NASA satellite sees a warm winter in the Western US

24.02.2015

While people in the eastern two-thirds of the U.S have been dealing with Arctic Air, the bulge in the Jet Stream over the eastern Pacific Ocean has been keeping the western third of the U.S. in warmer than normal temperatures over the last two months. Infrared data from NASA provided a look at those surface temperature extremes from west to east.

Californians have been flaunting their flip-flops and tee shirt weather at friends and relatives on the frigid East Coast. The contrast is extreme, Californians are experiencing their warmest winter since modern record keeping began and Bostonians are staggering through 8 foot and higher snowdrifts. Why?

"It's the weather-controlling polar jet stream - a fast river of wind in the upper atmosphere - that has been locked in an extreme pattern for the past few years," explained Climatologist Bill Patzert of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California.

"Rather than circling in a relatively straight path, the jet stream has meandered in great north-south waves. In the west, it's been bulging northward, arguably for the past two winters - a pattern meteorologists have nick named the 'Ridiculously Resilient Ridge.' Over frigid northern Canada, the jet takes a hard right turn and plunges into the upper Midwest and East Coast, plummeting temperatures and creating punishing ice and snow storms."

Those temperatures are apparent on infrared data taken on Feb. 18 at 18:53 UTC (1:53 p.m. EST) from the Atmospheric Infrared Sounder or AIRS instrument that flies aboard NASA's Aqua satellite. AIRS data are processed and made into false-colored imagery at NASA's JPL.

In the image from Feb. 18, surface temperatures from Washington State, south to California, Nevada, Arizona, New Mexico and western Texas appeared quite warm. Surface temperatures ranged from 290K/62.3F/16.8C to 300K/80.3F/26.8 C.

On Feb. 18, when the AIRS data was taken, the high temperature in Los Angeles, California reached 75F. That was one of 10 days out of the first 20 days of February, where temperatures reached or passed that mark in the city.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
