Doppler Radar Sees Debris from Antares Explosion

The NWS Doppler radar at Wakefield,Va detected the debris from the Antares explosion Tuesday evening. Not only that, but it was able to show that this was not rain but debris in the air. Being a dual polarimetric radar it can detect the shape of the particles in the radar beam, and a product called the correlation coefficient showed that the echo was made up of particles that were of …

Antares Explodes At Wallops. Explosion Heard/Seen for 50 Miles.

Here is how the explosion looked as WBOC covered the Antares launch and explosion live. This was likely one of the largest rocket explosions ever at Wallops. The reason is that it happened with a fully fueled vehicle, carrying 5,000 pounds into orbit. Most other failures at Wallops were either non-orbital launches, or carrying much lighter payloads. The blast lit up the clouds and was seen across almost all of …

Saharan Dust Storm Below Towering Thunderstorms

Here are the particulars of the image, and what you are seeing from NASA Earth Observatory: More dust blows out of the Sahara Desert and into the atmosphere than from any other desert in the world, and more than half of the dust deposited in the ocean lifts off from these arid North African lands. Saharan dust influences the fertility of Atlantic waters and soils in the Americas. It blocks or reflects …

Wildfire Smoke Makes Cool East Coast Temps Even Cooler

In spite of an unusually dry and cool air mass over the eastern seaboard of the U.S. this afternoon, the sky is a milky white due to smoke from the wildfires in Western and far northern Canada. An even denser layer of smoke covers the western portions of Hudson Bay as well. Here is the view of the sky over Maryland at 630 PM, and the usual deep blue sky …

The Only Thing More Amazing Than The Moonwalk 45 years Ago Tonight

Exactly 45 years ago tonight, everyone who could see a TV, was in front of one. The clip below is the actual coverage from CBS News that evening. You can actually watch all of the Moonwalk online, and if you were not born yet, I highly recommend you do so. A lot of folks do not realize that when the camera came on (and a lot of folks doubted it …

Super Typhoon Neogori Heads toward Japan.

The typhoon should weaken before hitting Japan, but Kyushu (southern most island) will get a ton of rain and wind. Flooding rains have already been reported earlier in the week so the soil is already saturated. ISS Astronaut Reid Wisemen sent back this shot of an oddly shaped eye on Neogori. (Perhaps related to the fact it was undergoing an eye-wall replacement cycle.)

True Colour View of Arthur from NASA (Doppler sees winds at 100 MPH)

Frying Pan Shoals off the North Carolina coast caught a gust to 99 mph on their weather station. They were in the eye-wall of Hurricane Arthur at the time. Here on the Delmarva Peninsula there is a real risk of extreme rip currents behind the storm. With thousands of folks streaming to the Maryland and Delaware beaches for the holiday weekend, this is a serious threat. Something to think about: …

This Research May Give You Better Warning Of A Dangerous Storm

TV Viewers are quite familiar with seeing lightning on radar displays these days, and knowing a storm is producing a lot of lightning as it approaches a large metropolitan area, is vital information for everyone from a power company to a baseball coach. Many times I can almost guess at how many power outages will develop based on the lightning I see with a storm. It’s a simple function of …

Some Amazing Pics Of Earth

  NESDIS is now producing some incredible Earth imagery using different satellites with some of the most sophisticated radiation sensors in orbit. I thought I would share  a couple with you. Click for the BIG image. One is a view of the USA taken Saturday afternoon June 7. The other is the sea temperatures around North america and the other shows the temp. anomalies. This allows you to see where …

Predicting Weather & Climate- Gavin Schmidt’s TED Talk is A Must See

I use atmospheric models everyday, and without them the forecast you see on TV or online everyday would be worth little beyond about 48 hours (it would not be very accurate within that time period either). These days, a seven-day forecast will verify much better than a three-day outlook was in the 1970′s, and the improvement continues. Unfortunately, some people see these models as untrustworthy black boxes, and have little understanding …

Oh, The Things You Can See From On High

I spent a little while looking at today’s images from NASA’s Terra and Aqua satellites with their amazing MODIS imager that sends back true colour images from an altitude of around 700 km. Here are a few things I spotted in just a short period of browsing this evening. Click any image for a much larger view. Here is a view of just some Sahara sand blowing north into Greece …

Suomi Satellite Night Vision Sees Great Lakes Ice

The CIMMS Satellite blog has posted a fantastic image of the ice cover on the Great Lakes. See my previous post for more info. This is a visible light (not IR) image made by the VIRRS sensor on Suomi is below: (click for full resolution)

Happy World Meteorological Day

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 …

Severe Travel Restrictions Imposed In Paris as Smog Worsens

Paris just cut the vehicles on Monday’s roads by half in an effort to improve the air quality over the Capital. It also has made all mass transit free, and the BBC has further details here. Motorcycles (most of who have rather dirty engines) are also included. The reason for the bad smog is a temperature inversion, and you have likely heard this before, but I want to explain WHY …

The grapes of Landsat

California’s persistent drought is forcing grape growers to keep a more-attentive-than-normal eye on their vines, as water shortages and elevated temperatures alter this year’s growing season.

Video of the X Class Flare

You heard about the big X4.9 solar flare at 00:50 GMT Monday I suspect. Phil Plait at Bad Astronomy is always the go to person on that, but NASA has a video out of the fare in different wavelengths that is pretty cool. The sunspot that produced the flare is rotating slowly around, and will be facing Earth in a few days. If it erupts again then we may be …

2014 is NASA’s “The Year of Earth”

From the NASA Earth Right Now website: With the launch of five Earth-observing missions in 2014 — more Earth-focused launches in a single year in more than a decade — NASA will be able to deliver even more crucial data to scientists trying to understand our changing planet. Since the agency’s inception in 1958, NASA has established itself as a world leader in Earth science and climate studies. It is …

Icy Shots From Space

How can you tell the difference between white clouds and white snow on a satellite image?? Rivers don’t run through clouds! Study the image from the Aqua satellite today above and you will see what i mean. Speaking of satellite images of icy cold, the folks at CIMMS at the Uni. of Wisconsin posted the animated gif below showing ice forming on Lake Michigan. Speaking of ice, I had a …
