NASA Provides Satellite Views of Nor'easter

08.03.2013
The merging of two low pressure areas into a large Nor'easter on March 6 brought winter weather advisories and warnings to the Mid-Atlantic. NASA's Aqua satellite captured an infrared and near infrared image of the storm's power, and NASA created an animation of the storm's movement using NOAA's GOES-13 satellite imagery.

Infrared data from the Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite was made into a false-colored image of the Nor'easter from March 6 at 1817 UTC (1:17 p.m. EST). Infrared imagery shows temperature data. The coldest cloud tops indicate the highest storm clouds, and the strongest convection.

The coldest cloud top temperatures were near -45 Fahrenheit ( -43 Celsius), and were areas with the heaviest precipitation. At the time of the image, the coastal low pressure area's heaviest precipitation stretched over New Jersey, southeastern Pennsylvania, most of Maryland, Delaware, and eastern and northeast and central Virginia. Other areas of very cold cloud tops and heavy precipitation appeared over the Atlantic in the storm's arm, east and south of the center of circulation.

An animation of NOAA GOES-13 satellite imagery over the days of March 5, 6 and early on March 7 was created by the NASA GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md. The 24 second animation showed the progression of a cold front from the west associated with a low pressure system that brought snow from Chicago to the Appalachian Mountains. The low merged with a coastal low near the Mid-Atlantic on March 6 and brought up to 2 feet of snow in the Blue Ridge Mountains, while coastal areas and cities including Washington, D.C. and Baltimore received snow followed by heavy rain. The animation ends at 1331 UTC (8:31 a.m. EST) on March 7, when the nor'easter was affecting New England.

According to NOAA's National Operational Hydrologic Remote Sensing Center (NOHRSC) in Chanhassen, Minnesota, who compile and provide interactive snowfall information, the snowfall totals ranged from 18 inches in western northern Virginia to two-tenths of an inch at Reagan National Airport, Washington, D.C.

After the cold front and associated low that swept in from the Upper Mid-west merged with the coastal low pressure area, the coastal low pressure area became the driver. It brought in warmer temperatures from the Atlantic Ocean where sea surface temperatures were in the 40s (Fahrenheit). The warmer air helped keep the precipitation as rainfall in a line from Baltimore and Washington, D.C. eastward. It was the higher elevations in the Mid-Atlantic that saw the most snow.

According to NOHRSC, the Blue Ridge Mountains received the most snow, totaling up to 2 feet. Dulles Airport, Virginia received 3 inches; Blue Mountain, Virginia received 17 inches and Front Royal, Virginia received 12 inches. In Maryland, the city of Westminster which lies west of Baltimore received 4.5 inches, while Columbia, located south of Baltimore, received 2 inches of snow.

The strong winds that accompanied the nor'easter did cause wind warnings and advisories. According to the Baltimore Sun newspaper the winds toppled a tractor trailer truck on Maryland's Bay Bridge that connects to Annapolis. The bridge was closed for four hours. The winds caused tree damage and power outages in Maryland and Delaware. In western northern Virginia and western Maryland winds coupled with heavy, wet snow took down trees and left thousands without power.

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...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
