Fewer rain storms across southern Australia
In an address today to the International Union of Geodesy and Geophysics conference in Melbourne, CSIRO climate scientist, Dr Jorgen Frederiksen, said these changes are due to reductions in the strength of the mid-latitude jet stream and changes in atmospheric temperatures. The jet stream comprises fast moving westerly winds in the upper atmosphere. "The drop in winter and autumn rainfall ...

Regional climate models discussed at Lund conference
More than 200 researchers from around the world are meeting this week in Lund to evaluate the recent development of regional climate models. These models have certainly been improved greatly in recent years; they can be refined further to provide even better support for the preparations we must make for future climate change. That climate change, very largely caused by human activities, is ...

Torrential rainfall a common climate feature in the future
Changes in the climate are expected to result in heavier rainfall. Calculations with climate models show that a heavy downpour will give 20-30 per cent more rain at the turn of the next century. Thunder showers and torrential rainfall in the summer are part of what, in technical jargon, is called extreme or intensive short-term precipitation. “Intensive short-term precipitation is the ...

Weather and climate get a supercomputing boost in Australia
Two new supercomputers ordered today by the Bureau of Meteorology and The Australian National University (ANU) will deliver 12 times the power of previous models, ensuring Australia is at the forefront of international weather forecasting and climate modelling. The Bureau and ANU have selected Sun Microsystems to deliver two state-of-the-art supercomputers capable of processing the vast amount of ...

Space mission set to monitor the effects of climate change
NPL is helping the UK play a key role in an international space mission to predict the effects of climate change. EarthCARE is a mission to compare cloud distribution with radiation, giving a more detailed picture of how clouds affect climate change. It is run jointly by the European Space Agency (ESA) and the Japanese Aerospace Exploration Agency (JAXA). Scientists know that clouds can affect ...

A hard rain`s gonna fall
Analysis shows climate change to yield more extreme rainfall. Heavier rainstorms lie in our future. That's the clear conclusion of a new MIT and Caltech study on the impact that global climate change will have on precipitation patterns. But the increase in extreme downpours is not uniformly spread around the world, the analysis shows. While the pattern is clear and consistent outside of the ...

Experts to study aerosols’ impact on Australia’s climate
The impact that human-generated and natural atmospheric particles (aerosols) could be having on Australia’s climate will be discussed next week in Canberra at a workshop involving some of the world’s leading experts in the area. CSIRO Marine and Atmospheric Research scientist, Dr Leon Rotstayn, says the influence aerosols have on climate is still one of the ‘great unknowns’ in climate science. ...

Climate data project seeks to prepare poorer nations
A global initiative to help developing nations prepare for the impacts of climate change will be piloted in Bangladesh, Colombia and Ethiopia, following its launch in the United States last week. The Climate Services for Resilient Development partnership has more than US$34 million worth of funding and goods to use to pool scientific data and technologies from agencies in the United States and ...

NASA Study Projects Warming-Driven Changes In Global Rainfall
A NASA-led modeling study provides new evidence that global warming may increase the risk for extreme rainfall and drought. The study shows for the first time how rising carbon dioxide concentrations could affect the entire range of rainfall types on Earth. Analysis of computer simulations from 14 climate models indicates wet regions of the world, such as the equatorial Pacific Ocean and Asian ...

Biral Sensors used in Antarctic Climate-Change Research
Sensors from meteorological specialists, Biral, are currently being used in Antarctic Climate-Change Research mission, headed by a French research group. The APRES3 campaign is a long term project with the aim of measuring precipitation in Antarctica, as well as monitoring climate change to understand the effect APRES3, Antarcticathis has on the ice sheets. Biral’s VPF-730 Visibility and ...

Climate change brings ill winds for airline industry
Global warming may already be taking its toll of air miles. As jet planes burn fuel and release carbon dioxide, the atmosphere warms and causes head winds to build up. Tail winds do too, but round trip journey times are nevertheless creeping up − and so are fuel costs. A team of US scientists say the cumulative effect of the longer flight times that they think may have resulted from ...

ESRL scientists study California’s water future in a changing climate
Water security is never far from the mind of any decision maker in the U.S. West— but it’s not a terrorist attack on a dam or canal that triggers the most anxiety, it’s climate change. This fall, California Gov. Arnold Schwarzenegger called his state’s water troubles a “holy water war” pitting “north versus south, California versus the feds, rural versus urban....” And well known challenges— the ...

EUMETSAT launches into operational satellite altimetry
Preparations are on track and everything is on schedule for the launch of Jason-2 15 June 2008. Through the Jason-2/OSTM programme, EUMETSAT will be able to address one of its top priorities - assuming a growing European role in the processing and dissemination of ocean altimetry data from satellite sources, to expand its traditional focus on supporting atmospheric weather and climate ...

NPL hosts Metrology for Climate meeting
The two-day event, entitled 'Metrology for Climate', provided structured workshop sessions to investigate and prioritise the role that metrology should play in supporting the robust measurement of Essential Climate Variables (ECVs). There are 50 ECVs associated with the three Atmospheric, Oceanic and Terrestrial domains, and the concept provides a crucial systematic and internationally consistent ...

2017 among the three warmest years recorded
For all of us, as 2017 proves one of the three warmest years on record, climate change presents a greater risk of sickness or death than it did four decades ago, the United Nations says. And for some of the world’s poorest people, the consequences of unpredictable weather caused by changing climate mean devastating disruption to their daily lives. The news comes from the World ...
