What A Cold Front! 

Dan\'s Wild Wild Science Journal [2015-11-29 05:58:31]  recommend  recommend this post  (20 visits) info
A rather incredible surface temperature chart greeted meteorologists this afternoon. An extremely sharp frontal boundary separated very warm weather from unusually cold. Behind the front, temperatures were 10-20 degrees below average, and ahead of it 10-15 degrees above average, and in some spots the departure from normal was even greater. Look at the temperatures at 1 PM EST and you can see that towns in western MS were reporting temps.

Meteorite impact turns silica into stishovite in a billionth of a second

The Barringer meteor crater is an iconic Arizona landmark, more than 1km wide and 170 metres deep, left behind by a massive 300,000 tonne meteorite that hit Earth 50,000 years ago with a force equivalent to a ten megaton nuclear bomb. The forces unleashed by such an impact are hard to comprehend, but a team of Stanford scientists has recreated the conditions experienced during the first billionths of a second as the meteor struck in order to reveal the effects it had on the rock underneath.

Corals and Climate Change

Corals are already facing a host of stressors – from pollution and overfishing to tourism and coastal development – but climate change puts corals at greater risk from rising temperatures and ocean acidification. The decline of coral reefs will have devastating consequences for the ocean, and for

Mini ice age?

Mini Ice Age may be heading our way! Met Office issues warning that temperatures could plummet as Sun enters cooler phase. The last big chill was felt hundreds of years ago when Frost Fairs were held on the frozen River Thames. The prediction is based on counting sun spots – dark patches on the sun – that are hot spots and signs of increased solar activity.Read

Weather a Bit Less Strange? Death Valley in the Last Two Days: Hot!

There is, of course, hardly such a thing as "average" weather, just like there is no "average" precipitation. I'm pretty sure that the number of days in a given year that actually match the average temperature is  limited. I've been to Death Valley twice in the last two weeks; for Memorial Day weekend, when the temperatures were very cool, like twenty degrees below average, and rainy. I

One of the goals of this expedition is to investigate if water from the Southern Ocean with temperatures above the melting point of glaciers could reach the glaciers in East Antarctica, and if there are any obstacles on the seafloor of the shelf that impact the ability of such water to reach the glaciers and

Amazing Temperature Change Over The Mid-Atlantic Friday

Here are two maps showing the temperatures at 5 Am and 4 PM. Many areas saw a rise of over 34 degrees in just a few hours today. This rapid change in temperature was made possible by two things. Ocean and elevation. At sunrise a chilly easterly wind off the cold Atlantic (where water temps are only around 42 degrees) had pushed all the way to the Blue Ridge Mountains

What Less Fog and Clouds Mean for Coastal Southern California

A new report released by the city today gives a worrisome picture of climate-related problems the New York metropolitan region will likely face this century. Temperatures are projected to rise, extreme precipitation and heat waves will be more frequent, and sea level could reach 6 feet under the worst-case scenario. The New York metropolitan region has been preparing to meet these

Measuring the temperature of solar winds 

AGU Meetings [2015-01-05 16:16:13]  recommend  recommend this post  (60 visits) info

The sun spews forth super-heated, charged particles, collectively called plasma, that fly out into the vacuum of space at speeds of 200 to 400 miles per second (300 to 700 kilometers per second). These waves of plasma make up the solar winds that spread across our solar system. Traveling across freezing space should suck all the heat from the plasma by the time it nears Earth, but the solar waves detected near our planet are still hot. Scientists think something is happening within the [...]

There are a lot of neat creatures living in the ocean around Antarctica: not just whales, seals, and penguins! There’s quite a diversity of invertebrates (animals without backbones) living on the ocean floor. We call these benthic invertebrates. (“Benthic” means they live on the bottom.)There are several scientists at Rothera who study these benthic invertebrates, and they shared some of their animals with me. There are some animals you are probably familiar with: sea stars (or starfish), [...]

Hole Punch Clouds Over Maryland

This “Hole Punch Cloud” was spotted over Somerset County Maryland today, and the technical name meteorologists use is “Fall Streak Hole”. They are rather rare, and happen when super-cooled water in a cloud suddenly freezes. The freezing can be started by the introduction of some ice crystals and then the super-cooled water freezes, and falls out as ice crystals. Liquid water at temperatures well below freezing is actually fairly common

2014 Poised To Take Title as Hottest Year On Record

It is almost certain now that 2014 will be among the hottest years on record globally. The NASA (and NOAA), numbers are showing that it will likely be the absolute hottest, but it does depend on December temperatures. It would have to be an unusually cool December globally for a record to not be reached, and that is very unlikely based on how how warm the oceans are right now. | Impressum
