Measuring the temperature of solar winds 

AGU Meetings [2015-01-05 16:16:13]  recommend  recommend this post  (26 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 [...]

The Dogs of Winter Are Getting Ready To Howl!

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), [...]

Hole Punch Clouds Over Maryland 

Dan\'s Wild Wild Science Journal [2014-12-04 23:30:09]  recommend  recommend this post  (24 visits) info

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.

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

Another cold July

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

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

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 [...]
