This is a short video of some behind the scenes footage when Jim Fowler of Mutual of Omaha’s Wild Kingdom stopped by KELOLAND This Morning Saturday on September 26th.  Oh and when you watch, it was the skunk that got clunked on the way into the studio!  It was very fun to meet and talk with Jim about the animals he is so passionate about. Thanks to our super P.A. Derek for shooting the video. Enjoy!

Lights in the Sky

We received some reports on the night of Saturday September 19th of a strange light over Aberdeen.  It appears we may have found the answer.  Thank you so much to Dave A. for all of this excellent information!  The experiement put a bright light in the sky that apparently changed colors at times.Here is a picture of what people saw:http://www.flickr.com/photos/viamoi/3935870956/Twitter was active with the strange light talk as well!http://twitter.com/search?q=light+in+skyFinally here is the Explanation!From NASA:http://www.nasa.gov/centers/wallops/CARE.htmlA rocket experiment that may shed light on the highest clouds in the Earth’s atmosphere was conducted from NASA’s Wallops Flight Facility in Virginia on September 19, 2009. The experiment was launched on a NASA Black Brant XII Sounding Rocket. The Charged Aerosol Release Experiment (CARE) was conducted by the Naval Research Laboratory and the Department of Defense Space Test Program using a NASA four-stage Black Brant XII suborbital sounding rocket. Using ground based instruments and the STP/NRL STPSat-1 spacecraft, scientists will study an artificial noctilucent cloud formed by the exhaust particles of the rocket’s fourth stage at about 173 miles altitude. Ground based cameras and radars were based at various observation stations along the Atlantic coast and in Bermuda. Because of the optical observations, the launch required clear skies not only at Wallops but also at the multiple observation stations.The Spatial Heterodyne IMager for MEsospheric Radicals instrument on the STPSat-1 spacecraft will track the CARE dust cloud for days or even months. The SHIMMER instrument has previously viewed natural noctilucent clouds for the past two years. The CARE is the first space viewing of an artificial noctilucent cloud.Data collected during the experiment will provide insight into the formation, evolution, and properties of noctilucent clouds, which are typically observed naturally at high latitudes. In addition to the understanding of noctilucent clouds, scientists will use the experiment to validate and develop simulation models that predict the distribution of dust particles from rocket motors in the upper atmosphere.Natural noctilucent clouds, also known as polar mesospheric clouds, are found in the upper atmosphere as spectacular displays that are most easily seen just after sunset. The clouds are the highest clouds in Earth’s atmosphere, located in the mesosphere around 50 miles altitude.They are normally too faint to be seen with the naked eye and are visible only when illuminated by sunlight from below the horizon while the Earth’s surface is in darkness.A team from government agencies and universities, led by the Naval Research Laboratory, is conducting the experiment. In addition to the Naval Research Laboratory, participants include the DoD STP, NASA, University of Michigan, Air Force Research Laboratory, Clemson University, Stanford University, University of Colorado, Penn State University and Massachusetts Institute of Technology/Haystack Observatory.

Reflections on the World Climate Conference

We were all gathered in Geneva, Switzerland. Three thousand important people – and me.
The World Climate Conference (called WCC-3, because it was the third such gathering) brought together prominent scientists and global policymakers. The conference was held to discuss what is now called "climate change and variability," to create the basis for the Copenhagen treaty talks scheduled for December. My role was small, as a panelist in the expert segment on communicating climate information. So I was able to spend time observing and learning.
It was a fascinating process, as one might imagine, being on the inside of what will be a global debate in the next few months. For instance, we heard from the man who will be one of China’s negotiators in Copenhagen, where a Kyoto-like treaty will be hammered out. He suggested that the world should adhere to Kyoto, which the United States opposed, in part, because it gave China and other "developing countries" something of a pass from carbon emission regulations. He also insisted China (which is now the world’s biggest C02 producer) is entitled to a break because of its sizable population, and low, $2400 annual income. But – and I thought there was a bit of news in this statement – he also said he had made eight trips to the US in recent months to talk.
During my presentation, I showed some polling data regarding Americans’ views on the cause of climate change (manmade vs. natural causes), and showed how those views have evolved in the past year. (This is me on the right, listening to a colleague from Uganda.)
I also talked about the way climate information races around the internet. Not even those who study climate change and variability can keep up with it all. I put a live Twitter search up on the big screen, so everyone was able to see how often Americans tweet the words "climate change" and "global warming" along with scientific information and personal opinion. I displayed a graph revealing those terms were tweeted over 17,000 times in the previous month.
I have been to many international conferences over the years, but this one was special because the results of the World Climate Conference will form the basis for treaty talks which will affect most people on the planet. I consider myself very fortunate to be invited WCC-3, and to spend time with my weather colleagues in the great city of Geneva.Photos are from the IISD. More information about the conference is available through the WCC-3 website.

September

With Labor Day this weekend and the official end to summer later this month, I thought I’d share what a typical September brings.  Keep in mind; these statistics are from Sioux Falls since 1990. 
 
Summer heat usually continues in September as we’ve averaged nearly 2 days with 90 degree heat since 1990.  Considering we’re just getting out of our seventh coolest summer on record, and we’ve only had 4 days with 90 degree heat, I think hitting 90 this month in Sioux Falls will be a stretch. 
 
We’ve been teased with hints of fall weather late in August and early this month with some overnights dipping in the 40s, but sooner or later we know the COLD air will come, September gives most of us our first frost while some areas are lucky enough to wait until October (see Tony Barlow’s blog about first frosts from August 31).  On average, Sioux Falls will get its first overnight temperature in the 30s September 18th.  Something else about September 18th…it’s the earliest Sioux Falls has seen snow, just a trace back in 1929.  But we’ve received measurable snow as early as September 25, .3” was measured 1939.  We’ve even had temps fall to the 20s, it’s happened 6 times over the past 19 years!
 
I’m not saying we’ll see snow or temps in the 20s this month, but it has happened before!

August 2009

Here are some thought on our cool August…
 
The month helped Sioux Falls crack the top ten for coldest summers at number 7 with an average temperature of 67.5 degrees!  Below is a list of the top ten coldest summers (June through August).
            1…63.8   1915
            2…66.2   1992
            3…66.9   2004
            4…67.2   1903
            5…67.3   1950
            6…67.4   1985
            7…67.5   2009, 1951
            8…67.6   1945
            9…67.7   1902
            10..68.1   1897
A “normal” summer gives an average temperature of 70.4.
 
While the month didn’t give us any record lows, our temperatures remained cool throughout the month.  We had our highest number of days in the 70s for the decade with 18, when we usually get around 10.  The second half of the month gave Sioux Falls just one day in the 80s, which happened on the 24th.  We had only one day with the high temperature in the 60s, but the last two days were close to staying in the 60s but we squeaked away with a high of 70!  Overnight lows were easy on the air conditioner as we had 15 nights in the 50s and 4 nights in the 40s.  
The cool temperatures helped keep moisture in the ground, a good thing too.  We were about an inch below average.  The most rain Sioux Falls received was August 19 with 0.91”.  We had 11 days with measurable rain, which ends up being 3 days above our average of 8 days of measurable rain for the decade.
Tony Barlow has a look at September here.
