IPY and its follow-ups in 1932-1933, in particular the International Geophysical Year 1957-1958, laid the ground for many important elements of our current understanding of the Earth system.

He was, for 36 years (1958-1994), the revered leader of meteorology in the Philippines and for eight remarkable years (1979-1987) the much-loved President of WMO; a brilliant member of a brilliant family, a veteran of eight World Meteorological Congresses and a man so modest that, in early 1979, he was among the last to realize that the entire WMO community had already decided that he should become the fifth President of WMO.

State and fate of the polar cryosphere, including variability of the Arctic hydrological cycle
Bulletin nº Vol 56 (4) - 2007
1
Publish Date: 1 October 2007
The cryosphere collectively describes elements of the Earth system which contain water in its frozen state and include sea, lake and river ice, snow cover, solid precipitation, glaciers, ice caps, ice sheets, permafrost and seasonally frozen ground.
The Chemical Composition of the Polar Atmosphere—the IPY Contribution
Bulletin nº Vol 56 (4) - 2007

Publish Date: 1 October 2007
The polar atmosphere is remote from pollution sources of chemical trace species. Its composition has traditionally been seen as a clean background for more polluted air over the continents and their adjacent marine areas. This view of the polar regions as both clean and simple has gradually changed over the last decades, starting with polar route aircraft pilots observing haze and reduced visibility. Meanwhile, polar stratospheric ozone depletion, particularly strong in the Antarctic, was discovered more than two decades ago.

Publish Date: 1 October 2007
So far, there have been two so-called Polar Years separated in time by 50 years: the First International Polar Year took place in 1882-1883 and established a precedent for international science cooperation.
