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 [...]
The coldest air of the winter is about to head into the Midwest and NE U.S. over the next few days. A 1058 millibar high pressure is going to drop into the Plains starting Monday and by Thursday morning, temperatures will fall below zero as far south as Southern Indiana and Pennsylvania. The images below are from a new experimental model run that NOAA is working on to improve their
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), [...]
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
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.
“National Science Foundation scientists are working to reconstruct the climate history of the Ruth Glacier area over the last thousand years. They’re researching the relationship between the temperatures and precipitation rates, and the response of glaciers in this area to climate changes.” Quoted from
To protect a river, you must preserve its headwaters. Agricultural development is warming streams at the headwaters of the Xingu River, in Mato Grosso, Brazil. Rising temperatures have local impacts that could cascade into regional changes, highlighting the importance of responsible land use outside of protected
This is the second summer that the temperatures have got pissy in July. Our cold winter was back to the 70's and the summers are there as well. Can't get a sun tan in my sauna!
Here is a really nice temperature graph, in that it shows error bars.
I like it because the error bars increase the farther back in time. Thus, I was not imagining that the snow drifts were higher when I was
Geoscience researchers from a dozen countries have been meeting at the Lodge on the Desert in Tucson since Sunday, working on the latest developments for the geoscience markup language, GeoSciML. We're giving them the special Arizona welcome with 108F temperatures and a Saturday night earthquake of magnitude 5.3 right after they settled into the hotel.
GeoSciML has been adopted by a
“Higher-than-average snowpack, climbing temperatures, and an increase in the wet and wild rainstorms called microbursts are saturating slopes and taking the brakes off masses of unstable soils.” Quoted from The Denver
“A combination of rising temperatures and ash from Northern Hemisphere forest fires caused the large-scale surface melting of the Greenland ice sheet in 1889 and
There has been a lot of strange weather this spring. Temperatures in North Dakota reached -60°F — which is about the same temperature at the surface of Mars, and about 50°F colder than the North Pole on the same day. … Continue reading
The holy capital of the Islamic religion is the ancient and beautiful city of Mecca. Located in the desert climate of Saudi Arabia, with temperatures often exceeding 45 degrees Celsius, this is the last place you would expect to experience … Continue reading
In 2012, temperatures at the summit of Greenland rose above freezing for the first time since 1889, raising questions about what led to the unusual melt
Before you say, that’s cool and move on, think about that for a second. WE CAN MEASURE WINDS FROM SPACE! We can also measure temperatures, humidity, the amount of dust in the air, and even how stressed the plants in a drought are. Oh, and NASA did it all (and went to the Moon and Mars, and launched 100 space shuttles), all on less money than we spent on the
Dr Duncan Muir Post-doctoral research assistant, Uppsala University PhD title “Investigating Magma Storage Conditions at Uturuncu Volcano, Bolivia” 1) The Twitter Challenge: Describe your PhD in 140 characters Investigating pre-eruptive magma storage conditions (pressures and temperatures) of magmas beneath Uturuncu, an actively deforming volcano in the Andes of Bolivia. 2) Where are you now?
WSDOT released an update on February 7 with some conclusions regarding the blockage that has stopped the Alaska Way Viaduct Tunnel Boring Machine, Bertha's progress since December 6. Now they don't think it was necessarily the well casing after all.
They cite two factors that contributed to the blockage. First, the cutterhead was clogged with material. You can see an cool short video of a worker unclogging the cutterhead. Not terribly dramatic, but still cool. The second factor was [...]
This has been a trying winter here on the east coast for working outside. I got spoiled by the last couple of winters, which were generally mild.
Here's what has worked to keep me warm when the temperatures have hovered around zero (F), starting from the inside and working outside:
1. single-layer longjohns (I have a pair of the two-layer wool pants, but frankly, I can only wear so many
Mount Sinabung, located in northern part of the Indonesian island of Sumatra has been undergoing near constant eruptions since September last year. A pyroclastic flow is a superheated (often with temperatures in excess of 500 degrees Celsius) dust and debris … Continue reading
“Despite some difficulties, the project was able to drill down into the molten magma and control it; it was possible to set steel casing in the bottom of the hole; allowing the hole to blow superheated, high-pressure steam for months at temperatures exceeding 450 C, created a world record for geothermal heat.” Quoted from the
