  • Third Annual Severe Weather Awareness Day Wrapup

    Despite the chilly north winds yesterday, we had a large turnout for the 3rd Annual Severe Weather Awareness Day!  An estimated 1000 people showed up to check out all the equipment and various weather related science exhibits the Texas Tech AMS group were showing off, much to the delight of kids both young and old.

    As I mentioned before, we brought our chase vehicles out to let people get an up close look and ask all the questions they wanted about storm chasing. Texas Tech brought out their new mobile radar, which is very nice, and while I listened several times to Jerry Guynes (the guy that built it) talk about all the technical details, I am still trying to let my brain digest it.  He’s an incredibly smart man when it comes to mobile radar, and his passion for what he does shows through.  I felt like I came away “an order of magnitude” (as he likes to say) smarter just being in his presence! He is a faculty member of the Texas Tech Wind Science and Engineering team.

    Ian Giamanco was displaying the Texas Tech Severe Storm Research Team’s “sticknets” and mobile mesonet.  They have two trailers full of these things they can deploy in short order and take all the standard measurements.  One survived the onslaught of Hurricane Ike planted on the Bolivar Peninsula even.  All of these things are going to be a large part of Vortex 2 out this year.  Storms will be surrounded, interrogated, probed and infiltrated by more scientific devices that ever before in our history this year!

    Inside things were a little less technical but still fun, especially for the kids.  The various simplified demonstrations of how weather works created a large crowd of big eyed kids.  One kid that came out to check out the chase vehicle not only knew what GRLevel3 was (a radar program we use), but he has a copy of it and GRLevel2AE, and he knows how to use them.  We had quite the discussion about placefiles and video streaming.  I believe in the future we will see him out on the road chasing storms!  Oh did I mention he was only about 10? (He didn’t tell me how old he was, I’m just guessing).  I was very impressed!

    Demonstrations showed various things, like how a tornado vortex might form, how to identify various types of clouds, how light refracts in the atmosphere, and they even had a miniature version of their Debris Impact Simulator.  The South Plains Storm Spotting Team was on hand showing some great video from the big tornado day out here in 2007.  The National Weather Service of course had a big presence, being that they are in the same building, and were giving guided tours of their offices, as well as a storm spotter class.  The Red Cross was also on hand.

    Last but not least, KCBD NewChannel 11 was of course there helping folks program their weather radios and answer questions about the new Digital TV switch, as well as John Robison, Steve Divine and Cary Allan, the meteorologists were there to talk to people and answer everyone’s questions about weather.  Kids always enjoy a chance to meet their favorite on-air meteorologists they watch on TV all the time. John was handing door prizes and my chaser friend Steve Miller Amarillo won a NOAA Weather Radio.

    The old IMAX “Storm Chasers” movie was also being shown in the IMAX theater.  While it’s a bit outdated now, it was the first time I have seen it in an actual IMAX theater.  The whole theater rumbled when the tornado came on stage!  I noticed in one scene they were at an intersection only about 7 miles from my house!

    What a great “weather weenie” day and it sure put me in the mood for severe weather season, which starts officially for me…TODAY!

    I was able to get a number of interviews with various exhibitors at the Severe Weather Awareness Day, and have posted them on my YouTube Channel.  There are 7 videos from this even in total:

    1) Introductions

    2) Sunlight & Tornadoes

    3) Debris & Lightning

    4) Texas Tech Mobile Radar

    5) Texas Tech Sticknets

    6) National Weather Service

  • Update on FedEx Plane Crash in Lubbock, TX Weather Related?

    fedexplane1

    The NTSB has released their preliminary report of the FedEx plane crash I first told you about back on January 27th, 2008.

    What follows is the content of their report:

    NTSB Identification: CEN09MA142
    Nonscheduled 14 CFR Part 121: Air Carrier operation of Empire Airlines
    Accident occurred Tuesday, January 27, 2009 in Lubbock, TX
    Aircraft: AEROSPATIALE ALENIA ATR 42-320, registration: N902FX
    Injuries: 1 Serious, 1 Minor.

    This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed.

    On January 27, 2009, approximately 0437 central standard time, N902FX, an Aerospatiale Alenia ATR-42-320, operating as Empire Airlines flight 8284, sustained substantial damage when it landed short of the runway threshold while executing the Instrument Landing System (ILS) RWY 17R approach at Lubbock Preston Smith International Airport (LBB), Lubbock, Texas. The airplane was registered to Federal Express Corporation, Memphis, Tennessee, and operated by Empire Airlines, Hayden, Idaho. The airline transport pilot rated captain was seriously injured and the commercial rated first officer sustained minor injuries. An instrument flight rules flight plan was filed for the flight that departed Fort Worth Alliance Airport (AFW), Fort Worth, Texas, approximately 0319. Night instrument meteorological conditions prevailed for the supplemental cargo flight operated under 14 Code of Federal Regulations Part 121.

    A preliminary review of air traffic control communications revealed that the captain contacted the Lubbock Air Traffic Control Tower (ATCT) at 0422, and reported that they were descending from an altitude of 10,000 feet down to 8,000 feet mean sea level (msl). A controller acknowledged the transmission and then provided the airport’s current weather information and a runway breaking-action advisory. In addition, he provided vectors for the ILS 17R approach.

    At 0430, the controller instructed the airplane to descend and maintain an altitude of 5,000 feet msl. At 0432, the controller informed the flight crew that the wind had shifted 180 degrees from the north to the south between 5,000 and 6,000 feet msl. The captain responded and added that he also noted a drop in the outside air temperature of 8 degrees and concurred with the controller’s observation regarding the wind shift. The controller cleared the airplane for the ILS approach at 0433 and instructed the flight crew to contact Lubbock Control Tower. The captain acknowledged.

    At 0434, the captain contacted the control tower and a controller cleared the airplane to land on runway 17R. The captain acknowledged the landing clearance and there were no further communications. Approximately three minutes later an airport maintenance employee contacted the tower and asked “what is that fire there at the end of the runway?” A controller responded, “it’s an airplane.” The controller had witnessed the accident and had activated the alarm for the airport rescue and fire fighting equipment to respond.

    An on-scene examination of the wreckage revealed that the airplane landed short of the runway threshold and collided with the approach lighting system before it skidded off the right side of the runway into the grass. The airplane came to rest on a westerly heading perpendicular to the runway. A post-impact fire consumed a large portion of the fuselage and the right wing.

    At 0415, the special weather report at LBB included wind from 350 degrees at 10 knots, visibility 2 miles, light freezing drizzle, mist, ceiling 500 feet overcast, temperature 46 degrees Fahrenheit, dew point 48 degrees Fahrenheit, and a barometric pressure setting of 30.02 inches of Mercury.
