A Bomb Cyclone Is One of Two Major Storms Walloping the U.S. Thanksgiving Week
Two major storms are already walloping the U.S. in time for Thanksgiving.
A winter storm that has already killed one moved from Colorado, Wyoming and Nebraska into the Midwest Wednesday, while a "bomb cyclone" hit the Oregon coast Tuesday evening, according to an Associated Press story published by The Washington Post.
"This is an unprecedented storm given the track and strength and will bring very dangerous conditions to the area," the National Weather Service (NWS) in Medford, Oregon, said of the second storm, according to USA Today. "High winds and heavy snow is expected to impact the area."

The first storm unleashed nearly three feet of snow on Colorado and led to one death and two injuries when a tractor-trailer collided with two trucks near Vail, Colorado, the Associated Press reported. It also forced the Denver airport to cancel around 30 percent of its flights.
The storm is expected to heap a foot of snow on a region stretching from the Plains, to the upper Mississippi Valley, to the upper Great Lakes and northern Maine, and could disrupt airports along the way, NPR reported.
It is also predicted to unleash wind gusts of more than 50 miles per hour in the Midwest and Ohio Valley region, according to NWS.

Wind from the storm system could even disrupt the Macy's Thanksgiving Day Parade: its iconic balloons will have to be grounded if forecast 40-50 mile per hour wind gusts materialize, the Associated Press reported.
The second storm already set a record for the lowest pressure for the month of November Tuesday evening, when its central pressure bottomed out at 970 millibars, according to NWS.
"In general, the lower the pressure, the stronger the storm," The Washington Post's Capital Weather Gang explained.
The storm strengthened through a process called bombogenesis, when a cyclone's pressure drops at least 24 millibars in 24 hours. Storms that accomplish this feat are referred to as "bomb cyclones." Medford NWS staffer Tom Wright said the air pressure of Tuesday's storm dropped even more quickly than that, according to an Associated Press story published by The Columbian.
The storm is now weakening, but it has already generated sustained winds of up to 85 miles per hour in parts of Oregon and up to 34 foot seas, according to the NWS. It has unleashed heavy rains on the coasts of Southwest Oregon and Northern and Central California and heavy snow in the mountains.
The OR/CA storm peaked pressure-wise with a central pressure of 970 hPa/28.64" at 7 pm PST before slowly weakening.… https://t.co/tFkYq80SXP— NWS WPC (@NWS WPC)1574835035.0
It has also led to the closure of roads in Southern Oregon because of downed trees and power lines and blizzard-like driving conditions, according to the Associated Press story published by The Washington Post.
"It's blowing pretty good outside but because we're right on the coast, everything was built to ensure the safety of people," Northern California hotel manager Angela Smith told the Associated Press.
She said her Oceanfront Lodge briefly lost power.

After a Japanese-owned oil tanker struck a reef off Mauritius on July 25, a prolonged period of inaction is threatening to become an ecological disaster.

How to Tackle Oil Spills<p>The method for tackling oil spills depends on several factors, including the type and amount of oil in question, location and weather conditions.</p><p>"Once the oil comes to shore, the more intensive the cleaning technique. You can risk causing further damage," said Nicky Cariglia, an independent consultant at Marittima, who specializes in marine pollution. </p><p>"If you wanted to remove all traces of oil, the techniques available become increasingly aggressive the less oil that remains. In mangroves, you would have the added risk of causing damage by trampling," Cariglia told DW. Highly sensitive mangrove ecosystems line the Mauritius east coast that is threatened by the current spill.</p><p>Because oil normally has a lower density than water, it floats on the surface of the ocean. This means that for clean-up action to be most effective, it should happen very quickly after a spill, before the oil disperses. </p>

The temperature of the Arctic matters to the entire world: it helps to keep the global climate fairly cool. Scientists now say that by 2035 there could be an end to Arctic sea ice.
Melt Ponds Crucial<p>"The prospect of loss of sea ice by 2035 should really be focusing all our minds on achieving a low-carbon world as soon as humanly feasible."</p><p><a href="http://www.reading.ac.uk/search/search-staff-details.aspx?id=10813" target="_blank">Dr. David Schroeder from the University of Reading</a>, UK, who co-led the implementation of the melt pond scheme in the climate model, says, "This shows just how important sea ice processes like melt ponds are in the Arctic, and why it is crucial that they are incorporated into climate models."</p><p>The extent of the areas <a href="https://nsidc.org/cryosphere/seaice/characteristics/formation.html" target="_blank">sea ice</a> covers varies between summer and winter. If more solar energy is absorbed at the surface, and temperatures rise further, a cycle of warming and melting occurs during summer months.</p><p>When the ice forms, the ocean water beneath becomes saltier and denser than the surrounding ocean. Saltier water sinks and moves along the ocean bottom towards the equator, while warm water from mid-depths to the surface travels from the equator towards the poles.</p><p>Scientists refer to this process as the ocean's global "conveyor-belt." Changes to the volume of sea ice can disrupt normal ocean circulation, with consequences for global climate. </p>
