Satellite Video Shows Movement of Major U.S. Winter Storm

February 12, 2014

 

This animation of NOAA’s GOES satellite data shows the progression of the major winter storm in the U.S. south from Feb. 10 at 1815 UTC/1:15 p.m. EST to Feb. 12 to 1845 UTC/1:45 p.m. EST.

A new NASA video of NOAA’s GOES satellite imagery shows three days of movement of the massive winter storm that stretches from the southern U.S. to the northeast.

Visible and infrared imagery from NOAA’s GOES-East or GOES-13 satellite from Feb. 10 at 1815 UTC/1:15 p.m. EST to Feb. 12 to 1845 UTC/1:45 p.m. EST were compiled into a video made by NASA/NOAA’s GOES Project at NASA’s Goddard Space Flight Center in Greenbelt, Md.

In the video, viewers can see the development and movement of the clouds associated with the progression of the frontal system and related low pressure areas that make up the massive storm. The video also shows the snow covered ground over the Great Lakes region and Ohio Valley that stretches to northern New England. The clouds and fallen snow data from NOAA’s GOES-East satellite were overlaid on a true-color image of land and ocean created by data from the Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA’s Aqua and Terra satellites.

On February 12 at 10 a.m. EST, NOAA’s National Weather Service or NWS continued to issue watches and warnings from Texas to New England. Specifically, NWS cited Winter Storm Warnings and Winter Weather Advisories were in effect from eastern Texas eastward across the interior section of southeastern U.S. states and across much of the eastern seaboard including the Appalachians. Winter storm watches are in effect for portions of northern New England as well as along the western slopes of northern and central Appalachians.

NOAA’s Weather Prediction Center or WPC noted the storm is expected to bring “freezing rain spreading into the Carolinas, significant snow accumulations are expected in the interior Mid-Atlantic states tonight into Thursday and ice storm warnings and freezing rain advisories are in effect across much of central Georgia.

GOES satellites provide the kind of continuous monitoring necessary for intensive data analysis. Geostationary describes an orbit in which a satellite is always in the same position with respect to the rotating Earth. This allows GOES to hover continuously over one position on Earth’s surface, appearing stationary. As a result, GOES provide a constant vigil for the atmospheric “triggers” for severe weather conditions such as tornadoes, flash floods, hail storms and hurricanes.

HONOLULU (AP) — Lava flowing from a Hawaii volcano is inspiring innovative ideas from local students on how to deal with its effects.

Students from Pahoa’s Hawaii Academy of Arts and Science came up with an idea for an air scrubber for volcanic smog, or vog. The scrubber pulls vog from the air with a fan and neutralizes acidity with a compound similar to baking soda.

As of Monday, Pahoa’s ACE Hardware was selling parts for the scrubber for $100, the Honolulu Star-Advertiser reported (http://ow.ly/EpEc4 ).

A scrubber assembled by the students goes for $150. The extra $50 will go to the Big Island school’s science, technology, engineering and math program to help fund future research.

The students are in a small town threatened by the slow-moving lava, which entered Pahoa last month and burned down a house.

“It feels good to be able to help our community,” student Logan Treaster said. The 17-year-old senior was personally affected by the vog when a classmate had to move away because of sensitivity to it.

The flow hasn’t advanced since Saturday, Hawaii County Civil Defense said.

Health officials previously advised people living near the lava to prepare for smoke from burning vegetation, along with low levels of sulfur dioxide. Residents with respiratory problems should take precautions and stay indoors, the civil defense agency said.

“It smells like rotten eggs,” Treaster said of the odor that permeates the area almost daily.

The students have come up with other lava-related ideas, including one similar to new technology a power company is using to protect poles in the flow’s path. They also have shared thoughts on a water-cooled bridge that would let drivers cross lava-covered roads.

“We teach giving back,” teacher Eric Clause said. “I also teach the kids: You can work the problem — or you can let the problem work you.”

Unit 7: Solutions – Study Guide

This is what you need to know for the quiz on Monday.

Vocabulary:

Solution: a combination of a solute and a solvent where the molecules of the solute are distributed in the liquid solvent and not clumped together into solid particles. Examples of solutions are salt in water (saline solution), sugar in water or oil in acetone.

Solute: the material being dissolved such as salt or sugar. Solutes can be solid, liquid or gas before being dissolved.  Examples include: sugar (solid) dissolved in water,  isopropal alcohol (liquid) dissolved in water (rubbing alcohol), CO2 gas dissolved in water (caronated water) or in juice (soft drinks).

Solvent: the material, typically a liquid which does the dissolving such as water or acetone or an oil. Water is a polar solvent, oils are non-polar solvents.

Polar molecules: molecules where there is a slight charge separation across the molecule. The most notorious polar molecule is water, where the Oxygen has a slightly negative (-) charge and the Hydrogens have a slightly positive (+) charge.  Other polar molecules, in particular polar covalent molecules such as alcohols, can be dissolved in water since water is a polar solvent. Polar solvents can dissolve some ionic compounds since each ion has + or a – charge and each can be dissolved in water which is a polar solvent. Note that in many ionic solids such as many semiprecious crystals, the ionic bonding forces are stronger than the effect of the charge separation in the water molecule. This means that many ionic compounds are too strongly bonded to be dissolved in water. One example is a granite rock which was demonstrated to not dissolve.

Non-polar: Many covalently bonded molecules do not have a charge separation across the molecule and cannot be dissolved in water. Frequently these materials can be dissolved in non-polar solvents such as oils or other organic solvents (oils, acetone, paint thinner).

Insoluabilty: this happens when you try to dessolve a non-polar solute in a polar solvent. for example try to dissolve cooking oil in water.  This lighter liquid, in this case the cooking oil will float on top.

OK, so here’s Hank to explain it all and even some more stuff…….
