Weather Radar Sees Birds and Bugs Take Flight After Quake

Almost all of the NOAA Doppler radars are being upgraded to a new technology called dual polarization. Simply put, the upgraded radars can send electromagnetic radio waves that are polarized  both horizontally and vertically. Comparing the difference in the reflected energy allows forecasters to see much more than with conventional Doppler radar. One BIG benefit is the ability top determine the shape of objects in the beam. Is it hail, …

Earthquakes Saturday and Tornadoes on Monday- Wild Times in Oklahoma!

  What’s going on in Oklahoma?? The biggest quake in Sooner state history hit on Saturday (I was video chatting with my daughter on our iPhone’s as it happened). Today, I get a call from a friend, (who is a fellow meteorologist) and he’s chasing a tornado near Snyder, Oklahoma! Tornadoes in November are rare anywhere. Especially so in Oklahoma! Now you know why so many meteorologists come from Oklahoma. …

Oklahoma Rocks! After The Summer Bake, Sooners Get A Shake!

Remember “shake and bake” chicken? Well Mother Nature seems to have it backwards, because after a summer of being baked, Oklahomans just got the shake! A magnitude 4.8 quake hit near Sparks, Oklahoma at 2:12 am (07:12 GMT) Saturday morning, and even caused some damage in the nearby town of Prague. The quake was very shallow at 3.5 km depth and was felt over a large part of the state. …

Hurricanes and Quakes are Inspirational Science Moments

Every meteorologist I know can point to a big storm as the inspiration that led them into the field of atmospheric science (A blizzard in 1968 and the tornadoes of June 8,1974 for me), and this is true for other sciences as well. Neil de Grasse Tyson still has his certificate of accomplishment from the Hayden Planetarium that he now directs. The certificates are still given out and he signs …

Quake Waves Travel Across U.S. and Irene Strengthens

Callan Bentley over at Mountain Gateway here on the AGU Blogosphere has the best post on the net about the quake in VA. I saw the link to this video in the comments section, and it’s well worth a view. It’s from the Iris Transportable Array. First the quake and now possibly a hurricane? NWP Guidance this evening is indicating that Irene may skirt the Outer Banks and then come …

The Big East Coast Shake

The view from two seismographs near the epicenter. The quake has been rated at 5.9 and was very shallow at 6 km. It was felt in Montgomery, Alabama and in Fredericton, New Brunswick. Will add more data on this page soon. There are two types of earthquake waves. Body waves and surface waves. Body waves travel in the Earth and are either P waves or S waves. P waves are …

Weekend Science Digest

Images, blog posts, quotes and other geeky science things that caught my eye this week. Rivers of Ice The image above is from research published in SCIENCE this week by Eric Rignot et al. NASA released a fantastic movie that shows the flow much better:   Note to HM- Give Cox a Knighthood. The BBC reported Friday that there has been a sharp increase in the number of students taking …

Weekend Digest- New NASA App & Record Low Arctic Ice In July

  I spent much of the week in Washington,DC for a meeting of a committee that looks at the science involved with the GOES R weather satellite that will be launched in 2015 (budget allowing!). GOES R will be a totally new generation of weather satellite and will change the way the planet is monitored for weather and climate. More about this soon but here are some of the interesting …

Two Amazing Images from Space

The Chaiten Puyehue volcano in Chile continues to spew and enormous amount of ash, and has me wondering if we are getting to the point that we could see a global climate impact from the eruption. Vulcanologist Charles Stern at Colorado Univ. said back in May that the eruption was high in silica and low in Sulfur, which would negate the effects of a major global temperature change. I ‘ve …

Different Volcano, Same Problem- Ash cloud delays flights in Europe.

The NASA Terra Satellite passed over Iceland and grabbed this shot today, ( in true colour) showing the ash cloud from an erupting Iceland volcano. Click the image for a much higher res. view. The UK Met Office has just released a new ash advisory, and airlines have canceled flights into Scotland for Tuesday. I’m headed to Manchester UK myself on Thursday, so I’ll be watching this closely. The latest …
