NASA Satellites Capture a Stronger La Nina

New NASA satellite data indicate the current La Niña event in the eastern Pacific has remained strong during November and December 2010.

A new Ocean Surface Topography Mission (OSTM)/Jason-2 satellite image of the Pacific Ocean that averaged 10 days of data was just released from NASA. The image, centered on Dec. 26, 2010, was created at NASA's Jet Propulsion Laboratory (JPL), Pasadena, Calif.

The La Niña is evident by the large pool cooler than normal (blue and purple) water stretching from the eastern to the central Pacific Ocean, reflecting lower than normal sea surface heights. \\\"This La Niña has strengthened for the past seven months, and is one of the most intense events of the past half century,\\\" said Climatologist Bill Patzert of NASA JPL.

"The solid record of La Niña strength only goes back about 50 years and this latest event appears to be one of the strongest ones over this time period," said Climatologist Bill Patzert of JPL. "It is already impacting weather and climate all around the planet."

"Although exacerbated by precipitation from a tropical cyclone, rainfalls of historic proportion in eastern Queensland, Australia have led to levels of flooding usually only seen once in a century," said David Adamec, Oceanographer at NASA's Goddard Space Flight Center, Greenbelt, Md. "The copious rainfall is a direct result of La Niña’s effect on the Pacific trade winds and has made tropical Australia particularly rainy this year."

The new image depicts places where the Pacific sea surface height is near-normal, higher (warmer) than normal and lower (cooler) than normal. The cooler-than normal pool of water that stretches from the eastern to the central Pacific Ocean is a hallmark of a La Niña event.

Earth's ocean is the greatest influence on global climate. Only from space can we observe our vast ocean on a global scale and monitor critical changes in ocean currents and heat storage. Continuous data from satellites like OSTM/Jason-2 help us understand and foresee the effects of ocean changes on our climate and on climate events such as La Niña and El Niño.

The latest report from NOAA's Climate Prediction Center (CPC) noted that "A moderate-to-strong La Niña continued during December 2010 as reflected by well below-average sea surface temperatures (SSTs) across the equatorial Pacific Ocean." The CPC report said that La Niña is expected to continue well into the Northern Hemisphere spring 2011.

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
