SUMMARY OF CLIMATOLOGICAL DATA 



NOVEMBER 2012

...COLD & DRY...

 

  • WIND CHILL: "BABY IT'S COLD OUTSIDE!" (from CoCoRaHS)       When the wind blows it often feels much colder than what the thermometer says. One way to quantify what you are experiencing is known as the "wind chill factor". The AMS Glossary of Meteorology defines it as: "a means of quantifying the threat of rapid cooling during breezy or windy conditions that may result in hypothermia in cold conditions." In 2001 the National Weather Service revised the "windchill index" that many of us are familiar with. To find out more about windchill visit: "The Windchill Page". And one last thing . . . remember to wear a hat! http://www.nws.noaa.gov/os/windchill/windchillglossary.shtml


  • WHAT "TYPE" OF PRECIPATION IS FALLING BY YOU? (from CoCoRaHS)       NOAA's NSSL appreciates your help! NOAA's National Severe Storms Laboratory (NSSL) is located in Norman, Oklahoma. They study severe and hazardous weather processes and develop tools to help National Weather Service forecasters, and federal, university and private sector partners use weather information more effectively. NSSL has launched its iPhone and Android apps to collect precipitation reports from the public. The NOAA National Severe Storms Laboratory, in partnership with the University of Oklahoma has launched an app where users can anonymously report precipitation from their iPhone or Android through the "mobile precipitation identification near the ground "mPING" app. NSSL researchers will compare the reports with what radars detect and use the information to develop new radar and forecasting technologies and techniques to determine whether snow, rain, ice pellets, mixtures or hail is falling. NSSL hopes to build a valuable database of tens of thousands of observations from across the U.S. The apps are available on iTunes or Google Play for use on both phones and tablets. The reports can be viewed here in real-time: http://www.nssl.noaa.gov/projects/ping/display/

    The lab's main PING page: http://www.nssl.noaa.gov/projects/ping/

    Link for iTunes app: https://itunes.apple.com/us/app/mping/id584383400?mt=8

    If you have some extra time please give this a try, NSSL would really appreciate your help!


  • WEATHERFUN Yahoo Group (from Kevin Shaw, member ACON - DC/MD/DE)       I have been a long-time member of the WEATHERFUN yahoogroup. Not terribly technical most of the time, plenty of fun weather contests, plus posting of current weather events and what is going on, weatherwise, in your own backyard. And so much more! It is free, and easy to join. We have suffered some losses of late, two key members passed away on exactly the same date this fall. And the founder, Jerry Laroche, has had frequent health setbacks that has severely limited his online participation. Bill Kaler, second in command, asked me to put out the word about WEATHERFUN, and see if any of you might be interested in joining. No requirements, no fees, just a love of weather and some fun. You can get a lot more details about it on the WEATHERFUN website, http://www.weatherfun.com. On the website there is a button to click on to join the WEATHERFUN group. There is somewhat of a concentration in members in the NY and New England area, but there are members all over the US and Canada, and a few in other countries also. And anything you happen to be into "in weather" can be brought up through a WEATHERFUN Yahoo Group email to all the members to let a big audience to know all about it. Nothing commercial generally, focus is more on educational type information. I have asked some of you to consider joining in the past, please reconsider this now, give it a try. A lot of weather, a little bit of fun, great networking with some great people, and you will learn more about the weather in ways you never would have imagined. If you don't want to at this time, that's fine too - then have a Happy Holiday season and see you around. Any questions let me know, or email Bill Kaler, at weather123@verizon.net. Thanks!


  • ARE YOU FAMILIAR WITH THE U.S. DROUGHT PORTAL? (from CoCoRaHS)       When we think of the December holiday season, most of us don't picture a dry Christmas tree covered in dust do we? We usually think of lots of snow, but this year many places are lacking the fluffy white stuff on their trees. "Drought is one of the most costly natural disasters affecting the U.S. The National Integrated Drought Information System (NIDIS) was established in 2006 (NIDIS Act) to help begin to move society from a reactive response to drought to a proactive stance. NIDIS was envisioned to be a dynamic and accessible drought information system that provides users with the ability to determine the potential impacts of drought and the associated risks they bring, and the decision support tools needed to better prepare for and mitigate the effects of drought. In this, NIDIS forms the backbone of a national Drought Early Warning System and the U.S. Drought Portal is the public face of NIDIS on the Web." You may not realize it, but CoCoRaHS precipitation observations play an important role along with other factors in helping our friends at NIDIS determine where drought conditions exist. Especially important are those zeros when nothing falls from the sky and your comments on how the conditions are impacting you. To visit the NIDIS Website and learn more about the portal click here: NIDIS - http://www.drought.gov/drought/. Please take a few moments and share the NIDIS Portal website with others and keep up the good work by sending in your precipitation reports -- rain, snow or shine!
